Hi,

Can someone please check for me or can Bob Cat confirm, should the HDR's Hard Drive Caddy fan spin all the time or is it thermally controlled.

I noticed on my new HDR that the Hard Drive Caddy fan isn't turning (when I looked when it was 1st switched on).

It's a guess but I imagine after the fan noise problems with the 9150/9300 freeview pvrs that they use similar firmware to spin up the fan if required

It may be similar, but doesn't look to be the same in operation, if White_Knight's observation is correct and if typical of other HDRs.

The 9300T fan does spin up for a few secs on startup, then it's thermal controlled. I've never had my 9300 fan come on after the initial spin-up, since installing the new firmware.

Rgds.

It does indeed use smart fan control by measuring the internal temperature.
