Turns out the e-fan mounts had been bashing around and cracked the radiator. It was mounted with those glorified cable ties that you push through the veins but they weren't holding it too well and it could move around a bit. Going to make a shroud that I can bolt the fan to so it doesn't destroy it again.

Thanks. I'll message you if I get stuck.
