Corsair Obsidian 500D RGB Hydro X Water Cooled build

[Jules MK]

First attempt at custom water cooling loop.

 

Intel i9 9900k cooled by Hydro XC7

MSI Geforce RTX3070 gaming X trio cooled by Alphacool Eisblock Aurora Acryl GPX-N

Hydro XD5 Pump/Res Combo

Hydro XR5 280mm Rad top

Hydro XR5 360mm Rad front

4 x Corsair LL120mm RGB fans

2 x Corsair LL140mm RGB fans

Clear Corsair XL5 coolant

Corsair Vengeance RGB PRO SL 16GB (4x8GB) DDR4 3600MHz C18

All the fittings and PETG hard lines are Barrow, I likes the look of them

 

 

The Corsair X stuff is really easy to use

Temp wise while playing WarZone the GPU never goes above 60 degrees (was mid to high 60's air cooled)

The CPU sits mid 60's, this is close to what it was previously with a Corsair Hydro X platinum AIO, show the great job the AIO's do now, they don't look anywhere near as nice though (in my opinion)

 

I might change the top rad to a 280mm with 2 140mm fans at some point

Also the GPU block is from Alphacool as Corsair don't make one yet, I might change it if they do (anyone know if there is one in the pipeline?), it would be nice to have iCue control all the RGB

 

RGB on - not for everyone but I like it.

 

RGB off - The blue/black GPU cables are on order, the yellow has to go!

 

 

Any thoughts or suggestions on how I can improve are welcome

It would help knowing the water temperature, to know how efficient the loop is.

Almost 60°C on a watercooled 3070 is pretty hot, so there's room for improvement i imagine :)

depending on your room temperature, i'd expect it to be somewhere in the low 40s with 2 radiators.

Thanks for the reply! The water temp sits at about 40 degrees while gaming or stress testing - I have not adjusted the default iCue fan settings so the fans don't turn on till the water gets to 34 deg. At Idle the CPU sits about 4 deg higher than the water temp - the GPU is with in a deg or 2.

ouchies... yea you want to make your own custom fan curve based on water temp.

With a 3070, you should be able to sustain 34°C water temp under load.

That should leave the GPU roughly 10 - 15° higher than that depending on how good the waterblock is.

 

Whatever the slowest fan speed is for your fans you can set this as the lowest speed (like 600 RPM @ 25°C), and maybe increase gradually speed to try to sustain a reasonable water temp. I usually go for 35°C max to start with.

 

If the fans are too noisy to keep that temp (like 1500rpm @35°C), allow for 1°C more (1500RPM @ 36°C), and keep tweaking until you are happy with both the temperatures and noise level.

 

That's how i usually go about it, but every PC is different, so that's just one method :)

 

If you really want the PC quiet at idle, you could keep the fans on one radiator at minimal speed, and set a second fan curve for the second rad, identical except you go to 0 RPM at low temperatures.

 

Getting lower temps will definitely get you a few Mhz on the 3070, and more headroom for OC.

Thanks for the advice. I have set a custom fan curve (well two - one for the pump and one for the 5 rad fans) a quick 10 min set up and now am keeping the water temp max 34 degrees while the GPU seems to sit around 53, Going to test properly later
