Thanks ;-) You can use Pins 4 and 6 instead of 2 and 6, that way off the shelf fans with a 2 pin plug will fit straight onto the GPIO header. Im using a little 20mm high speed fan DC 5V 0.2A which works extremely well. Although it is a little louder than a bigger fan as it rotates at a great speed.
Another cool video :) My Pi 2B came with a fan and heat sink set, but I like how you used an old fan and put to new use, creative case for it too :) looking fwd to your next Video :)
Really looking forward to seeing the follow-up with the extreme passive solutions - Great video! The more you make videos about the Rasperberry Pi 3, the more I want to get involved with it. I might get one myself, considering it's below 50€ with the B model.
Chris, interesting results, this test is important for me to see as the Pi mabe a critical part of the internet of things going forward. Thanks for all you do! Rich
I was able to setup a couple copper plates (about the size of the SoC) and applied thermal paste between each of the layers until it met with a laptop cooler (using a heat pipe, and fins that attach to a vent, which is then fitted to exit through a fan). This setup works very well indeed for over-clocking the system. It just recruited a little work to make a case which would securely hold the fan and heatsink in place with stand-offs for the pi board itself.
Good to know that you can indeed use the GPIO pins to power the fan. Very useful. Shouldn't be too hard to find a small, 5V+ fan somewhere. Perhaps I could even modify the existing case I have for my Pi, and just cut a hole for the fan to sit, and hot-glue it in place.
Professor, really loving (not a hyperbole) the DIY solution you did for the fan mounting. Now that's punk computing! Please, consider on doing more videos with DIY solutions. I'm willing to bet that with a shim of copper, some drops of thermal paste and your fan solution the Pi 3 CPU could be kept under 40, even 35 °. Looking forward your extreme cooling video.
Great video. I'm not comfortable with pi running at 80'c , and any cooling will ease my mind, especially when running the pi 24/7. However, I'm also concerned about the fan noise, so hopefully the 5v fan will be quiet enough.
I'd love to see a video where you also put a heatsink on the memory chip on the bottom and LAN chip and test out various overclocking settings with and without the fan. I know that OC support for the 3 isn't official at this point, but people have been doing it anyway for stuff like RetroPIE to get N64 emulators running smoothly.
duh? you think that's bad, it took me 40 years to realize the "When it rains it pours" Morton salt advertisement was not only about the salt not clumping up from moisture in the home, but was a play on words of the wisdom saying about things getting worse and worse, sometimes, "It never rains but it pours..." That was a super duh moment. ;-) wink wink.
Very good videos! I did your test.script with my own Pi3 v1.2 and your results are very reliable! I used a small aluminium Heatsink very similar to yours, but I milled the bottom flat and sandblasted the top. Used liquid heatglue. At an ambientetemperatur of 20°C I got the following results: 40.8 67.7 74.1 77.4 79.5 80.1 Than I added a fan and let the Pi cool down propperly, I used a Sunon MB40101V2-000U-A99 Results were: 30.6 47.2 47.8 47.2 47.2 47.2 wich is pretty silmilar to your results and shows, that your test is reproducable! Was fun to learn these things! Best Regards, Christian
LMacNeil you are right and bt the way you can buy fans for Raspberry Pi for 5 bucks and if you know how to mod stuff you can fit a mini metal cooler and a fan together
I can't believe I'm the only one having the fan (5V 20mm over the standard little heatsink) connected to the 3.3V. It's absolutely silent and doesn't seem to destabilize the PI. Tmax 57°C when stress-tested.
Using my Pi as a Media Center/Retropie Device, previously was the Pi2 which did ok in the case with a basic copper heat sink, however the Pi3 was easily approaching max temp when running Kodi visuals and some Emulators.. found a temporary fix for now but really looking for something more subtle in the long term!
I'm seeing others that are saying don't run the fan directly off the GPIO pins as it will fry the board (or stress it). One vid shows it using GPIO pins as a relay of sorts and a transistor, also programming the pi3 to turn the fan on at a certain temp.
Be clear, I am NOT running the fan from the standard GPIO pins here -- they cannot supply enough power without damaging the Pi. Here I am powering the fan from the 5V pin, which is technically not a GPIO pin. It simply taps the 5V line BEFORE it enters the Pi's voltage regulator. All other pins effectively come after the voltage regulator (to deliver very limited current at 3.3 volts), so do not run a fan from any of the GPIO output pins. As you point out, you can use an GPIO output to control a fan indirectly, but not to power it.
I really have no idea why your videos get "dislikes." These are really very good--other than that you can't seem to tell the difference between a screw and a nut, lol... ;)
The temps between the two fans are virtually identical in the grand scheme. This makes me wonder is the chip's heatsink reached it's equilibrium in regards to thermal dissipation.
Nice video i love to tinker with stuff myself, I've always wanted a pi but they've been to underpowered until now. I was thinking of buying one for kodi in my bedroom, i have a shield tv for kodi in my living room.
I love the DIY! But I'm not sure you cooled the CPU heatsink as efficiently as you could have. It looks like the central cylinder that houses the fan bearings was right above the heatsink. I wonder if this would create a deadzone of minimal air movement directly under the centre of the fan? Actively cooled heatsinks move air across the heatsink, however given the large deadzone of the fan coupled with the tiny heatsink means that any cooling effect is dramatically reduced I think? I'd be curious what happens if you move the fan off-centre a bit to see if that makes a difference. That said, great video. I enjoyed watching it :)
You made the "bracket" a lil more complicated than it had to be. Withall those CPU fans/heatsinks just "laying around", I would have just scavanged up some MoBo standoffs. You can join as many as you like together to get the "height" you want from the bracket system. Another awesome side effect of this is that Screws can just go right into the end of the top standoff....... just sayin :)
Would be cool if you could the same test with a smaller fan, like _"Axial Fan, Brushless Motor, Tubeaxial, Vapo, 5 VDC, 20 mm, 10 mm, 1.5 cu.ft/min, 0.042 m³/min"_ from Element14.
I've enjoyed these Pi-cooling vids but I do need to correct your terminology. The long, threaded items are either screws or bolts, while the small hexagons that wind onto the bolts (or screws) are called nuts. You got the washers in the right place :)
I would say there would be very little CFM near the heatsink, the majority of the air pressure would be dissipating radially. With such a small heatsink you'd want the blades to be pushing air directly into the top (off-centre). You'd definitely be cooling the surrounding PCB though, which certainly counts :D
+Zach Davis Thanks for your kind feedback. For some purposes -- such as basic office work, e-mail, etc -- single board computers can already compete. Checkout my "Raspberry Pi as Only PC" video. :)
+cake5000 I am heading in the "extreme overclocking video" direction! :) I need first to figure otu a good means of connecting a better heatsink (and maybe heat pipe) to the Pi's SoC. :)
thanks for the video. you always have good information on technical things. but do you have a video on auto active fan setup with raspberry pi, that auto run from the temperature of the pi?? thanks
Those things that you keep referring to as bolts are actually called nuts! The part with the long thread and the screwdriver slot is the bolt or screw.
A prime example of when a 3d printer would have come in handy or at least a less butchered job on the Acrylic because it is blocking a lot of airflow from the fan. Oh, another thing to consider is placement because the the larger the fan the more the center hub (dead air) is taking up more room over the CPU. Off center that fan and the temps would be lower due to more air flowing through the heatsink.
+Dark Alchemist So true, a 3D printer would be so handy here. :) Note that the fan is not centered over the CPU -- it is significantly off-centre, as the CPU is not central on the board.
ExplainingComputers Ahhh, I couldn't tell as the CPU is so small it looked like the fan was directly over it though some air flow was being blocked due to that hole in the Acrylic/Perspex not really being round. I still find it interesting how around version 5 or 6 of the Pi it will be able to do everything my big PC does at least as well. Miniaturization though it will soon hit the brick wall as Intel and AMD have due to the limits of Silicon. We have to get something else or are we always doomed to a max of about 4-6ghz? Doesn't matter if there were 1 million cores in these things, or regular computers, they have all hit that wall and can't give us any more speed. Main reason I only upgrade my PC now once every 6-8 years when I used to do it every two.
+Dark Alchemist All so true. :) I keep thing that I edit videos on an 7 year old PC, but is still works fine (although it has several different graphics cards and drives in that time).
ExplainingComputers Exactly, and the same for me. My 7.5 year Dual core is finally dieing or I wouldn't even upgrade though I just made my 72 year old mother an AMD based pc on an A8 and all tests I performed on this machine and it that thing was as fast (single core processing) and everything else it blew it away. So, that helped to reinforce the need of a new PC but I figure the modern Intel next to the top will be fine for another 7-8 years. This system saw two video cards and IDE then SATA then SSD over its lifetime. Ironic everything is advancing around the main component being the CPU, lol.
***** You can see why the PC market is in so much trouble. After decades of constantly selling us new stuff, they have finally started selling us systems (or parts for systems) that work well for a long time. In other words, their product is now so good that, ironically, we will be buying far less of it. I am currently running a 3GHz Core 2 Quad. Probably the best system I've ever used, even though I know an i7 would be faster.
You should design a bracket with a 3d printer that allows you to clip said bracket into the pcb screwholes. This bracket would allow you to clip the pentium fan on, since it kinda looks like it was "designed for the raspberry pi"

