140mm fan question

[p2501]

Can anyone recommend me some 140mm fans for HWLabs GTX-type rads? I understand I'd need some high pressure fans but it would be nice though if I could undervolt them, don't want to go deaf. As point of reference, I don't feel that 2k rpm Ultra Kaze's are loud.

[van_arnam]

there's tons of good fans out there (140 by 38mm, 140 by 51mm by delta and san ace). The problem i see is that all of them cost a fortune (newark has em for 80-120 a fan).

this is what's keeping me from going to 140. i would figure the shops selling the gtx 140.x series would have a higher CFM fan than the yate loon high speed 140 by 25...

[van_arnam]

57dB, 286 CFM. undervolted and near 50dB you could probably still get 200cfm. godly. but a grand to outfit 1 gtx 560.

50dB is still acceptable? :/
BTW, has anyone ever tried Yate Loon D14B(L|M|H)-12 fans? At least vendor published similar performance/noise ratings for them as for S(L|M|H) ones with sleeve bearing. I've seen these ball bearing ones used in few PSUs. I wonder how they would do on rads?

[p2501]

The rad in question happens to be a GTX560, so those San Aces are just a bit too expensive..... 0_o;

I'm currently looking for fans for a sr-1 420 (low fpi compared to your gtx) and found this round up in german. Hope it helps

IMO, 140mm rads and fans are too immature to be worth the effort ATM. Without any real testing done on the fans yet, all we have to go by is what reputation a vendor has in the "common" sized fan market. Of those, YL's are about the only fans worth getting that aren't insanely loud or outrageously over priced. . .and for a GTX560, about your only choice would be the SH 140mm YL based on performance on rad, price and noise.

Yates. Well, the rad is going to be mounted horizontally and I don't know where I read that but I thought Yates die even faster this way. I have 6 Yates running 24/7 for a year now and at least 3 of them have damaged bearings, they don't really sound too good. So my resolve was never to buy sleeve bearing fans again. Is there really no San Ace that is actually affordable?

To explain things, I'm currently running two PA120.3 with 1600rmp yates on a CPU/MB only loop (MB because the VRM on these DFI boards run reeeeally hot). I want to add two GTX480's and that's why I thought a 560 rad should propably be enough rad (I'm all for overrad, keeps things cool without much noise). I could just add a 480 rad, fan choice would be better, but what's the difference in capacity here?

your forgetting about the feser fans they are pretty reasonable in price

[affiliate13]

Feser dont appear to make 140mm fans do they? But yes if they did it would be silly money.

I am putting together some parts atm for a GTX560 and so far only the YL D14SH / 2800 look to be near adequate and at a reasonable price.
They do make a ball type version but i havent seen it for sale or know whether it would be any better.

[p2501]

Maybe putting good 120mm fans with 140-120mm fan adapters would be a good idea? You'd have more surface area combined with well tested fans.

[affiliate13]

Yes they could act as shrouds but i wont claim to know what loss or benefit might be realised.

Nano SLI... isn't that also just another kind of sleeve bearing?! How do they fare on a high-FPI rad?

25 dollars for a sleeve bearing fan?

Get an adapter they are the best choices at the moment.
They'll act like a shroud and reduce dead spots on the radiator.

That's what I was thinking, maybe I'll cut up some Yates to use them as additional shrouds on the adapters.

We really need some decent 140mm testing done, it's obvious that 140.3 beats its equivalent 120.3 (addmitedly with 140mm fan equivalents) going by skinnee's thermochill 140.3 review (http://skinneelabs.com/pa140.3.html?page=4) by anything from 40w to 100w+at the same fan speed. Even at the maximum test 1400rpm the 140.3 destroys the 120.3's with such "immature" 140mm fans (http://skinneelabs.com/triplesv2.html?page=4) with 288w dispersed at 5 degress delta compared to a gtx's 242w and the xchangers 248w and about 30w at the exreme 2 degrees delta, a 30% increase.. With fan optimisations there really is no reason to to recommend a 120 rad if a 140 can be used. This will only be magnified as fans are optimised should any 140mm users need more performance. Yate loon sh14 fans are great fans for a 140 rad but don't ignore the xigmateks in the round up i posted http://translate.google.com/translat...did%3D29848Hab

[Church]

Shouldn't 140.3 be compared to 120.4 if we take rad with similar area?

[JeffyB]

Even then they (140mm rad) have more surface area and can dissapate similar heat load with lower fan rpm, this gap will only get bigger with fan optimisations.

im using some special deltas that were a limited run. i have yet to find any more and after talking to delta engineer about them i have learned that only 100-200 were ever made like mine.

they are 24v PWM fans. i run them at 12v and use PWM to regulate speed down from that point.

i run 10 of them on 2 560gtx's and a 280gtx in my MM ascension.

you can find other versions of these fans that dont have PWM control and run them down to 8v easily. at 8v they arent any louder than a 2k ultra kaze and still move a damn good bit of air.

san ace has similar fans that move a ton of air and can also be undervolted quite a bit.

i have had push/pull yates and koolance 140s and they dont do the job on the GTX rads but work fine on the SR1 series. evercool also makes decent CFM 140mm fans and they would likely work in push/pull for sufficient cooling.

[Genesis:.]

i wish more companies would come out with 140mm fan options for rads...

[Fitseries3]

just found these in another thread here on xs...

Those tests compare Rads ONLY. Not having different fans on them.

re: Yates
I have about 30 yates running 24/7 , 12 have been horizontal, none have died. (from jab-tech).

[gmat]

Noiseblocker, Thermalright make nice 140mm fans. I have 2 TR fans on my 280mm SR-1 and they push a nice airflow, and are surprisingly silent (even compared to Scythe GT's that are not far from them).
