hear is the deal, when i start my pc the fan runs, then i get cpu fan error and it stops, so i unplug the cpu fan and try again, still get cpu fan error but the fan keeps working. idk what the problem is, to me it just sounds like a poor connections but would like someone else's opinions (btw i just got new mobo and cpu for my computer so they should be fine.) i have never used the stock cpu cooler and heatsink as when i got the mobo i right away installed my after market cpu cooler, i cant tell you if this was a issue with my old mobo because it was not compatible so i had to wait to get a new mobo to use it. the cooler is the alpine 64 pro

Thanks in advance!

Got to bios and check the pc health (or whatever it is called) page. The minimum rpm setting for the cpu fan might be to high for your model.

Is it a 3 pin or 4 pin? Are you connecting it to the cpu_fan pins or the sys_fan pins? What happens if you go into BIOS first, does the fan work fine? What do you mean by fan error.....you get an actual message, or a beeping sound - or you visually notice that the fan doesn't spin?

I expect it stops and then you get the cpu fan error.

You know the questions I asked actually matter, so please answer them. 3 pin or 4 pin, what is the error message - in Windows, or do you have a motherboard numerical error panel? You should definitely go into BIOS and under "system health" or something like that, where you can view the temps, you should see what's going on. What is your mobo....what is the fan model? Come on for diagnostics we need at least the essentials.

Here is somthing maybe very important to the issue, so today i thought i would try to troubleshoot some of my devices to see if they are the problem, so i umplugged my mouse and keyboard, bam no problem. now i want there to work together because i dont want to unplug and replug every time, i dont want to get new mouse and keyboard because mine are expensive t-t
