My little brother owns this notebook and it get rather hot when used. It has a Intel Celeron 575 running at 2,00 GHz and a Intel GMA 4500mhd on a Intel GL40 mainboard. It reports that it runs at 60c when idle, but it feels very hot when in use. Even my own system runs cooler and it includes a ATI Mobility X1600 that can get a little toasty when in use. So, any cleanng tips?
