    thx! Did my first bake a year ago for a 4850 card, it lasted only few weeks.... could use it with pink lines a while... found your channel few weeks ago and gave a try with the 6970M on my late 2009 imac. Works great. thumbs up for you channel and all the ressources !

    I have been following your excellent guides and I am still at the 'first bake' stage - successful so far!
    The original upper ventilation slot was so ridiculously narrow, that it had to be increased. So I enlarged it by drilling two holes ( about 8mm) at either end of the existing slot and then using an angle grinder, cut away the metal strip between. This can be done with all the internal boards in place if one masks up the internal grill to stop any debris getting inside - obviously the screen was removed! Cleaned up with a file and then after suitable masking up, lightly spray with a suitable silver car paint. The result is a doubling of the upper ventilation and so the GPU runs at a max of 45C with MacFan.

    Hi There! I saw your first 2 bake videos a couple of years ago and I finally got around to doing it. I was so disappointed that my 27 inch iMac failed. I have a mid 2011 with the 6970m video card. I baked it as your first 2 videos described and it worked! We’ll see how long it lasts but when it comes time to bake your new card rest assured it works with them too! THANKS SO MUCH!!!!!

      Thank you for sharing your success story, Michael. I am especially interested in hearing reports from you over time as there are many more people who are baking the older 4850 cards. I am interested in knowing how long the bake lasts on the 6970M like you have. Best wishes to you and your newly resurrected iMac!

    As an alternative to the microfibre lens cleaner, I cut off about 2 inches of domestic cable, removed the internal wires and then slit the outer sheath lengthwise and glued this onto the rough plastic left by the enlargement shown at 7.00.

    suggestion, get a length of old 'electrical cable stripped out', keep the sleeve and slice it down its length, cut to size/length for the sharp widened channel, fit the cable sleeve over top and bottom of the cut and superglue in place - back and sides allowing you to dispense with the cloth and cable ties...

    • @JDW-
      @JDW-  4 года назад

      Thank you for posting that suggestion, Jamie. Your suggestion does involve a bit more work and requires superglue too, but of course your solution would be a bit more robust than my microfiber cloth and wireties. But I think what people who watch my video and read your suggestion will begin to consider is their own unique solution based upon the parts and tools they have on hand. There is no one perfect way to do this. It’s just a matter of cutting out that plastic piece and then making sure any jagged edges don’t damage the back of the cable. That’s pretty much it.

    Buying broken and baking can save big bucks. I am three for three so far. AMD 6970M part numbers are confusing. 109-C29647 is 2GB. 109-C29657 can be either 1GB or 2GB. Could the -57 cards be newer production cards fitted by Apple replacement program? I have bought -57 cards identified as 1GB but were in fact 2GB. I am trying to figure out how to reliably identify which -57 cards have 2GB. Cards with Hynix VRAM and -MFR suffix might be an identifier. My 2GB -57 has -MFR memory. I have seen 1GB cards with Hynix -AFR. Ideas? Having run both, 2GB makes a difference and is worth having.

    Congrats on the new/used GPU looks like its working great, more life into an old iMac. On my Late 2009 iMac 27" i5 I have been following these videos waiting for my paste to try a bake on the ATI Radeon HD4850 GPU, but also purchased an ATI Radeon HD 5670 512MB 661-5799 off E-bay that has the same matching GPU with 2 pipe Heat sink (should fit without modification) for under $100 tested to work. I know only certain GPU cards will work with the 2009 27" iMac hoping the new one is one of them. Again I glad to see yours back up and running Apple should have had a better way of designing without all the internal heat killing the GPU most of what I read on the Internet that 3 years before fail was the norm and Apple had a recall to replace for those that did, but that has run out.

    Hi, great video. Wondering if this card will work on 27-inch, Late 2009 3,06 GHz Intel Core 2 Duo ?. The original card on this machine is an ATI Radeon HD 4670 256 MB. The Hong Kong seller now seems to have the 6970M listed again but it doesn´t seem to come with the heat sink included.

    • @JDW-
      @JDW-  2 года назад

      I'm not sure because I don't own a Core 2 Duo and there's no information that I can find which suggests that a 6790M would work. Even on iFixit, there seems to be conflicting info about whether it would work. bit.ly/3I28118 When in doubt, I would suggest assuming it doesn't work. The only way to know is if you can find a person who has first hand experience to prove that putting a 6970M inside a Core 2 Duo iMac works.

