The motherboard also used mostly electrolyte capacitors and not always well known brands too. So what I did for the chipset heatsinks,is I added an active cooled heatsink to one,and a large heatsink to another. I installed new fans,which ran at constant speed to make sure the VRMs and capacitors around there had constant airflow,and modded part of the standard cooler since it would be difficult to add a new one due to the propriety cooler.
I also made sure all the cards I installed had blower coolers - a number of people who had unmodded SD37P2 systems with higher TDP parts like what I was using could have them go kaput due to capacitor failure. Mine lasted nearly 5 years until it had one or two issues,and upgradetitus kicked in and I moved over to SB.
