So I set it up last night and am currently using stock cooling while waiting for my Ultra 120 eXtreme to arrive.
I find the stock heat adhesive to be annoying to remove from the CPU and figured I wouldn't need it much anyway, but I never expected temperatures to be so low.
This is with a Direct x 9 game running in the background and around 4 other windows open, 51% CPU usage. (Stock Cooling on the E6600, no adhesive, ambient temperatures are at around 26 degrees Celsius)
35/37 Degrees at half load in a heated room? Wow.
I may try to OC with current cooling.
