Dell Optiplex Fan Fix Complete Walkthrough - GX620 760 780 SFF

- In this video I walk you through taking apart and turning the cpu fan around so your computer stays cooler. This will work on most Dell Optiplex SFF small form factor desktop computers. Including GX620 which is what I used in this video. The 760 745 780 also look to be the same with maybe subtle differences.

Thanks man, now i can replace that
No problem 👍
Thanks for the video
Mine had all 4 rubber holders for the fan broken. So the fan was not being held by anything and it was making A LOT of noise. Good thing that I had 2 other GX620 laying around for parts. One of them had 2 rubbers ok and the other one had all 4. I also opened the fan sticker and applied some Singer Oil into the cooler. Be careful not to put too much oil and try not to let oil get on the outside plastic, where the sticker will be reapplied. Also, be careful not to get the sticker glue dirty, so you can put it back in place (and hold the oil inside). I did not reverse the fan, I think it works better the way it is and you also get positive pressure inside the case (which is good for a number of reasons).
The CPU fan is supposed to be blowing through the cooler, not the other way around. While your workaround may lead to less dust buildup, the CPU & rest of the PC will run hotter. Maybe a good idea to somehow attach a rear fan to the outside of the rear of the computer to pull out air instead. BTW, I replaced my fan with a Noctua NF-A9 PWM fan, there's adapters for sale on eBay to convert Dell connectors to work with retail fans. One of the connectors is a dummy, Dell engineers thinks consumers are stupid, many of us can upgrade the fan to one with a higher output (more RPM) for better cooling.
Hey Charles, I did the same with the housing fan (not CPU) on my Optiplex 8300 sff but now I get an Error when I start up. The Noctua fan is working fine but I think it has a lower RPM so the BIOS thinks it's faulty. Did you encounter the same issue and found a work around?
Is thst the same procedure for the 780 optiplex
I believe he is wrong. This is maybe a short term solution, but will fail miserably in the long run. I cannot believe nobody else has commented, but the fan was the correct way to begin. The CPU needs to stay cool the most. Unfortunately, cooling for this system overall is lacking, flipping the fan is not the solution. Keeping it clean the the best thing you can do. I cannot disagree with him though, maybe they are engineered to fail. If your CPU is too hot, pulling hot air into the heat sink, not cooling... then your CPU throttles (CPU slows down) and the vents can get clogged the other way just as easily and cause the components to overheat and the capacitors to go bad just the same as in this video. Also, this PC is very old in the image, and no matter how good the cooling is, these capacitors could have gone bad along with a batch of bad capacitors that plagued PCs in this generation, not only Dell's. You can google this information, I will not go into details. I do NOT recommend flipping the front fan! This will also cause dust to be sucked in from the back vents and as I mentioned can only fail miserably in the long run. Edit: Higher temperatures obviously do not help the capacitors, and can cause them to fail pre-maturely, like in this video. Again, best solution was to keep the vents cleared out.
This total Chad wants to keep his hard drive cool, idk why... But. Let him fry a CPU and figure things out
Are the CPU, hard drive and memory temperatures lower now ?
Soooo, the question that comes to my mind is this: if reversing that fan flow was the best solution for this computer, would not the Dell Engineers have done it that way to begin with? It seems you might be giving the MB better cooling at the cost of less cooling to the CPU. I'm not sure which is the hottest running component, but am thinking it might be the CPU . . . . ?
Maybe they engineer it to fail

Yeah, this is documented as making these systems run hotter. He doesn't even notice the fan under the HDD either.
Gud
Very informative video. I have two 760 need fan replacements. thank you very much!!!
Just one question: where did you buy those replacement fans?
I had them laying around. Try ebay.
Hi did you change thermal paste on CPU in this video? just want to repair my old computer that is lying around my house.
Yes, always try to change it when you take it apart.
Nice work---
thanks
Hello. I have an Optiplex 7010 but intake fan died. Need to replace it but can't find the original fan. So want to get a 80x80 fan instead (noctua orso...). Do you have the pinout from the original cooler. Yellow/Red/Black/Blue , so i can solder on the new one. 3 pin probably. Thanks in advance.
I will check tonight for you.
My optiplex desktop makes a vibrational noise. What is it? Brand new!
it's a lemon
Same way I clean this optiplex380 after that pc not working at all monitor completely blank screen
Cool
This Motherboard broken capacitor... I see in your vídeo.... You need fix... This problem in your vídeo.... In Brazil us fixes Motherboard tks
Yea we fix them sometimes but these are ready for the trash heap now.
My cpu light flashes
I need to replace stock fan with a much quieter, is way too loud.
well be careful when replacing as the wiring for a fan not made for a dell might have a different wiring setup.
Dell is non standard.
Fix It Yourself! Do you have any videos how to do so, I need a quiet fan, any recommendations
I'll see what I can find out for you.
I don't have any other video yet for this.
But I do have a couple dells to work on.
If it is loud, the rubber things that hold the fan are probably broken and the fan is not being held by anything. Mine was like that and it was making a lot of noise. I was lucky to have a spare GX620 to get the parts, then it became pretty quiet, even when using 100% CPU.