Amazing DIY skills! The whole idea for the base and the plastic for the fan are such great ideas.
Chances are, that fan draws more power than the Raspberry Pi itself.
+Joshyy Indeed! :)
Can this harm the PI?
+Zynoz of course not.
+Takuya Kousaka ok
Thank you for the quick answer :D
I did look it up the other day and found that they are making fans specifically for the Pi now.
Cant stop watch your incredible good videos looking forward for next.
Thanks. :)
I also wish you the best as you're nearing 100k subs. Been watching you for a while. Keep up the good vids!
Great videos. Your work inspired me to start working on quadracopter project base on PI3
Thanks ;-)
You can use Pins 4 and 6 instead of 2 and 6, that way off the shelf fans with a 2 pin plug will fit straight onto the GPIO header.
Im using a little 20mm high speed fan DC 5V 0.2A which works extremely well. Although it is a little louder than a bigger fan as it rotates at a great speed.
Yeah hartoz, I use pins 4 & 6 with a high speed fan too. Great tip ;-)
I don't know if dies it deliberately but he's funny I enjoy watching him, making it easier learning about computers.
"does" not "dies"
Can't wait for the extreme passive cooling!
0:50 !!! Zalman CNPS9700 on the left there! Great CPU cooler! I've had mine for almost ten years!
those things never die lol, i still have a stock intel 2004 125w cooler from a "preshot" it works extremely nice on my 65w cpu
I'm new in Raspberry´s world and your videos help me a lot!!! thanks
Another cool video :) My Pi 2B came with a fan and heat sink set, but I like how you used an old fan and put to new use, creative case for it too :) looking fwd to your next Video :)
Genius idea with the soap tube
Very good video, the fan have the best airflow and noise balance is important.
Really looking forward to seeing the follow-up with the extreme passive solutions - Great video!
The more you make videos about the Rasperberry Pi 3, the more I want to get involved with it. I might get one myself, considering it's below 50€ with the B model.
Hats off to ur talent, salute
This is like a Blue Peter episode on how to make a Pi cooler :P
+Deltaexio I was half expecting the one he made earlier too........ :)
ZPower Gaming I deleted it, don't worry.
nice video
cant wait to see the extreme passive cooling!
I like the little fan case construction :)
+DynamicHunter It surprised me how well it came out! :) Sometimes things just work.
My favourite channel :D keep up the good work !
Chris, interesting results, this test is important for me to see as the Pi mabe a critical part of the internet of things going forward.
Thanks for all you do!
Rich
Very useful- thanks. Saves a lot of experimentation
That IDE adapter/power supply is really cool. I need one, or a half dozen, of those.
+John Ratko It remains an extremely useful piece of kit on all manner of occasions! :)
I was able to setup a couple copper plates (about the size of the SoC) and applied thermal paste between each of the layers until it met with a laptop cooler (using a heat pipe, and fins that attach to a vent, which is then fitted to exit through a fan).

