CPU fans not working, but Computer running perfectly

[rustyboy1992]

Hi,

I currently have an issue with all my CPU fans not working. There is no initial fan spinning or any sort of sounds that indicate that the fans start but then stop. So its quite safe to say that they are not working at all. I used to have this issue previously, and realized that my CPU case had a fan switch which I could use to push from minus to plus, and that would somehow turn on the fans.

However, after a PSU problem which prevented my computer from starting, I brought it in to the shop to replace the PSU. Everything was still alright after the repair but a while later (few days / 1-2 weeks?), the fans suddenly stopped working. I do not want to bring my entire PC tower all the way back to the shop just to fix a few loose cables or something really simple which can be done DIY.

So I was hoping that you guys can help me with this issue. I opened up my CPU case to check if any of the wires were loose but I'm not really sure what to look out for. I can take some photos of the inside to help facilitate the resolution of this.

if the cooling for the cpu are broken, you need to replace it. If you keep the pc running and the cpu gets to hot, you might damage it.
When you say "CPU FANS, do you mean the cooling fan for the processor? or the cooling for the entire case?
Its 2 different things.

Check the fan swith, you mentioned, again..

Sorry for the misunderstanding. I meant the cooling fans for the entire case. Basically, the AF140 and AF120 fans that are at the top, front and side of the PC casing. Yes, I've checked the switch, pushed it back and forth with no results.
