Pros: I bought two more for my Define S case to match the two included. They are a nice balance between SP and HF fans.

Cons: Decent price.

Pros: Purchased two additional fans to go into a Fractal Define R5 to complement the included two. All I can hear is the air moving and my CPU fan even when ramped to max with the case's controller.

Cons: White blades I guess, but again I used the R5 so minus the one in the back that I can see through the window whatever.

Other Thoughts: Above con is irrelevant. Air flow certainly seems good, with absolute minimal noise for a fan. Worth the money.

Pros: - Matches the ones in my define s.
- Excellent airflow.

Cons: - None so far.

Other Thoughts: - These are not completely silent, but are low noise enough that i cannot hear it with ambient noise.

Pros: dose job as a quiet fan

Cons: the rpm on this fan is rated 1000 rpm but none of my 3 reach it they run at 870, 900, and 920 on full power

Pros: I bought these for my new Fractal Design S case. The case came with two of these installed and thus I purchased two more for three in the front and one in the rear. The frames are sturdy and the cabling is mesh sleeved. Nice. Overall with four fans running, I cannot hear a thing. :)

Cons: None

Other Thoughts: Overall a great fan that works great.

Pros: Good Airflow and decently quiet

Cons: Screws are a nightmare to use. Uses self tapping screws to go into fan holes that are not prethreaded. Also the screws are made of low quality metal and if you try to use a small screw driver you will strip the screws

Pros: Matches the case fans in the Fractal Design R5 case perfectly. Appears to work fine.

Cons: No cons so far!

Other Thoughts: If you are looking to get more case fans for your Fractal Design R5 case, I can confirm this one matches the included front intake fan perfectly.

Pros: -Everything

Cons: -Not wireless

Other Thoughts: -Just buy it... especially if you have a Fractal Design Case (they match perfectly).

Pros: over priced

Cons: These fans were slightly weaker than the r2 silent fans and it feels like it pushes less air out.

Pros: There quiet
Easy to install
Matches my case....well duh (Fractal Design Define R5 Windowed)

Cons: It's a 3-Pin fan....not much of a con though.

Other Thoughts: They run at full RPM's all the time....I have mine hooked up to a PWM fan hub and I'm not able to adjust to fan speeds. But my fan hub only allows speed adjustments with 4-pin fans. Cant blame the fan for that.
