Which BM ASIC Chip is most suitable for high temps?

Hydronics, Radiant & Liquid Heating
1

We recently tought about playing around with older S19 Chip generations.
Basically we have the BM1398BB found in S19 and S19 Pro Models which should work on up to 85 degrees. But there are also the newer Generations like BM1362-AC found in S19j Pro (pcb version / BHB42601) and BM1362-AK from S19j Pro aluminium board version
BHB42631 (also wound in S19 Hydro devices.

does anyone know some max operations temps of these chips? how stable and how reliable maybe?

i guess the max working temp. should be around the same. but maybe the newer BM1362-AK Chip is not so reliable to heat also because The S19 Hyd is normally not running on so high temps like air cooled devices?

Cheers!

Bitmain has this old document.. some chip max temps are listed https://support.bitmain.com/hc/en-us/articles/360005088914-Miner-Normal-Operating-Temperature-Range

Thank you!
sadly it’s PCB Temp just for some it’s chip temp
but good informations to look at!

cheers
