Pros: first ordered these for the case that I was intending to put into, these were to big. then went to a size smaller than these.

Cons: No cons the fans started right up just testing these.

Other Thoughts: Measure the fan mounting holes in the case before you order them. this will save you loads of trouble. After all New egg rocks :D

Pros: - Very Silent even when cranked to max via fan controller.
- Leds aren't extremely bright nice deep color
- Moves lots of air

Cons: Non at the moment will update if anything happens.

Other Thoughts: - 1 of the fans I purchased came with a 1 dead led only reason for the 4 star as apposed to 5. (it didnt really bother me since the remaining lights are effective enough to still give my system a nice glow effect/look)

Pros: -- The blue LEDs look really great
-- Airflow is outstanding; I have these spinning at a static 1200RPM pushing hot air out with three other 120mm fans pulling cool air in and my internal case temps stay low even with everything under high load
-- Very quiet (I sit right next to my rig and hear my single 120mm case fan over these two 140mm fans spinning at max RPM)

Cons: -- Had these for only a year and they are now both beginning to rattle bad randomly from the center bearing; I tried loosening and tightening their mounts to no avail - the FDB bearing is supposed to prevent this from happening so quickly so I'm not sure what happened

Other Thoughts: I bought 2 of these about a year ago to mount to the top of my case in a push configuration to push hot air out. If the rattling gets worse I will have to buy a set of new case fans only a year after I purchased these :(

Pros: + The pre-installed one similar to it blows air fairly well
+ Quiet enough for the price
+ Price

Cons: - Poor quality screws
- Potential nightmare to install
- If you screw up the installation, the fan could be pretty much useless
- Probably a good idea to find an alternative to screws in installing it

Other Thoughts: Seems like it might be a good fan. It's disappointing to have to give it 3 stars however, since I can't seem to verify that for myself after the nightmare I had attempting to install it.

The screws that came with it strip incredibly easily, and had to be removed with pliers the first time.

Second attempt was with case screws that were purchased seperately, and ended with a screw so well stuck in the fan (but not in far enough) that had to be removed with a small hacksaw.

Now I have a useless fan, with part of a screw stuck in, lodged so well that it won't come out using anything, minus maybe a metal rod and a hammer.

At this point though, I don't particularly care to even try again. The mounting holes on this are just horrendously designed. Installing the fan should not be that difficult, or else some other mounting option should be included.

I'll look for an additional fan elsewhere, sorry Rosewill.

Pros: Silent, blue, looks very nice.

Cons: The screws that came with the two fans I bought were horrible and actually appeared to be too long. I could not use them, even when mounting these on a Rosewill Blackhawk case. I had to resort to fan screws from my PC graveyard to properly tighten the fans to the case.

Other Thoughts: Order a small amount of fan screws if you get these. Maybe I just got an odd batch.

Pros: Blue LED, ideal brightness at low voltage
Decent airflow, only needed to run this at lower speeds

Cons: Is loud at max speed, you probably don't want to use this directly plugged to the PSU unless you don't care about the sound of a fan, which doesn't sound bad.
Pretty bright at full power too, since they're controlled together with this 3-pin fan.

Other Thoughts: Not much to say

Pros: It is an average fan for an excellent price.

Cons: Seems about as loud as my CM 80mm LED cheap fans.

Other Thoughts: Its color is a bit more violet than the typical bright electric blue that most other components. It's not a deal breaker, but I notice it when I look at my system.

Pros: Moves a good amount of air, Air flow at full speed is not noisey.

Cons: Motor whines and is louder than I would like to hear without hearing aids. I would guess it at about 32dba.

Other Thoughts: Maybe I just got a bad one.

Pros: This fan blows air. I suppose if it didn't, it would not be much of a fan. It is also pretty quiet. I run it at full speed all the time and do not notice much of a difference from the rest of the fans in my system. Looks great, bright blue LEDs.

Cons: None.

Pros: Quiet and moves a decent amount of air. Temps dropped a couple of degrees from the 120mm fans they replaced. Good buy. Got four of them on sale and with promo code. Come with molex adapter if you need it.

Cons: None so far.
