Nice Fans, November 30, 2009

I bought 2 of these to replace the fans that came in my case. I am very happy with these so far. They are very quiet and move plenty of air.My case temp hit about 40c tops with the fans set at the lowest speed setting in the BIOS.I have 2 Radeon 4770 cards running in crossfire mode, as well as having my system overclocked.

A tool that works and is reasonably priced. What more could you ask for?

Great fan for the money., November 9, 2009

I didn't think I was going to get much quality for $10, but I was pleasantly surprised. This fan does provide a nice amount of air and is very quiet. I used these after using some Antec Tri Cool fans and the fan is a lot dimmer in light output which I find as a plus. You can still see the light but it won't light up a room at night. It does not have a speed switch like my previous Antec, but since it's so quiet it's not really an issue.
