Chilled water + Full-cover GPU Blocks?

[NattyKathy]

what it says. I got my hands on a pair of of PowerColor LCS 6990 which are good for HWBot, if not for gaming (tho I am gonna sample some old gamez on 'em for funzies)
I think they'd benefit from the ole "toss the rads in a bucket of icewater" for benching but the idea of having slabs of chilled copper all up on the PCBs has me worried about condensation.
I know people do run chilled on full-cover blocks, what's the strat?

I keep paper towels near by and minimize the run time so you don't get too much condensation build up. (How I benched my 980ti)

Otherwise, you pull the blocks, seal the PCB in clear nail polish. Reassemble. Then wrap for insulation the card and tubes. Which all this is a lot of work. Maybe for a more permanent fixture.

Or, pull the full cover blocks off, and retrofit a cpu block to the core and air cool the memory. This is much easier to maintain longer chilled run times and typically how I run cards with poor air coolers or just want to get more from the GPU.

Good Luck!

Ok that's kinda what I thought, gotta seal the whole PCB aside from the cores/mem/power stages that need active cooling.

My other GPUs I do have on core-only blocks and yeah that has worked for past icey runs. Much easier to manage condensation when only a little of the board is covered! I don't really feel like converting these to hybrid though, the stock blocks are so nice lol

Yeah not fond of the condensation. Most cards I don't bother chilling. Just depends on what power and v-core adjustments I can get before I make that decision. If it seems like a bad leaker, probably will respond well chilled
