My CPU fan is moving too slowly

guymarshall · Jul 1, 2015

I am new to the whole PC world, and I have heard of software called SpeedFan. My CPU is too hot (about 45 degrees) at idle and I was wondering what I could do in the software (and how to do it) to get it to run cooler. My cooler is absolutely silent so it won't hurt to turn it up a bit.

What is your CPU? Is it the stock CPU cooler?

TheDualshock :

It is the stock cooler on an AMD FX 8350.

The CPU cooler is controlled via PWM. You could go into your BIOS and set the CPU_Fan mode to high performance or something. The stock cooler isn't all that great either. What are your temperatures under load?

TheDualshock :

When I start to put the CPU under load, the fan ramps up to a much higher speed and keeps the temperature under 50 degrees, but anything under that and the fan simply doesn't spin.

guymarshall :

Question, why would it hurt to have a quieter CPU at idle? 45C for idle is kinda high but if it's under 50C at load, there shouldn't be any issue. You have a good amount of room before the CPU starts throttling.

My CPU has locked itself at 1.4 GHz for some reason... What kind of temperature can the CPU get to before damage starts being done to it? I mean what temperature is ok for the CPU to be at all day?

guymarshall :

If not mistaken, it's recommended to stay below 62C with FX CPUs. As for the 1.4Ghz speed, it could be some BIOS power saving features.

Ok thanks mate. I checked for amd coolnquiet and it was set to auto, should I disable it?

TheDualshock · Jul 1, 2015

guymarshall :

Unless you are overclocking, I don't see the need to disable it.

guymarshall · Jul 1, 2015

Ok, do you know how I could get the clock speed back up to 4 GHz?

TheDualshock · Jul 1, 2015

guymarshall :

Try playing a game or something that will stress the CPU to see if the CPU clock speed goes back up. Use CPU-Z to check the speed.

guymarshall · Jul 1, 2015

It went to 1.459 but stopped there. After I quit the game it stayed at 1.4.

TheDualshock · Jul 1, 2015

guymarshall :

Try restoring optimized BIOS defaults to see if that changes anything.

guymarshall · Jul 2, 2015

Do I have to remove the battery to do that?

guymarshall · Jul 2, 2015

I just replaced the battery and changed the fan speeds and now it is slightly cooler

thanks

guymarshall :

When you enter the BIOS, there should be a keyboard button that will Load Optimized Defaults.

I'm going to buy a Dark Rock Pro3 from Be Quiet because this stock cooler, although it is quiet, it is rubbish at cooling and cannot be controlled.
