That's cool, can it work without heatsink in your opinion?
My k6-3+ could run at 200 mhz and v1.3, the whole system consumption was under 30 watt.

It’s worth investigating just how little cooling it requires at a range of low voltages and speeds.
Never had an embedded K6 variant before so I don’t know if AMD changed anything internally regarding power management.
In my experiments there is only one socket 5/7/ss7 cpu that could reasonably potentially be run without a heatsink and that’s a tillamook. (Under specific low volt/clock settings)
But a 2+/3+ is a close second.
I in fact have run a tillamook for some time without a heatsink.
Underclocking and undervolting help a lot
