I'm back with a new thread ! I hope that moderators won't mind that because this one has no connection with my latest one so, I have the gigabyte 9800 pro 128mb/256 bits and I wish to apply an additional heatsink on the back of the card the only problem is that I don't know if I can damage the card (what I want to say is that on the front side it's easy to install because the heatsink can be glued on the core itself - that black thing under the cooler - but that black thing doesn't exist on the rear side of the card, so is it safe to glue the heatsink directly on the circuits of the card ???) I hope that you understood what my poor english wants to say...) after telling me if this operation is safe, please tell me if it's necessary to apply some heatsink siliconic compound on the back side of the card too, or using only glue would do just fine ?? and by-the-way, what kind of glue should I use (anykind is good?)?? thanks again for your help and waiting for some advices !!!
