Cpu Grease - computer heatsinks, cpu


Ok here is some tech talk that you may or may not understand... When connecting to hot metals together the thermal transference is around 10-20% which is great if you're not to worried about heat. In a computer where heat is not your freind it is a big, really big concern, which is why we use a thermal grease with most you get a thermal transfer rate of about 30-50% which is fantastic if you're just running PII- PIV processor. But for those of us using a high end system with the added problem of living in the caribbean with the current heat wave Artic Silver is the only way to go with a thermal transfer rate of 50-70% its a great way to add a little extra protection with out incurring a big cost.



Just one thing though, the shipping of this product is sent via an envelope which means that the tube can get damaged, I've already complained about it to the company, and I'll update you as I will be using this product regularly if that doesn't change. Laterz peoples Arctic Silver C?ramique 22g High-Density Thermal Grease CPU Heat Sink Compound

Artic Silver has never let me down with their products. Their quaility control is excellent.



Pros

-non conductive

-non capacitive

-non bleeding

-8 year life span

-not thick or hard to apply



Negs

-not the best at thermal transmission

-pricey



The difference between this paste and the top of the line paste according to the comparison with the best methodogy I found online was 2.3 degrees. But that product was conductive and the other products that werent conductive that beat ceramique were either hard to find (shin-etsu), or were hard to apply (IC-7, which requires 50 psi of force). Naw, I'll stick with AS cermaique: name brand, safe, easy to apply.



Note: the 2.3 degree difference was between pastes. There are some phase change metallic compounds with 8-10 degree superior performance, but there are major downsides to them (eg. Indigo Xtreme requires you heating your chip up to 95 degrees celcius).



Note 2: apply the product according to the manufacturer's recommendations. Don't apply it according to some guy on a forum's instructions.
