I'm happy to report that after leaving these (burnK7, and burnMMX) running for about
30 minutes there were no problems, a slight increase in CPU/system temperature, but
within safe limits, along with a nice load average.. FYI:

processor : 0
vendor_id : AuthenticAMD
cpu family : 6
model : 4
model name : AMD Athlon(tm) Processor
stepping : 4
cpu MHz : 1327.702
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr syscall mmxext 3dnowext 3dnow
bogomips : 2647.65

note this is the "c" core chip,
256M DDR RAM,
PC Chips M830LR motherboard w/ the SiS 735 Chipset,
(note, my single-chip chipset requires no fan, unlike the VIA chipsets)

All rather well considering the CPU fan is missing two blades, and only has the little
pink patch of thermal grease.
