Building a new computer and I need a Thermal Paste for it

I don't have skylake CPU, but Artic Silver 5 is a great thermal compound that you can easily find locally or online.

Artic Silver 5 is a good bet. In reality, they all perform good and are pretty close in temps.

I deleted your other thread, don't make more than 1.

I avoid AS5 for three reasons:

1. It takes 200 hours of **thermal cycling** to cure ... not 200 hours of use. Even if it was just use .... that's 7 weeks at 30 hours per week.

Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

2. It's capacitive

(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

3. There are products available for less cost that have the same thermal conductivity but w/o the above issues

I switched from AS5 to Noctua NH-N1 as my go to thermal compound. I tried a number of highly rated compounds and aside from the fact that most do about the same job, the Noctua is easy to apply, non conductive and no burn in time. The only thing AS5 has in its favor really is its easy to get a hold of (I've had to do the unexpected run to Radio Shack before) but if you're ordering parts it wont take any more time.

My vote goes to Gelid Solutions GC-Extreme http://www.amazon.com/Gelid-Solutions-GC-Extreme-Com.... Check out this extensive list of thermal pastes and their performance as well as characteristics. The guy that did this really did a fantastic job so I'm all about directing people to this information and no, I don't know him.

The Gelid is a great TIM. But you have to warm it up to apply it easily.
