I have one *cool* core!

post #1 of 9
Thread Starter 
Running an i7-950 @ 4.0
Under stress test I get:
core 1 & 4 @ 73c
core #2 @ 74c and cor #3 @ 69c
Is this normal and within range? I guess it just means my cpu is perfectly flat.
No, I don't want to lap it. Just was wondering what other people get.

Yes, 3-8c is normal between cores.

Thought so. Just wasn't sure. Seemed weird that two were exact and one core stayed 1 degree off. Then core 3 is always 4 - 5 degrees cooler than the warmest.

Yea its normal, no need to worry. If there is a 10*c+ difference, then you start to worry

Which usually just means reseat your heatsink anyways

Yes it's normal.

My fourth core tends to run a lot cooler than my others.

Some say it's uneven TIM spreading but I disagree.
post #6 of 9
under stress test, 2 cores are usually 4-5C higher that my other 2 cores.
Its fine ...
You should see the difference the new i7s get ... Got people a little scared when they saw 10C difference between the first core and the last

This is why people lap their cpu's?
Just the thought of taking my cpu and rubbing upside down on grit scares the death out of me. Even when I'm just installing it, I'm worried about bending a pin.

same as everyone else, one core a bit cooler than the rest.

No lapping it wont change that, it will just make all 4 run a bit cooler than non lapped but the coolest will remain the coolest.

If you run with HT off the difference isnt as great, but with HT on when it gets to the 7th and 8th thread its just not as demanding as the first 6.. Thats my theory anyway..
