Review on Rosewill 120mm Case Fan 4-Pack, Long Life Sleeve Bearing Computer Case Fan ROCF-13001, Ultra Quiet Cooling Fan 4 Pack 120 mm Standard Fan by Seth Gibbons

This is exactly what I paid for. Four simple black fans that spin and push air out. Mind you, they don't push *tons* of air out. It would be inconvenient to use them in a system running hot components. My computer runs a GTX 750, 16GB DDR3-1333 and an i7-4790k, so it doesn't bother me that much. I took the first one out of the box, plugged it in and screwed it into the back of the case. and it worked. No hassle needed. It took less than five minutes to get the old dead fan out and put the new one in. They should go well with my new Rosewill computer case coming soon, I just wanted to use one of these on my old computer with a dead fan. Highly recommended. Can't beat $20 for four.
