Need advice for 140mm fans with good static pressure

post #1 of 28
Thread Starter 
Hello,

Sooner or later, I plan on upgrading my EK Coolstream XT360 (With 6 AP-15's on push/pull) for an Alphacool Nexxxos UT60 420mm (With 6 140mm fans on p/p). The problem is I was recommended some "Bgears" fans but those are not sold in Europe (At least I can't find them).

I was thinking of going with the Corsair AF140 fans, but those have very poor static pressure as they're meant to be a case fans and not heatsink/rad fans.

Any recommendation for good 140mm fans for water cooling that are sold in Europe? I was really hoping Corsair had some SP-140 fans (Like the SP-120) but apparently those don't exist, yet. tongue.gif

Got a 6 fan controller? You'll need one. But these fans will solve your problem handily: SILVERSTONE FHP-141 http://www.newegg.com/Product/Product.aspx?Item=N82E16835220056

I think you forgot where I mentioned the fans needed to be available in Europe. tongue.gif

I do have two fan controllers, for a total of 8 fans, so that wouldn't be a problem, but not sure those would be the kind I'm looking for.

If you don't mind spending cash for some awesome radiator 140mm fans...Here are your choices...

Noctua NF-A14 FLX / Noctua NF-A14 ULN or if your case allows room... Noctua NF-A15 PWM

Here are a couple of reviews...

What's the difference between those two except for the 2nd one being slightly bigger? Also, what's the static pressure on those? Caseking doesn't list it.

And any idea how those would compare to these Akasa Viper? http://www.caseking.de/shop/catalog/Fans/140mm-Fans/Akasa-Viper-PWM-Luefter-gelb-140mm::17540.html

They're listed with a static pressure of "max. 3,12 mm H2O" which seems crazy good!!

Looks like the NF-A14 FLX is rated at around 1,51mm H2O, wondering if the Akasa Viper are overrated or they're actually much better than the Noctua for radiators for half the price?

Hahaha...Great find thumb.gif That was the next fan I was about to list. The Akasa has 2 times more static pressure than the Noctua fans I had listed. The Noctuas are listed @ 1.51mm H20 but you can't beat the silence factor with those fans. If you don't mind a little noise but prefer a lot of static pressure, definitely buy the Akasa Viper over the Noctua fan biggrin.gif

Looks like the Akasa Viper have actually even higher static pressure than the current Gentle Typhoon 1850RPM fans that I'm using.

Honestly, I can live with my AP-15 fans as high as 1500RPM, they don't bother me for sleeping, so as long as they're same or quieter than the AP-15's, I'll be happy, although It would be interesting to see if I actually need double the static pressure coming from the Noctua to the Akasa Viper for using an Alphacool Nexxos UT60 420mm or Phobya G-Changer 420 V2? I heard those have very low restriction, so I'm not too sure wether the extra static pressure from the Akasa would help or should I stick to the Noctua.

I'll say this...Overall quality will be Noctua regarding noise & static pressure. The Viper fan is a great performing fan but Noctua's fan design is what makes the difference. If the Akasa Viper is a better radiator fan, I will not be surprise if not be far. And you are thinking correctly that just because the fan has a high static pressure rating does not mean it's simply better. Noctua has an excellent record with their fan designs holding true to their performance. If you ask me which fans I would buy, I'll go with the Noctuas over Akasa. I've owned fans that did not hold true to the static pressure spec but Noctua is well known for their consistency of improving the fan design with the "so-called" low static pressure spec. That's why you can not ignore how important the overall design of the fan plays a major factor.
Did you read the reviews for those Noctua fans I had listed in post # 4?

Good thing you reminded me about those reviews, I did not see them.

I'm leaning more towards the Noctua indeed, now it's matter of deciding wether or not I actually need push/pull, as they cost a lot, but I'll probably go with 6 for push/pull hehe.

I just wish Corsair made some SP-140 fans like their SP-120, those are very nice, specially the Quiet editions. smile.gif

I guess I'll just go with the Noctua, unless Corsair decides to release some SP-140 by the time I order the fans and radiator in a month or so.
