4th core temp higher than the others

post #1 of 11
Thread Starter 
Hi guys,

Just wanna clear out something that bothers me from days...
Check the attached realtemp pic. It shows my normal idle CPU temps. As you can see though, the 4th core has a temperature that it's (a lot) higher than the other cores. This is a costant difference, even under load.

Ideas? I though the thermal paste could've been applied in the wrong way, but it was already spreaded in my Corsair H70...

at maximum temps i always have one core that is about 3-5deg hotter than the rest.

i dont see any problems here. if there were any it would be very apparent under load.

its normal, mine does the same thing but my 4th core is actually lower than my first 3 cores. I'm sitting at 35/34/35/28_ After reapplying thermal paste too many times, I gave up and said its normal_ It seems common for intel(as I've googled knowledge so far)

under load it may go even up to 10°C difference!.. depends on the application you are using.. depends on how many cores it uses and how the cpu handles with the app.

My 2nd core is always a good deal hotter than the rest. Very normal. Also, sometimes the sensors can be placed badly, that can cause the difference.

Nice to know that, thanks to everyone!

Mine was the same way until I lapped my processor and heatsink. No change in temps really just made them stay within 1*-3*c of one another. My c2d had horrible temp variations and it lived through 3.93ghz (e6500 on air) lol.

What do you mean with 'lapped'?

sanded and polished the heat spreader of the cpu down to copper... it evens out and lowers core temps substantially... well it evens them substantially but lowers them 5-10 degrees on average which too some people is huge
I lapped my Q6700 and it made a world of difference with temps and all cores stay within 1-4 degress of each other constantly
