Ok, I ran the sucker without a heatsink. Fans are spinning! it's running! Idling in windows: This was the hottest spot I found on the IHS. Windows reports: This is confusing. The thermometer reports 1-4c higher than core temps in 0.94 which shouldn't be possible. But then again over 10c more to the IR reading sounds a bit too much also. So, maybe.. -The TJunction is actually 90-95c? (This would actually make the most sense to me after all this) -IR reading is a few degrees off? The c2d ran absolutely fine at 600MHz and 0.7v (in bios) without a heatsink! I orthosed 10 minutes and the temp (acording to ct 0.94) never rose above 55c, pretty nice! I'm sure it would be fine up to atleast 1,0-1,2GHz at under 1v. That would be pretty sweat, running a cpu at over 1GHz without a heatsink!