    Ah - that's interesting. I mentioned on your 2009-2001 iMac video card bake & 6970 update video, that I have also fitted a 6970 in my late 2009 i7 iMac, and it works beautifully - but the iMac resets several times after switching on from cold - sometimes it fully boots, sometimes, it restarts before boot is complete. Often, it's just after opening a browser to watch some RUclips. Sometimes, it's as much as twenty minutes later, or after waking from sleep. It usually settles down after the iMac has been left on for a good half an hour. BUT - the tutorials I followed didn't make mention of cutting that plastic shield behind the wiring loom. I didn't do that - and I'm now wondering if that means the plastic is pushing the video card enough to break the electrical contacts - causing it to restart.
    I had wondered if it was a bug in Sierra, which I'd read about. But it was also happening under High Sierra. So, I'm more inclined to think it's related to the video card. I'm going to have to open it up again and address that - will let you know how I get on.

    • @JDW-
      @JDW-  4 года назад

      At 2:35, I show the required cutting you are talking about. I can't imagine what would have happened had I tried to fit that triple-heatpipe heatsink into my late 2009 27" iMac without cutting that plastic piece. The sheer pressure on that back side of the heatsink must be putting the video card's connector under a lot of stress. Seriously, I would not rule that out as being the root cause of your troubles. I know it's a real pain to open these iMacs -- I know! But in your case, I would strongly recommend following my video to cut out the relevant section so the stress is eliminated on that video card to motherboard connector. If the issue then persists in your subsequent testing, then you can know if the root problem is really the GPU chip. Remember that the 6870M series also had issues. Apple replaced a lot of them. I get 6970M owners tell me that baking them tends to work just like it does on the 4850. I am not suggesting you bake your card right now. I would advise starting with cutting that plastic first.

    • @JDW-
      @JDW-  4 года назад

      I have not run those specific tests, but before re-pasting I would get shut downs when the temperature reached 68°C. After re-pasting it shuts down at about 78°C. But by keeping all three fans running at 2000 RPM I can avoid having the temperature go that high.

      @@JDW- Update: I have since learned that my system had been shutting down in the low 90 to mid 90s at shut down. Evidently the OSX apps are for some reason not giving you accurate temp data. To get the accurate readings you need to be in bootcamp and download and run this app on bootcamp: TechPowerUp GPU-Z at www.techpowerup.com/download/techpowerup-gpu-z/ When you run the Valley benchmark (NOT fullscreen to see the utility), you run the TechPower app and click the tab Sensors. There you will find listed the gpu #1, #2, and 3# true temperatures. I have concluded that the open box new card's paste degraded over time and it obviously requires re-pasting.

      @@dwood5494 Thank you for sharing that information. I have tried iStatMenus, MacsFanControl, and smcFanControl, as well as used Terminal commands. All seem to give about the same readings. I don't do Windows so I've not tried Boot Camp. However, I cannot imagine that all Mac apps would give wrong values. I suspect that when running Windows there are numerous differences in CPU and GPU access (and perhaps even fan speed control) which would likely contribute to a difference in temperature measurements.
      All said, after repasting with Thermal Grizzyly Kryonaut on the GPU and K5 Pro on the memory chips, the card can run up to the mid 70's in °C without shutting down. In the high 70's, it does cause the iMac to suddenly power off. But thus far, I've not had many people try to run their 6970Ms into th high 70's or hotter to give me a good enough data pool to know if my card is unique or not. If my card is unique as far as a 6970M running inside a late 2009 iMac goes, then the only thing I can think that could be the cause is the firmware. I only assume that because someone said the little red things at the edges of my GPU show it is a PC card, not an Apple card. I don't know if that is true or not though. If true, it means my card was flashed, and such could mean the flashed firmware may not be an exact clone of the firmware used on Apple's edition 6970M card.
      For now, I am happily using the 6970M with all 3 fans running at 2000rpm in combination with an ambient room temperature that does not exceed 28°C in the summer months.

      The graphics cards supported by the 24" Early 2009 iMac Core2 Duo are shown here: support.apple.com/kb/sp507?locale=en_US
      Using a different video card would only be an experiment since Apple does not support it. In my case, I had read of success stories with the 6970M (from a 2011 iMac) used in a late 2009 iMac i7, which is the only reason I tried it. I found that the 6970M does work in my older iMac. But most of my iMac videos are not about that. Mostly, I try to help people to resurrect their existing graphics card using an oven bake method. Even people with 2008 iMacs have told me the oven bake works. So you may wish to try that instead. I don't have personal experience with the Core2 Duo model, so I cannot say from experience which is the best non-stock graphics card for you to use.

