I get massive overheating on my graphics cards, the main or top card is hitting low 90's and staying at about 2000 rpm the bottom card is hitting 40-50ish and the rpm is hitting 4500! So, I was wondering if somehow the software is confusing the cards' temperatures? I have dual GTX-460 MSI Hawx Talons hooked up with SLI the Mobo is a Gigabyte Durable 3. To put it in perspective I play Skyrim, and the card will start squealing after about 20-30 min and thus I will shut the game down to let it recover.
