I have a FirePro V9800P (passive cooled) GPU on my i7 CAD workstation. The card has always run hot even though I have fans running very close to it and very good case cooling. Recently it has started to overheat on occasion and shut down. It will reset itself following a cooling period and I may resume my work. I would like to replace the heatsink with a active cooling fan setup and need advice on aftermarket (or OEM) fan compatibility. I also believe that the thermal paste may be an issue and that will of be dealt with during the fan modification.
