Guru3D Thermal Paste Roundup 2019

Thermal paste is an often-overlooked part of most computer setups. You can simply use the pre-applied stuff, or the thermal paste that comes with your motherboard, and still get reasonable processor temps at stock speeds. Thermal paste is a compound that helps to fill the gap between the CPU and a custom cooler.

Using MX4 on my new 3900X build and very happy with it. Started with Kyronaut but found it hard to spread, even after warming it in hot water. When I removed the cooler it was almost chalky, so switched to MX4 as I'd had good experiences with Arctic Silver before.

I've always been using Arctic MX-4, but then again it cost like ~$5 and I just want to replace the stock compound.

MX4 is pretty bad nowadays. Loses all its properties in just weeks. And doing even worse. Nice temps you are only getting for a short term, but eventually you can end up with temperatures much higher, than before MX4. A lot of thermal pastes are actually drying out pretty quick and losing thermal properties. So longevity tests would be much more useful, than thermal.

I have the same experience with MX4. After 2 weeks the Temp went up by 10C, and it looked all watery.

I'll stick to Noctua NT-H1 on my CPU and GPU like i have been doing for the past 10 years. It doesn't dry out either. I recently applied new paste after 2 years and the temps were the same.
