GELID Solution's GC-Extreme Thermal Compound
Putting a glob on my old E6400, the first thing I noticed was the thinner viscosity of the GC-Extreme versus the GC-2. No stiff peak of compound present on the top of this sample when I pulled the syringe away. Let's see how well it spreads.
Unlike the GC-2, the thinner GC-Extreme levels out really well, even with the tip of a finger. I actually spread around the compound that was used for the previous image. I was left with a bit of compound on my finger, as expected, but the GC-Extreme doesn't clump and stick to your finger like the GC-2. To me, that's a plus, as I don't always know where my spreader is when I'm in the middle of a CPU swap or maintenance of a graphics card.
Using the processor as it was in the previous image, I clamped it all into a motherboard to show how well or how poorly the compound covers and spreads. This is the result I got from the finger spread method. You can see it covers really well.
Placing a similar amount in the center of the IHS and strapping down the cooler yields this result. Not exactly what I would call good coverage at all, on either the heatpipes or the IHS.
This is the result from the five dot method, as I used with the GC-2. This time the coverage isn't even as good as the results I got with the GC-2. I highly suggest the GC-Extreme be spread in a thin even layer for best results, and so does GELID. Why else would they send the spreader?
