Your temps don?t sound right. A stock 1.4 Cel-T at default vcore and with the retail hsf should be well below even 40C at load.
I have a Celeron-T 1.0A @ 1.33. At stock vcore (1.475v) and with stock cooling I run ~ 32/35 idle/load with no case fans.
I would probably generally want to keep my temps below 45C with a the P3 based cores like the Cel-T.
You can do the ..."finger CPU temp test? ? to check the temp of your HS (no-joke). Basically a HS will become too hot to keep your fingers on it around 50C. If your CPU temps are really running close to 50C, that HS should feel darn HOT.
Edit: Add, at 35C, my HS only feels midly warm to the touch.
