i was not worried about the fan blades hitting the core. just when the fan's kick on iam worried about the mounting straps going thou the core messing up the fins i read that on certain e-fan's you have to worry about this.
the two 10 fan will be closer to the core then the stock fan was, do you think this will effect the amount of air they'll pull thou the core.
the carbon sheet or metal sheet if i deiced against carbon, will bolt to the rad using the stock mounting holes.
i was thinking of some thing like this.
can you post pics of you setup.
iam just looking for input before i start spending money, rather not build it then mess up my motor you know what i mean.
