Thermal paste amount?

post #1 of 26
Thread Starter 
I have just installed a Thermaltake frio OCK on a 2600k at 4.5ghz on 1.13v. I think i may have put too much thermal paste as the cpu is running at 34degrees on idle with a 22 degree ambient temperature.

1. Is this normal?
2. What's the difference between too much and too little thermal paste?
3. This is a pic of it448

Clean the CPU with rubbing alcohol
LET IT DRY!! (don't be like me and impatiently put the TIM on too early, then watch as it slides around on the alcohol, rendered completely useless)
Put a Pea sized (no bigger) dab in the middle of the CPU - no spreading!
Plop the cooler squarely down on top - minimal twisting and absolutely no swaying side to side
Secure screws in start pattern

Too little = temperature increase
Too much = temperature increase

Clean it off with alcohol, apply pea sized amount, let the HS spread it as you put it on.

From looking at that picture - yes.

34 degrees idle is pretty normal, though. Have you tried stressing?

Yes, with a burn in test the max temp I got was 63 degrees. Would you say that's a good result for the cooler or should i re-apply the thermal paste?
post #9 of 26
I think people worry too much about putting too much on, as when you put a dab in the middle, a rice size to pea size then put the heatsink on it will spread out, most of the extra is usually squeezed out of the gaps on the sides and the actual thermal interface is generally the same thickness as its the pressure from the heatsink that determines how much gets squeezed out.
I've replaced hundreds of cpu's and don't put much care into it anymore, I just throw a glob on in the middle and call it good.
Some people like to use a pattern, a spiral or an x shape or even tape off the sides and apply the compound evenly across the whole top,
As long as its on there and covering most of the cpu when you take the heatsink off an check, you should be fine.
Every cpu and heatsink combo is a little different and the only way to know for sure of an exact amount is to do trial and error, with different sized globs and different patterns to create the most even amount with the least amount of tim squeezed out.

if i redo the thermal paste with a thin amount will it be cooler than it currently is by a significant amount (>5degrees cooler on full load)
