P775TM1 RTX3080 Chinese Air Heatsinks out of stock - examining alternative options

[harkaz]

As of a few hours ago, it appears that the custom air RTX3080 heatsink for P775TM1 is no longer available - only the air/water version is now available: https://www.aliexpress.com/i/1005007688521117.html 

Well, it was overpriced anyway. I am waiting for a RTX3080 to arrive within the following days, so I am exploring alternative options.

 

Are there any measurements-detailed instructions on how to modify the current 31-P77FN-401 heatsink (i.e. by drilling)? Any other options for heatsink mounting? How bad is it if I do not use any screws on the GPU side? If anyone knows of a modified 31-P77FN-401 heatsink that is compatible with RTX3080 and is available for sale within the EU please keep me informed.
