Bem The P1 has lots of space around the engine and air can exit under the front  wings so P1s don't tend to suffer so badly with overheating, in fact when I had a P1 on the road I could manage without a fan  most of the time. The exception was when returning home to London in heavy traffic. Then I would fit the fan belt on loosely and although it slipped it sufficed.
