Watercool Announces the MO-RA IV Radiators for 200mm Fans

The MO-RA IV series is the perfect choice for anyone seeking maximum cooling performance and excellent build quality. These monster radiators are fully modular and versatilely expandable, ideal for overclocked gaming computers, workstations or servers that are in use around the clock. WATERCOOL has optimized the fin geometry to increase performance across the entire speed range. The German manufacturer has now opted for so-called corrugated fins, which are designed to provide more power.

In addition, the pre-chamber has been optimized. WATERCOOL has raised the pre-chamber to ensure better pressure distribution. The solid brass connection terminal is now soldered to the tube geometry. This ensures greater mechanical stability and a maximum pressure of up to 5 bar. All MO-RA IV units are thoroughly pressure tested before despatch.
Modular and expandable
The MO-RA IV series can be upgraded and customized extensively. Whether wall mounting with the WALL MOUNT or the installation of a flow-optimized MO-RA TANK with one or more D5 pumps - the possibilities are almost unlimited. According to the manufacturer, you can assemble an external cooling station in a class of its own, naturally with the highest quality workmanship.


User-friendly and convenient
Thanks to years of experience and a lot customer feedback, WATERCOOL has integrated numerous convenient functions. The newly designed fan frame can be installed without screws via Quick Mount, and the fan grill also snaps tightly into place, thanks to a special ball mechanism.
Perfect control with passive, active and aRGB
With the optional passive control, the fans and pumps for the MO-RA IV can be controlled via the mainboard.
The Active Control, which is supported by a microcontroller, offers additional options. The outstanding features include an alarm function, integration of the WATERCOOL FLOW, monitoring of the fill level and display of digital temperature sensors. The Active Control can be conveniently controlled via software or the optional display, which ensures flexible and user-friendly management.

Perfect cable management
The integrated fan frame includes a fan splitter so that all fan cables can be installed out of sight. A 4-pin male to male cable is fed through the back of the MO-RA IV and connected to the computer.

The MO-RA IV series is now available for pre-order at shop.watercool.de. The manufacturer estimates a delivery time of around 30 days.

Seems nothing special. It is an ordinary heat exchanger in a fancy box.
What I want to see in a package is a water cooling radiator in an weather proof box and a kit that could goes trough an average windows sealing, so I can push the heat outside, instead of heating my room.

A Computer GuyThis looks fantastic. I've been wanting to downsize my main rig case and a few quick disconnects to MA-RA would make it happen.
Thats really what im eyeing for my next rig. But idk if ill really be downsizing, or just switching cases to the Geometric Future Dharma and then running the MO-RA IV 200 outside the case.

PunkenjoyWhat you are experiencing is the dew point reaching the ambient temperature.

This is a view for my weather station for the last 24 hours. You can see around 6 AM, the dew point and the outdoor temperature get real close.



If we look at humidity level, we can see that around 6 AM, it was near 100%.


Hotter air can hold more water than colder water. A 50% humidity at 5° C have much less water in suspension than air at 30° C with still 50% humidity. Actually the % of humidity is the % of the maximum amount of water you can hold in the air.

I live in a colder climate and we experience the opposite in winter. The cold air from outside get in our house, and because very dry after being heated to indoor temperature. That make the air very dry and uncomfortable. We actually have to run humidifier to keep it bearable.

So again, what you experience is the air no longer being able to hold all the water it have in it. The water have to condensate somewhere and it do not matter if the temperature is hotter/colder, the water just have to go somewhere. In that case a larger radiator would indeed provide more surface for condensation. But that is not because it's colder than air. That is just impossible without something that would actively cool the water.

Also, all this assume you have no air conditioning and you open your windows to cool your house at night. If you have an air conditioner, the temperature will be stable and it will remove humidity from the air anyway.
This is from a certain place in the tropics where I happened to live years ago:

That graph is from July 2024 and you probably won't believe but they're currently experiencing a drought. That place has high humidity all year and very high temperatures meaning a lot of water in the air. When the temperature drops at night all the excess water has to go somewhere.

And no, air conditioning is not very common there. Maybe 1 out of a 100 homes have one or more rooms with air conditioning and thats about it.
It's not like you'd need a radiator that big if you have air conditioning unless you're doing something out of the ordinary.

I do wonder how it stacks up to something like Alphacool NexXxoS XT45 Full Copper 1260mm SuperNova Radiator since the designs are so radically different

Not gona lie. For a moment the wording on the picture seemed like MOPAR. But that would require just a single big fan. Sorry for the sh*tposting, though.
Broken ProcessorHad an setup a while back using Mo-ra 420 with an zalman reserator V2 and it was silent the fans only kicked in once in a while even under full load but when they did kick in they where on for a while because they had 6 liters of coolant to cool but man I loved that combo.
420 is not exactly 6 liters, but rather 6.88, and is V8. But 440 is still a superior stuff. :laugh:
I hope you will get the dumb joke:p.

They are really close but the mora 3 is better, for mora4 we need test but it should be improved even more.

Are there even any decent 200mm fans available? Or can it also use 120s or 140s with an included adapter shroud/plate? Or would it be cheaper to just by a 12v automotive fan almost the same size as the radiator unit and just mount it to the front with some shrouding?

ChaitanyaThis should be a good solution to dump heat from PC outside the room/house(granted pump used is sufficiently powerful).
this, would be tempting adding one like this outside through a hole in the wall, then complete silence inside

Looks like a new age wind farm that should be floating off the coast.

Just when i put my MO-RA3 420 together and purchased another for a future build....bit of FOMO going about, but the MO-RA3 is tried and true over a good number of years.
Plus no fancy gimmicks like that light up thing, power ports, etc...

Yep, I will keep telling myself that until I believe it and remove the MO-RA IV pre-order out of my cart..
