Whewee, thanks for the reassurance people. A thin coat is ALL it got. I went to work and left the computer on like I normally do (24/7 actually with the daily restart of course) and when I got back 7 hours later, I checked the temp which was bouncing between 37 and 38. It's a 2.0 Celeron, thought it was in the specs below but thanks for the reassurance regardless.
Where I really f'd up was thinking that there was no thermal tape or paste, and when I was taking the heat sink off, it felt like it was stuck and after a good pull it came off, processor and all!! You know how there is a small lever/locking arm for the processor socket, well, it was in the lock position still (or course) and I had bent up about 8 pins. I was kickin my *** for it. I VERY gently straightened them back out with a tiny screwdriver praying the whole time that one of the pins wouldn't break off. Thankfully none did. I would really have kicked myself in the *** if that had happened. Anyways all is well and it's running just fine.
