I recently noticed my Umbrel Home 2024 with some erratic temps. I only have a few apps installed (bitcoin core, electrs, lightning node, mempool, public pool), and I use my Umbrel exclusively for bitcoin related stuff. I have a regular NAS for my network shares / networked computer backups.
Anyway, I constantly see temps jump from 55c to 69c (nice / I lol at that easter egg every time) to 95c where it says it’s too hot. The UH is kept in a cool place in my basement (on a wire shelf) which is a constant 60-65F with plenty of air circulation around it.
Here is everything I’ve tried to test…
- tore down the Umbrel Home as I suspected the fan wasn’t spinning or the thing was somehow clogged with dust… neither was the case.
- flashed the drive and reinstalled UmbrelOS on the UH to eliminate the possibility of some random process that got out of hand.
- setup UmbrelOS on a Beelink Mini S12 and placed it on the wire shelf next to the UH. After everything is synced the Beelink stays at a very consistent 40-50c and rarely ever goes above this.
So anyway, is this just “normal” behavior for the UH? I understand that the UH is much smaller and compact compared to the Beelink and air circulation is expected to be better on the larger miniPC. I’m not overly concerned with the temps fluctuating between 55-75C, but I do worry about it hitting 95C several times per hour.
