Hi,

I have several amd k6-pr2/233 processors (all on dfi motherboards, 586ipvg);
no heat problems with a (regular) heat sink and cooling fan - you can touch
the edges of the cpu, it's just warm, not hot.

Note that these processors should be 3.2 volts, not 3.3;  I have more than
once had some other board pre-configured and 'set' with the voltage too
high.  The result is burned fingers.

Hope this helps,

steve
