Adding GPU to cooling loop, single or dual loop?
I'm planning on putting my 2080Ti under water. My 9900KS is already water cooled with a 10W DDC / Optimus V2 and GTX280 radiator on the front of the case. Fans are push/pull on the front rad.
I have another 10W DDC and reservoir unused right now along with a GTS280 radiator, so I have the option of going dual loops or going dual-pump in a single loop. The GTS280 will exhaust out the top of the case. I also have a 6W DDC but the flow is pretty weak on a restrictive setup. GPU blocks don't seem to be very restrictive so I could consider that in a dual loop setup.
If I go dual loops adding the second will be pretty easy. If I go single, I'm thinking of going pump -> Optimus -> GTX280 -> pump -> GPU block -> GTS280.
Open to opinions while I brainstorm this. I'm not overly concerned about pump reliability so I don't care too much about redundancy with modern thermal shut down tech.
