New EK 140mm Rads... Just received the photos in my email.

[Eddy_EK]

OK, I checked;
EK. Phobya and Magicool have same ~15mm spacing, also LianLi...
Coolermaster Centurion 590 has 20mm...

[gmat]

My Lian Li case (A71F) has 20mm spacing for 140mm fans in front, since the 2x140mm SR-1 fits perfectly (or does the SR-1 use another spacing ?). I also believe the other Lian Li parts like 2x140mm tops have the same spacing.
And what is the spacing on MountainMods 3x140mm panels ?

[Mudgey]

It seems there is a difference between European and american rad spacing.

I for one will be keeping the 140mm spacing to 15mm if I get around to finishing any cases!!

I wouldnt recommend anybody get the Centurion 590 case, its not great for watercooling and you cannot fit a 140 rad in the roof as the motherboard sits too close. The only option is to fit the rad on the top, on the outside of the case, but external rad setups aren't exactly elegant....

Eek. That means very fragmented market of 140mm rads which is smaller then 120mm already, and no existing standarts of majority others can follow. Well, at least if EK is not alone, maybe there will be more possible radgrills for their rads aswell.
Eddy: btw, it's not possible to make rad 'universal'? Afterall, it means redrilling just one of two fan mountpoints for dual and two for tripple (leaving middle fan screwholes as is, but ones for 1st and 3rd rad make for 5mm longer oval shaped (or another drilled hole set 5mm furthier) , so that user can mount in both ways/both spacing types ..)

[Eddy_EK]

I thought of adding some mounting threads but tuat might ruin all the looks.
Will have to check...

I think the problem is that right now that is no standard for 140 rads spacing.

So case manufacturers do what they want.
For example: xigmatek has 21,65 mm fan spacing :S

[Church]

Eddy_EK: whatever choice you do but imho something should be done. It's less of a problem with case fan spacing, as most do case mod with good old dremel for bigger rad placement then most vendors originally planned for anyway, but rad grills .. unless it's externally mounted rad, 90% chance there will be some rad grill slaped on cutout. And only ones i know for 140mm rads (for bigger then 1x140) are Bitspower's / MNPCtech's / iandh StealthGrill. All made for HWLabs 20mm spacing. Maybe because they were among first at 140mm rad market (i don't count overhyped low-volume&underperforming TFC monsta). All the rest radgrills i've seen at many LC shops are for 120mm rads. Of course, there is option for customised ones (eg. custom spaced order directly from iandh, or if moder has access to laser cutting equipment), but in big picture it will be small percentage, as most prefer buying ready made @ some moding or LC shop.
As for mentioned possible ruining of looks, imho it's a bit overrated. After all, in most cases fan mount holes are hidden by fans/radgrill anyway, and even if can be seen, eg. fanless side inside case, it's black hole on black rad, which can be hardly noticed. BTW, there is also option to make one rad side 15mm spaced, and another 20mm spaced (as rad grills are slapped only from one side anyway, so no difference how are fans spaced on rad side inside case). I'd prefer for both sides 'universal' mountholes for fan screws though, as per previous post of mine.

[Manicdan]

i would use this as an opportunity for an upsell, make a custom shroud that goes

case > fans 20mm > shroud 15mm > rad

as long as you put it all together, then attach it to the case, your fine. and you would only need about a 5mm thick shroud, which i dont think would make it horribly incompatible with cases that have the mobo too close to rads, and it still gives optimal (or better) performance due to good sealing and that extra spacing for balanced airflow spreading.

it shouldnt be your problem to fix other cases, but you can have a solution that lets people know that your offer exceptional compatibility, without sacrificing performance.

Not to mention adding extra holes 2.5mm away from the existing holes probably would just end up with one big oval hole

[BeepBeep2]

Two different versions?

Sell whatever 15mm are made as a "15mm spacing" model, start production with 20mm spacing?

I doubt it would be commercially viable really

[Church]

Hmm, how did fact that there are threads and oval hole doesn't fit for such purpose skipped my mind? But is it that bad with dual M3 holes with centers 5mm apart?

[Waterlogged]

Actually, yes. .but it's kind of an ugly hack. He could use clip nuts that are small enough and just have a small slot for the screw to pass through the rad itself, end user would decide where to put them.

[Church]

Such small clip nuts most probably will be candidates to easily get lost and yeah would look like ugly hack. Two threaded holes much better solution imho.

I think 15mm should be the standard. It became the standard for 120mm fans and there is no reason not to follow that standard.

The MCR420 uses this same 15mm standard per their drawing.

I can't see why you would want gaps between fans, 20mm just doesn't make sense to me unless there was a special fan that required the extra space.

15mm makes the most sense, cases should be designed to fit components not the other way around. You could potentially have an oblong hole in a case that would be compatible with multiple spacing standards, but you can't really do that with the radiator when you need threading.

[Mudgey]

Eddy,

For the future whilst there is still a certain amount of doubt in the air to which size may become the norm, you may want to get the next batch made 10mm longer and incorporate removeable fan mounting plates that bolt onto the side, for instance like what magicool do with their slim rads that rivet the U shaped fan holders onto the sides of their rad. You could offer a mounting plate for both sizes of spacing and even offer an extended shrouded version. The downside to this is the increased cost and extra rad mounting plates to stock.

[Church]

.. and the upside of extra drilled screwholes would be minimal increase in manufacturing costs.

But the MCR420 is a 4x120 rad? That's why Swifty's naming system really fails IMO

[Bill Owen]

I have no problem taking special orders if Eddy offers 15mm spaced version of his radiators, however special orders can mean longer wait until the mill is open after production runs.

fyi: Added a 2x140mm template (20mm spacing) Simply layer additional print outs for 280, 420, 560 Radiators

[trn]

15mm is the defacto standard in the US market for 140mm.

[Church]

trn: Please examples backing that. So far it seems on contrary, EK/Phobya/Magicool being european firms, and 20mm camp consisting of other side's of pond HWLabs and Koolance (with exception of Thermochill (UK?)).

[Martinm210]

Whoops, not sure what I was thinking there.

I do like the 140mm sizing though, if pricing comes down a bit, I may switch over myself. A 3x140 is darn near equal to 4x120 anyhow. I've just been waiting for a lower density lower cost 140mm option.

Some of these EK triple 140mm would probably work well for the base box I'm thinking about anyhow.

Is there anywhere in the US that is carrying these yet?

[Church]

Martin: just mount them vertically, so that 140mm sleeve bearing yates can be used without reduction of their life. Unfortunately there are no 140mm fans as good as GTs performance/noise wise+having ball or hydrodinamic bearing :/

[Waterlogged]

Martin, any chance I could get some short term access to you via PM?

Yeah, I might do just that. I'm just getting tired of the same old test bench with wires and dust everywhere and looking to go back internal with some sort of custom base rad box.

I guess I could also just work with case pressure and avoid the whole fan/rad direct mount.

hmmm...not sure yet.

[Martinm210]

Yeah, sorry, forgot I still had that turned off. Should work now
