Honestly throw the thing in a bin and use an old mini pc instead. Lenovo thinkcentre tiny. You can pick them up on eBay for about the same as a fully equipped pi.
Pi is 100% not suitable for 100% duty work. It’s just a toy.
I’ve had 6 so far and all have had reliability issues or weirdness. Mostly related to SD corruption, crashing or power brown out. The power issue was not solved by running them off a proper keysight bench supply.
SD cards are quite frankly horrible boot media as well.
M600 fanless is around 15W full whack and 5.5W idle (measured). The CPU in it has a 4W TDP.
For that you gain:
Decent thermal design., A decent quality enclosure, A power supply (thinkpad brick), Two displayport holes, An SATA interface (M.2 form) for an SSD, Built in Wifi, A RAM slot you can chuck 16Gb in, 2 more USB ports.
There's no competition. I paid 79 GBP each for mine (I own 3). Pi is 57 GBP bare board.
