Summary: I originally got one for my sister to cool her 980T, and ti worked beautifully @ 4GHZ. Since it worked nicely for her, I got one for myself to cool my FX-8350, and it cannot cool at stock speeds.
Pros: Relative light weight.
Quite stock fan.
Cons: Not suited for Vishera CPUs
Custom mounting hardware.
Stock fan has low CFM, and fixed at 1200 RPM
Cannot effectively cool CPU (FX-8350) at stock speeds while running Prime95. (second pass, temps @ +65C)
