EMERGENCY: CPU Fan at a constant 2300 RPM

Wap · Jul 24, 2014

Lately my CPU fan has been racing to higher and higher RMP's when I do the simplest of tasks. Now it has reached a point where I had to monitor it, it's at 2200-2300 RPM! Help me! I was told something about a BIOS setting that is causing this but I'm not sure how to control this as I'm using windows 8! PLEASE HELP!

EDIT: Temp is only ranging from 30-45C!!!!

Sometimes dust can freak out the fan and make the RPM's go higher in order to get more air pushed it. If the inside of your case is clean, consider getting a larger fan for the heatink. Smaller fans are, well, small and have to push out higher RPM's to keep up with the heat being produced. Tha's why they spin faster and are noisier. Try upgrading to a 120mm.

But it just started doing this, and whenever I click something it gets faster and faster. I clean my computer frequently, no dust gets inside that thing without me blocking its path. It's something wrong with my CPU or maybe the BIOS Fan settings, I'm just not sure how to fix this!

What cpu, what fan?
The stock AMD cooler ranges up to 5300 RPM for example.

AMD FX-8350 eight core processor, the fan I'm not sure. It has no tags, it's just solid black roughly 90mm I think.

It came with the CPU and computer itself, it fits the heatsink perfectly.

Did it come with the 8350?
Since its not labeled and is ~80mm that leads me to believe its the stock cooler.

EDIT: That should be the stock cooler, in which case your speeds are actually quite low.

The CPU and Fan were included in the computer, I have upgraded the computer 8 months ago but only the PSU and GPU. This started happening now.

The thermal paste on it is likely degrading then.
If you can buy and reapply some such as Arctic MX-4, and reapply it to see if that helps fan speeds. If it dosent you may want to look into a new cooler.

I actually just bought some thermal paste online thinking I'd need it, plus I was going to change it sooner. Is there anything I should look out for in the mean time? My CPU temp isn't high at all, the fan is just really going at it. Are there any really main concerns or could I keep using my computer?

Gam3r01 · Jul 24, 2014

Your only concern would be temps increasing.
Just keep an eye on them, there shouldnt be anything to worry about however. FX processors can get up to low 60s before requiring worry.
The fan speeds might speed up as time goes on to keep temps steady.

Alrighty then, thanks alot Gam3r01. I will soon replace the thermal paste and get back to choosing a solution. Cheers!

Wap :

Yeah, honestly stock everything is lacking for AMD. The thermal paste was crap during the first few weeks and the stock fan is pretty weak too.

Wap · Jul 30, 2014

Hey guys, sorry for the wait. I just replaced the thermal paste from some crappy stock one to Arctic MX-4 and the problem is still occurring. What else could be the issue here? My temps are no where close to high!

SlayZombi · Jul 30, 2014

Wap :

Ok, if thermal paste is not the problem, then the real problem is the cooler. You need a good cooler, with more fins to cool, and a bigger 120mm fan. Have an extra $30? This WILL solve your problem, I garrentee it.

Depending on your temps and motherboard you can just turn down the fan RPM while still maintaining acceptable temps.
I would recommend an aftermarket cooler however, the stock one is bad all around.

SlayZombi :

How do I know if this would fit inside my case or just in the cooler screws? Mine has 4 screws making a rectangle, would this fit?

SlayZombi :

My uncle is a Computer guy and he had a 120mm fan almost exactly like the one you sent me (Not a stock fan). He gave it to me and the RPM has slowed down with a temp of 41C while playing games and 25C Idle. Thanks for the solution to my issue, it was very much appreciated.
