Then again, that's all probably a huge waste of time and you should rather implement an engine misting feature which lightly mists the engine to shed more heat  |
Unfortunately, the DME controls both the coolant fans and the engine bay fan, which is why they are so hard to alter the on/off temperatures. But because they are controlled this way, a Porsche diagnostic tool can test and even activate them at a keystroke, which makes trouble shooting a bit easier.
