Agreed, I unfortunately didn't even bother to convert the temps. I figured they were high though. I have also noticed that having active flash in Safari can cause the processor usage to be unusually high.
My machine was at high temperature around 89 C when running a bunch of programs, after cleaning the cooling fan it dropped to 72 C , with smcfan control at 2/3 of the original speed. Quite a lot change with no major operation. Just wipe the cooling fan with cotton stick. I guess I am not going to take the computer apart checking the heat sink, with external cooling pad, it should be fine. Hope this will be helpful to you.
