Recommendations Don't doubt the Cirrus7 Incus with Ryzen 7 8900G!
I bought the extreme edition in January this year and this is an outstanding and very stable machine. Very acceptable price (still) with the ridiculous current hw prices. When I started running local LLMs I noticed specifically RAM was getting warmer than I liked, sometimes going well over 60 celcius (but still way below thermal threshold). Solution? A big ass 140 mm fan on top, with a USB voltage regulator, blowing down with 600 dead silent rpm, ridding the chassis' massive cooling fans from heat build up. Result? 2 hours of local LLM carnage and the RAM temperature stays well below 50 celcius with an occasional peak of 51, 52 degrees. Soc: between 25 and 30 degrees under normal load. Network chip: before minimum 52 always, after 38 max. SSDs, from 55 to 40.
Overall the fan improves the heat profile massively, dropping components temperatures between say 15 to 25 degrees. Fan and controller? 22 euros!
