Looks normal to me. Here is my MacBook Pro temps. Been on for 8 hours

thanks for the reply... but the aluminium casing is really hot when i touch it... hence was worried

Nah that's normal. Even the iMacs at the applestore are really hot and they aren't doing anything apart from being on AND they are in a fully air-conditioned room.

Aluminum is a great conductor of heat and on the new iMacs one assumes Apple have designed the back to act as a secondary heat sink - thus dissipating heat away from the internal components.

the aluminium acts as a heat sink, you want it to get hot so the insides can cool down.

Yeah thats true.

One of the kids at school is a total PC person. Doesn't understand Macs and says she will never buy one because how hot my MBP gets.

I keep telling her that her Dell is just as hot on the inside. You just can't feel it escaping the case on hers like you can on aluminum computers.

I even showed her the CPU temps and stuff with PC health monitor but she didn't believe me. Even though our temps were exactly the same.

So yeah. Don't worry ^^ With those temps, the heat on the case is a good thing.

I am just curious as to how things work. - If the temps. are the same on the Mac and the Dell, how does the aluminum case help things cool ? Wouldn't the temps. be higher in the Dell because it doesn't have an aluminum case to help it cool down ? I know I am missing something here, as I have not had a notebook since an NEC in 1997. Does Dell have another way of cooling their computer ?

Maybe a stupid question here, but I'm new the Macs. What app are you using to capture the temps? I just have the jinky widget that comes preloaded. Thanks!

I would guess that the Dell's fans are working harder, using up power and creating more noise. At least that's how it appears here where my colleagues use a mixture of Dell and Acer computers.

Thanks for the answer. That makes sense, my iMac is very quiet.

Thanks everyone for your views & ideas....

I'm mentally relaxed now :D
