This fan in particular was one I picked up some time ago on a recommendation from Silent PC Review. I was looking for a fan that delivered a good blend of performance and acoustics, and this looked to be it. As it turns out, the Slipstream has served me well for a fairly long time. It's barely inaudible but it does move a decent amount of air (I used a pair on a CoolerMaster Hyper 212+ heatsink). With my history on hand, I was curious to see if it really was as good as I thought.

This one's kind of an oddball. It's ratings are lowish and you can't find it in retail anymore, but it saw inclusion in a lot of different cases over the years. It wouldn't be surprising if some enthusiasts had one or two laying around. Since I had one, I figured I'd test it too.

Antec's TwoCool 120 isn't readily available in retail on its own, but is included with the popular P280 enclosure as well as a few other models. I was actually using a pair of these briefly to cool a 240mm radiator. If you have an Antec case that uses these, it may be worth seeing if they're a decent alternative to the stock fans that come with your radiator or cooler.

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?
