Does it harm a CPU to run it around 45-55C?
 
Is it just me, or is it really difficult to seat an LGA775 HSF?

Anyways, it took me 15 mins of shuffling and such to get my HSF seated, and I'm sure some of the thermal paste isn't perfect. My CPU runs around 55C on load (not OC'd) and 46C idle.

My question is, do I need to go back and do this 100% right, or is my CPU fine?

P.S. if anyone has any advice on how to seat a LGA775 HSF, I'm al ears.

Dude if you don't think you did it right then odds are you didn't. I'm guessing you're using a stock heatsink so the pushpins can sometimes be "tricky".

What program are you using to stress the CPU? 45C sounds awfully high.

What program are you using to monitor temperatures?
What CPU is this?

And no, 45-55C temperatures will not harm your CPU. In fact, it is quite literally impossible to harm your CPU with high temperatures since it will shut itself down before it can get hot enough for that.

Can't really tell if you're being sarcastic or not. 45C is totally fine, and it's normal to get that on air cooling. 55C on load is normal too.

I've done it before, this is the 3rd time I've put on a HSF for a LGA775 build. I've done it wrong before, the HSF will feel loose and temperatures will creep up really fast. The HSF is tight, and it's on right.

CoreTemp32, its a E6600, using Zalman STG-1 thermal paste

It was running cooler than that on stock HSF, was about 38-50. Wanted a quieter build, so have an Arctic Cooling Freezer 7 in there now.

If it's not going to do any harm to the CPU, I'm happy at these temperatures.

Thanks guys!

Until you start getting into the 80s or higher you have nothing to worry about at full load and as Zero stated, the computer is suppose to eventually throttle down your speed and shut it down if it reaches unsafe temperatures.

I've run CPUs at over 100C punishing heatsinks for reviews. They will throttle before they are damaged.

I agree that those LGA7575 heatsinks are a big pain to put on. I really dont understand why they made it like that (maybe to make sure its really tight? I dont know =/ ). That temperature is perfectly fine, Mine runs up to around 50 or so on load but however mine IS overclocked. Regardless, the cpu can definitely handle temperatures much higher than that anyways as people have stated before me.

Little offtopic, but we're playing around with 980 (6core) at work, the bios doesnt fully support it - so its not throttling, the heatsink is limited to a small space, and cpu max temp is supposed to be 67 degrees. They are hitting about 75 then locking up, but we have one stable at 85. Im thinking it wont last too long before it burns out.
