I was just watching prime85 while watching the core temperatures and I noticed that the fan speed doesnt make a difference whatsoever. I have a Tuniq CR-T120 cooler which is supposed to be pretty good. Shouldnt changing the fan speed from really low to max change the temperature a couple degrees if everything was set up right? It has the same effect, or lack of, at both idle and 100%. What do you guys think?

Lets see, I just built this computer a couple weeks ago. I used silver arctic thermal paste, spreading it evenly over the surface of the chip with a credit card. In my opinion it was a small amount, but unless you are supposed to use a tiny amount only? Anyway, I've been doing quite a bit of testing and was satisfied with the results in terms of temps, ie less than 72-74c at full load running a 2.13 at 2.95. But now im noticing that the fan speed doesnt change the temperature in a measurable way at all, and i mean the difference is between silent on low to bothering my roommates loud on high.

you ought NOT use a credit card and spread the TP, it will cause air pockets when you install the heatsink. a line or pea sized dot in the middle is best.

thats the problem.


@amuffin didn't someone post a you tube video showing the different way by pressing down a piece of glass on your how to apply TP thread you have?

Awesome, I put thermal paste on the right way and it got about 15-20 degrees cooler under load. Was definitely worth the extra work, thanks!
