Expected temps for an Intel Core 2 Duo P9400? (mobile chip)

[mikeymikec]

I'm prepping an old laptop that I was recently given to do a job for me, a Dell Latitude E4300, which has an Intel Core 2 Duo P9400 @ 2.4GHz.

The processor temps seem to range from around 45C (the CPU fan isn't running at this temp) to about 83C under sustained load (and the clock speed stays at 2.4GHz even when it reaches that temp). The latter temp always makes me a bit nervous so I thought I'd check with people here, but I'm thinking that it's probably OK for this CPU because after the processor usage calms down, the temp drops down to about 50C as well.

I've given the CPU fan a quick vacuum-clean for good measure, but in order to get very close to it I would need to open the laptop up again (it's not just a trapdoor job or a vent that I can get sufficiently close to it IMO).

Temps are fine.

Temps are fine, but a little high in my opinion. My Dell studio 1737 is meant for 35w C2Ds (had a 35w T6400 with temps like you describe). A re-do on the thermal paste (used arctic cooler ceramique, non conductive) dropped temps well on the T6400. Popping in the P8700 netted huge drops in temps. 36C idle and 74C prime. The P8700 clocks itself to 2.6GHZ under load as well, so it should be using more power than the P9400.
