NVIDIA GeForce RTX 4090 Has Allegedly Been Liquid Cooled to 20°C Using a Household Air Conditioner, and a RTX 5090 Is Next

I'm kinda surprised Z didn't just go straight to a split duct unit AC for his overkill build like this.

I've long thought about doing something like this. It's a bit overkill though for most of us but still fun to think about. I'm not kidding that everytime I walk by one of those cheap desktop minifridges at Walmart that I wonder about somehow adapting the compressor to a LC setup.

You will burn up the compressor in those real quick.

They make 4U rack-mounted water chillers that do what you want. They're purpose built for it so it wont burn the compressors up on them.

Yeah but they cost $$$$ whereas I can get those fridges for about $20 each in June when the local college kids are moving out of their dorms.

You'll be buying them every year to replace a burned compressor.

This aint new. There are guys in Australia that have run their loops into underground vaults because the ambient is 50F.
Using an AC unit is certainly unique though.

The great thing about college students is they keep coming back

It's a bit more sophisticated than wat J2C did and more performant, but jank has it charms too
