MacBook temperatures :|
My aluminum MacBook reaches extremely hot temperatures and the summer is still to come. 
All the temperature were measured by iStat pro. In normal CPU usage I get 60ºC CPU temperature, but when I turn on my virtual machine the CPU temperature can go up to 84ºC and the processor thermal specification is 90ºC! 
Above there is a list of CPU temperatures and respectively fan exhaust rpm:
84ºC – 3265rpm
80ºC – 2427rpm
78ºC – 2004rpm
40ºC – 2000rpm
There is another list of the max and min temperatures achieved by all components:
HardDisk : 33ºC – 17ºC
CPU A : 84ºC – 32ºC
Enclosure Base : 30ºC – 17ºC
Enclosure Base 2 : 30ºC – 17ºC
Enclosure Base 3 : 30ºC – 17ºC
Heatsink A : 72ºC – 30ºC
Heatsink B : 60ºC – 25ºC
Northbridge 1 : 55ºC – 26ºC
I already report it in Apple Discussions, but still no official answer. Is it supposed to be normal?
UPDATE: I found a application (smcFanControl) that allows to control the fan rpm, so I increase the fan rpm and the macbook temperatures decrease significantly 
Pois, tenho um como o teu e está sempre bem fresco…
Este ultimo update do leopard é que não lhe fez nada bem…
O meu aquece bastante, acho que é do material. É normal que um portátil de “plástico” não aquecer tanto. No entanto confesso-me leiga nestas coisas, posso até estar a dizer um grande disparate.
