Yeah I have Hot Spot but no VRAM temps on my 3070FE in any application I've used yet.
On another note while not always the case - some of what I thought was the GPU fans spinning up during gaming with my 3070FE wasn't in fact the GPU... I had an old laptop down behind where the PC was which was in a low power state used awhile back for as a remote endpoint for a project and mostly forgotten about... seems a recent Windows 10 update (coincidentally about the same time as I swapped out the 1070 for the 3070) was causing it periodically to spin up aggressively for a few moments

it happened the other day after I'd turned my PC off which was a WTF moment LOL. Stupid Microsoft dunno why they can't seem to get anything right - was working fine on an older version of 10 and 7 before that.
