From Mine Peon. It shows a high hardware error rate, but on BTC Guild shows 35GHs at first then slowly goes down to about 29.93GHs after 24 hours. Not sure if its a bug in Mine Peon 0.2.3a or what.

For the setup I have the Coolermaster 212 Evo with the .5mm thermal pad. Using the LGA standoffs with no back plate. Card is laying on the side so the fan is blowing one end and a usb fan is blowing on the back sides of the chips. On the bottom they are hot to the touch but not scalding. About 5-6 seconds before its uncomfortable.
What version of cgminer does MinePeon use, and what's your share difficulty? Old versions of cgminer counted one accepted share regardless of difficulty, while newer ones count shares as diff1 shares. That can make a huge difference in error rates.

CGminer 3.3.4

BTCGuild is on worker diff 32

sorry for the chopped up tables
