High Temps with Pentium 630...

[Colonel_Pwnage]

Before I went ripping my mobo and cards out of my case I wanted to drop this question on you guys to get a second or third opinion. My setup is an Asus P5P800 motherboard, Pentium 4 630 CPU, and a Thermaltake Silent 775 CL-P0092 for cooling. I applied Thermaltake Arcticsilver's Ciramique thermal compound to the cpu. I have the CPU overclocked from 3.0 ghz to 3.45, no voltage change so its running on stock vcore. After about a month of running it this way (plenty of time for the setting-in period to have come and gone) I'm getting 63-65 degrees celcius readout using Asus Probe while running a Prime95 torture test (Max Heat Setting). I'm seeing peeps who have overclocked this proc over 1ghz more and not temps as high as mine, whats the deal? Are these temps too high for this setup? Is the thermal compound or heatsink or both garbage? Any suggestions or info would be greatly appreciated.

That heatsink is not the best. If you want a decent overclock, you need to invest in better cooling. Check out the Thermalright XP-90 heatsink (you'll need the LGA775 adapter too). Thermaltake is mediocre, but Thermalright is excellent. Might want to change to a more powerful CPU fan and do a few things to improve case cooling first though. Maybe you can get your current system running cooler. Look at the links in my signature for a few cooling ideas.

/agree batboy,

I was having same issues (with stock HSF tho)....still maxed out temps around 65c running torture test as well as heavy gaming for a bit.

Then I made the best investments I bought in a while, Thermalright SI-120 (with lga775 bracket) and a zalman cu700 for my vid card...

temps max out o/c'd around 55c now after playing BF2 for a couple hours. Cant go wrong with the thermalright I dont think....but of course as bayboy already noted, without good case cooling it may not help as much.

Well I have pretty good case cooling, and a pretty good case. I have one of those tall black aluminum cases that look like the Apple G5 server case. Every panel of the case is like a mesh which lets air in from every angle. It has a case fan in the bottom front letting air in, a case fan in the rear next to the proc letting air in as well, a case fan on the side panel sucking air in, a case fan on the roof of the case blowing air out, a HUGE fan on the bottom of the power supply sucking air out through the PSU and out the back of the PSU. I also have an ATI X850 XT Platinum Edition video card which takes up two slots because of the built-in cooling unit that blows the hot air from the GPU out the back of the case. My case temp is like 30 degrees celcius or 80 degrees farenheit, only 10 degrees above room temp. I have been giving that Zalman CNPS9500 LED cooler a good look. Its that crazy round looking one with 6 heat pipes that blow the heat off the rig sideways. Every reviewer I read about it had awesome marks on it including Maximum PC. They say it beats lots of water coolers including the Zalman Resorator.

BOOM! I found the problem! The side-panel to my case had this plastic air scoop thing attached to the side and when you put the panel on it sits right over the air intake leading to the processor. I ran Prime95 max heat setting with the case completely intact, it spiked at 66 degrees celcius. I removed the case panel and removed the plastic air scoop and put the case side back on and watched with awe the thermals drop from 66 degrees celcius to 51 degrees celcius and holding steady for an hour with a +/- 1 degree fluctuation. W00T!

That is good you found a simple solution, but if you want to OC more I would suggest a better HSF like Batboy suggested.
