I have a Toshiba laptop which fouled up in a big way recently. To cut a long story short it failed to the tune of a new main board, a new DVD drive and a new soundcard

. Luckily it was still in guarantee but it made me realise how hot these things get. So, now that I have it back I stuck some temperature sensitive labels onto the base, just to see how hot it got.
I spent the evening doing things on my laptop and I made sure it was kept on a flat uncluttered surface all the time while the labels registered the temperature
Well the hottest place registered a minimum temperature of 54oC. Is that good? The thing I bother about is the temperature of the bits inside. If it gets that hot on the outside, how hot are the bits inside I wonder
Does anyone know anything about this subject?
