so that’s one thing I’d take into account. I work on this thing daily, like it gets a thrashing everyday for 8 hours and then some gaming also. The redundant pump is a good idea, least in my bookI’ve never had a D5 fail in 5 years of watercooling using 2 pumps. My latest build has the same 2 pumps, plus another 2 (4 total) on the sidecar of my MO-RA. The only components that have outright failed has been GPUs. I suppose this 747 could fly on 3 engines but I would re-evaluate my loop rather than continue using the computer. I don’t use it for anything important like work.
