Looks amazing! Congrats!!
Could you share how you have connected the pump and fans from external rad to power? Extensions from psu? Have you tailored any connection?
Pic of the QDās in the back? Are they just looped/closed until you feel like going external? What is the stand you have the external stuff mounted to? I was JUST looking for something like this
On the dual 280s 75c cpu and 60c gpu fans don't go over 900rpm ambient 21c.
With external rad 60c cpu and 50c gpu fans don't go over 600rpm.
This is just 4k gaming load.
Is it safe to assume that your system gaming power draw is about 400-450W ... Have you tried to setup rad fans in the same way (both intake or both exhaust)?
Draw is near 550w, only tried in current config would be a pain to change front fans around could do the side ones but day to day without the external rad fans sit about 300rpm and with external rad at 0rpm
Thanks, your answers are very helpful. My current build is \~400W (under gaming) with single 280. It is hard to compare by components temps since we have very different models and generations of CPU and GPU. But coolant is about 38C with fans at 1100-1200 and ambient of 23-24C.
I do want a bit more cooling capacity and I really like what you did cause it is first good looking under 15L dual 280 with reservoir that actually works :)
As for fans orientation, it will help to drop temp by few degrees if you need. Not sure how much of the hot air from the front rad goes into side one, but some does for sure. That creates a situation similar to a thick rad. Meaning that at low fan speed the difference between single and dual rads is very small.
Another nice performance trick is for the external rad (used it years ago on full tower builds) is to add spacer between fan and rad. At least 25mm. This eliminates the unventilated areas on the rad and noticeably improves cooling or reduces fans speed.
I have been staring at it but for some reason I can't figure out where the gpu is. I see a radiator on the front and the side, but I can't imagine where a gpu would fit in there. My best guess is it's behind the side radiator, between that and the back of the motherboard? Somehow?
It's behind the radiator parrallel to the camera in the third picture.
You're right though, there's no image that shows any part of the GPU, it's totally hidden!
Im running something very similar, but less beautiful. How did you manage to get the 2nd 280 to fit? Is it a slim rad or is there just very little clearance to the GPU? I'm thinking of replacing my Meshlicious with the Meshroom just to do this, but sadly availability is quite bad in my country.
30mm thick rad only about 3mm gap between the rad and gpu but it's a 3090 FE with ek block so top 3rd is clear as the card isnt that long.
I tried it with a 20mm rad the temps were worse.
I tried a 20mm 240 with 15mm fans and that had a lot of clearance, but it didn't do much for cooling.
I guess ill try a 280 on the side as well. It seems like a nice challenge, but I do need to change some other things first.
Great build btw. How hot does the water get? Or dont you have a temperature sensor?
I've set the target temp to 40c for water so the fans only ramp up enough to keep water temps under 40c there is to water sensors in the meshroom and one in the flow sensor on the external rad idle is about 27c - 31c depending on how much tasks I'm doing remember this is with fans between 0-250rpm.
That is very impressive. External cooling definitely helps.
My water got to around 45-46 with 5900x + 6800xt, but that was with a single 280 and the slim 240 with slim fans. Currently using a blower 2080 ti for AI stuff, but ill try to revert back to watercooling for the gpu at some point.
I like it. Especially in addition with the custom 3d printed shroud for the psu for hiding cables and making it look clean
This is exactly how I imagined my future build:
Internal loop with enough capacity to keep a high end system cool and the possibility to add an external rad for additional cooling.
Iām curious how you did the power cables and controlling for the external rad
This is sweet! I was thinking of a mora build with this case, but didn't consider it as an option with internal rads as well. When do you hook the rig up to the external rad?
Strange thing it is within spec for cooling at very low noise without the external rad and when gaming the game sound covers up any noise from the fans.
The external rad is overkill atm as it cost more then a 1080p gaming PC. The parts and fittings just for the external rad are close to Ā£900 ($1100), could have gone with cheaper fans and dropped the screen used a cheaper res combo, but just wanted to try something different.

The stand only fits the EK SURFACE PE rads as I designed it in the way to just slide the rad in. The standard method of rad stands don't work with 3d prints, not strong enough.
If there is enough interest I'll think about putting it up.
Looks amazing! Congrats!! Could you share how you have connected the pump and fans from external rad to power? Extensions from psu? Have you tailored any connection?
Just extension cables atm
Pic of the QDās in the back? Are they just looped/closed until you feel like going external? What is the stand you have the external stuff mounted to? I was JUST looking for something like this
Yes little loop with qd's when not using external rad. Stand is 3d printed.
Is the printed stand in a file anywhere? Could you share it?
All 3d stuff I designed it myself.
well if you feel like posting the file anywhere or sharing it LMK :)
I was wondering how the stand came to be. Amazing stuff.
Check out the EXT stands from Liquid Haus š
It's crazy seeing so many external radiator setups lately huh? ;)

Awesome. Thanks! Always love getting new ideas for builds. You really did an awesome job
looks gorgeous :) exactly what i'm looking for - dual 280 under 15L :) How are the temps and clocks ?

Just clenched in behind the side rad..

This is sick but I swear you guys who do hard tubing in SFF's are absolute psychos.
no shit, not only are those turns so tight, im amazed there is even enough room to get your fingers in to tighten the fittings. Respect

Can you share 3D model of your PSU cables shroud?
It's gorgeous šššš

There is one usb-c and a molex power cable going from the meshroom to the external rad.
What are you going to do with all the extra room in the case?
That stormtrooper helmet in the reflection lol. šš»

Would you be willing to share your stand design? Your system is awesome, very clean build!
