Going back to the discussion of thermals. A new pi 4 firmware update is currently in the testing phase which has reduced the power draw and heat of the entire board by tweaking the setup and dropping the power draw of the VL805 controller considerably

It doesn't prevent throttling w/o a heatsink completely but reduces the overall heat of the board and the power draw and by extension makes it take significantly longer to begin throttling. I wonder if this will allow a more potent overclock to become viable?
