8800GT voltage mods

I have RAM heatsinks installed on my card. The RAM doesn't get hot anyway because I didn't increase the vDimm.
The stock cooler had just contact to GPU and RAM with pads. Other parts of the frontside weren't cooled by it. I just have a 120mm fan below the frontside at the bottom of my chase to blow cool air from outside onto the graphics card.
The back of the card gets really hot because here is no nearly no airflow. But these parts there had already no sinks installed with stock.
But you are right, maybe ill get some small sinks on the mosfets

When I said 'RAM sinks' I meant it generically. I used 'RAM' sinks on my MOSFETS, but I guess it would be better to just call them sinks.

You're right that the RAM doesn't really require sinks, b/c vdimm is low. However, the PCB will get hot, and through conduction heat up the RAM.

On the reference design the MOSFETS are on the other side of the board and are cooled by the stock HSF. Since you have a non-reference design you are going to have to adjust a little bit to compensate.

The entire PCB gets pretty hot when you start getting the volts/clocks up there so it is good to get sinks on anything you can...especially components that are hot enough to burn you. Also, rig up some fans or get a PCI fan card if at all possible.