    Hello there, A while ago I got a late 2009 iMac 27" from a neighbour who moved out. He told me the videocard probably died. The drive was removed so I installed a 1.5 TB hdd in it. After reinstalling os X lion (the only version of macOs I had ) the screen kept going completely dark after only a few minutes after powering it on. Stayed black after turning it on again too. Looked like an overheating issue or malfunctioning component. Not willing to spend any money on an 11 year old machine, I attached an old external disk and installed Ubuntu 20.4 on it. I had nothing to loose and at least this way I eliminated any overheating caused by the internal hdd. I've been booting from this external drive eversince and the screen blacking out issues vanished. It works like a charm now. It runs for 8 hours straight with a max temp of 69 on the gpu heatsink sensor, fans running at 2000 rpm. Fast and with an up-to-date OS and without software upgrade limitations. Perhaps I will look into a different videocard anyway. Does anyone know if an nvidia 9300m mxm card will fit?

    • @JDW-
      @JDW-  4 года назад

      When you have a bad video card in these old iMacs, you may be able to see video when you boot macOS into Safe mode. But that doesn’t mean the video card is OK. Ditto when booting into a less graphically demanding OS like Ubuntu.
      Getting Nvidia MXM cards to “fit” is not an issue. But doing so requires firmware flashing of the card, and in many cases that requires a Windows machine. That is why I have never gone that route.
      Baking the video card is the cheapest thing you can do. You can only bake so many times though, and after that you need to replace the video card. I chose the 6970M after I could no longer bake my 4850 card back to life because the 6970M is an Apple Card that, even though it too has its own set of problems, does work decently enough in the iMac, so long as it doesn’t get too hot.

      I read through both links, and your Second link is the most relevant. But I see that you lose Wi-Fi in the process, and querty0 reported some kind of incompatibility with his version of macOS, which would be one of the biggest concerns about that hack.
      All said, if you don’t care about Wi-Fi and if you’re content with running Mac OS X Yosemite, the hack outlined in that thread would probably work for you.
      Personally, I like running high sierra, and I’m not sure if adding a kernel extension would work at all in that version of the OS. Another problem for me would be that I would lose Wi-Fi and I have my iMac in a room with no ethernet and no access to the Internet via cable connection.

But I have removed and installed video cards so many times in my iMac now that I am a real pro at it. I can remove it and reinsert it in less than 20 seconds. I did it just yesterday, in fact and timed myself. I use tweezers to put the little connector just in front of its mating connector, and then I use my two index fingers to press on the little protrusions (wings) at the back of the connector, pushing toward the back of the motherboard, thereby inserting the connector into its socket. To remove, I use my two thumbnails on the same little plastic wings at the back of the connector to slowly wiggle it out. It takes practice, but as they say, practice makes perfect!

      The chips have a maximum 100°C specification, so Apple designs its machines to ensure that threshold is not crossed. I reach those temperatures on my mid-2015 15" MBP all the time, but I've not had sustained temperatures in the high 90's in my 2009 iMac though. I use a fan app to keep all 3 internal fans running at 2000rpm, and on hot days I make sure the room A/C is switched on. Even so, if the GPU or CPU gets close to 100°C, then you will see performance hits. The only solution is to keep the machine cool.
      One last thing. If the thermal paste applied to the GPU and/or CPU is old or if it was improperly pasted, that can easy cause higher than normal temperatures. If you watch my 2nd Bake video, you can see how I repasted the stock Apple 4850 video card. It, like the 6970M and all stock iMac cards from 2009 to 2011, require two different kinds of thermal paste, for reasons I mention in that video.

      ​@@camcappe353 I recommend the K4 Pro paste for the GPU and the K5 Pro for the memory chips because I used that combo for 2 years and 9 months with success after my 2nd bake. You must never use K5 Pro on CPUs or GPUs because thermal transfer is lower -- it's made to fill gaps between low-heat memory chips and heatsinks, which is precisely what you have with older iMac video cards. The heatsink touches the GPU though, so you need a normal CPU/GPU paste for that. Thermal Grizzly Kryonaut is the best paste you could possibly use (as a non electrically conductive paste), but K4 Pro will work, and if you buy the K4/K5 bundle it's kind of a waste not to use K4 Pro. But there are some people who want the absolute best, so they either buy the K4/K5 Pro bundle and only use the K5 Pro on the memory chips and then buy Kryonaut for the GPU, or they buy only the K5 Pro only and the Kryonaut only.

