Personally, I haven’t looked much into purchasing aftermarket cooling for any of my graphics cards I currently run. This is mainly due to the fact that I own GTX 280’s and their very complex cooling system. However, on my spare 9800GTX+, cooling of the RAM and power management chips aren’t so important, as they don’t get very warm, even when left exposed to open air. Keeping the core at a lower temperature for F@H does help to keep the overall temperature of my room down, because we all know NVIDIA cards tend to run a fair bit warmer than their ATI counterparts.
