200/220mm fans for rads ( Phobya 1260 )

post #1 of 4
Thread Starter 
Hi guys I'm gonna build a system ( first time ever ) it will primarily be used for hardcore gaming, running VM's and a bit of video editing, and maybe a bit of benchmarking.
What I want to watercool is :

- an overclocked 4670k ( but later that may be a higher-end cpu )
- two overclocked gtx 880's, that's for later obviously
- maybe one or two mobo blocks too ( for now it's a Maximus VI Gene )
- and maybe my psu too ( a Super Flower Leadex 1300W gold )

There will be two pumps and the case will be the Phantom 410 mid-tower case heart.gif

I want to be able to push wild overclocks ( if chips agree ) and remain as cool as possible, while keeping my fans at low rpm to keep them as quiet as possible... that's why I decided to go with the Phobya Xtreme SuperNova 1260 external radiator, which can handle that heat silently ( and which seems to be more suited for low rpm fans than the MO-RA3 ). Its size : 460 x 420 x 46 mm.

It can be mounted with 9x 140mm-fans or 4x 200/220mm-fans, and I've decided to go with the latter since I'm aiming for low rpm.

Now.. I find it pretty hard to gather info about big fans mounted on rads, and the few tests I've stumbled upon are a bit outdated ( 2009-2011 ).
All the tests of the Phobya 1260 I could find have it mounted with 4x 200mm Cooler Master MegaFlow and 4x 220mm Yate Loon D22BL-12H.

So all in all, here is what I could come up with:

- Yate Loon D22SL-12H 220mm...600rpm ( not on a rad ): 61 cfm / 32.3 dB ( low static pressure )

- Yate Loon D22BL-12H 220mm...750rpm ( not on a rad ): 76 cfm / 35.3 dB ( low static pressure but it has proven it can get the job done fairly well on a Phobya 1260 ...but too noisily ? )

- Cooler Master MegaFlow 200mm, less performant than the D22BL-12H, but produces less noise ( both compared on the Phobya )

- Antec Big Boy 200mm..............600rpm ( not on a rad ): 47 cfm / 28.5 dB ( has good static pressure, at max speed of 900rpm it is too noisy at 37.4 dB )


And that's it.. I'm at a loss regarding what to choose or where to find more recent info. If you guys know about better fans than those for the job, or would pick one in particular among these, well.. I'm all ear ^_^

Oh, and I still don't know if it'd be better to go for a push or a pull config. I think there are fans that do better at pushing or at pulling, that may be something to take into account.

Thanks ! smile.gif

the only big fans worth a damn on rads are the silverstone air penetrator ap-182. they are 180mm fans.
for the difference in temps, i would just go with a 1080. there are definitely good fans made for it and its the equivalent of 3x 360 rads. it will also take 4 of those ap-182 fans thumb.gif
i know youre joking about water cooling your psu. that never gets old and is always funny as hell...

The rad will be the Phobya 1260 biggrin.gif ( and I've just bought that stand for it http://www.aquatuning.de/product_info.php/info/p12787_Phobya-Support-Radiateur---3-fois-Triple---3x140mm--Bench, but at a cheaper price than that hypocritesmiley.png )

Okay so everyone says that big fans will lack the static pressure needed for good rad cooling, but here http://www.effizienzgurus.de/review/wasserkuehlung/phobya-xtreme-supernova-1260-radiator/messergebnisse-temperaturen-durchfluss.html we see the Yate Loons 220mm do a good job ( the 1260 is low fpi and only 46mm thick, so static pressure may not be so important.. not really sure ). I did a graph on my own ( rpm / temps ) based on the results of that test, and the YL 140mm would even have to spin faster than the YL 220 to perform as well as them ( so even more air moved ( 9 fans instead of 4 ) + more air pressure ( them being 140mm instead of 220mm ) wouldn't be match for those bigger fans, in the case of the Yate Loons ). Low rpm matter to me as I seek quietness ( and the Phobya 1260 is more suited for low rpm ). So for now I was going to get the 4x YL 220.

But my reasonings may be inaccurate and there may be other 140mm fans that would do better than the YL 220mm *at the same rpm*, or as good at lower rpm ( theoretically 9x good 140mm-fans will overall move more air than 4x 220, with a better static pressure... that's why I'm a bit confused about the YL 140 being beaten by the 220 at a given rpm ). That's why I'm hesitating between 9x140mm ( don't know which ones ) and the 4x YL 220.
And maybe I'll do a push/pull config if that's not too noisy.

Yeah, so aiming for the best performance and quietness. I've also tried to take into account that larger fans have larger blades, move more air, and all that has an influence over noise.

Well.. I've considered going push/pull, and that can be done for a reasonable price with bigger fans... 18x 140's just cost too much.

So I think it's right to say that between 8x 220 in push/pull and 9x good 140 in push, the former will perform best, right? Someone could confirm this please ? (..and it wouldn't be more expensive, 9x Helix 140 would even cost as much as 8x YL 220, where I can get them )

So if that statement is true, the 8x Yate Loon D22BL-12H 220mm will be the way I'll go.
