New System build running hot, need advice!

Hey Everyone -
I've got some great advice from the people on this forum before and I hope you guys can help me again!

I recently put together a new system and I believe that it is running far too hot for what it should/could be. I could really use some advice as to if I should upgrade my cooling or if you think any of the parts might be defective.

I was hoping to overclock this system slightly, but I feel as if it is already running too hot.
I know my case isn't exactly the best of the situation, but I really like the look of it and how quite it sounds even with my fans running at high. Any advice is appreciated though!


The computer is:

Intel Q6600 Quad core - not overclocked, running stock cpu cooler/heatsink and stock thermal paste. B3 Stepping.


Antec Sonata III Case - Rear and front 120MM fans installed (antec tricool)

Antec Earthwatts 500 watt PSU

ASUS P5K Premium WIFI-AP ATX LGA775 P35 2PCI-E16 2PCI-E1 3PCI SATA RAID Sound WLAN 1394 Motherboard

OCZ Reaper Hpc Edition PC2-6400 DDR2 2GB 2X1GB DDR2-800 CL4-4-4-15-1T Dual Channel

EVGA E-GEFORCE 8800GTS Superclocked 576MHZ 320MB 1.7GHZ GDDR3 PCI-E Dual DVI-I HDTV HDCP Video Card

WD Raptor 74 gig HD, and WD Caviar 500 GIG hard drive.


Anyway, down to the numbers.
Right now, in a cold basement, Everest and Speedfan are telling me that the CPU is running at 44C, with the individual cores ranging between 52C and 56C.
GPU at 53C

When I put the processor under load by playing a game the processor reaches temperatures of 65+C and the individual cores are reading 75C-80C. This is kind of worrying me.

I don't know if this is normal or not, but I would love any suggestions as to better ways to cool this system. Or if anyone knows any bios tweeks to get similar performance with less heat please let me know.
Thanks in advance!

Well, your Graphics card is running perfectly fine at 53 Celsius idle. As for your CPU, I think that's pretty normal for a Quad Core on stock. I may be wrong though.

I agree with Bloodred. But you could also look into getting a better heatsink for the cpu. Something like a Thermalright Ultra-120 Extreme, or a Scythe Infinity should work quite well. Or if you want you can step and go with liquid cooling and lower your cpu temps much closer to ambient air temps.

Those load temps are way too hot for stock. You should reseat your cooler or, better, get a good after market cooler.

Thansk for the advice guys, I wasn't really too worried about the graphics card. Its got a lifetime warranty anyway so if it blows..I just get a new one.

However, the CPU does concern me.

I've built a few computers, but never installed an aftermarket cpu cooler.
I've heard of a few different good ones. Can anyone reccomend one that is effective, but relativly easy to install?
Also, will I need to apply new thermal paste with a new heat sync? I have some OCZ silver paste from about a year ago, but I'm not sure how long this stuff keeps for.
If I need new paste, can you guys make a reccomendation too?

Thanks so much for your replies so far

Well for good thermal paste it is hard to beat Arctic Silver 5 or Arctic Ceramique. As of an easy to install after market heatsink I think you need to look at heatsinks from Scyhte, Thermalright, and Zalman. It just depends on what you consider easy to install.
