EVGA FX 140mm Fan, Teflon Nano-Steel Bearing, Improves Chassis and Radiator Performance (400-HY-FX13-KR)

Pros: Used it as front air intake and it is WOW! Its good to have a fan controller on these so you can regulate the fan and as well as the noise.

Cons: The fan is loud which is understandable because it moves tons of air in to your system.

Pros: Works, spins, moves air well enough.

Cons: There's a low hum that's very distinct and noticeable, and annoying.

Overall Review: I've not played with the fan speed, don't know if I can on this setup, but at default speed the hum is just distracting, It took me a minute to figure out where it was coming from but it's definitely the fan. I splurged on the fan, should have just bought basic one, then at least I wouldn't be so annoyed at the dysfunction of it.

Pros: -High CFM -Static Pressure Design

Cons: -Not PWM (have to use Phantek's fan hub to speed control via voltage) -Louder than advertised (used DB meter)

Overall Review: Great fan for water-cooling setups using 140mm, 280mm, 420mm or 560mm radiators. I'm able to keep them at 40% speed via voltage using Phantek's fan hubs. Doing this keeps them low on the noise level and with them being high flow fans, they operate at other fans full speed but at a lower sound level.

Pros: fit perfect on my rad no issues, slick black doesn't disrupt color scheme, silent when off the rad

Cons: cant get them quiet, they make a whinny noise no matter what even with cushions on it, when I take them off the rad they are fine

Overall Review: would buy again if I had too

Pros: Very good air delivery at a reasonable noise level. You cannot really complain about noise if you are running a fan over 1500RPM or more. At full speed, they run very smoothly. And I suspect their ball bearing system will last many many years. How else could they offer a 3 year warranty on as case fan? They are an excellent choice if you need the extra air delivery from a 140mm fan, and also if you want a very high quality long lasting fan for use at lower speeds. You can mount them with the rubber isolation washers they give you, or just mount them as usual without them. I would not hesitate to recommend these to anybody!

Cons: Power cable length is a little shorter than some. In a large case, you may need a fan extension cable.

Overall Review: These are supplied with a fan connector to 4 pin molex adapter if you don't have a mobo connector available. They will, of course, run at full 2200RPM speed with no PWM control if powered up this way.

Pros: seems well built. Moves a good amount of air. EVGA is a great brand name. If you need 140mm fans to push alot of air and don't mind the high rpm noise, these aren't bad at all. great for a mining rig.

Cons: gets loud if you push these past 1300 rpms. not a huge fan of how they have you rubber isolate the mounting points, but meh, it works.

Overall Review: I love me some EVGA, and I would recommend these fans given their normal day to day operating speeds, the fans are quiet. If I push these to 1500 rpm's and higher, they get noisy. It is what it is, a fantastic fan at normal everyday operating speeds.
