So I noticed my upper GPU (Sapphire 7970 Ghz vapor-x) ramping up in temperatures lately (up to 70C) whereas it never used to go above 65C. Then I noticed that the second fan wasn't spinning so I thought the fan was dead (2 months after warranty expired :bang I was about to place an order for some replacement fans and TIM, but then I decided to do some more testing. Turns out that after the temp reaches 70C, the second fan does turn on and eventually temps go back down to around 61-62C. Now I have no idea how this threshold has been changed because it used to kick in at a lower temperature. TLDR, is there a utility that can change the temperature threshold at which the second fan kicks in?

Fans would turn themselves off while idle and the max temps is 65 degrees. Perhaps you can consider installing more case fans / leaving more room for your PC to breathe / do DUSTING inside out in order to lower temps by that 5 degrees. BTW, it's amazing the upper card is only 70 degrees in Crossfire. Don't sweat it, pal.
