How do you expect to evacuate heat from the heat sink without air flow? This is heat transfer 101!
In my first post, I aimed a 12cm fan (running at 7v) at the PWM heatsink, which reduced the temperature at load to 85C.

There is also an exhaust fan (12cm) directly above, as well as the PSU (again 12cm and exhaust). There are also a further two 12cm fans exhausting air near the front top of the case.

It seems that the PWM area just runs very hot on this board. I've read reports of people who manage temps of 65C on load (with this board), but I can't see how this figure can be achieved unless you point a delta at that area.
