On second thoughts, a bare chip is never going to work. Assuming 10 W/k.m^2, that's only 1 W or so that can be convected away for a heatspreader temp of 100 C & 20 C ambient (& 1.5" square heatspreader). I could see a massively hamstrung BR taking 5 W, if it only had to update the bios (and not boot windows), but cutting it down to <1 W (safety factors and all, and taking account of thermal resistance of the heatspreader) is a big ask. Custom silicon that can just rewrite a bios is probably possible at that power level, but that's far too much effort for a goodwill gesture that'll be mostly forgotten in a couple of months.

), the aluminium coolers of fail actually did a perfectly good job of keeping a processor at a sensible operating temperature. They were just incredibly noisy while doing it. I was impressed by the wraith cooler's noise profile when I built my step-son's Ryzen upgrade at Christmas though - it's a lovely bit of kit.
