Reduces overall heat content in the box? (definitely!)
Anyone want to speculate how many watts of heat here (80-90c * 4-6 chips?)
Perhaps improves power quality? (Guessing yes, will know more after I try).
With all the precision stuff going on here, this shouldn't be that hard for many boards. However there are many it is impractical w/ such as mentioned above (small chips) and where they are split up.
Fortunately mine is one of the ones I think will work w/ this

. Time will tell....