+Zepher Tensho A hole and hot-glue sounds like a good solution to me! :)
Love your creative solutions.

i think it looks well nifty! great video.

digging that new intro
Congrats dude great job :)

u should try overclocking with this
+Gaming Ace Yes, I must try that! :)

I just realised what colon, dash, end paranthesis mean. It's a smiley face turned sideways! I could never figure that one out until just now, duh!

Nice case around your PI so have a PIE and enjoy your PI with some Multimedia..thanks for the knowledge..:)

All my old Pentium CPU fans were 12v but luckily I was able to find a 30mm 5v fan at my local parts store
Awesome :) great tests thanks.
Brilliant work.

As you point out, you can use an GPIO output to control a fan indirectly, but not to power it.
Nice results... just wish they had a pre made case/fan combo rather than DIY but I guess I'll have to grab a 5v fan and try it out!
+LJH08Ralith I would imagine that demand will soon create supply!
Glad to see your 2nd fan was off center. Think there may be a dead zone directly under the hub. Wondering if that would make a difference?
I really have no idea why your videos get "dislikes." These are really very good--other than that you can't seem to tell the difference between a screw and a nut, lol...
;)
My brain ceases up when talking on camera on occasion! :)
Mine too. No worries--great channel. I've definitely subscribed.
outstanding.
In the future you should do tests with the PI in an enclosure to see if there is an impact in temperature as well.
un capo! que buen video! felitaciones!
What about using USB driven fan with goose neck. You can bend it towards the heat sink. It won't require any additional power connections.
Great video!
Very nice video
Prompted by last your video I had a look around for cases that act as heat sinks. A company called Flirc make one.
The temps between the two fans are virtually identical in the grand scheme. This makes me wonder is the chip's heatsink reached it's equilibrium in regards to thermal dissipation.
You are almost certainly correct. :)
Nice video i love to tinker with stuff myself, I've always wanted a pi but they've been to underpowered until now. I was thinking of buying one for kodi in my bedroom, i have a shield tv for kodi in my living room.
wow this channel feels like I'm learning about computers in the 80s, I should probably subscribe
+hornylink You should definately subscribe! :)
great tutorial thanks man!
I have never seen quite a mess of heatsinks and fans before...
great video, thanks

