Excerpt: I have 2 of these. One particular is excellent. It is powerful and quiet. Fantastic design and materials. Easy to install in AM2/AM3 program. Actually took 3 minutes to install.... ...The second one is a different matter. I installed and uninstalled the similar day. Very loud fan no matter what speed it operates at. Either the fan is out of balance or the bearings are defective. This device is now sitting on a shelf. I have been a Huge Zalman fanboy for years.
Excerpt: It cooled my Phenom X4 9950 at 3GHz ྭ-ᡇX) at an idle temp of 39-40C (about 7-8C below stock fan) LOUD LOUD LOUD...I study all the critiques and discounted the "It's actually loud/annoying tone" mainly because I have under no circumstances had anything but wonderful merchandise from Zalman.
Excerpt: it cools my processor ! It's so noisy! It sounds like somebody is flying a remote manage plane in my back yard. Seriously ! I keep looking out the back window. Then I look down and comprehend its my Computer! Emailed ZALMAN with no reply. Can't blame newegg they didn't make it. I have narrowed it down to a off balance fan causing vibration. If you like that BUZZZZZZZZ sound obtain 1. Newegg send a message and send all of your stock back to them.
Excerpt: Attractive. On sale w/free shipping. Even in silent mode, the fan makes an irritiating grinding noise. Minimal cooling advantage over AMD stock fan. The AMD clip mount is a PITA! Even with AS-5, the 9300 dropped my cpu idle temperature a not-so-impressive 3 degrees (from 32c to 29c).The AMD mounting clip is extremely poorly thought out. What, doesn't Zalman know that even the stock AMD coolers use a _lever_ mount?!
