I have a gateway MX6433 laptop, AMD Turion 1.63Ghz; 1.00 GB Ram; 32 MB Video; WinVista Ultimate; --It has major heat issues. Normally the core runs at 189*F at full use it runs at 210*F. I keep the acess panel off to help the issue. The hard drive is fine at 100*F. However you can still cook an egg on the heatpipes. Its also roasting my nuts.:x: What i do when gaming is put it on a frozen ceramic floor tile but this isnt very convienent.
You could always browse through here for a new heat sink. http://www.excelcomputerinc.com/html/xlsearchsink.asp Or buy one of those cooler pads. Newegg.com - lap top cooler
