radiator help the beemers back

as most people saw i crashed my bmw and it has a small hole where the fan rubbed the vertical tubes in the radiator does any one know an easy fix aka kwik steel putty or even heat proof silocone?
im gonna remove the fan as i bought an electric thermo so it wont do it again.
Ive also bought brand new kumho excsta rally tyres only two though,i can get different pattern yokies for the same price and was thinking 2 different tread patterns may be good 2 swap between the drive and steer according to the weather any ideas ?
