Perfect CPU cooler
Almost everything is perfect. Almost goes to the side where screws for the pump SHOULD be little bit longer.

Great Performance
The build quality is really good, I used it on a AM5 system and it's got really good performance.AM5 has a weird IHS so it gets warm no matter what but compared to other coolers iv not seen my cpu go past 75 degrees c which is better than the last cooler I had that could go up to 90-95.It fits perfectly, the default fans are OK but I'd recommend buying some p14 max or something and adding them or buying 3 more p14's to make it a push pull but by default very good.

1 Star.
The mounting screws were broken so I couldn't mount it I tested it though and it got 40-45C on idle average. Mounting screws require a ton of pressure which may/will cause you to get a blister. Not reccomended. Also the cooler is very large physically and heavy.

Not suitable for all motherboards.
I recommend having insurance for newer x870e series. I had serious concerns with installing in my MSI MAG X870e. I wasted all my thermal grizzly trying to screw it down. It turns out that the screws have a gait so getting them I place with thermal paste is a nightmare. It was impossible following the instructions. The only way to do it was to screw in place from the 4 screw mounts rather than the 2 screw plate which took some effort and a 2nd steady pair of hands. 2 grams of thermal grizzly later and I had to settle for the MX-6 that it came with. I’m very unsatisfied.
