Ohhh I sorta forgot this. You modders
might want to take note of this:
On top of the Radeon VPU's there are a
bunch of SMT 608 capacitors and resistors.
they look like little fly specs. Some of them,
depending on vendor or process soldering
and placement variables may be a bit higher
off the surface of the VPU than others.
This means if your heatsink contact plate is
anywhere off flat/level against the core it may
contact the termination band of one of these SMT
devices. This is a bad thing and may very well be
the reason why some are reporting fryed VPU's
after various HSF mods.
This may be the reason the ATI designers had to
use the spacer in the first place, to keep any warped
heatsinks from shorting out the SMT devices
that were higher than the core on early units before
they could get lower profile components.
Here's the fix I used. I got me some circuit board
repair epoxy and epoxied over every one of the
devices on top of the VPU to insulate them against
contact with the heat sink plate just in case.
Super glue gel (like loktite 4205 prism) would work
just as well. Just a *little* dab spread over top those
devices and allowed to set up. Don't try regular super
glue as its low viscosity will flow it everywhere. You
want the Gel type so it stays where you put it.
