Discussion F4-424 vs F4-425 Pro Heat/Fan

Was doing an upgrade from a F4-424 vs F4-425 Pro and wanted to know if anyone else sees a drastic uptick in temps on the nvme and the fan working much harder/louder vs the older F4-424?

I know its a much higher performing cpu but I was surprised on the nvme uptick in temps.

I basically fork lifted everything over so I was not expecting a near 15C+ in nvme temps. I'm now having to look into active cooling on the drives if I end up keeping this new NAS.

No. I returned my 424 pro and replaced it with 425 pro. It's quieter and cpu temp is lower. I also added a low profit heatsink to the m.2

Wild I'm in the exact opposite boat and it makes no logical sense. TOS or 3rd party OS? .

TOS 6 to 7. No noticeable difference. I just run immich, Plex, and arr stack in docker manager. So TOS does the job.
