I wanted a blue theme for my computer, and chose because it had a blue led on it, plus the reviews on it were good, results show it a great fan, if you want to keep the CPU at stock settings, or even OC a little.
I keep my Cpu OC at 2.7 from 2.4 ghz. Playing Crysis never exceeds 47C to me is excellent.
The most I could get the CPU stable was 2.8Ghz, but it runs hot as heck, over 50C when playing Crysis, I like to keep my CPU's under 50C.
Here is a picture of my case with the fan:
