    Depending on the AIO its design will limit far more. As Lenny says, something like the TRUE 120 scales far better than an AIP as heapipes cunduct the heat far better than watercoolers do, and if you increase the delta T they work better! So better fans would show better cooling far more, the TRUE always showed this. :)

    I get that but “better cooling” was not the intention of the test. I fact if you use a less efficient cooling method then you should expect to see a bigger difference in water temp between the best fans vs worst fans.

    The idea of the test (at least in my head) is to compare the fans "cooling ability" against each other. This should be easier if you have a bigger range of possible temperatures that you can accurately measure.

    My thoughts were that some of the fans on test are so good, they wouldn’t have much between them all so with margins of error, would in effect be equal.

    Not if the cooler starts acting like a insulator. You need something that will be as open as possible with as high a cieling as possible :)

    Sweet - I've always wanted to test that Silverstone fan as it's the "only" 140mm fan in 38mm flavour. Bit pricey for my liking, but I'm sure I'll end up getting it one day.

    Meanwhile, I made a quick vid of the GFC just for the lolz. The other fan is an absolute monster in its own right, weighing in at 405g. Maybe now it's clear why I'm scared of this fan!

    Just saw this and I knew exactly who'd be interested!

    @Bloody_Pete, yeah I've been following his stuff. Some of his ideas are pretty cool, but often it's "silly science" which isn't always my thing.

    Today I got 120mm fan goodies in the post from @Vault-Tec (thank you kindly!) and will be testing these this week. I've always been keen to see just how effective these Corsair fans are, and I guess we'll find out soon. Also, the eLoop is just a beautiful fan - it just oozes quality.

    I should really dig out some of the fans I have for you! I have some OG GT's, that 1850rpm perfect ones, before they got some acustic weirdness. They're the ones everyone things of when they think GT's! I also have some I painted, so it'd be interesting to see how paint affects them!

    Dope dude ! can't wait to see the results :D

    I was always told the Cougar were the best of the time, and they are very strong fans but yeah no data lol.

    I bought five boxes of those extensions, then realised the sodding Eloops come with it all in the box lmfao.

    Haha yea, the eLoops have a lot of accessories with them.

    I had a bit of time this evening to do some thermal testing with the fans, and I'm pretty surprised by the results. I tested the Noiseblocker eLoop, Corsair SP120, and the Cougar Vortex. Performance-wise on the heatsink, they are all within half a degree of each other.

    I re-tested the Noctua A12x25 because I was using that as my baseline in the last round of testing, and each other fan beat it by over half a degree. I'm not convinced that there's any significance in that, but make of it what you will. One thing worth noting is that the Noctua is just ludicrously quiet compared to all the others. Even the eLoop, which I like a lot, had an irritating hum when running on the heatsink. The Cougar was very good.

    Delta temps
    Noiseblocker eLoop: 32.3°C
    Corsair SP120: 32.2°C
    Cougar Vortex: 32.3°C
    Noctual NF-A12x25: 33°C

    As for maximum static pressure, the Corsair SP120 stomped all over the others with a pretty mad 4.7mmH2O, but it's a 2,350rpm fan and may as well be a Delta at that speed. Both the Cougar and the eLoop were a fraction below spec.

    I'll do a round of tests with the sound level meter when I get some time and some peace - it's been raining all day and it's so frickin' loud, plus the seagulls won't shut up. Kids are away on holiday for the next two days so I'll have plenty time to mess around with fans!

    I'm surprised I must say. Then again I'm not totally surprised. It's been known for years that Corsair's SP fans are very, very good (that's why they still use them on non RGB coolers). The others? again, were rated as the best or among the best when tested (and that Cougar is about 10 years old now !).

    Good to see how they really perform though ! I've never ran the NBs at anything even resembling full speed. In fact, I don't think I have ever run a fan at over 7v.

    I did some sound level testing with the eLoop and the Cougar, but I made a mistake with the video so I'm going to have to re-shoot it... that's what I get for doing it late at night when I'm tired and can't concentrate!

    I'll be recording again this evening and will hopefully have something to share shortly thereafter.
