I have a bfg fx5700 (gpu465/550ram) gcard I would like to replace the hsf but have found bfg do not use the reference mounting holes that the fx5700 does It looks like the 5700ultra pcb but i would like to know if anyone has had similiar experiance or has succesfully replaced the hsf on this card I now have a useless arctic cooling nv1 cooling kits http://www.arctic-cooling.com/vga1.php Will the nv2 fit ??? or is there any better advice ?? FYI: this is what i want to replacent (it is no bigger than the gpu) http://www.bfgtech.com/fan.html and this is the very boring respsonse from they're technical support: "None of these, as removing, or modifying the cooling unit on the video card, would viod the warrenty of the card. For the most part, the stock cooling that comes on the card, should be sufficient. in the event of failure on the part of the fan, please call us, so that we can setup a replacment, or repair of the video card."
