The va0 have a different system cooler for sh4 and pvr ?

i have done some horrible things to the internals of other gaming devices.

It normally turns out well though!

I removed the resistor on the bottom (r331) instead of lifting the pin on the chip. it is much easier to solder to and less risk of breaking a pin.

The VA0 has a single blower cooler for both heat sinks with a metal fan and heatpipes, i may try and push past 240Mhz ( maybe 270Mhz?) when i get a chance to work more on it. need to order different oscillators and copper shims the appropriate thickness to replace the cooling pads also might add some extra fans.

I have some decent Va0 pictures for who may want to see the overall internals.
