just get a better heatsink/fan for the cpu. It won't cost too much, and it will make it run cooler. Since ur computer runs that hot it will definitely be worth it.
something like this: http://www.newegg.com/Product/Produc...82E16835118114
and then while u are at it get some arctic silver 5 (http://www.newegg.com/Product/Produc...82E16835100007
) to go with the new heatsink.
I'm not an expert in cooling and I didn't spend alot of time looking at different heatsinks so u could do some more research by yourself.
But a new heatsink and arctic silver 5 should do wonders to that temp. And the total price will not be that high.
oh, and u will need to clean the cpu from the old thermal stuff (most likely there was a thermal pad) before applying arctic silver (or any other thermal thingy)
