When I contacted the Rosewill rep about sending fans for review she was a bit hesitant, but I wasn't convinced there wasn't something good hiding out in their lineup. Rosewill often provides good products at reasonable prices, so I felt like their lines were worth investigating. I received this fan, which is actually a PWM fan (despite having virtually no dynamic ratings), and the next one...

| 87.5 | none given | 2200 | 38.15 |
The other Rosewill representative is a more basic, garden variety case fan with no qualms about running full tilt. It bears mentioning that this model does include an additional fan controller bracket that may make it at least a little more attractive (though personally I'm more interested in the fan controller bracket than the fan), but this should at least be a good representation of a generic case fan.

| 50.5 | 1.63 | 1500 | 15.7 |
The Silent Wings 2 is be quiet!'s top of the line fan. While our rep (who amusingly enough is my predecessor here for case reviews) wasn't super bullish on it as a radiator fan, the staggeringly low decibel rating and decent airflow and static pressure at least make the Silent Wings 2 a compelling entrant worth checking out. be quiet! as a company has been slowly making waves lately so I've been anxious to test some of their products.
be quiet! is still young yet and like BitFenix they're very slowly making inroads in American markets. As a result the Silent Wings 2 isn't widely available yet, but a quick visit to Google Shopping can find the Silent Wings 2 for a healthy $40.

Add me to the list of users baffled by the omission of GentleTyphoon fans from the testing. This is like excluding a Jeep Wrangler from an off roader comparison.scook9 - Monday, October 22, 2012 - link
When I switched to water cooling, like any other good geek, I did an obsessive amount of research and reading online to find the best solution. Time and time again, I ended up with the same recommendation - the Scythe Gentle Typhoon 1850 rpm (AP-15) model. I have about 10 of these in my house now and use them on everything (HTPC, server, desktop, laptop cooler). They are expensive fans but they will also last a LONG time while performing very well.You may not need to do a 3rd roundup, just a 1 page one-off for this fan to satisfy the masses :D

Dustin,I can't be bothered to chek all the fans but, at least in the case of the Scyte Slipstream and Nexus RealSilent, those are case fans, not CPU fans. It's pointless to include them in this test.
And I second others in stating that if you're interested in sufficently powerful yet almost silent CPU fans, you may want to check the Gentle Typhoon and Noiseblocker.

This exactly. After doing much research earlier this year I bought 2x gentle typhoon's and 2x Noiseblocker NB-Multiframe M12-P fans to add to my collection of Noctua's and other fans such as the excellent TR-TY140's.
After testing all of them the M12-P's stayed on my overclocked i7-3820 doing push/pull on a TRUE 120 heatsink. They are the business, quiet and powerful. Gentle typhoon's ran a close 2nd and are great fans also.
The fact that you don't include two of the best fans around for heatsink use seems odd to me. Looking forward to part 3 =)

"Corsair's solutions"Really? It's a fan. Reconsider your use of the word "solution" as a replacement for everything. Sometimes it makes sense, but often it's just a silly fad word that has gotten out of control.

hen you are writing a longer text, it is considered good form to occasionally replace often-repeating words with substitutions to improve the reading flow. If every sentence had the word "fan" in it, you'd eventually get dizzy. It's like starting every sentence in a story with "Then", that's just a no-go.Hulk - Monday, October 22, 2012 - link
I think it would be helpful to isolate fan performance.When reviewing cooling fans how about connecting each fan to be tested to a variable speed controller and set the speed of the fan to a predetermined cfm so that the fans can be evaluated on a level playing field. This way noise can be evaluated in an even playing field.
In the same manner speed can be increased/decreased to a predefined level and cfm and be measured.
Because in the end what we're really trying to determine is which fan moves the most air while being the most quiet while doing it.
Or, if you won't want to deal with cfm measurements, just load the test bed and increase/decrease the fan speed until the temperature is at a predetermined level. Then measure the noise.

No mention that CoolerMaster's Turbine is based on the compressor section of a turbofan jet engine? Hmm.nianiania - Monday, October 22, 2012 - link
You're testing the cooling capacity of fans for a radiator, in an environment this type of solution WILL NEVER BE USED IN. Broken right from the start. If someone's investing 60-120$ in a water cooler, the chances they're building an HTPC without a graphics card in the system are slim to none.This should have at least a 650 or 660 in the box to get a more real-world result. It's not often you let us down Anandtech, but this one is a pretty obvious failing on your part.

I would quite like to know how many amps each of the fans actually draw, as it has been my experience that the spec sheets frequently list a value that is not accurate. In future reviews/round ups, would it be possible to measure and list the actual amps drawn please?
