Hi all! Well, I finally built my first computer ever!!! Since I'm only 14-ish, I have lots of more time to learn and stuff, but this was REALLY fun. Anyways, small question here. First (I went with all stock, atleast for now), the thermal paste was pre-applied onto the heatsink for the processor, and it was covered. So I took the cover off and carefull put the heatsink on, locked it correctly and all, and then built everything else. Here comes the question... Once everything was done (well, other than hdd, dvd-rom and floppy drive), I hooked everything up and from the first time I hit the power switch everything ran. I went to "PC-Health" in the CMOS to monitor the temps (using an AM2 X2 3800+ with all stock) [with the side cover off]. Well, it was first at 47. Then it started moving from 47-48 and back. After that it went from 47-48 to 48-49. Back and forth. Later it went to 49-50 and the same thing, back and forth. After that I was satisfied and shut the pc off. What I'm asking is - is that normal? I didn't keep it on for long, so I don't know if it went up over 50. I'm fine with 50 (air conditioner is off, I'm sick - but when it's on, the temps will be lower), but I'm not so fine with the back and forth thing... Is it normal, will it stabilize? Or have I done something wrong? Thanks!
