Cougar TURBINE CFT14S4 140mm Case Fan

Pros: Move a lot of air, they are quiet and frankly thats all that matters for fans.

Cons: None they are great

Overall Review: Make sure you have 140mm fan slots in your case first! I did a dumb and got them and only have 2 140mm slots in my case the other two were 120mm so just make sure you have 140mm slots first! Still amazing fans for the cost and quantity.

Pros: -You'd normally have to spend $60+ to get this many fans, and they'd probably be a lot worse than these. -Build quality is great. Fan frames and blades feel solid, and the included molex adapters don't have flimsy/misaligned pins. -Maybe orange isn't your color, but I just can't get over how cool it is that I can buy a multi-pack like this without having to settle for boring black.

Cons: -They're quiet, but not silent. All four of them going kinda sounds like I'm running a small generator. -If you're the kind of person who'd look a gift horse in the mouth, you'd probably also like some LEDs up in these fans.

Overall Review: If you've just bought a large-ish case with lots of fan mounts and want to get it properly ventilated, this one purchase will probably get you to your goal. If you just want to keep a few spare fans on hand for the future, this is really the way to go.

Pros: The part is you can buy 4 at time and seem be running very good far

Cons: Nothing to report

Pros: These were extremely cheap and for the first year they were very quiet.

Cons: They're now very loud and whiny. Even through cleaning my computer regularly they still got pretty loud.

Overall Review: If you don't mind noise later on, you'll probably be fine. They are thankfully cheap enough to excuse the noise.

Pros: April 2018: I bought these on a recommendation from another user and I'm a believer in the product. They're quiet and move air without fanning it out. Replaced four Corsair fans. Keeps everything cool like a boss. February 2022: I'm planning my new computer. I will again add these fans.

Cons: None!

Overall Review: They sorta looked cheap but that changed in a hurry. Worth every penny. I'm buying more.
