  Be aware that you pay a significant performance penalty for going over occulink.

  And that’s why it’s tentative. The reason I’m leaning towards the dock is that, while the 5090 will fit, physically in the case, I am worried about heat dissipation. Even now, when I fire up a moderate model and run it through some paces, I can see the temps rising fairly quickly. So, if I’m going to drop that kind of cabbage on a 5090, the one thing I don’t want to do is watch it turn into a shrink-i-dink.

    Duct it!

    I have a 400W 3090 with zero case fans.

    Its always cool, because I bought like $10 of weather stripping to “seal” its intakes against the edge of an SFF case. So it’s always sucking in ambient air:

    You can also severely undervolt a 5090 to like 250-300W, with very little performance impact. Honestly its stock speeds are kind of crazy.

      Shit I deleted my post. Yes I have been enjoying some greenery so you just have to hear me out. I have an old countertop ice maker that stripped it’s gears. The refrigeration loop is fine. Pretty wild how small it is. I was wondering…what if I provisioned some brackets on which to mount a muffin fan of unknown CFM, to blow across the coils thru several sheets of mesh of varying gauges to collect moisture drained off to an unknown location, and duct that indirectly into the computer, like a miniature Liebert server room cooling unit. I worry about the moisture tho. Constructing a desiccant wheel seems improbable. I could reheat the cool air upstream or mix warmer air in with the stream to keep the so the outlet air doesn’t stay at a very low dew point and “rewet” downstream components. Perhaps with a small filament heat coil. HMMmmmmm
