Watercool MO-RA 3, anyone know something about it?

[skinnee]

Lol, I'm not sure, but I believe we've been waiting on such a test for more than a year or two. Possibly (and probably) since the release of 9x120 radiators.

Your wait will be coming to end, just gotta get through my current rads to test first...

[Church]

skinnee: universal gpu blocks first

[skinnee]

different bench (building a fourth bench for dedicated pump testing), but yes.

[bundymania]

@alexandros: The Version for 140mm Fans is available since Middle of November - i was waiting to include it in this test too.

@churchy: my goal and the wish of most users who were asking was, only to have monster rads in this review for comparison. i already have other tests with all sorts of "normal" rads released in several forums. this review is to show, how a high end sys with 2xgtx480 and oc i7 runs with those big radiators first i was thinking to include a quad radiator, just for little extra comparison, but the watertemp was over 50° celsius in summer...at it´s limit, so not what a watercooling sys. is "made for"

[Church]

bundymania: it's just that i heard many times - MoRa - round tubes - bad, 2*3x120 RX - same cooling but less resistive and more compact, and hoped to have that proved or disaproved with same test. I've never seen test among such combinations, at most - MoRa vs big single rads like 4x140/3x140/4x120, which is much further from apples to apples comparison, as rad areas differ too much, and MoRa has more then doubled rad area/fan count advantage. As this test has passed, we can only wait for another (probably by skinnee?).
On MoRa cons - more flow resistance (partially fixed with MoRa3), on pros - sleeker/better looking packaging vs separate rads of same section count interconnected, +if it's performance is close to three triple rads, then MoRa wins by pricing too. If MoRa cools just up to two triple rad level, then later imho is preferred choice, as cheaper (especially if you include lesser fan count/price), more compact and flexible mounting options and possibility to separate in loops.

Offtopic: Skinnee: out of curiosity, what do you use for yourself as your pc/rig? Or you use some gathered parts/leftovers from tests on some testbench case or even have that assembled on table?
And you could sometimes make some article with walktrough pics from lab/room, different testbeds, parts storage gathered by time and so on

[skuldarin]

I'm about to order a couple of 9x120's of these and see how it works out.

currently i'm running a 4x120 BlackIce GTX X480 with a single MCP655 pump. it's fine for the most part for temps... infact temps are just perfect for a 980X OC'd to 4.3ghz daily and a HD5970 OC'd to 950 core and 1253 mem. it's also running through a koolance full board block on an ASUS RE3.

the biggest thing i was shooting for was a quiter running OC'd system. if the MO-RA3 gives the same temps with quiet fan operation, that's all i need .

granted, i will be keeping my 4x120... it'll come in handy if i end up going... a tad bit extreme.

EDIT: oh, system water idle temp is roughly 43-44*c during winter temps. summer is around 48-49*c, full load never goes higher than 52*c in any season.

Sorry church, didn't see your post until now.

No, not some cobbled together mess... well, compared to some of the builds we see regularly I guess it is. My main rig has to be separate from all the lab stuff or it would never be running. Daily driver spec's...

Mountain Mods Ascension: Annodized/Brushed Alu
Asus Rampage II Extreme
i7 920 D0 @ 4.2 with 1.275V Vcore
Corsair 3x2GB DDR3-1600 (Kit just won't clock, so it was worthless in the lab... also why I won't buy Corsair kits anymore)
EVGA GTX280 with Danger Den block (EK blocks were moved to one of the test benches)
Corsair HX850
Sunbeam Rheobus Extreme
3 Thermochill PA120.3's Yate Loon Mediums
3 D5's w/ stock tops
3 EK Multi-res 150's
Heatkiller LT
Koolance VL4's, Colder QDC's
Primochill LRT tube; blue, white and clear

No board blocks presently (previous system did), so that loop just cycles from res to pump to rad all day.

The Lab and my office area... they're never tidy enough for photos, parts and tools strung about. It gets out of control quickly with 2 test benches, a radiator test fixture, separate pump test fixture and prep table. Its controlled chaos really.

I think 4X180 will give you a lot less noise than 9X120"s

coolhandluke41: depends on fans. And 180mm fan selection is even more scarce then 140/120. Even less chance for some of those very few to be exceptionally good. Remember Martin tests, where best 140mm fan was .. 120mm gentle typhoon with 120>140 adapter? .

I agree 180MM selection is very poor...but most 7~9 blade fans @600~800rpm will do ,SilverStone FM181 is probably best bet or;

[skuldarin]

at the moment i've been using 7 blade Rosewill RFX-120's. as long as they don't go higher than about 1200rpm, they're just about dead silent unless you put your ear to them and they still push a decent amount of air. eventually i wanted to replace all my rosewills with aerocool's shark 15 blade fans. 26db at a little over 80cfm is pretty darn good if you ask me.

