Hey there! :3
I’ve modded my Zotac GTX 1070 mini with electrical tape, in order to prevent it from running into the thermal limiter. This mod also includes modding my SFF ITX case, a Cooler Master Elite 130.
I’ve also documented it on my tweeter: https://twitter.com/platymew/status/1231567912227479554
This is what i have:
and the following is what i made out of it…
Unblocking ~1/4 of exhaust capacity
Building airflow dams, in order to restrict intake air to mostly cool(er) supply from outside
taking care of the bottom
and the top
the front and rear
I really want the air flow THROUGH the fins, and not just take a less resisting path!
Here’s an example of the card, mounted in the case, without the lid on
And this is my result - no thermal limit anymore! 
That’s Metro Exodus, on Steam, noVM/bareMetal, Win10Pro, 1080p-auto-ultra, on a 120Hz VA monitor via DP, 16GB DDR3 RAM.
