Water cooling loop upgrade

[B4Quattro]

Hi together,

 

I just want to share my recent wc loop upgrade with you. My previous build log can you see here:

I used a plate heat exchanger to connect a second cooling loop to improve the cooling capacity. I used insulated soft tubing to connect the secondary side of the pwt to a Mo-Ra 3 360 in our unheated, but insulated attic.

Now the water temperature stays at ambient, or 1°C above when playing Cyberpunk 2077 and the system puling aroung 400 - 450 W power.

 

 

 

 

 

 

 

I'm planning to cool my PC and the room it is in with some underground geothermal collectors for the next summer :D.

Looks good! Did you notice performance improvements with the drop in temps?

 

I'm working on a second loop with similar intentions: 

 

 

Little over the top in terms of capacity (60 plate) but might as well have too much surface area than not enough. The winter will act as a natural chiller here, so I will have the second loop going outside under the door jam where I can keep everything insulated and do it and not compromise the R value of the door itself or a nearby window. Outside will be an automotove style radiator converted to G1/4 threads, but as you can see coming off the water to water heat exchanger, just stainless steel barbs. 

 

The first loop already has three pumps. One D5 and two freezemods that operate both before and after the major restriction in this loop, the heatkiller IV.

"Did you notice performance improvements with the drop in temps? "

 

unfortunately not much. I think the gpu clock stays now more stable between 2085 and 2100 MHz. It's currently around 16°C in our attic, maybe this isn't cold enough...

For connection, I used some G3/4 brass caps and drilled G1/4 threadings inside them.
