I may get flamed for this, but it's hardly the manufacturers fault if people buy something then use it in a way it was never designed/intended/expected to be used and it fails as a result.
If somebody bought a VW Polo from their local dealer then entered it in the Paris–Dakar rally and the suspension broke then they posted about it in the motors subsection complaining about VW's shocks they would get eaten alive.
But it is meant to do 100% fan speed without breaking, my stock cooler needs 100% to stop throttling 100% fan speed is within spec so shouldn't cause this to happen.
