Actually its bad for me. Means the $1,100 worth of thermal pads I purchased while probably outstanding alone are being beat up pretty severely by the convection cooling which was free as it was DIY labor only.. The pads would've been great without convection but not to the same extent. If I was starting over tomorrow I'd do convection only. Conversely if I wasn't doing any convection provision I'd do the high-end pads. I had no idea the convection cooling would walk all over the thermal pads like they (apparently) have. One other convection-related trick I'd do is mill a few holes at the rear of the top at an angle to pull more cooling air between the top and the underside of the primary PCB. Hindsight is always 20/20!
