Just recently I discovered that the fan which came with my Cooler Master Hyper 212 Evo has stopped spinning. I purchased this cooling Unit on a MicroCenter about 7 months ago. I noticed it when I took a peak through my tinted side window and noticed that the temperature reading on my motherboard read 70 degrees Celsius and I was concerned. It spins when i unclamp it and try to make it spin with my fingers but as soon as I clamp it on the heatsink it just stops spinning in 3 seconds. I just can't get it to keep spinning. What are some good aftermarket fans to replace my current stock fans on the Hyper 212 Evo?
