680X RGB CPU+GPU water loop


Recommended Posts

Thought I'd post my recent 680X water loop build since there seems to be so few examples, at least when I was researching it prior to the build. Here's the components list:

 

Intel i7-10700k CPU (water cooled)

EVGA RTX 3090 FTW3 Ultra (water cooled)

Corsair Dominator Platinum 4000MHz 2x16GB

EVGA Z490 Dark KingPin edition motherboard

EVGA SuperNOVA 1000 T2 PSU

Corsair Crystal 680X RGB case

Samsung 970 Pro NVMe m.2

2 x Corsair 280mm radiators

4 x be quiet! SilentWings3 high speed 140mm PWM radiator fans

EKWB Quantum Vector GPU block and backplate

Optimus Signature V2 CPU block

Corsair XD5 pump/reservoir combo

All fittings are Corsair Hydro X series.

ASUS Strix riser cable

Grizzly Kryonaut tim

 

Overclocked the i7-10700k CPU to 5.2GHz stable and the RTX 3090 FTW3 Ultra to 2.05GHz stable and ran 3D Mark Port Royal and scored 14,317 which is pretty nice. RAM was just running at XMP settings. Running AIDA64 System Stability Test at full load on both CPU and GPU at the same time (so pushing the cooling pretty hard), with ambient at 77°F, after 10 minutes the CPU @5GHz had leveled off around 70°C (all cores) and the GPU @2040MHz leveled off just touching 60°C. Not bad.

 

Loop order is res/pump -> GPU block -> CPU block -> bottom radiator -> top radiator -> res/pump.

 

It was a bit of a mission getting all that gear in a 680X ATX case. Some photos:

Showing just how packed it was fitting all this into the ATX case..

reminds me of my first watercool on the 680x, talk of tight fits :)

the temps are not bad at all for a two rad setup with 3090 :)

 

Water in the 40 - 45° range under load?

 

I wish.

Running AIDA64 System Stability Test at full load on both CPU and GPU at the same time (so pushing the cooling as hard as it can be pushed), with ambient at 77°F, after 10 minutes the CPU @5GHz had leveled off around 70°C (all cores) and the GPU @2040MHz leveled off just touching 60°C. Not bad.

But what's the water temp?
