...CoolerMaster Sickleflow 120 2000rpm fans?

The stats on the box/website seem to indicate they are good. Quiet, good airflow, good static pressure...

I realise the stats may not be 100% accurate, but you have to base a choice on something right?

So has anyone tried them?
Are they good as case fans?
Are they good as radiator/heatsink fans?

If they are good, why are they so cheap?
 
Cant say ive ever heard of them, but as for being cheap i wouldnt neccesarily let that put me off, some of the best fans ive ever used cost 4 or 5 quid each, yate loon's and arctic f12's.

Link should be fine yeah, cheers.

30Pa of pressure is very good indeed for a 2000rpm 25mm fan. Here's a sanyo fan that offers the same pressure at the same rpm.

If your coolermaster lives up to it's spec, it'll be good. You don't really want a 25mm fan on a radiator, but if you don't like gentle typhoons this seems a reasonable choice.

Good, honestly rated fans with LEDs are improbable though, so best of luck. I believe sanyo, but I don't think I believe coolermaster. Perhaps that's unreasonable.

p.s. the air flow and noise numbers are arbitrary, static pressure should be more reliable though it's anyones guess how well they measured it. If it's quiet I'll be astonished though, 4W is a lot of power for a 25mm fan to draw.

If you go for it please report back :)
 
4w does seem pretty high, iirc the sharkoon silent eagle 2000's i had on my old q6600 TRUE combo drew 2.16w.

I'm currently using Akasa Apaches, these just looked statistically better, although slightly louder.
I'm trying to cool an overclocked Phenom II X6 (1055T @ 3.8GHz) and a 4870x2 (currently @ stock) with 360mm of Radiator (well a 240mm and 120mm) so trying to optimise the rad cooling the best I can (In a CM 690 II case, so space is at a premium).
Was planning on running the bottom (120mm) rad with push/pull fans to get the most out of it. I don't believe there's room to do push/pull with the top rad.

Do the fans in a push/pull config need to be the same or can you use different models?

If not 25mm fans, what would you recommend?
 
Apaches are well specified (I'm somewhat biased against them for getting their rated static pressure out by a factor of ten then taking a terribly long time to rectify the rather flattering error, but that doesn't make the fans themselves bad). I don't think you'll get your moneys worth changing them for other fans though, and would actually expect the coolermasters to be slightly worse.

I'm using scythe s-flex for 25mm, but if buying new would go for gentle typhoons. It's not worth the upgrade until the s-flex die off though. I've also got a 38mm san ace which is a beast, and I'll likely buy more when they're readily available again. There is absolutely no comparison between the san ace fan and the scythes.

Matching fans is unlikely to matter, even two of the same model will spin at different speeds and experience different forces on either side of the radiator. I can see some sense to deliberately pairing a 1900rpm with a 1600rpm for the purpose, but I doubt it'll make a difference. Push-pull in general is only good for a couple of degrees or so in my experience anyway.

Shrouds are good though, use them if you possibly can. Fans screwed straight into a radiator perform worse and make more noise than when they're distanced slightly away.

I sympathise with limited space, my akasa isn't built for large radiators. Creativity will see you through :)
 
Push pull fans in theory should be better if they are matched but there are other factors that come into play. As for the fans, I have a couple and I like them. I don't know if they do flow as much air as they state but they do flow enough and I have to also say are quiet fans - though mine are cable tied into place not screwed as in normal use. I don't know how they would perform on a rad though either but I would expect them to do a reasonable job of it.
