I'm working right now on some modifications (I have raised the BCP 20 mm already and built a Fan beneath it {pointing upwards}), also have large heatsinks for VRM's and a wind tunnel with additional Fans on the backside of the box..... but I doubt It will lower the VRM temps below 80 C...
Later today I post some result.
If you don't care about cases and have room you could arrange the bare PCBs in a pentagon.
Set them on a 3 speed AC box fan pointing up.
I have not looked at OC yet, hope they didn't obfuscate the method.
It's cruel as an answer/suggestion but, there is a thread for previous versions OC

Be aware that beginning of thread is WAY outdated.
YMMV
