Orthos, core temps hitting 65C

post #1 of 7
Thread Starter 
From what I've read these temps are high. I shut down as soon as I saw it get to 65 in test 7 of the blended stress test. I tried Stresscpu with Gromacs and the temps spiked right away. A couple of things other than that the temps seem fine. I'm running at 3.43 ghz 266x13 and 1.425 vcore. All my ram timings are set at Auto. Another thing is I'm using a Zalman thermal paste not AS5... could that be it? Possibly reseat the heatsink? I'm confused because like I said the temps stay acceptable everywhere else.

You can try to reseat your CPU cooler... make sure your CPU heatspreader is flat... also the HSF is flat... if not you can try lapping.. it helps a lot!

I would re-seat the heatsink, but I am having similar problems with my watercooling loop, and that didn't help. But you shold try that. Use very little thermal compound, just enough to fill in the microscopic cracks in the metal. I spread it around on the CPU with a toothpick, others just put a BB sized dot on the middle and clamp it down to spread it out.

65C is a tad high ... but if you cared to get into a winded debate with intel technicians present ... they'd probably tell you it's not going to hurt anything.

In other words ... no need to shut down your computer or anything ...

You can improve it a few degrees or more by using a different CPU cooler/cooling method or possibly checking the mount of your current cooler.

Also, your CPU should throttle at unsafe heat levels and so at 65C, there's really no reason to get too freaked.

Thanks everyone, been away for a coupla days and appreciate the responses. I'm planning on doing a reseat and go from there.

I actually got some new info about the thermal paste application on C2D chips. Here is a photo:



Spread a 1mm thin line over the core area and you will have a perfect thermal interface. Hope that helps.

It took a while but I have my temps down to a reasonable level. It only took an upgraded fan, lapping the heatsink and about 4 reseats before I got it right. Remarkable difference though. I was running Orthos at stock to check on things and when things weren't right I was getting upwards of 65C when using small fft's to stress the cpu. In comparison, now when I tested it the temps never got above 52C. I was doing all this at 22C ambient with good air flow through my case too.
Many Thanks for all the help.
