The R4 fans have a lot of hype and therefore a lot of questions. They are rated at 2000 RPM/90 CFM/19 DBA I recently received five of these, two with no LEDs and three with blue LEDs. I'd like to share my experience with them.

To start, the external build quality is surprisingly cheap. I guess this is why the price is only $7-$10. I suppose these were built just for performance. Let me tell you, that is very true. When installed, these things push a LOT of air. They spin at 1900-1950 RPM (vs the Antec TriCools which spin at 1850-1900, both are rated at 2000 RPM) according to my fan controller that I recently sold. I run all of my fans at max speed. At max speed, these fans are surprisingly quiet. They really aren't that much louder than the 1200 RPM 120mm fans that CM includes with their cases! By the way, those fans actually only spin at around 1100 RPM according to my fan controller.

I use the COOLER MASTER ATCS 840 case (best overall tower case in my opinion), which really quiets things down. Before these fans, the only audible things were the Antec TriCool fans (two) and an 80mm fan. I replaced the 80mm fan and one of the Antec TriCool fans with the CM R4 series fans, and the sound went down a lot. With my head being only about 1.5 feet away from one of the R4 series fans (in my Scythe Kama Bay), I cannot hear it. With my ear right up close, I mainly hear the Antec TriCool fan which is inside the case! They push more air than any other 120mm fan I used, including the 2500 RPM iBuyPower fan which was incredibly loud and only rated at 80 CFM. Overall I am very impressed by the performance of these fans. Even though the build quality is kind of cheap, they perform incredibly well at very low noise levels.

Here are some pictures of them.

The non-LED and LED versions all look the same. There are nine blades, each one having a smoked look and are somewhat transparent. Here are the first two I received yesterday, non LED versions. One is in my Scythe Kama Bay, the other is in the external air duct that came with my ATCS 840.

The two dark fans are the CM R4 series. The other three are Antec TriCool (the highest bright one), and two Yate Loons. I will replace these with blue LED CM R4 series fans very shortly.

I replaced the modded 80mm fan with a blue LED CM R4 series fan, which you can see in the above picture as well. What you can't see is that I replaced the rear fan with one of the blue LED R4 series fans as well. The external air duct has a non-LED R4 series fan.

Scythe Kama Bay has a non-LED version.

My GTX 260 now idles at 40 degrees, compared to 43-45 before I added these fans.

I will recommend these fans to anyone who wants both performance and silence. I don't know of any other fan that performs this well with such little noise. I will probably get some rubber grommets to further reduce noise, not that they need it. Soon all of my 120mm fans will be CM R4 series, the three blue LED fans that aren't the R4 series will be soon. When I get my Prolimatech Megahalems next week, I'll be using two Scythe Slipstream 120mm fans which have a 1900 RPM/110 CFM rating, but are loud at 37 CFM and supposedly have a short lifespan without instant lube. If they do die shortly I'll use some of these R4 series fans, 90 CFM is more than adequate anyway.

EDIT 06/13/09: Got my Megahalems :gnd:

1-3 degrees cooler idle, around 10 degrees cooler under load compared to my old water cooler!
