How bad would it be to run without a fan? As long as I watch my temp and dont let it get too hot are there any other issues? I was thinking of keeping the one I picked up and just not hooking up the fan? If I find a deal on the right radiator Ill pick it up and put it on later.. Your thoughts RC guru's?

As long as the engine doesn't overheat, no problem.
Race bikes don't use fans. But they don't sit in traffic either.
Did one of your fans die or what?

no the radiator I got to replace my bad one has tabs that dont match up to mount the fan..
