Simple question here: Should a CPU heatsink (486DX2/50 or DX4/100) be able to handle the heat from a 1W LS being driven at or slightly above ratings? The star boards are going to be mounted to the heatsinks with thermal pads which claim a thermal resistance of 0.05DegC/W, can probably arange a fan to fit to the heatsink if required.
This is for bench or fixed use, rather than in a flashlight, to the heatsink isn't going to be in an enclosed space or anything (Most likely on top of my wardrobe).
Heatsinks to be used are here: One already has a red/orange LS fitted (The one that has wires coming out of it), was being run earlier (at ~200mA), and I wanted to be safe.
