My current build just died on me, and I will likely have to replace the motherboard and the proc, which means tearing down my loop. In order to ease maintenance, I would like to go to a double loop system, with a simpler loop each time.
What I have currently :
- 6900K @ 4.2 + 2x 1080 Ti
. The whole thing was running super cold, I don't think the GPU ever ran hotter than 40°
- EK mobo block + 2x waterblocks for the 1080Ti, with a parallel block bridge
- single loop with a 450ml res, 2 pumps in serial (achieving roughtly 0.9GPM, but no more)
- 3 rad, in serial (Hardware Labs Black Ice Nemesis GTX 480, a GTX 280, and a GTX 560)
- a flow sensor (Aquacomputer flow sensor with Aquabus)
My issues :
- the loop is huge, purging is is a pain even though I designed it for that (valves everywhere, etc...)
- I used passthrough, which looks super neat, but is a gigantic pain in the neck to maintain (they never stay tight, and I almost lost fingers tightening the pump --> passthrough tube
- I neglected the amount of vibration the pumps would generate, and I didn't use the decoupling screws very well (too tight), so the setup vibrates at certain pump speeds
- despite having a SMA8, the case is crowded (especially the lower chamber), making any change tedious
- the dual GPU setup is less and less needed, and is probably killing my flow
What I like to do :
- Single CPU loop : CPU bloc --> GTX 480 --> 150ml reservoir + pump attached under (a 480 should be well enough for a Ryzen 3900X)
- Single GPU loop : GPU block --> GTX 560 --> 150ml reservoir + pump attached under (the 560 should be even overkill)
- discard the GTX 280
Variant : I could get rid of the GTX 560 and use the GTX 280 instead (not sure if this would be sufficient for a 2080Ti)
My questions :
- When running on a single loop, do you have concerns that if the pump dies it can damage the thing ? I have an AQ6 so I can instruct it to shut down the computer when that happens (I built the relay thing so it is equivalent to a finger press on the power button), is that a sufficient protection ?
- would a single pump be OK to drive those loops ?
- how to fix the pump+res assembly so it doesn't vibrate ?
