Thermal throttling no where near thermal limits

[Chronified]

I have an Asus Dash F15 with a 3070 , it was a gift so there isn't much to complain about, but I've noticed some quite odd thermal behaviors. 

The 3070 is configured to an "85"watt TDP on the product page, but the time it spends at 85watts is incredibly seldom. 

 

It seems the GPU is thermally limited to 62c, any time it touches 62c it drops down from 85w to ~67w, and if you restrict the cooling a little bit so it touches 62c again it'll drop all the way down to 55w.

Since the GPU isn't heating up past 65 there isn't much chance for the systems fans to ramp up past a hum on any of the silent/default/turbo modes. There is absolutely 0 user controllable fan that I can find. I know it can spin up much faster because I've left it on my bed for a few minutes and the CPU got a chance to heat up enough for it to scream.

 

I've always loved Asus products and have been with them since the mid 2000s, I absolutely hate complaining against them but this is a bit much.

Any suggestions would be great.

Unfortunately this is very common.  My Ryzen 2500U has the same issue except its more predictable in that it will run full power for 10 minutes then clamp down hard.

 

I'm not sure why, but my guess would be the power delivery VRMs are running a lot hotter than the CPU/GPU so the power limit gets cut.

What's really frustrating is I've never once seen the specifics like this advertised, so you know what performance you can get under load vs sudden bursts.  Its why buying a laptop is so complicated, you have to rely on reviews.

I really hope the new LTT Labs coming in the future will address these specifics for future releases, literally anything that comes through the door gets tested as such, would be great to have a massive LTTWiki containing all the data too
