Dangerous i5 temps - What do I do?

My new i5 750 processor is running at over 80 degrees celsius in prime95! I've tried reseating the heatsink and reapplying thermal paste (AS5) at least four times now, and my case has pretty decent airflow. I'm starting to think that it might be a bad chip. Is there anything that I could've missed, or might I have to send it back to Intel?

are you overclocking? are you using the stock cooler? the stock cooler is pretty much garbage especially if you're OCing

I never use prime 95. But 80 celcius is not high enough to panic. If you're going to overclock, use a copper heatpipe heatsink with 120mm fan; for 92mm size, slickdeals.net had one listed for $6 after $10 rebate today that beats the stock Intel unit.

I'm not overclocking, but I am using the stock cooler. The core i5 does have the Turbo Boost, which will kick the cpu up to 2.8GHz under load by upping the multiplier. I see the consenus so far is that I should buy some kind of new heatsink - how do I know what to look for in a good HSF?

Is your heatsink mounted properly?


80'C running prime95 for stock cooling is no surprise for an i7 920, but for an i5 that's a bit high.

Any aftermarket cooler would be good as long as it's not stock cooler.
Arctic Freezer from arctic cooler or thermaltake's products is good... :)

I've mounted it and re-mounted it a number of times... I don't see how I could've consistently messed it up like that, unless there's some secret to the Intel HSF.

Hello there

I was wondering how was your temp!?

I know it been a long time but....

If you still have the probleme could you post a screenshot of CPUz application on the cpu tab?

I'm curious about wich configuration your motherboard set as default... as you said you didn't raise any frequences..

And finally, why don't you use IntelBurnTest that has been write for Intel.. ? xD

anyways, have a good day
