Summary: It's a nice basic type fan. The noise level is good and it really pumps out some air compared to the 120mm i replaced. I docked 1 star because it only came with 2 screws and the screw holes are a little to small, made it take some irregular force to get them locked in tight. It did come with a power supply adapter in case you don't have enough open fan pins available.
Summary: Fan was easy to install of course. Came with the adapter to hook it into the motherboard. I recommend this to any first time builder or even a pro builder. Only thing i disliked was there wasn't much of a manual.
Summary: Three months in I turned my computer on, heard the fan make a terrible racket, touched the top of the case and POP! A blade broke right off. I wasn't super happy with it to begin with (it was louder than I expected) so maybe I was unlucky and got a bad one. Still, that shouldn't be happening. I'm just glad the flying fin didn't break anything.
Summary: Worked great until it almost caught on fire! I had 4 of these installed and one seized entirely and almost caught on fire. Thank god I smelled the burning plastic/electrical smell before an actual fire started. I thought this was no big deal (things happen) so I replaced it. One of the other ones started making a grinding sound a couple months later. Hell no I'm not risking burning down my house! Replaced all four of these expensive paper weights. Use at your own risk!
Summary: Not much to say, it's a quiet 140mm fan that works great. I tried a 120mm fan in my honeycomb grill and it made a loud jet noise. This 140mm fan in the same honeycomb grill on my computer case is nearly silent. Get this fan, it rocks.
Summary: Based on Amazon reviews and computer enthusiasts' forums I purchased 2 NZXT 140mm fans to replace a dead fan. I tend to buy such items in pairs/quantity (sometimes as a backup). NZXT fans have a reputation for being quiet; and this is usually true of larger fans as well. I consider it to be at least quieter than the one that it replaced, and it moves a lot of air. This is my first use of a fan with "rifle bearings" so I'm hoping for increased life.
