I have a AMD Duron 800Mhz and it overheats.

FOXCONN 748K7AA
768Mb Ram
WD 40GB HDD Master
ST 80GB HDD Slave (68F)
AMD Duron(tm) processor (160F)
eVGA MX440 64Mb
Samsung CD-ROM
Sony CD-RW
WinFast Chipset (23F)

I have a good heatsync and it is clean.
My CASE is also open most of the time
To the tuch you would not say the heatsync
is hot but the bios says it runs at around 70C.

Could it just be my sensor on mobo.
i dont know. please help me.benphelps..... Don't you have a coolingfan on the heatsink ?

dl65 benphelps,
70c is not too hot to touch but HOTTER than the CPU should be. If you don't have a cooler on it, you should get one.
You also need to have cross ventilation in the case. Leaving the case open will not enhance COOLING, it will cause the internals to run hotter because the air is not exchanged.I do have a cpu fan and it runs at around 4500RPM and pushes a lot of air through the heat sync and the fan on my graphics card KEEPS it cool i have a fan blowing on both of my HDD's and two fans in my PSU and a fan blowing on my Wireless card BECAUS it gets a little hot so i dont know why my CPU gets so hot.http://www.gen-x-pc.com/cputemps.htm
