I have a MSI HD 5670
and I was thinking about removing the heatsink and replacing the paste
I already have AS-5 thermal and Isopropyl alcohol from doing CPUs
and i was wondering with modern cards is it worth it?
I do overclock the card heavily from 775 core/1000 mem up to 900 core/1250 mem
I used to do it in the old days with my cards (example 7600 GT)
but I was wondering with the new cards nowadays
is it worth the trouble?

If you already have the paste and are comfortable removing the heatsink then by all means go ahead I'm sure the manufacturer didn't use AS-5 when they put the heat sink on. They also don't do a very good job of spreading the paste on the chip. From what I have seen when I have removed varius heatsinks even the best companies just put a dab in the middle and screw it down.

I was thinking about since to fit the card in the Dell
I had to cut the dual fan assembly in half (Twin Frozer)
and use just one fan on the heatsink
in a 70F room it is at 45C at idle
which seems a little high to me
it will max at about 70-75c under load (furmark)
so it isnt outrageously bad temps
but I am trying to OC it hard
I can get it to 900/1250 but doesnt stay stable (stable 880/1200)
so I think I will do it
since a few C cooler could get me my OC I want
I know it is silly but without voltage modding the card
900/1250 would be one of the highest OCs on a HD 5670
I have seen on the OCing forums for the HD 5670
I would kind of like to see if I can do it
the sink looks pretty simple to remove

Thanks for the quick reply
