I think that the best solution is to remove the fan as well. It's only needed for very hot climates or extreme conditions such as racing that put added load on the PS motor.
The aux PS fan circuit is a marginal electrical design at best. On early build cars, the PS fan, PS relay, and the lowspeed radiator relay, are all fused by the same 5 amp fuse. Relays generally draw 0.3--0.5 amps and I measured the current draw on my Hoover PS fan at 4.75 amps at start up and 2.0 amps while running. Do the math, and the use of a 5 amp fuse doesn't seem reasonable to me. I think the fuse can blow on start up even if not clogged by debris. I have replaced my F5 fuse with a 7.5amp fuse instead.
Even with the rewiring of the PS fan on post Dec2002 build MINIs, the problem is if the fan is locked and blows the fuse, you won't know it.
I think that MINI ought to jump on this opportunity and market the PS fan as an environmentally friendly feature----what other car out there vacuums the road as it goes. MINI should have attached a vacuum cleaner bag to the back of the fan that the owner could empty on a once-a-week basis.
I think the screen is a good idea, but only if you check it periodically for anything stuck to it, otherwise it will have the effect of nullifying the effectiveness of the fan. The only drawback I see to the screen would be the task of cleaning any G4 off of it.
