   Video cards and heat
  I''m curious about what kind of operations cause a video card to get the hottest. I don''t have much experience with higher-end graphics programming, but we have a club here at the university that looks at the temperature rises from certain video games and benchmarks.My gut is telling me that games and benchmarks do enough "other" stuff that the heat rise from just the video card isn''t as high as something that just sits there running intense operations through the card. So I''m wondering if anyone knows what operations might generate the most heat, so that I can try to put together a small simulation to test that theory.I appreciate any suggestions and advice. 
  [Moving this to the lounge, because you''ll probably get more replies there. Apologies in advance for any crap the thread may accumulate as a result.] ;  I don''t know why, but my video card already becomes warm from simple 2D operations, as if it''s always working at full speed even for the easiest applications.  If it''s really doing that, oh dumb nvidia you! ;  i have a FX5900 and i can definitely tell when im running something graphicly intensive, the temperature DEFINITELY rises, i dont know about lower cards but FX 5900 has a built in temp sensor. just drawing triangles really isnt what''s making it heat up so much, the lighting and texturing methods seem to be a big factor in the heat output.   ___________________-Nicholas Anton-raptor85.siigna.net;  Anything 3D (WoW, War3, etc) heats up my graphics card (R9800).  Then the intel active monitor temperature alerts get set off and everything goes to...  Anyway, I have two fans + the fan on the cpu + the fan on the power supply + the fan on the graphics card and the sensors on the motherboard (not the cpu sensor) get up to 50oC.  It's kinda stupid how the graphics card is below the cpu... as the graphics card heats up it heats the cpu as well .  Refrigeration should be mandatory for all motherboards.
