Thermal Paste Comparison, Part Two: 39 Products Get Tested

Pastes: Xigmatek

Xigmatek PTI-G3606

Xigmatek’s entry-level paste is called PTI-G3606, and it sells at a mid-range price. Measured thermal performance is acceptable and its ease of use is even commendable. At the end of the day, this is a solid product at a fair price for mainstream hardware enthusiasts. It's simply not what we'd recommend for more hardcore overclockers.

Application HintsThis paste seems best suited for the "lentil ball" method, and should be used in average-temperature rooms, from 70 °F
Price (approximate)$6 (3 grams)

Xigmatek PTI-G4512

Xigmatek's premium thermal compound doesn't even cost more than its entry-level offering. But the trade-off for better thermal performance is higher viscosity. Before using it, warm this paste up. Although it's not really for beginners, we do get a good price/performance ratio out of the PTI-G4512 from Xigmatek.

Application HintsThe paste can be spread more easily if you warm it to 100-120 degrees Fahrenheit in a pot of water, sealed in a water-tight pouch.
Price (approximate)$6 (3 grams)

Xigmatek (Paste Bundled with Xigmatek Coolers)

This is another paste bundled with a cooler we picked up off the shelf. In our tests, the freebie fares slightly worse than Xigmatek's low-end aftermarket stuff, but not by much. It's an average compound that you shouldn't feel compelled to shy away from.
