It’s been a while! Let us know what you’re currently working on, what exploded, what cool stuff you found, or just brag that everything is running fine unattended.
I haven’t been doing a lot, renovate auto upgrades for patches and sometimes minor updates work great so far. I got involved in my union to spin up a mastodon server soon, so there’s a new project, but I already run mastodon so it shouldn’t be much of a deal, I just need to get comfortable with the infrastructure. I also set up ntfy but only sent some test notifications and didn’t configure any app yet - planned for Element Chat.
[Meta] I’m not sure how to apply the new tags. In the recent versions of this thread, people sometimes posted about their ollama setup or the like, but I’m not mentioning AI in the post body (except this meta thingy) and it shouldn’t be much of the discussion, but it’s an open post. Maybe curbstickle can chime in to let me know if I should apply one of them.
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.
…But again, you aren’t gaining much over a 4090. A 4090 + DDR4 threadripper would be way faster than a 5090 + occulink, for many reasons. And TR CPUs are pretty reasonably priced compared to GPUs these days.
But even if you do go 5090, I’d highly recommend finding some way to shove it in the case and duct some air into its intakes. Its going to be way faster on a PCIe slot.
You could even get a riser and mount it somewhere else in the case, theoretically.
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 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
Unfortunately condensation is, indeed, an intractable issue there.
Sometimes people put a heat pump in water cooling loops, where condensation along the pipe can be mitigated with insulation, but even that’s a little risky with a 5090 these days.
Enjoy your lovely greenery!
