Review on Rosewill 120mm Case Fan 4-Pack, Long Life Sleeve Bearing Computer Case Fan ROCF-13001, Ultra Quiet Cooling Fan 4 Pack 120 mm Standard Fan by David Carmody

Wow. I'm usually a Roseville fan (pun intended). However, these fans need help. Background - I replaced two factory 120mm fans in my upgraded Zalman case with three of the same Rosewill 120mm fans. Yes, I added an extra fan. My case holds up to five 120mm fans. I was very surprised to find that my six drive array running at 7200 RPM was hot enough to burn my hand. This has never happened before. I went online and bought a competing model, albeit twice the price. The new fan is rated at twice the CFM but appears to be closer to 4x actual performance levels. A good fan can keep my drives cool enough. Pros: These fans are very quiet and look well built. They should be quiet considering they move almost no air. The Bad: At full speed, these things barely move enough air to be felt. I really had to check if they were spinning.
