I recently Purchased a Zalman VF1000 for my 4850 wanted to keep it cooler and experiement, always fun with PC customisation.
Anyway my problems arised almost instantly when it came to removing the stock fan. The larger screws found around the card were easy to remove, but unfortunately the smaller screws on the backplate X thingy I cant remove. ( pic of card rear here http://www.ixbt.com/video3/images/re...-scan-back.jpg) The problem is that I don't know what size screwdriver is required to remove them.
I've already made the mistake of going out any buying any old set and none of them fitting. If anyone knows the screw size would be of great help thanks.
Also did I make a good decision with the VF1000? It was sorta an impluse buy when buying a 900 and trying to make the most of next day delivery on ebuyer.
