Great value!

  • Summary: 01MAY14: Purchased four of these fans for my case to help with cooling and take advantage of my PWM slots on my mother board. I'm running the fx-8350 at 4.8GHZ which is kept in check with a H100I so there is a lot of heat to get out of the case. So far I'm impressed with these fans. At full bore they are just as noisy as the NZXT fans I had in, but at 76-77CFM these fans have done a great job in moving the air.

  • Summary: Before buying this item I checked the Q&A section to make sure this fan had mounting brackets for the Hyper 212 EVO. The answer given was that it came with the mounting brackets so I placed my order only to receive a product with no mounting brackets. I love cooler master products but now it looks like the only way I can get two mounting brackets is to buy an accessory kit which is a full kit for mounting the cooler but I do not need all of that.

  • Summary: Just that. Works fantastic but really damn loud. I think my PC sounds like it's a jet about to take off even when idling now.

  • Summary: I choose the fan as a replacement for a fan in my Thermaltake case. But had to return it because the fan did not have a Molex connector. Sure wish they would have shown me a picture of the connector, would have made my decision easier. On the plus side, the vendor and Amazon made the return process painless.

  • Summary: My machine used to hum and whine a bit, these fans were used to replace a few in my case and the noise has greatly reduced in level and annoyance.

  • Summary: Nice quality, but if want something silent at high rpm then walk away. I got three in my rig working for two years and i have no complaint about their performance.

  • Summary: dropped system temp by 5 - 10 degrees C over stock fans. No LEDs or fancy stuff, just efficient cooling.
