Umbrel Pro / Knots / Electrs / Nice Lenovo laptop.
Notes all sync’ed up and running great, verified at mempool.space. but…
the fan runs alot at medium to high, shouldn’t be that way, CPU draw is minimal…
Thanks, GZ (beginner)
check your bios settings
Hey,
glad to hear everything is synced and running well. 
Even with low CPU usage, Knots and Electrs can still create disk activity, especially after syncing or while Electrs is indexing/compacting data. On a laptop, that can be enough to make the fan ramp up.
I’d give it some time after the initial sync and check the actual temperatures and disk usage.
Lenovo laptops can also have fairly active fan curves…
