After clean installation of Lion my MacBook kept reacting sluggish, it rendered a huge usage of memory and slow release of memory. After reseting both my MacBook improved in usage because of speed and memory usage.

Heat keeps below F, even when using apps which use both CPU and video at most.

I have reset the SMC once before which seemed to work and have just done again with instant success. Just hoping it stays alright for a while this time. On a slight tangent, after I upgraded to Snow Leopard the laptop would continue to run even though the lid was closed.

This caused me much distress on quite a few occasions as it had been in a nice snug laptop bag and got very very hot several times, I am just hoping that it has not sustained too much damage. I try to shut it down now when travelling. I am running: Thanks so much for this info!

Because the fans are used to cool the internal electronic components, forcing these components to work overtime will also kick the fans into high gear.
