Summary: My last computer case fan, 120mm in size, capable of moving a 64cfm of air at 22db was produced by a brand-x company. The brand-x product had an inherent design flaw causing it to explode during normal operation. This happened to me and I will no longer purchase brand-x products.
Pros: Its a fan. It makes air move in one direction. It did not explode when powered up.
Summary: If you've never used the rubber "screws" before, they can take a few tries to get the hang of, but seem to make a big difference. I'm not sure how removal will work. Product worked so well I've ordered a second on.
Pros: - Very quiet (not silent, but quiet enough for a living room PC) - comes with all hardware - clear instructions for rubber "screws"
Summary: (1) If you need reliable fans, here you go. (2) I don't mind learning how to use the Silicon pins, but Zalman should have included screws, just in case silicon pins were not a viable options for where they are placed. (3) I would recommend Zalman fans to my friends.
Pros: (1) Bought four for twenty, with free shipping. (2) Fast and quiet (but that's relative).

My case (Cooler Master Stormtrooper) has dust screens on the bottom, which the Silicon pins block from taking off for cleaning and/or putting back on. The two fans I ...
Summary: I have a Zalman fan speed controller that requires 3 wire variable speed fans in order to operate. These Zalman fans work perfect. I'm using 2 of these guys in a push/pull configuration, for the radiator on my Coolit Systems ECCO that's still going strong for over 2 years.
Pros: They move a lot of air and they're semi-quiet. They're also inexpensive. I know Scythe fans are the cool thing to buy these days but you can't go wrong with these.
