Overall Review: Keeps my Ryzen 5 2600 at 4.1 OC at 72 degrees or below under a stress test. I've heard of complaints of mounting difficulty. I didnt have any issues at all. I like the all blacked out look. I was thinking about adding a pull fan to the other side of the cooler, but I don't think it will be necessary at the temps I'm getting. Great product.

The button to turn it on doesn't work great. It cycles through 3 speed. Do I push it? Do I hold it? I'm not sure. The button feels cheap. It's finicky. The suction side seems fine, has a filter and compartment to hold dust and debris that seems to work decent. Decent power for blowing g dust out. Battery seems not good. If the switch worked better, I'd probably like it more.