      It's always worth doing a repaste, but I doubt it would prevent GPU issues. You see, the graphics cards used in 2008 to 2011 iMacs had a design defect. Whether cooling matters or not is merely theory. The problem may occur even if you repaste. However, repasting would make the card run cooler.

      I lot of people mistakenly think the solder balls are the problem, when in fact it is a flaw inside the GPU chip that is fixed (temporarily) with heat. This is why baking works as well as reballing. But even a brand new video card from Apple lasts only 3 years in my experience. My stock card lasted 3 years, then Apple gave me a replacement which too lasted 3 years. It was after the I started the bake. My 2nd bake lasted 2 years and 9 months. But even though the bake doesn't last forever, I think it lasts long enough to make the bake worthwhile, and it's the cheapest solution to the problem. Of course, if you buy a newer machine, that would solve the issue completely. I have a late 2015 27" iMac purchased new in 2015, and I use it at the office daily. It never gets hot, and it has no video issues. Before buying a new Mac though, consider well that Apple will release an Apple Silicon version of the iMac soon. I suggest you wait for that. Apple Silicon is the wave of the future.

That's really the biggest issue with using an Nvidia card in a 2009 iMac. You need to flash it correctly so it works properly. I'd say that if the seller offers some kind of "return it if it doesn't work" warranty, then you should seriously consider that. Also note the caveats in the description of that auction which says it works great on High Sierra, but using the card with an unsupported OS like Mojave or higher will require other software fiddling on your part.

The bake I present in my videos merely resolves the problem for a limited amount of time, which is usually enough time to have made the bake worth it in the first place.

      It’s really not that big of a difference between my old 4850 card and the 6970M card when it comes to playing back RUclips videos in 4K. Besides, the display is only 1440P anyway. 1440P videos seem to play back a little bit smoother in Chrome or Firefox than on the 4850, but it’s not 100% perfect. I think the biggest change would be the amount of memory on the card itself, which would be better for 3-D work or gaming.

The speed increase of the 6970M 2GB card over the 4850 is not really that large, especially if you are accustomed to using more modern Macs. For example, I use a top end late 2015 27" iMac at the office, and it's much faster overall. Indeed, to get a really noticeable speed improvement, you would need to buy a MXM card for PCs like the K2100M. That would physically fit the connector and you could match it to the stock heatsink (from what I have read anyway). However, it does require a Windows PC to flash the K2100M to work on the Macintosh. Some people are doing that because they want a METAL compatible card to run Catalina (which requires a patch to work). I have never tried that myself, which is why I haven't done a video on that. Should my 6970M die and not be fixable via the bake in the future, I would of course give the PC MXM cards a try. But for now, I cannot offer you specific guidance on that.
      What I can say is that the single best upgrade for 2009-2011 iMacs is a change from the stock hard drive to an SSD. It's a night-and-day performance boost. You can find links to the bracket and temperature sensor inside the text description under most of my bake videos.

      Folks who really, really want to run Catalina AND continue using their old iMacs go the Nvidia card route, using a Windows PC to flash the required firmware to the card to make it work. That's the only way to get a METAL compatible setup. I myself still run High Sierra even on my late 2015 5K iMac at the office, even though it natively supports Catalina, because I just don't like Catalina. And I say this as someone who actually does use Catalina to some extent. I bought an external 2TB SSD to plug into my mid-2015 15" MBP so as to boot Catalina for the lone purpose of running the latest version of FCPX. You can't run the latest version of FCPX on High Sierra. High Sierra is rock solid, has few bugs, and let's me use all my 32-bit apps too. Even if you bought an Nvidia card and flashed it in Windows, the fact remains your CPU on those old 2009-2011 iMac isn't that fast, so I really doubt the overall Catalina experience would be a pleasurable one. Of course, these are just my personal thoughts, so take them with a grain of salt.

But as was true in the case of my late 2009 Intel i7 iMac 27", so cutting of plastic is required to make the card physically fit.

      Even with the optical drive removed, you will find the 4850 heat sink to be inadequate because even the matching triple heat pipe heat sink for the 6970 M card doesn’t adequately cool it. So if you do decide to use the heat sink for the 4850 card on the 6970M card, you would probably need to run the fans at full blast to keep it sufficiently cooled.

