Try, oh well, to compile Linux kernel on it and see what happens. Or
recode some HD video. Or any other stupid, but CPU-intensive task. Or
play some 3D-game if you're on NVidia.

It's warmer because of it's metal case which is obviously a good thermal
conductor. And it also conducts the heat to the components which were
never intended to be that hot. Your spinning HDD maybe? Check it's temp.
IBM/Lenovo engineered a superb quality product which don't get really
hot outside (and inside) even under hard load and you abuse it so much.
Get the fan. Or repair the original one. It could be done. I did it. All
you need is to apply some oil.
