Cooling re-visited

I wasn't happy with the fitting of the fan on the radiator, as I mentioned last time as the screws were clipping the radiator and denting it.  My temporary fix was a few strips of duck tape as you can see in one of the following pictures, it didn't look great and there must be another way around it.  I took it apart again today and turned the bolts around, once they are tight they pull the screw head into the plastic bracket and the problem is solved.  I also turned the brackets upside down so it fits much better.
