Review of postings for Asus ROG Ryuo 240 AIO Water Cooling Review (the latest posts first)

At least I'd be very surprised, but nothing is impossible
Our tested Asus ROG Ryuo 240 AIO has a 4pin connector.
As long as the cooling performance doesn't suffer as much, I wouldn't worry lowering the pump rpm.
But of course this is not a recommendation, it's just us; you could ask the manufacturer of your AIO what they recommend 24/7 for their pump.

Thanks for your answer. The pump in in the test has a 3 pin plug and no PWM. I do not think that the Hardwareluxx guys are THAT incompetent :-). However, when you say
I think it's no problem to lower the pump speed within its range.

what IS the range of an ASETEK pump?

Welcome to our forum Rolly.
7 Volt Adapter for PWM power connection is no good idea.
And when the pump is working after emitting smoke, it may be they just fried the sense pin with a wrong pinout.
When you don't keep care about the pinout, it's possible to plug the 3pin at the 4pin connector a pin next to it and destroy the sense.
I think it's no problem to lower the pump speed within its range.

Found the article in question:
https://www.hardwareluxx.de/index.php/artikel/hardware/kuehlung/49246-enermax-liqtech-ii-360-black-im-test.html?start=5
Wir müssen auch davon abraten, die Spannung für die Pumpe zu reduzieren. Als wir einen 7-Volt-Spannungsadapter nutzen wollten, stieg Rauch aus dem Pumpengehäuse auf und zwang uns zur Notabschaltung. Immerhin hat die Pumpe diesen Versuch unbeschadet überstanden.


Translation for non-german speakers:
"We also have to advise on not to reduce the voltage for the pump. When we tried a 7V voltage adapter, smoke was emitted from the pump casing and forced us to an emergency power down. However, the pump survived this without taking damage."

I agree that reducing pump rotation via PWM might be better than using lower voltage, but still...

Hi Henro,

AFAIK I read about that on one of the usual German suspects (tomshw.de, computerbase.de, hardwareluxx.de). The problem seems to be that the pump itself, esp. the bearing (not the electronics!), requires a constant throughput to keep temperatures down. I distinctly remember an AIO test where one of the testers wrote of a pump literally emitting smoke before he turned the system off and reajusted pump speed. Unfortunately, I am not able to produce any evidence for that. But given that nearly all vendors, including ASUS, use some ASETEK build, I thought it would be safer to keep pump speed at max. Fortunately, with my build with a BeQuiet DarkBase 900rev2 (I just love that company :-)) and Noctua Fans on the radiator I do not hear anything from the pump outside the case...

regards, Christian

Hey Christian ,

I have setup several solutions with lower AIO pump speed now and none of them has overheated , so from my point if view it is safe.

Could you explain which part you mean? The electronic?

Hi,

thanks for your intensive test of the Asus Ryuo. I recently bought this thing, replacing a BeQuiet DarkRock4 mainly for optical reasons. I replaced the standard fans with Noctua A12x25, keeping the noise level really low. Fortunately, I have an Asus motherboard (Maximus XI code), so I in fact can use AI Suite3 to controll the fans and Aura Sync to control lighting effects (Aura does not detect my motherboard, so effects are still quite limited).
All in all, installation was pretty straight forward, cooling is quite good and the noise level equals my beloved DarkRock. However, I have a question that still bugs me: You said that you used PWM to control pump speed. When learning about AIO coolers, the sources mostly said to run the pump at full speed because of the very real possibility of the pump itself overheating when it has not enough throughput. Right now, I have the pump speed set to full, ignoring any optimization. Can you comment on that?

thanks in advance, Christian

The selection of AIO water cooling is huge. Therefore, in order to stand out from the crowd, new ideas and unique characteristics have to be produced. Today we are testing the Asus ROG Ryuo 240 AIO watercooling with addressable RGB illumination and OLED display, which wants to achieve exactly this: To be like no other AIO! As always including new videos and 360° view :tv:

Many thanks for the support to Henro & the manufacturer Asus and enjoy reading the new review :coffee:
