Radeon

Need another suggestion for my 9700 pro. Last week I put
on ram sinks, tweak monster brand with the arctic
adhesive, to help cool the memory on the card. I still
think the card is having heat problems. I have 2 fans in
the back blowing air out, 4 up front blowing in and one
on the side blowing in which use to blow out, but changed
it to blow in on the card. I have nothing around the
card so that I could have good circulation. Ram sinks
are on fine, but when I played UnrealII, those flashing
bars and little black lines that are in a pattern
appeared again and I had to shut down and reboot. I have
all the latest drivers and patches and played with
settings and I know that it's not that, but heat because
a tech who has done work for me before said it was
definitely heat. I do not know what else to do. A
better fan on the gpu? Cannot do the heat pipe like
Zalman's because I don't see any mounting holes for it.
Should I try a card that has that on there or a different
Radeon or maybe the FX? Please help. I have had all of
these frustrations for months.
