Can't understand my computer. It's a very simple custom built pc with an AMD 5200+ processor, regular heatsink and fan and a system fan.

Following previous advice here I've cleaned out the case, taken the heatsink off and thoroughly cleaned it. I've cleaned the cpu and heatsink base and reapplied a thin layer of Arctic thermal paste, checked the heatsink is seated properly and cleaned the fan too. The cables don't seem to be obstructing airflow.

Core Temp reports about 50C after booting and this tends to rise slightly to about 64C over ten minutes. Once I open Firefox (opens to BBC News) the heat climbs to around 72C and stays there. If I open a page with interactive flash it sometimes climbs to around the 84C mark but often goes nuts and the temp climbs up to 100C and sometimes as high as 118C. It will sometimes cut out and needs to be left to cool down, often just closing the browser will drop the temp to about 84C again. But it's erratic, sometimes it will just stay happily at 50C no matter what is going on. My other PC (similar but Phenom Processor) runs sweetly at about 45C all the time!

Any suggestions would be appreciated..

Mart.

From what you describe, my guess would be that either the heatsink is warping or damaged or it needs a little more thermal paste.

Here's some good instructions on applying thermal paste...

If that doesn't do it, the next step would be trying a new heatsink.

Hope this helps

Two other thoughts.

Is the case cool to the touch?

What is the CPU usage in task manager?
High CPU usage will cause the CPU to produce more heat.

Are you sure it is getting to 118C?
That is above boiling water temp as 100C is boiling at sea level.

Have you tried using a digital probe on the CPU heatsink?
Digital Probe = one finger (A Digit IOWs)
Being very careful since if the 118C reading is true then you could get a really nasty burn.

Another thought, Are you sure the reading is in Centigrade and not in Fahrenheit where 118 would not be a hot temperature.

Good Luck

When you say regular heatsink and fan are you refering to the stock one that came with that particular CPU?
