i would think the second one is better, since it moves much more air, and its nicer looking. the problem is, my case is really small, and im not sure it will fit. i dont have a ruler handy
the arctic cpu fan is cheap, but the problem is that my cpu is, for some inexplicable reason, right under my power supply, and i dont want hot air to be blowing into it. theres no space in my case to point the fan any other way, i dont think. i think i have maybe 125 * 125 mm free space parallel to the motherboard * 150 mm tall. i have this case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811166006
is there any other somewhat cheap q6600 fan that looks good and blows air like crazy toward the side of the case?
