Fedex just arrived w/ my 2200+, but my ASIII won't be in until tomorrow, Friday if it turns out that Fedex doesn't deliver on the 4th. I'm impatient, and I just want to pop the sucker in. Would it be a bad idea to run this baby for a day or two w/o thermal compound? I've got an Arkua which isn't an overclocker's HSF (IMO); it's got a huge heat sink and large fan (nonstandard size, seems to be around 70mm) that runs at low rpms for semi-quiet operation.. The HSF has a copper core that's nice and flat, so the contact might be ok. What do you guys think?
