CPU temperature too high but fan not running at max speed

coolingcpufantemperature

I think I am having some problem with processor fan… it never runs on full speed event though my processor temperature is going so high. I am using HWMonitor (also speedfan) to record temperatures and my temperature readings in normal are as follows:

Intel Core 2 Quad Q2800:
Core # 0: 65 c
Core # 1: 60 c
Core # 2: 59 c
Core # 3: 59 c

But during high usage like while playing a game or something it hits around 80+, I tried cleaning the grill and fan and putting new thermal grease but didn’t help.

HWMonitor further says:

FANS PWM: 
FANSWMIN0: 50%

And from the above reading I am guessing that my fan is running on 50% always and I think it is because it looks slow… Not really making any sound and you can feel any air blowing out of it if you put your hand in front of it..

I tried speedfan by my motherboard isn’t supported…
By BIOS also doesn’t have any such option all it has is:

Advanced > Fan Control
- Processor Zone Response - Normal
- Processor Zone Damping – High
- Auto Fan Detection – Disable
- Fan Detection Error- Enable

My Specs are as follows:

Motherboard: Intel DG43NB [Version AAE34877-402]
CPU:  Intel(R) Core(TM) 2 Quad CPU Q8200 @ 2.33GHz [Socket 775 LGA]

Now I really want to know how to take my CPU temperature to normal again probably by making my fan to run at max speed, please help?
Thank you. 🙂

Just checked processor specification here: Intel
And it says for Intel® Core™2 Quad Processor Q8200:

TCASE 71.4°C

Am not sure about the usage of tcase, but prbbly i cld help in solving the issues.

Best Answer

Control Panel -> Power Options -> Edit Plan Settings -> Change Advanced Power Settings -> Processor Power Management -> System cooling policy -> Active

This is about the only system controlled method to control the fan speed / processor load mannerisms.

Alternatively, for more control, you would have to update your BIOS as suggested by @ZianChoy and attempt to control fan speed using SpeedFan.

You should also be able to control Fan Speed via the BIOS even prior to updating it, some BIOS interfaces let you configure rules, fixed RPM, or Modes whereby you could select High Performance making your PC slightly louder but effectively cooler.
