Pros: No off-center decal sticker on the hub... I guess CM knows how bad it is and doesn't want the recognition for it...

Cons: Very low RPM, airflow, and pressure, all while being very audible. Not due to turbulence from the impeller, but because there's an audible hum from the motor. Top that off with not having a pass-through header for the RGB; it's an end-point in the RGB chain. There's only 4 RGB lights in it with enough separation between the colors that you can distinguish the colors, so forget about white, yellow, orange, purple, pink, turquoise, or cyan. You'll see the individual red/green/blue that makes those colors. Oh and the frame isn't a flat square. This leaves massive air gaps around the frame causing back-flow and drastically reducing what little pressure it already has. Performance-wise there are better pressure fans for $5; a fifth the price.

Overall Review: So... what's going on CM? Your QC is pretty bad in 2017... Care to step it up? Like... to a professional minimum?

Pros: -Price

Cons: -International shipping takes long (20 days) -Package arrived unboxed

Overall Review: -My fault ordering international. Just takes to long to get to the States. -Would of paid more to insure there would be retail packaging.

Pros: - Quiet - Good price for a PWM RGB fan - matched up well with the Silverstone PWM fan hub Connected 3 of these up to my MSI x370 Gaming Pro Carbon motherboard using 1 fan header and the silverstone PWM hub. also used a 4 connection RGB splitter to get the 3 fans and 2 strip lights all sync'd up and running of the 1 RGB header the board has. All works with Mystic light and fan control is through the BIOS settings on the header. Fans are quiet, no issues with noise at all in my corsair 270R case. Been running them for a few weeks now once I got them all wired and set up the way I wanted.

Cons: - when used as front intake the lighting is dimmer (base on LED locations) Not so much of a 'con do not buy', but be aware that these are dimmer than some, and since for intake at the front it means the back of the fan is facing into the case, the light is directed more towards the front of the case than in. Still ok for me, but just so people know...

Overall Review: recommended RGB fan for sure.

Pros: Only thing I can think of would be the build quality. They feel sturdy.

Cons: I bought 5 of these. At maximum speed, they make a slight high pitch whine that becomes annoying after a while. 1 of them will start rattling excessively after 5-10 minutes and will rattle and stop ongoing. Another will rattle every time I tap or drop something on the desk.

Overall Review: It's important to know that the power for the LEDs comes from the PWM connector, NOT the RGB connector. Thus, at lower fan speed, the brightness is much less then pictured. So if you're buying these only for the RGB, you'll be disappointed... who wants to run their fans at max speed just for the perfect illumination, but get their nerves grated by the noise?

Pros: - Look pretty good - Seem to be built really well

Cons: - Absolutely the worst performing fans Ive ever used. No way these should be used in any static pressure application - RGB colors seem to be not that good (closest youll get to white is a yellowish color)

Overall Review: - I bought these with the CoolerMaster controller. The fans are easy to setup and use through software, and they really do look amazing. They just have TERRIBLE performance

Pros: -RGB -sync with asus aura

Cons: -Bad performance 10 degree rise from my Corsair HD120 -Terrible vibration sound from 2 fan of 3

Overall Review: I bought 3 of those and 3 air flow. Can't beleive that i will lost mu shipping cost cuz cooler master can't make a decent RGB fan. The air pressure of those fan are a lie. Thanks again cooler master for this great product.

Pros: - First RGB fan to be controlled by motherboard software - Silent - Pushes a decent amount of air compared to the noise level - Cheaper than other RGB fans that require expensive controllers

Cons: - Could have been slightly higher RPM's to push more air

Overall Review: This fan looks and performs incredibly. I have had no issues with noise whatsoever. In fact, it is so quiet that even at 100%, I can't hear it over my case fans that are rated for 22dba. Honestly, this thing is so quiet, that they could have increased the RPM to push more air and had roughly the same acoustics. As long as you have a compatible motherboard that can control these fans, I wouldn't hesitate buying them. Keep in mind though, I've heard that each of these fans needs its own RGB connector to function. I was not able to test this myself since I only have one, but it's something to keep in mind if you plan on buying a few of them.

Pros: I bought two and put them on my cooler in push/pull configuration. The ones I received are very quiet when the switch is set to S or Q. It moves a lot of air when set to P.

Cons: It took a long time for them to arrive from China and the fans were just wrapped in bubble wrap and stuffed in a big paper envelope. What I received from the seller looks very similar but the blades are a dark frosted color instead of clear frosted and there doesn't seem to be any lighting at all. The directions say there are 3 modes, R for red, B for blue, and RGB for RGB. The three position switch on the back of my fans is labeled instead with P, Q, and S. Changing the switch position seems to affect the RPM range as "S" is like baby's breath at 100% and "P" actually moves some significant air at 100%.

Overall Review: I wish I could write a review for the RGB Pressure fans but apparently the seller sent me the non-lighted version of the same design. I'm not sure how many eggs they deserve since the fans aren't bad, they just aren't what I ordered.