      @@camcappe353 That's why I had to do. Metal parts like that won't have issues, but it's harder to determine the condition of the card. Sellers will most often say it's never been baked, but it sure looks like my 6970M had been baked, as evidenced by the fact there were scotch marks on the thermal paste! And that's another thing. Mine came with the correct heatsink, but the thermal paste job was horrible, and I didn't know that until after I started testing, found a problem, and then removed the heatsink to check. I repasted it and all was well. It's still going strong to this day. Speaking of paste, Thermal Grizzly Kryonaut is the best paste in terms of low temperatures, but it doesn't last as long as MX-4. I realize MX-5 is out, but it's not much better than MX-4, and it doesn't spread as nice as MX-4 either. So if you want to paste and then forget for the next 8 years, go with MX-4. Yep, the manufacturer says it lasts that long. Good luck!

      Because it’s from China, there’s no telling what “open box“ actually means. But if the card is in working order, and if the heat sink is truly undamaged, then the worst you would possibly need to do would be to re-paste the chips like I did. But you could test it first to see how the temperatures are before resorting to that.

    I am constantly updating this pinned comment. Comments below are filled with the most up-to-date information on how I am testing my 6970M in conjunction with a big problem I found. Sleep/Wake cycles work fine and basic email and web browsing works fine; but gaming (e.g., Roblox, LEGO Star Wars, etc.), regardless of fan speed, and watching 1080p60fps RUclips videos with fans controlled by MacOS triggers a sudden POWER DOWN. This is a complete power OFF, not a normal shutdown, and it doesn't appear on the Console logs.
    If I watch RUclips with a fan app that sets the minimum fan speed to 2000rpm for all fans, the temperature of the GPU heatsink is low enough it won't trigger the shutdown. But if I allow the GPU temp to rise above 60°C (via low fan speed), a sudden power down occurs. Games trigger the shutdown faster, even with all 3 fans on full blast.
    I asked a friend with a 2011 iMac and 6970M to repeat my tests. He did. No shutdown even though his GPU heatsink temps rose above 60°C during his testing. That leads me to believe that the late 2009 iMac (which is what I have) doesn't properly communicate with the 6970M to do whatever is necessary to prevent these shutdowns.
    Please read the comments below that are tied to this pinned comment and let me know your thoughts.

      I've been tracking your videos for awhile (have never commented, but short version: I've done one bake on my 4850 without replacing the white paste on the memory chips - only the thermal paste on the GPU chip - and it worked great; got about an extra year out of that first bake before it flaked again; just did my second bake, and am awaiting k5 pro paste before finishing the reinstallation - so, not sure if it worked, but I'm hopeful)... thanks for keeping these updates coming. I'm interested in trying this option if I have further issues with my 4850 after bake #2.
      Wanted to chime in here to say that the behavior you're encountering is something that happened persistently with my first graphics card BEFORE I did the first bake: the machine (screen?) would become unresponsive - I could see the mouse moving around, but couldn't click or do anything; and then eventually the computer would just shut down. This resolved, for the most part, after the first bake, and while I'm not positive what was causing the unresponsiveness, I have always mentally attributed it to the GPU issues.
      In addition to changing / upgrading video cards, I've wondered this: is there any possibility of converting an old iMac with a bad graphics card so it could be a "passive" monitor for another computer? I doubt it, but have wondered. I'm going to keep my machine going as long as I can, but eventually may just cut my losses and part out whatever's worth salvaging.

      Brannon, I have experienced many different symptoms pertaining to my 4850 card through the years, but never once did the machine suddenly power off. The new symptom I experienced with my 4850 card over the past month was that the screen would go dark, however the machine was still powered on and the fans were still running. In the case of the 6970M though, the machine is definitely powered off when the problem occurs, which is something totally new. And as I said in my pinned comment, the weird part is, it only happens when my son starts to play his Roblox game for about 5 minutes, and then the power-off occurs when he switches out of full screen game mode back to Firefox. Upon switching to Firefox, the iMac immediately powers off as if the power cord was yanked. And yet my wife can do email and browse in Chome for hours without problem. So I am contemplating what to do at this point.

      @JDW-  3 года назад

      In 2009, there were EARLY and LATE models. Mine is a LATE model 27". The 6970M originally shipped in the 2011 27" iMac and requires a special triple-heat pipe heatsink that fits fine in 27" models between 2009 to 2011. The EARLY 2009 large-sized iMac was only 24". The smaller internal dimensions would not accommodate the heatsink made for the 27" model. Also, to use a smaller heatsink made for a smaller iMac on a 6970M is uncharted territory. It probably would not work well for cooling because even the larger triple heat pipe heatsink is barely enough.
      I recommend baking your stock graphics card (and then repaste it) as the cheapest way to get an old iMac working again. It's not a permanent fix, but it often lasts long enough to make the bake worthwhile. Folks who dislike baking and who dislike the 6970M often use a Windows machine to flash an old MXM Nvidia card. That is something I've never done because (1) I don't need to with my 6970M and (2) I don't own a Windows PC.

