Thanks for this detailed review! Price is a bit steep though..

Very nice coolers with some interesting details but those prices... Asus must think they are the Apple of PC parts... Great reviews as always!

Great review! Finally the 8700K is delided and temperatures are more objective then ever.

Geez those prize tags... Solid review as always. Surely the Noctuas Industrial fans increases the price. Atleast that is covered well. Can´t wait to get my Industrial fans, just getting bigger and badder, 3000rpm 140mm ones. 120mm would suited alot better for me, but meh, prize was same.

buhehe:

Wow, a whole year and a half?

Lol yeah that was funny. I have a hybrid copper aluminum H90 for what 5years now and still no issues.. It cools just as it cooled day1 60months ago, nvm corrosion paranoia. If you use non conductive thermal paste all will be ok. 😉

Thank you for the review. But I did have a question about it. Maybe I missed this in the review itself, but, how did you monitor the temps during the BASE and OC tests? I only ask because this cooler gets its info from the asus AI suite... which tends to be 5-10c off from actual temps. Normally it reports the temps too low. Just wanted to confirm it. Thank you for your hard work!

I read another review about this cooler and what they said was that the CPU temp for the AI Suite is taken from a temp probe on the mother board, (this was apparently checked with ASUS) this is why there is a large temp difference, so the unit does not report the correct CPU Temp, therefore the fans on the unit did not react / speed up in time to react to real world temps, they also said the secondary fan for the cooler was a good idea, but as a small fan it can be noisy, this is what was reported here, https://www.overclock3d.net/reviews/cases_cooling/asus_rog_ryuo_240_and_ryujin_360_aio_liquid_cooler_review/1 see section 4 a good cooler that needs a few changes to make it great

These are looking good. Pricing is a bit steep but the build quality is appears to be there and they have they have legitimately good fans!?

Its clearly not worth to pay for this as noctua on air does job similar and cheaper. And safer...

I still don't get why manufacturers mix metals with these AIO's Copper Cpu Block Aluminum Radiator? I am sure somewhere down the road they will have problems due to the mix of metals. I personally have a Alphacool AIO Copper Cpu block Copper Radiator and its been in my system for nigh on 18 months now no issues at all. Just Seen the price my goodness that is expensive 130 uk £ for a 280 Alphacool AIO here, NO fancy lights though.

Copper is good at absorbing heat but but less effective at letting it go. thats why copper cores and aluminium are are used in cooling solutions whether air or water based.

Thanks, I'm glad that you like it.

I had Alphacool AIO in the past and to be honest - it wasn't any better (performance-wise) than the alumin

It's not cheap, for sure, but you won't get OLED display elsewhere.

Yes, it's always better to test the CPU with solder/delidded as the TIM would definitely flatten the charts.

Noctua fans are the class of their own, almost always (I didn't like the Redux in the past).

Not really, copper is still better at dissipating the heat 😉 . The main reason of using aluminum is the price, not the potential 😉

I had no issues with reaction of the fan curve, but still Ai Suite is not a good utility for measuring the temperature.

I use HWMonitor or HWInfo. I knew already from the past (like in Maximus IX Code) that Ai Suite is not good at indicating the correct temperatures 😉

outstanding job on the review. for Asus, too much for too much. if they really wanted to grab attention and fan $$$, come out with a branded aio monobock matching the mobos. otherwise, noctua or NZXT, alphacool, etc...

I have had my Ryujin 360 for a month now it's not bad and is very quiet once you use fan xpert and run fan the main fans at 400rpms which is mounted to the front, I guess the R7 1700 must take the temp from the motherboard probe as the temps match with whats on the display. Typically idles at 35C maxes out about 52C typical gaming loads around 43-45C on ultra quiet, this is with the 1700 at 4GHz on all cores and 1.438v. This matches what CPU Temp says also, i might give HWinfo a go but last time i used that i find it a little clunky. It's quieter than the Noctua nh-d15 and cooler too on low but then again inorder to mount the Rog 360 i had to get rid of the 2x 140mm front fans, 1x 140mm fan on the top and then the 2x 140mm on the Noctua so lost alot of fan which helps noise alot even if they were all running on low 500rpms. As for mixed metals Jaz2centz recently cut open a corsair H100 that he got 5 years ago and found there was zero corrosion so it appears the corrosion inhibitor in the fluid is working pretty well. He was disappointed because he has now ruined a perfectly good cooler lol. Can't get Fan xpert to work properly however as the system will thermal shut down before completing as it appears it turns the pump off and takes a long to complete. Even decided to run the 1700 at stock at it was hitting 100C and thermal throttling during the fan test. Software is still garbage sent a ticket to ASUS to sort that crap out. The pump should not be turned off while doing the tests or it should be done before any other fans are tested to prevent water from boiling away.

@GREGIX show me a quality aircooler, that has a 5y warranty covering all components that get damaged if it fails, since corsair offers it on their AIOs. im using WC since 2005 when i started with a custom loop, not one failed, not one leaked during the time i had it, or anyone that bought it from me. yet ive replaced many broken air coolers (mainly stock ones) so yeah, i still stick with water. i know asus has quality stuff, but using an asetek pump (design) is not what i want at that price.

sure good warranty, but only for the product itself, not for cpu/mb/ram etc, which corsair covers, in case their aio fails.

TurboPenguin:

I hear the fan on this for cooling the VRM's is super loud... sorta defeats the purpose imo

At max speed yes, just like Cryorig A40/A80 series. [SPOILER][youtube=KsmKEYmlEZk][/SPOILER] https://www.legitreviews.com/cryorig-a80-hybrid-liquid-cpu-cooler-review_179437/5

REALLY!! now go to the corner and think about what you just said! It's like you won't buy a rock unless it has a 5 year warranty. Thats because besides the fan there is no moving parts thus the HS can NEVER fail. Alot of people have spare fans if one should fail just replace it, if an AIO leaks (my swiftech H220 did at the joint of the block) you are fked, if the pump fails you are fked without lube because the system will thermal shut down before you get into windows. Sure you can go through the pain of contacting support getting an RMA providing proof then sending the part back then waiting on a replacement.... This is down time and for some people this can be a huge thing, in my case it took swiftech to send a replacement 3 months!! Needless to say i gone out and bought an apogee block and EK res and pump combo which was total garbage. That failed 3 times, once pump died and the other two leaks started to happen in the cheap ass acrylic, seems them res and pump combos have major issues when i looked around if i recall it was the vibrations from the pump would fracture the acrylic and it happened about every 9 months. Also the water block was nickle copper and the rad was also copper and maybe the connectors were aluminium so may have mixed metals in the waterloop when i had to expand the loop from switchtech plastic connectors to accommodate the res and pump. It was my first watercooling setup and mixing aluminium with copper never really occurred to me and i doubt the algae inhibitor would have done anything for it.

Yeah first thing i did with mine is turn it down to 10% lol lucky the Crosshair VI VRM is pretty beefy so doesn't get hotter than 45C anyway, although with the DH15 it was 35C. Still well within acceptable thermal tolerances. Although if turned off they can reach 52C so they do indeed help put you don't need it running at max speed just something that provide a little air flow to move heat about so it can be captured by the exhaust fan.

What if you use it at idk 30-50% speeds is it still "loud" or what would be the threshold between loudness and cooling efficiency. Does it cool at all at your 10%?
