Review on UTUO Variable Exhaust Adjustable Centrifugal by Tim Harrington

Bought this fan for GPU mining cooling. And it's absolutely the best fan I've ever had, it's completely different from a regular fan. I have a 220cfm fan that bleeds air out of my cards and when I remove and reseat the 220cfm fan my GPU temp drops by 5C. Although a 220cfm fan pushes more air , is a blower fan has a much stronger vacuum. And he did exactly what I needed. My GPU went from 54 to 49 degrees Celsius, incredible results. It's definitely loud, but I give it a good rating because I have three other fans that are louder than it, and it's quieter than my GPU's turbo fans.
