Cores running different temperatures

post #1 of 15
Thread Starter 
My cores are all running different temperatures. I don't expect them to be the same, but this seems odd. My coolest core runs at 25 idle, while the warmest core is 36. The other two cores are 33. Its that 11 degree difference that has me worried.

At load they all run about the same (64), except for that cool core that runs 57. Should I reseat my heatsink or is this nothing out of the ordinary. Thanks.

Also, this is with PWM. When I had the fan on full at idle the spread was about 23 to 28 degrees.

Well,

I wouldn't worry about idle temps as these frequently go wrong. Your on load temps are a bit odd and a reseat wouldn't hurt at all. Make sure you use the rice grain for your thermal paste as well biggrin.gif

Different temps on different cores are not an unusual thing. And yes, the load temps are the ones that count. A proper reseat would certainly work

Thats what I was thinking. Unfortunately with this corsair heatsink there's nothing holding the backplate on, so unless I grow a third hand I need to remove the mobo. Oh well, at least its a weekend.

Even with the direct touch you'd use the grain of rice? I was thinking of doing a line on each heat pipe. Currently I had a line on each heat pipe, with a bit of fill-in from when I flipped it (so I know it wasn't very good).

Since I want to do it right this time, any suggestion on paste? I have the Dow Corning that came with it, I have a three year old tube of Ceramique (does it go bad?), or I can get some better quality stuff at MC.

Is this any good: Shin-Etsu X23-7762

Go get some artic silver 5 or some MX3 I think it is, I personally use IC Diamond 24 carat, but it's a bit much for some peoples budget.

I'll pick up the mx4 tomorrow. Looks like it might be quite a bit better than the stuff that came with it.

Arctic Silver 5 is no better than others, is stiff to apply and takes a long time before you know if you have set it properly. More recent ones are better and don't have such long setting times. The Shin-Etsu X23-7762 is pretty good, but look at this review.

As for core temps: Intel says that the further you get from Tj-max (about 100c) the less accurate those tiny sensors are: they're really designed to sense the approach of core temps to Tj-max so the chip can throttle itself down to avoid overheating. So uneven temps are to be expected. You don't know what those temps really are.

Uneven temps have nothing to do with your TIM, BTW.
