Replace the Heatsink with an Heatsink using in Audio Amplifier, add in some
heatsink compound. Or add in a extra 5" fan, blow toward the CPU.

The Cyrix heatsinks are terrible.  Or at least every one I have seen
has been totally inadequate.  I tried them, and gave up.  The machines we
sell with Cyrix chips get set up with a big monster heatsink and a fast
fan on top.  Totally eliminates any chance of putting a full length card
in a couple of slots, but that isn't normally a problem these days.

The PC Power and Cooling fans work great on the slower chips (and I use
them on our Pentium systems, well, and when we used to do 486es too..)
but they don't move enough air for the 166/200 chips.
