The best on the market.
Installed on a Ryzen 7 9800x3D processor and paired with an Arctic Freezer III Pro 360mm liquid cooler.

Easy to apply and very good performance.

Everything is fine, I'm not saying otherwise, the performance is 1-2 degrees lower than the Noctua I had and I wouldn't change it, I just had to do a surgery on the PC and I had to renew the paste since I removed the cooler from above.. but it spreads quite difficult, especially with this nozzle they provide. It's not something amazing.. it's just fine.. but if it's your first time, don't panic if you see it spreading strangely. It just requires a little patience

The best paste on the market, BY FAR
I wouldn't change it. 10 degrees difference from the competition.
For lighter situations, Arctic MX-4

You may find it a bit difficult, as it is better to have thin coverage on the entire chip (CPU/GPU), but really, it's a different thing

First of all, it requires attention because it is electrically conductive.

Secondly, it is one of the best pastes, with the highest thermal conductivity.

On Asus R9 290X DC3OC, it reduces the temperature by 15 degrees with the stock cooler and without the stock paste. On GTX 980Ti with liquid cooling, the card runs at 25 degrees when idle (YouTube, Netflix, etc.) and the maximum temperature in games is 38 degrees. On AMD Ryzen 7950 with the stock IHS, it reduces the temperature by 5 degrees.
