Thread: Q6600 overheating problem

I was surfing the fora and I thought it would be a good idea to squeeze more performance out of my Q6600. Overall my system is very stable and I am running Win 7 64 bit RTM, without using many CPU hungry applications (though getting my system to work at higher clock speeds is not a bad thing either) So, I decided to run some preliminary tests to see how my system behaves

System info:
CPU Q6600 @ stock speed (2.4GHz) G0
CPU cooler -> stock CPU cooler
Motherboard Gigabyte EP45-DS4
Case: Sharkoon Rebel 9 Value with the following fans installed:
1x 120 mm fan at the front
1x 250 mm side panel fan
1x 120 mm fan at the back side

After 13 minutes of CPU stress using Prime95 64 bit (balanced test) I had the following readings (using Real Temp and CPUID and hardware monitor):
Temperature sensor Idle 46C (114F) After load 83C (181F)
Core #1 Idle 48C (118F) After load 89C (192F)
Core #2 Idle 48C (118F) After load 89C (192F)
Core #3 Idle 45C (113F) After load 87C (188F)
Core #4 Idle 47C (116F) After load 87C (188F)
Stock fan speed Idle 1339 RPM After load 2020 RPM

I am pretty sure that I installed the stock fan properly but I didn't apply any additional thermo cream. A thing that troubles me is that although I have these massive fans in my case they didn't run any faster while my CPU was struggling to cope. (They run really silently and I can see their potential only the instant I power on my computer). I tried to make the fans run faster but I didn't find any option in the Bios nor does the motherboard return any data on their operation to monitor software I used. PS: Room Temperature is 28C

1) Should I change the stock CPU fan, is anyone else having problems?
2) How can I control the big case fans, and is this going to make any difference?

Load temps are much too high. Whenever you remove a CPU heat sink, you need to always clean off the old thermal compound and apply new stuff. The stock heat sinks that come with the 65 NM Intel CPU's are pretty good. They are generally good enough to cool the CPU at 3.0 G Hz.

if the case fans plug into the motherboard, it can control and monitor them. If they plug into the PSU, unless you add a fan controller, there's nothing that you can do except make sure they have power. In addition to making sure that the heat sink is properly mounted, I would recommend going into the BIOS and setting CPU temperature warning to 70 C. and setting the CPU fan failure warning. You can find these settings in the PC Health section of the BIOS.
