I have 2 GTX285 cards in SLI.  Even on non-overclocked settings, this OCCT graphics test takes the cards to 105 degrees (celsius), at which point I guess they throttle themselves back.  I have a well ventilated case, the fans on the cards are running clean and fine (and at 100% during the test), and most importantly, during use of any practical application, my GPU temperatures max out at about 85c.  How could displaying that stupid fuzzy ball put so much stress on the cards?  What is going on?
