So, obviously the surface area of a PA 140.3 is best, but what about total performance when taking into what fans are used? I'm a firm believer the fans are as crucial as the radiator and a mismatch is as bad as crappy fans and/or radiator.
It seems the front runners are only two options:
- Scythe Gentle Typhoon 1450rpm, 85 m³/h (50 cfm), 21 dBA, 40mm height w/ Bitspower shroud.
- Yate Loon D14SM-12 1400rpm, 105 m³/h (62 cfm), 29 dBA, with noise comparable to GT 1850.
Conditions:
- 1400ish rpm fans best choice of quietness/performance for Thermochill radiators
- GTs (and 120mm fan category in general) are more fully-optimized fans with best noise and tone quality
- 140mm fans more fully utilize radiator size (example: Feser Monsta tests with 120mm fans vs 140mm fans) and in smaller height (25mm)
- GTs use double ball bearings, Yate Loons use ??? bearings
This seems as a complete spec comparison we can get untill someone tests this stuff. On a side note: if total height is a concern, what would using a plate gasketed to the PA 140.3 with 3 120mm holes cut out on fan center do in a (1) pull config and a (2) push config versus using the 15mm Bitspower shroud. I'd imagine, if fans completely sealed to the radiator, it wouldn't be much worse than using the shrouds, especially if pulling when the rad is mounted flush to a case's exterior wall - it's all sealed like with the shroud and the radiator has a bit of space between the fins and fan mount anyway.
The Yate Loons that most people use are Sleeve Bearing. Ball Bearing YL's are available, but not common and I believe are louder than the Sleeve Bearing ones.
Assuming I linked to the correct Yate Loon's product spec sheet above and here, they have the exact specs (29 dBA included, but maybe the tone's different) for their D14BM-12 and D14SM-12 models. The D14BM models are footnoted with "ball type," which I assume means ball bearing. Thus D14SM should equal the sleeve bearing. The only thing I don't know you can't make equal is the static pressure; it isn't listed on Yate Loon's product spec sheet and because sleeve bearings are said to not perform as well as ball bearings - is that because of static pressure or lifespan or what?
As for actually finding them, all the usual places for cooling/computer components (sidewinders, petras, ppcs, frozencpu, newegg) only carry D14SM models.
I believe its the tone, although I haven't compared them myself. I know the YL spec's are considered pretty accurate. Ball bearing fans are said to last longer, and they have no issues with mounting in any orientation. Sleeve Bearing fans typically work best mounted vertically.
I am not in the US, so have no idea where to source them there.
One other thing. Just because its a Yate Loon fan, don't assume the quality is equal across the lines. They also make 38mm fans, but they are not on a par with the 25mm fans (at least according to Petra's). That said, I have a bunch of the 140mm SM fans, which I think are pretty good and equivalent to the 120mm YLs.
EDIT: I can't find the thread I read comparing the ball vs sleeve yatesI think it was at SPCR but can't find it now.

Adapter plate to allow 120mm fans to be used on the PA140.3 or vice versa.
Not the best solution as no doubt someone will point out, but it's much cheaper than using 3x of those 140-120 shrowds and it can also be used the opposite way round to mount 140mm fans onto a 360mm rad.
Few amendements to be made before I run a batch off but it pretty much works as is, final finish will be satin black.

I wonder if that nets you much performance gain over using a 120.3?
you should spread the fans out marcus, that way they can at least attempt to cover the most area possible. just make sure to cover the space between the fans so no gasket is required(I think its a great idea though, what youve done with the adapter plate)
Why just not use the 140mm fans? No point putting 120 on 140 rad, when you have couple of really good 140 fans, plus few new brands coming soon.
Also, spread those fans a bit, try to put them exactly in the middle of 140mm spaces. Air would through the center of the rad and spread a bit on other, not covered parts.
Other thing is - I found that Scythe has 140mm fan, but its not for retail sale - the one thats mounted on one of their CPU cooler - ZIPANG

I agree with the increased performance on a 140mm fan size wise, but there isn't any 140mm fans that perform as well as their a respective 120mm, all else being considered equal. That Scythe fan you linked seems to be sleeve bearing, which the leading 140mm Yate Loons also use. Hopefully the rumored 140mm fans Scythe is coming out with are larger GTs or at least something reasonably quiet with good bearings.

Sorry to revive this, but hoping someone can answer.
Does anyone know what the fan hole spacing on the PA140.3 is? I thought I remembered seeing the number 25mm thrown out at one point, but can't seem to find it now. Pages listing it for sale also don't specify. Can any of you guys that own one confirm?
I know the HWLabs GTX420 shows 20mm spacing on their schematic, but I'm hoping it is closer to 25 on the TC 140. Thanks.

Cool. Can you also tell what is the distance between rear of the rad to last fan hole just before barb?
