hmm, I had considered just on the waterblock, I hadn't though about a pelt failure, I was thinking pump failure. the relays would protect against pelt PS failure.
would what the relation of temp be between block and cold plate if a pelt failed. though it will be protected somewhat since each block will be running 2 pelts.
Must think some more.
the dual pelts should provide enough protection if one should fail, I would notice the problem by the fact that the CPU is no longer running below 0C. Not catastrophic by any means
anyone have any thoughts?
