if you were to try to retro fit and make it stronger then the engineers desgned it to be i go along with looking at the fan itself, the screen is one way to go but also if you can find an older hydro like my 125 they came with a steel fan.
while doing my hydro fix i discovered this, i do not know if the shaft diameter size is the same but a steel fan would be stronger then the plastic crap they are dishing out as replacement parts now days.
i myself would not go with a Tanny cooler my self, it in my opinion is overworking the original problem and creating more falure points in the system. but it is your machine and you do as you want to make it fit your needs.
