Long story to this build, but it's my first time with a custom loop
I started with the base steck and air cooling with a plan to go liquid down the road:
The noise of the GPU was unbearable - in such an exposed chassis, it was louder than my 3d printer that sits on the same workbench. This made me rush the transition to water.
I ordered a stack unit as soon as they became available.
I started with the base steck and air cooling with a plan to go liquid down the road:
- Ryzen 3600 + Scythe Big Shuriken 3 & noctua slim
- Gigabyte GTX 1080 Windforce - this was VERY loud even in the original PC it was mounted in (ATX chassis with excessive sound dampening)
- Corsair 450w SFF psu

- Alphacool Eisbaer LT Solo
- Bykski GPU block
- 3/8 x 5/8 soft tubing, Barrow fittings across the board
- Darkside 240mm radiator
- Noctua fans
- 1 pair of Barrow Quick Disconnect fittings going from the CPU outlet to GPU inlet. For filling, draining, and bleeding, I pop them off and plug them into a reservoir with matching fittings
- CPU Temps: Idle between 40-50c. Load around 80c - I still need to do some voltage tuning to bring this down a bit.
- The GPU Block + fittings are too thick to close the side panel. I designed and 3d printed a set of risers that utilized the stock thumbscrews to avoid having to make a trip to Home Depot for 1" 6-32 screws. I spent about 4 hours between designing, iterating, and running several test prints before I landed on the model you see here. I'm approx 5mm taller than absolutely necessary. I may update the design and reprint to get some space between the speaker and case.
- Koolance slim 90 degree fittings, based on raw measurements will most likely still need a riser, just not as huge a riser. I will definitely make the switch at a later date. Hard to stomach additional costs on this machine, and I'm somewhat ptsd from my first attempts at filling and draining
- The first time I filled the loop, I used plain distilled water for 48 hours as a leak test. I learned after draining how poor a job I did at bleeding out air. Lesson: Having the QDC AFTER the CPU and before the GPU block puts my fill port right between two areas of high flow resistance. I probably could have saved a lot of bleed headaches having the QDCs between the rad and one of the blocks. As it stands now, I have figured out the pattern of rotating and shaking the machine to do a pretty decent job.
- Every time I unplug the QDC and reconnect, I introduce a small amount of air into the loop - this has to be factored in and the air needs to be agitated enough to go up to the rad
- The Alphacool pump is a lot weaker than I thought it would be, but it does the job. I originally wanted the Swiftech Apogee Drive II, but COVID-19 made it incredibly difficult to get - Swiftech and most vendors were sold out with no lead time. I may switch over in the future
- The Barrow QDCs appear to be somewhat flow restricting - not an issue for a more powerful pump, but something to be aware of. Besides that, they perform great - only lose a few drops of water, if that when connecting/disconnecting
