I went through the process of cleaning and then installing this conductive material to my heat sink.

Under heavy gaming conditions i see about 3-4 Celsius cooler temps on my cpu (air cooled with spire 2 eclipse heat sink)

I also cleaned out the fan and all of the cooling fins on the heat sink

Since replacing the fan would also mean replacing the entire heat sink assembly, I ordered this stuff to use when repasting the heatsink.

Put this on my MacBook Pro 2012's CPU/heat-sink assembly, and this did absolutely nothing

Temps seem to be acceptable and now I notice while the bottom gets warm during hours of game play, it's no where near as hot as it has been.

I attached a size comparison pic with this review and overall, yes, you should go buy this, but get it as cheap as you can

It seems to be working better, and doesn’t stall nearly as often
