How hot does the yggy get?  Does it warm up the room?  Is there a fire hazard leaving it on all the time?

It doesn't get hot at all, just slightly warm on the surface. No appreciable heat added to the room. Definitely not a fire hazard to leave it on.

I found the yggy temp to vary greatly.
The case really cools the unit well,
And so it depends on ambient temp and ventilation.

My room is very warm, so my yggy gets a bit hot on left side.
Raising the unit (putting bigger feet under) did very little to cool it..
But when I had a fan nearby it cooled down to barely noticeable..!

I wouldn't actively cool it, temperature stability is crucial.

Yes that's a good point...

In my case it was a nearby fan that was cooling my tube amp on top of yggy.
It was as indirectly blowing some air around on top of yggy.

I don't think it's a good idea to cool tubes either, they have heaters for a reason. Let the stuff heat up, and gently cool naturally.

I think people worry far too much about the temperature. These devices are tested and rated to operate at the temperature they get, even warm tube amps.

WIth open backed headphones in my quiet home office HeadFi environment, an out-in-the-open cooling fan is not going to happen.

IMO
YMMV

Agreed, this is why essentially no audio equipment has fans. People underestimate how background noise can add up. The difference between 0-10db background noise is huge compared to 30db. 30db being "a quiet bedroom".
Living within a metropolitan city myself, it's unavoidable. Camping up north where it can get 0-10db at night, bigger difference than a $5k amp can make (imo).
 
One of the first things I'll do when I own a home is make an audio quiet room. I don't see any alternative in a metro city.

Just listening to Someday My Prince Will Come by Miles Davis and I enjoyed a level of detail I never have before. 
It feels like I need to listen to my entire discography all over again since upping my game.
 
It's not just the Yggy but better phones, awesome tubes etc.

What tube amp and phones? Looking for a new amp but not phones at the moment.

I have Audeze LCD2f & Lyr 2 presently, but Mjolnir 2 & LCD 3f on the way...

Ok was looking a different way to drive my Ether C's just want a good tube amp and was thinking of something different. The Mjolnir is great with them just looking for a different sound. I am at a impasse with the Ampsandsound Kenzie or Microzotl 2 at the moment. I'm leaning towards the Kenzie as it is just so smooth with the C's and sounded awesome with the Utopias as well and neither were driven by a Yggy.

Did you roll tubes on the MicroZOTL2? I'm hoping to hear DNA Sonett 2 in better (quieter) conditions. I could PM you more details as I get more chances to hear these with headphones like the Utopia. Unfortunately, I do not know anyone regionally who has the Ether.

Finally got a Yggy to complete my setup. I'm looking forward to my next stop, the KGSSHV. It's insane how clean this is.

Had to look up "KGSSHV". True Norse rather than Schiit, whoa! (Couldn't resist, Baldr forgive me).

Which Stax are you gonna drive with KGSSHV?  Currently, I got Yggy > Carbon > 009 = full bliss.
