Not as expected

Nodone,, TigerDirect.com

  • Summary: I have the 92mm version of this fan, and it's a lot quieter. At low speed (around under 1000rpm), this 120mm fan is silent, but as soon as it gets higher, its loud. Decent fan for the price.

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: 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.

If you need control; these perform!

  • Summary: My PC is mounted in a semi, therefore I face some extreme ambient thermal conditions. I ordered 10 of these, 2 as pull fans for my 240L and the other 8 as case fans in my Thor V2. Using fanXpert2, I'm able to idle the 4 side fans and the pull fans at 575rpm,Silent! The other 4 don't even power up 'til I hit 60 C, and then only run at 800-900rpm.
