5 out of 5 eggsIts a fan

This review is from: Cooler Master Blade Master 80 - Sleeve Bearing 80mm PWM Cooling Fan for Computer Cases and CPU Coolers

Pros: Doesn't click or whine or vibrate unnecessarily and PWM control means it remain quiet at low RPMs until more air flow is required for additional cooling effect.

Cons: None.

Other Thoughts: Its a fan. Marketing pitches abound where fan are concerned. I was a sucker for the hype for awhile but this is the bottom line: there are no free-lunches. We all want that magic fan that provides gobs of air flow while remaining whisper quiet... but the reality is you can't cheat the laws of physics. Greater air flow means faster RPMs which result in greater noise generation. There are no miracle designs or break-through in technology that will bend those laws... all you can hope for is a fan with a motor that doesn't whine, or have annoying frequency harmonics, or clicks due to defects in manufacturing. And in the case of a sleeve-bearing fan... DON'T MOUNT IT HORIZONTALLY, it will fail within weeks or months. This SLEEVE BEARING fan has none of those issues and is priced reasonably anything more for a fan is a rip-off.

2 out of 5 eggsonly lasts about a year

This review is from: Cooler Master Blade Master 80 - Sleeve Bearing 80mm PWM Cooling Fan for Computer Cases and CPU Coolers

Pros: cheap

Cons: It's ready to be scrapped after 15 months. The bearing is going out and it sounds aweful.

Manufacturer Response:

Dear Customer,

We are sorry to hear what happened to the fan. We can definitely help in replacing that fan under warranty. To ensure fans live their rated life, it is imperative that they are cleaned regularly as dust that is not cleaned, can definitely cause a fan to fail. If you have further questions, please let us know.

Respectfully,


CMUSA Support

5 out of 5 eggsDoes it's job

This review is from: Cooler Master Blade Master 80 - Sleeve Bearing 80mm PWM Cooling Fan for Computer Cases and CPU Coolers

Pros: Cheap 4 wire CPU fan that does it's job.

Cons: Had to drill out the mounting holes on one side so I could get a screwdriver in to tighten the screws to the heat sink. It's plastic so no big deal.

5 out of 5 eggsnot loud at all

This review is from: Cooler Master Blade Master 80 - Sleeve Bearing 80mm PWM Cooling Fan for Computer Cases and CPU Coolers

Pros: Installed a pair of these in my Silverstone GD09 case. They come with rubber spacers and make no noise I can hear. They push a decent amount of air for the size. I'm using them as exhaust fans in rear of case.

Cons: A lil pricey at $10 each.

5 out of 5 eggscpu fan

This review is from: Cooler Master Blade Master 80 - Sleeve Bearing 80mm PWM Cooling Fan for Computer Cases and CPU Coolers

Pros: the fan is exactly the same as the fan that comes stock on the coolermaster hyper 101, perfect for push pull airflow

Cons: none that i can see yet, is fairly quiet

Other Thoughts: slightly overpriced when i bought it but it was still worth it to get the exact same fan as on my cooler for ideal air flow

5 out of 5 eggs

This review is from: Cooler Master Blade Master 80 - Sleeve Bearing 80mm PWM Cooling Fan for Computer Cases and CPU Coolers

Pros: 3000rpm 80 mm fan
4 pin pwm
great static pressure
fairly quite at max speed

Cons: sleeve bearing... wish it was either ball or fluid/rifle

Other Thoughts: Even though its sleeve it should last at least four and a half years at max rpm running 24/7.

bought two of these along with a 4 pin pwm splitter to cool my vrms heatsink and north bridge on my asus m5a99x evo r2 motherboard. They do a fantastic job at keeping it cool. They're also long enough that to cover all the way up to my water block on my 8350 and help cool the socket as well.

I highly recommend these fans. One of the few 80mm that are both high rpm and 4 pin pwm.
