Arctic Silver variations?

andy497 · 03-06-2005, 05:29 PM

I've still got a stockpile of Arctic Silver 2 that I'm working through. I'm putting in new blocks now, and I wonder if it's worth it to move up to 5, ceramique, etc.

I know they have some published numbers on their site, but if I read it correctly, AS2 actually has a lower C/W number than AS5. I'm guessing that's not right. Given that the block/die junction is probably the most important part in a cooling system, do these different iterations of transfer compounds make a big difference? Most folks would probably never know for sure, but I'm guessing some of you procoolers have tested the same system with different pastes.

Just use some toothpaste

Honestly you might see 1-2C difference between AS2 and AS5, but unless you're pushing for the absolute last percent performance I don't see it as really being significant.

Eh. I like Nanotherm PCM+ personally. Prior to this, I used Ceramique.

Incoherent's,possibly definitive , measurements reported here .

Note the measurements are for a 144mm^2 interface under a PRESSURE of 13.9 kgf/cm2

What the heck is SX 25?

And anything to relate that pressure to?

SX-25 is a prototype grease for testing.

The pressure I used is rather approximate. I used force sensitive resistors to measure the force applied by the four mounting springs I use when they are compressed a certain amount. I did all the tests with the springs compressed this same amount. This amounts to approximately 20kg of pressure on 1.44cm^2. About 13.9kgf/cm^2.