In fact, used PCs are sold so cheaply I wouldn't be surprised if you could find one costing about as much as I paid for the 6870M! Of course, the reason I bought the 6970M was to keep my 2009 iMac usable with MacOS. And so far, it's working fine.

      Thank you for your helpfulness! I've done a lot of checking online. Pretty much all the reports of people with 2011 iMacs which had a bad 6970M video card complained of some kind of on screen artifacts or lines. I get none of that. I only get sudden shutdowns. And those shutdowns only occur when I either load a 3D game or if I manipulate a 3D file in Photoshop. Temperatures at the time of the shutdown are only about 48°C on the 6970M heatsink, which is why I don't think it is a thermal issue. If it was a thermal issue, I would expect the video card to shut off, leaving me with a black screen but keeping the machine (and fans) running. But when my shutdowns occur, the entire machine suddenly powers off. And while some may contend that could be my power supply, the fact is I never had a power supply issue before. It still could be the lack of power, I suppose, but I really don't want to pay US$150 on a power supply, especially since I don't even know if that would cure the problem. Hmmm...

More specifically, you cited the green screen and failure to boot. In the case of the 6970M I recently purchased and placed in my late 2009 iMac, I never get a green screen or artifacts, and I can always reboot without problem immediately following a power-off problem. That, in combination with your own experience, tells me that the 6970M card I have is probably not bad. Instead, it appears there is some incompatibility, most likely on a firmware level.
      To test my theory about a possible "incompatibility," I decided to repaste my 6970M yesterday, using Thermal Grizzly Kryonaut on the GPU (which is about the best GPU/CPU paste on the market) and K5 Pro on the memory chips and square inductor parts. When removing the heatsink, I was unpleasantly surprised to see that one of the memory chips had no paste on it at all, and this is clearly the fault of the seller in Hong Kong, as I asked them if they repasted the card just prior to selling it to me, and they told me, "Yes."
      And so, I am testing the freshly and properly repasted card today, testing a light load first of email and light web browsing. And I will do more heavy testing this evening. After that, I will likely make a short follow-up video to share my experience with others about use of a 6970M in older 2009 iMacs.
      Now, as to your repeated bakes lasting only a rather short time, I am very sorry to hear that. It could be that baking the 6970M simply doesn't last as long as baking the 4850. But to know that, I will need more people to give their experiences about baking the 6970M to know for sure. Until now, the vast majority of comments under my Bake videos have been about the 4850 card. But one thing I do know is that when you bake and then get only a week or less of use out of that bake, the card is truly on its last legs. One person has suggested that paying a professional to remove the old GPU and properly solder in a new GPU would restore the card to new condition. However, I don't think it is worth the cost, as that person told me the cost in Europe would be about 300 Euros. I bought my 6970M card with express mail shipping for much less than that. The point is all about how to keep our old Macs alive at the lowest possible cost. And toward that end, I would certainly appreciate hearing how your latest bake fares in the coming days, weeks and (hopefully) months ahead.

      Because it is much, much cheaper to do the bake. You save a lot of money. Your total cost for the bake is (1) the cost of the thermal paste I recommend (which would not exceed US$20), (2) the cost of electricity for 10 minutes of baking (to small to calculate), and (3) the cost of your time for about 3 hours, since time is money. All said, it's cheaper than the 200 Euro you mention. However, at some point, you will no be able to re-bake your video card. In my experience, you can only bake them a limited number of times. So after that, you would need to spend more money to buy a replacement card. You could do that instead of the bake, but I recommend the bake because it's the cheapest thing you can try and it works for most people who use the paste I recommend.
      Lastly, it's important to keep in mind these iMacs we're talking about are very old. 10 years is a long time in computer years. So it doesn't make a lot of sense to spend a lot of money on them, especially when it is conceivable that something else could eventually go wrong with the machine. Logic dictates that the lowest cost fix for an old computer is often the best fix of all. That fix is the bake.

      When your 2012-14 GPU goes belly up, you are SOL. Time for either a not inexpensive tech visit or a replacement logic board. And you will need new sticky gasket for the screen. 2015 and later would be worth accepting these compromises because of the 5k screen. In the meantime I'll take my 2011, thank you.
