PWM Fans & Temps

Hi,

I recently built a new PC based on the Q6600 G0 CPU and wanted to make it as quiet as possible as I suffer from sound sensitivity.

I decided to use PWM fans as they will power on and off as and when they need to. My CPU is at stock speeds and I am not bothered about overclocking.

The front and rear fans don't cut in until the CPU is around 43c and the PC will idle at around 43-46c.

If I play games the temp goes up to around 55c and I have ran stress tests for an hour and the temps reach 58-62c max.

Can you please tell me if these temps are safe?


Thanks for your help.
 
Depending on your motherboard you can adjust the temperatures the fans kick in at. Gigabyte have the most 4-pin headers per motherboard of any of the manufacturers, but only Abit & J&W give you ramp-up tables that make these headers truly useful. Look in your BIOS to see what adjustment is available.

I would say the temperatures look fine, but system instability is always the enemy, not a number on a display.
 
Thanks for your help.

It is a Gigabyte motherboard that has two 4 pin headers. One for the CPU and one for the system fan.

I am using the Artic Cooling PWM fans that can have up to five daisy chained. The CPU is on it's own header and the two case fans are daisy chained on the second.

The only settings for the fans I have in the bios are Auto, Voltage and PWM. It's currently set to auto which gives the same result as PWM.

I'm guessing Gigabyte motherboards would know when to cut the fans on and off and what is safe as the fans do run faster the hotter the PC gets.

The PC seems stable but I had one blue screen which happened during a windows update. Since then it has been running fine with no problems.
 
I wouldn't worry about those temperatures, they are very much within safe levels. If the computer is showing to be stable, and your comfortable with how the temperatures are then I'd say you're all set. Sometimes I get really paranoid at my PC temperatures when they get a bit too high, even regardless if other people say they are fine, so just make sure you're happy with them :)

Also I wouldn't worry about that BSOD, it was probably just a one-off caused by Windows Update.
 
Hi,

Thanks for your help.

It seems stable and has been running for the past couple of days with no problems. Like you say I think the BSOD on windows update was also a one off as it hasn't happened since.

I have now bungee modded my HDD and everthing is even more quieter. The only problem is that I can now hear my graphics card fan speed up when I gaming :p
 
I got my pwm to 105C before my computer shut down :eek:

Now I run a fan on them and keep them at 60c when running at 3.8Ghz and above.
