I have two of these in a CM Storm Scout case. I am surprised on how much cooler they’ve made my case. These are some really quiet fans also.

This is such a great buy! it works perfectly, and noticed 2-3 temperature drop from inside my computer after replacing all the fans with this. Its not really loud but its not exactly the most quiet fan. Rating: 4 / 5

I bought these fans to go with my Cooler master Scout case. They are acutally pretty quiet and are not that bright. If you are looking for bright led case fans then look elsewhere, but the cfm are worth it. Rating: 5 / 5

Mine are running at 1800 rpm and are very noisy. My GPU’s are running 3 degrees cooler but I’m not sure if it’s worth it for the noise. I’m trying to slow them down but my EVGA X58 mobo doesn’t seem to be able to control it below 100% output. So at 50% output I might only get a degree or two of cooling on the GPU’s. I have yet to try to tap these into the chassis power to see what RPM they run at. Right now they are plugged into the motherboard. I do like the red LED lights though. I would rate these a star or two higher if I could get the to work properly, which is more because of the mobo I’m sure.

This fans are great performers and they are worth every penny. I certainly love the finish of the fans. Rating: 5 / 5
