On Saturday I replaced the motherboard of my computer because my old motherboard wasn't working anymore. Everything went well, and after some tries my PC was booting and working! I noticed the CPU fan was making a lot of noise. I downloaded cpuid hwmonitor. The CPU was in idle state at 50 - 60 degrees Celsius. And the CPU fan was running at 6700 RPM!
After reapplying thermal paste two times (first time the pea method, then the card method, and then again), the CPU is still hot, but not that hot. If my PC isn't doing anything, my CPU is around 30 - 40 degrees Celsius. But it is getting hot very fast. And the CPU fan runs about 4000 RPM. When I start a program, the fan goes to 6000 RPM.
I downloaded and installed speedfan to try and change the CPU fan's speed. I can see the temperature of my CPU and I can see how fast the fan is going. This fan isn't noted as "CPU fan" or something but as Fan 1
. The fans are listed like this:
Fan 1: 0 RPM
Fan 2: 0 RPM
Fan 3: 0 RPM
Fan 1: 3500 RPM
Fan 2: 0 RPM
Fan 3: 0 RPM
Fan 4: 0 RPM
Fan 5: 0 RPM
GPU Fan: 1400 RPM
Why all those fans? I have only three fans (CPU, GPU, Power). In speedfan I can control only the GPU fan. And all the others aren't doing anything when I change their values.
My question:
How can I make my CPU cooler and make my CPU fan make less noise and RPMs (my computer is clear of dust)? It would also be nice to know why speedfan isn't working.
Hardware:
- Motherboard: Gigabyte GA-970A-UD3 Rev 1.1
- CPU: AMD FX-8120
- CPU Fan: Stock AMD fan
- GPU: AMD Radeon HD 6850
OS
- Windows 7
Note: I turned off Smart Fan for speedfan.
Edit: I fixed my problem. I had to replace my amd stock fan with a better one. I bought this one:
