wow seems like someone bought and switched returned to amazon.
This is why they really need to set up tracking numbers or have people at return know what they are accepting.
I do not like ICDiamond... it etches your heatsinks / ihs / anything you apply on, and you can never get it off unless you relap the surface.
I like MX-4 its cheap, its not the best, but were talking about a couple of C's from the best vs worst. Its consistent and easy to apply.
I do not like Kyronaut, its just too overpriced for what you really get, its good stuff, but just way too overpriced for that 1-2C
coretemp which is negligible IRL ... personally i am not a fan of Debaur products. Again majorly overpriced.
My personal favorite is Prolimatech PK-3. Its right in the middle for price vs performance. It has very consistant mount, meaning the spread for a bad application to a perfect application is within 1C, so you don't get much float variance.
It lasts a while, and again, its not super overpriced vs Kryonaut.
Special shout out to ICPAD.
Amazon.com: Innovation Cooling IC Graphite Thermal Pad (90 x90 mm): Computers & Accessories
www.amazon.com
I use these on my servers and OEM builds where overclocking is not important.
It gets really close to thermal paste in OEM builds, it has a much greater X axis transfer over thermal paste, and it lasts almost forever, so you don't need to worry about ever replacing it.
90x90 pad will be good for about 9 builds if were looking at 30x30 cut out.
Again, for non overclocking situations / servers i can not find any fault or flaw in it.