That said, great video. I enjoyed watching it :)
+Konrad Strachan The centre of the fan was offset. :)
Maybe you should think about adding a little flue for passive cooling.
Awesome video :D
A fan on a pi? Cool!
You made the "bracket" a lil more complicated than it had to be. Withall those CPU fans/heatsinks just "laying around", I would have just scavanged up some MoBo standoffs. You can join as many as you like together to get the "height" you want from the bracket system. Another awesome side effect of this is that Screws can just go right into the end of the top standoff....... just sayin :)
Great to see you modding the Pi! Is there anyway it can be used as a control for a NAS setup? Love your sense of humour btw :)
Would be cool if you could the same test with a smaller fan, like _"Axial Fan, Brushless Motor, Tubeaxial, Vapo, 5 VDC, 20 mm, 10 mm, 1.5 cu.ft/min, 0.042 m³/min"_ from Element14.
oh man that's a huge fan. They make 1 inch fans. Or 2.5cm.
Good video. Thank you.
I've enjoyed these Pi-cooling vids but I do need to correct your terminology.
The long, threaded items are either screws or bolts, while the small hexagons that wind onto the bolts (or screws) are called nuts. You got the washers in the right place :)
+brando6BL Correct in the next video. When filming macro shots under movie lights, you sometimes do not say the right words . . .
Fair enough, and I noted that in the 3rd vid. That sounded more professional, and the results re. the copper and the finned hs really topped it off.
I would say there would be very little CFM near the heatsink, the majority of the air pressure would be dissipating radially. With such a small heatsink you'd want the blades to be pushing air directly into the top (off-centre). You'd definitely be cooling the surrounding PCB though, which certainly counts :D
+samthepoor The fan is not centred on the heat sink, so the latter gets good airflow (the SoC is not in the middle of the Pi's PCB).
+ExplainingComputers Aha, right you are, apologies!
+samthepoor No problem. :)
1:01 "Fit a Pi 3 on this Cooler." ;D
You should try to make a small container on top of the heatsink and put water in it and you'll have a water-cooling system :P
For even more extreme cooling, try oil immersion.
Great video I love your pi videos do you think that single board computers will ever be able to compete with regular pc's or even a small NUC build.
+Zach Davis Thanks for your kind feedback. For some purposes -- such as basic office work, e-mail, etc -- single board computers can already compete. Checkout my "Raspberry Pi as Only PC" video. :)
I only wished you used a heatpipe from an old laptop or a better heatsink.... Would love to see an extreme overclocking raspberry pi video.
+cake5000 I am heading in the "extreme overclocking video" direction! :) I need first to figure otu a good means of connecting a better heatsink (and maybe heat pipe) to the Pi's SoC. :)
thanks for the video. you always have good information on technical things. but do you have a video on auto active fan setup with raspberry pi, that auto run from the temperature of the pi??
thanks
Could you do a test comparison of active cooling with and without a heat sink?
This was posted a day after my 15th birthday...
I want a super small water-cooled pi!
Impressive !
You use dir instead of ls?
ls is good because it changes the colour of files depending on their type
Those things that you keep referring to as bolts are actually called nuts! The part with the long thread and the screwdriver slot is the bolt or screw.
+martin nash I know, I know. But under the movie lights, my brain sometimes gets scrambled. :(

Maybe you could have guided the air under the fan more directly to the heat sink and got even lower temp?!
AllWinner's chip really need cooling fans. Especially when no voltage control chip.
Pretty sure the white connector on that molex adapter is only 7V.
You should design a bracket with a 3d printer that allows you to clip said bracket into the pcb screwholes.
This bracket would allow you to clip the pentium fan on, since it kinda looks like it was "designed for the raspberry pi"
+Garpenlov Yes, there is a great opportunity for a 3D printed bracket here.
white connector on the fan molex splitter is 5 volt
i have used pi 3 with original PSU at 5v 2.5amp and could have my 500GB 2.5" hdd external drive working.MY 2TB 3.5" external hdd working
Great videos, very easy to follow.
I was wondering, if I have a 5v usb LED strip, could I run it of the gpio's?
They are usually called "nuts" :)
My mind often does blank when recording -- so many things going on!
@@ExplainingComputers you do an amazing job Sir. Hats off to you and your work, and the sharing. Gratitude 🙏
Lol...I have my Pi case open and a small desk fan which I turn on when the temp sign ligts up on my screen...Will have to try this
