Benchmeet Denkendorf 2026 — thanks to Bastiaan for the company, the LN2 support, and the accidental beer sacrifice to the benchmark gods :D

I thought 9xxx is soldered. 72* celcius with ln2 seems crazy.

We sure had fun. I didn't prepare anything so just packed what was laying around and that happened to be X299 and some random ram. YC was just a single run to see if the system was running properly and the pot was only at -10C. I'll do YC on Chiller when I get some time ;)
