Perfect choice with 5 9600X

I used this cooler with a 5 9600X and it's fantastic. The processor stays ice cold. Not to mention, it was super easy to install, with is a huge plus for me, as I have some motor skill issues.

Great!

I use my machine at 100% load a lot and it never overheats. It's been really nice and a very needed upgrade.
