News New massive liquid cooling radiator weighs over 35lbs, holds nine 200mm fans — MO-RA IV 600 costs close to $600

[Admin]

Watercool introduces the MO-RA IV 200, 400, and 600 radiators, which can accommodate two, four, and nine 200mm fans for the ultimate cooling capacity.

How loud is it? Article is not clear if it comes with fans, or they would have to be sourced/installed separately. I would assume if it comes with fans, they should provide some kind of datasheet showing performance, such as ex. (9) fans spinning at 1000RPM with produce 35dba and provide 1000W of heat dissipation. Without any of this information, this article is nothing more than a cleverly disgusted advertisement for a product we know virtually nothing about.

What that much radiator and 200mm fans, they should be nearly inaudible at low speeds. The smallest one should be the loudest all things considered, but a lot would depend on the heat load.

Pump noise is likely to be louder.

New from them, but AlphaCool has had a 9 x 120mm radiator for a while now. And a lot cheaper (when it was available. That's just looking at my wish list from Amazon Canada).

 

[Eximo]

9x200mm is just shy of three times the area of 9x120mm though. Even the smaller 4x200mm is a little bigger than 9x120mm.

That middle one is almost practical. The big one, kind of a statement piece.

Ever since I saw Alphacool's first version of these I thought that if I lived in a place that got hot with no AC it'd be tempting to build a frame and stick one of these in a window.

They're still available and sub $200 USD: https://shop.alphacool.com/en/shop/...nexxxos-xt45-full-copper-1080mm-nova-radiator

yea, I knew they would be. I was just pointing out that AlphaCool has had that for a while now, so they aren't really new.

I'm using 3x420 rads, with 9 140mm Noctua fans spinning at around 450rpm. I don't hear a lot of noise.

Intel has a new CPU ready that will need this.

 

[vinay2070]

Good for gaming laptops that can take water loop connectors. The CPU can work at good boost frequencies then.

It's a radiator, a solid state object, so it's, well, silent.

You will want to add fans to it, obviously, and you'll want a strong pump to push all that liquid, given that the big one holds over 3/4 of a gallon of coolant just inside of it.

So, like always, it depends on the rest of your hardware. The way physics works, though, 200mm fans can move more air at lower RPMs than smaller fans covering the same area. Most of the ones I've had are nearly inaudible, but then again, I've never had ones designed for the level of static pressure required to push air through a 3" thick radiator. I've only ever had them as large exhaust fans.

Still, I would bet money on this being quieter than a 360/420 radiator setup, let alone one of those 9x120mm beasties, assuming it is correctly set up. And none of those are particularly loud to begin with (again, when properly configured).

It won't ever match a passive heatsink, of course, even with no fans, since you still have a pump circulating coolant, so if you want a truly dead-silent setup, you're still stuck with one of those, and all the thermal limitations they come with.

Finally something that can tame a 4080 and the 14900k at "stock" ?

If you are at the point where you need that big of a radiator, just connect the water block to running water from the local utility.

 

[purposelycryptic]

yea, I knew they would be. I was just pointing out that AlphaCool has had that for a while now, so they aren't really new.

Except that comparing an AlphaCool 1080 to this would be roughly like comparing a 120 radiator to a 360 radiator.

AlphaCool 1080 surface area: 360mm x 360mm = 12,960mm²

This monster: 600mm x 600mm = 36,000mm²

And the thickest, bad-assest AlphaCool 1080, the Alphacool NexXxoS UT60 Full Copper 1080mm Nova, is only 60mm thick, vs 75mm on this thing, for 25% additional girth. I would be interested in comparing the fin density between the two though.

There is a reason the AlphaCool weighs 3.7KG, and this thing 15.9KG. Fill this monstrosity up to capacity with coolant, add a grip to it, and you could use it for weightlifting.

I'm not saying the AlphaCool isn't ridiculous and badass, it just isn't punching in the same weight class as this monster. Literally.

 

[purposelycryptic]

They better offer a full set of rack-mounting options for this thing...

 

[HyperMatrix]

Curious about the performance difference between the MORA IV 400 and MO-RA 3 420. The new model is slightly larger in every dimension but with smaller coolant capacity, and price is a lot lower. Likely more focus on fins. But still find the price drop to be curious. Look forward to benchmarks.

If only tap water were cheaper than electricity in 2024...

It would be cheaper to take out a loan and install a heatpump than run the water 12hrs/day

 

[neojack]

ah the glorious days of custom watercooling !

2 pumps in series are better than one big pump. less noise and some redondancy.
source : i tried both on an external rad setup.

also, use quick disconnects fittings between the PC and the eternal Rad
source : i tried both....

but TBH the best setup is one big case with lots of rads inside.

Ah the early days of water cooling when I could be happy with 2 pumps. Now I’m running a 6-6-66 setup. 6 rads, 6 pumps, 66 fans. Unless something breaks down I’m good on cooling performance for the next decade or two. Lol.

Regarding one big case…unfortunately it’s very limited in usefulness. I first started with 3 pumps and 4 rads in a Corsair 1000D. 2x Nemesis GTX 360 and 2x Nemesis GTX 480 With push/pull config and 3000 RPM fans. Just not enough airflow.

Adding 2x Mo-Ra3 to the mix was a blessing. I made quick-connect inlet port on the back of the case, as well as I believe a 5v molex power to trigger a solid state relay that gave power to the pumps/fans on the Mo-area automatically whenever the PC came on. Huge improvement in cooling performance.

In the future I’d probably do a fully clean build with no radiators at all in the case and just hook it up to the 2x mo-ra3. Or a single one of this new massive Mo-Ra4. Better cooling, less noise, and most importantly….much easier to take apart for cleaning and maintenance. And you don’t need to use a massive case. Can use whatever you think looks good.

 

[junglist724]

I'm still not a fan of them using tubular copper channels. MO-RAs are always so restrictive to flow.

 

[edzieba]

We've wrapped right back around to the "I hooked a car radiator up to my CPU" era of watercooling. What next, is DangerDen going to suddenly revive?

 

[Neilbob]

Makes me think of the old Zalman Reserator I used to have, when I had my Athlon 64 I believe. That thing had some heft and was on the edge of being totally impractical, but how I loved that crazy chunk of metal. There was no OC headroom to be had, but except for slight pump noise that could barely be discerned, it was SILENT.

But even the weight of the Reserator didn't come close to this monstrous MO-RA 600 thingy.

 

[OLDKnerd]

Dandy. But i would prefer a RTI Arms Mora air rifle

already have 4 all copper rads lying around for next build

I hope you realize it was a sarcastic remark.

 

[sukebe]

Go to the junkyard, get a small car or motorcycle radiator with its electric fan and temp switch. Spray out the bugs, weld in or 3d print an adapter.
You just saved $530 bucks.