EDIT: or those noisebreakers, the NB-M's. mmm sexy

[Church]

coolhandluke41: i also suspect for very little air pressure for those big fans with that much open space between blades = even more airflow loss on rads. so imho smaller fans -> better performance.

I beg to differ!...http://www.xtremesystems.org/forums/...3&postcount=70

It's all in what you think is best, performance being best to me, the San Ace stomps the GT AP-15, and I now have a box full of various Nidec GT's because of Martin's testing.
I love 'em my favorite might be the new AP-29. This shows where I'm coming from in my judgment on the best fan.

The best part is Scythe is now offering many,many different speed GT fans

[Church]

the finisher: Will San Ace stomp GT even performance/noise wise? And especially at acceptable noise level diapason? NOT just maximum air flow wise that fan can push or what it can push with noise no one wishes to tolerate it running at? Somehow i have my doubts in high-speed downvolted fans being quieter and pushing more air with their characteristic ticking at low speeds, their blade design should take a toll on pushed air flow at 900-1100 rpm range too.

Sure you can strap on a bunch of high CFM/RPM fans and shrouds for a bit better performance but you will missed the whole point about this RAD ,it's designed for very quite/slow moving fans...I would't use more than 1200rpm fans on them,so if you want to improve your delta add more of the same..more slow moving fans,otherwise the round tube dilemma will become a factor

Fist of all "acceptable noise level" is a very subjective thing.

In the application I've dreamed up for them, I believe the answer is Yes. And this will stand up to MORA 3 as one of the best Monster rad setups.
First of all, the fans run from 5v to 24v, they start scaling well @ 10v, and are the most quiet of all 140 fans tested to 12 volts,[in Martin's test] db to cfm ratio is top notch at low speeds. And they move almost twice the cfm @24v.

Because of this performance, I can sandwich 3 between 2 PA140.3's. Because of the PA's efficiency, I am using only 3-140mm fans to MORA 3's 9 fans. Because of the awesome shrouds available for the PA140.3, my fans are 33mm from the rad surface's, and there is no air leakage at all.
Since the fans are enclosed between the rad's they should be much quieter than 9 140 or 120 fans out in the open. And I have voltage control from 12 to 24 volts, this setup should be very quiet @12 volts, and have awesome performance @24 volts.

Given the availability of the fans, and now the PA rad's and shroud's, this probably isn't an option for most people.
Since neither MORA or my setup [9.5" wide when done.] will fit any commercially available case internally, this is a fair, but maybe pointless comparison.

But we are talking "Best" here

I'll put it up against anything out there. If Skinny tests MORA 3, I'll drop this setup by his house to test as soon as it's done, I live nearby in Minnesota.[again, probably pointless]

This is what I have so far, fans are totally rubber mounted for minimal vibration transfer to the shrouds. PA120.3 in the background.

[DexNfX]

Those silver fans really look sharp.

I just ordered a MO-RA3 9x140mm

[ElGreco]

I just ordered a MO-RA3 9x140mm

May I ask you, whats the reason you preferred the 9x140mm edition from the 9x120mm or 4x180mm?

Also what fans are you going to use and at what RPM?

I am about to order it as well, but due to lack of extensive reviews I am not sure which model I should prefer... I dont even know how much heat can this beauty dissipate (in watt) or whats the pressure drop or how many pumps would be sufficient...

Any info on that would be MORE than welcome!

[miahallen]

I'm going to use 9 120mm Adda 98CFM fans with 120mm to 140mm adapters. I decided on the larger one since there was minimal price increase and a much larger surface area...plus I was planning to use ducts/adapters anyway.

Thats nice! Still, I suppose that you will not be able to use the stock cover of MORA3, if you use the 120 to 140 mm adapters... or you dont care about it?

Also, if you dont mind, what kind of ducts/adapters are you thinking of using?


Thanks!!!

Actually, I've changed my mind on the fans I will use....I'm gonna use 9x 120x38mm 117CFM San-Ace fans. The adaptor will be custom made from a sheet of wood with 120mm holes cut for each fan, and routed to larger openings on the radiator side.

[miahallen]

Anyone who where I can get a template for cutting fan holes for the 9x140mm version?
I found the manual and the MO-RA 2 dimension diagram here...but cannot seem to find the fan cutting templates for the MO-RA 3 rads

[Church]

miahallen: try to find somewhere what fan spacing 140mm mora3 has and use multiple mnpctech's 140mm templates. But even then .. i'd better wait for the real thing to arrive on hands then risk to botch expensive case when cutting it with "supposedly" right template dimensions.

[miahallen]

Well, I got the rad and all is well. Just finished building my new benching loop and finished a blog on it here:
