Customer Reviews

• I got a lemon

• Review: The fan blows a lot of air as it is supposed to. It is not silent but is not overly loud.
  The unit I got seems not to be balanced properly, so there is a vibration added to my case (HAF922) as I am using it. If I hold it in my hand while it is running I also feel this vibration. No sense returning to amazon.

• nice fan.

• Rating:
• Review: nice fan. moves a respectable amount of air with little noise.. it's not silent by any means, but you will be adding a low-pitched 'wooooshing' sound to your system... tho this is a small price to pay for proper ventillation.

• Great fan - wouldn't mind getting another

• Rating:
• Review: I got this to replace a fan that came with my case after the bearings seized up, and I have no regrets. It's no noisier than the original, but it moves a lot more air. My CPU temps dropped 5 degrees C from where they were before. It also has no annoying LEDs.

• Very cool!!

• Rating:
• Review: Yes very cool on every level. The fans are great and have decreased my system temp by about 10 degrees C. System runs consistent at 30C now. They move a lot of air for sure, but they do make noise so if you're looking for a quiet system not the way to go. Since I am only concerned with performance it is perfect. When playing MP3s at normal levels the noise is not noticeable to me.
  
  I'm very happy with the purchase.
