My GM5472 (AMD Chip) has been running very hot over the past few weeks - over 100 degrees C! I've cleaned the fans out and now have a fan leaning against the box, which keeps the temp down. Question is - the system is running extremely slow. I did all the normal checks for viruses and RAM issues, no luck. It's slow both on and off the net. Are these things related? What can I do?

-try adding additional fan in the casing -in adding fan make sure that you have a blower fan and a exhaust fan where in air can get in and out inside the case.
-add thermal paste/grease between the processor and the heat sink. it is often used to aid the processor's thermal or heat transfer via heat sink. -you can also add blower fan in the chipset of the motherboard -you can also add heatspreader in the memory. -check the power supply if you are getting enough power -having too much power may result in over heating and may damage the devices -having less power may result slow system and bad performance.
