Summary: I would buy another if I had the chance, but not for $9.99. Maybe if it went on sale
Pros: Quiet fan. Spins silently and smoothly.
Cons: It's got weird silicone pins. They're ok, but I would much prefer standard screws. No directions, just a picture on the outside of the box. You have to pull the pins pretty hard to get them to snap into place. I thought I was going to break them. But they worked out ok. Could push a little more air.
Summary: Given how much air it moves and it's size, anyone could logically deduce it will be loud. Get a fan controller and turn it up as needed.
Pros: Moves a massive amount of air.
Cons: You can pretty much never remove the pins once they've been inserted, thus your fan is going to need to be a permanent fixture in your case. I'm sure I'll just use regular screws once I can find me some.
Summary: Zalman makes great cooling products. This fan is no exception. But their mounting "innovation" leaves much to be desired.
Pros: This fan moves a good volume of air and does it quietly. It also will hook up to the motherboard so the speed can be monitored. GREAT!
Cons: Whoever thought up the idea to use those little rubber mounts needs his head examined. After fiddling with the stupid things for nearly an hour (and breaking two of them) I just gave up and put a rubber mount on the fan and used normal fan screws. They _should_ include fan screws for people who d...
Pros: This is such a quiet fan and does exactly what its supposed to do. Lowers the temperature of my case by a few degrees. (Once I had it blowing out instead of in :P)
Cons: The only bad thing I can say about this fan i show it actually attachs to the case. It uses silicone pins that stretch through the case and then through the fan. These pins tear very easily and if you don't get it on right the first time you are pretty much stuck with it ir take the chance of tea...
