I have finally got these two bad girls reasonably stable at asic temp of 68c and power module at 44c/45c
Note the evo 212 coolers are lifted 15mm up. This has reduced the cold airflow over the power modules.
after I used the "Hairdryer Mod" the boards would restart, but the temp. at the power modules would slowly fall.(eventually crashing again)
The cardboard cover is (hopefully) holding the temp. in the power modules and the cold air from the evo is deflected upwards.
The secondary fans are controlling the airflow under the boards, if I move them around then the temp. does change.
