Radiators

I run all my accessories off of a fused switch panel. Basically the whole car is racecar wired, water pump,fuel pump, interior fans for when it is hot sitting in staging, and lights. I don't run a relay for the water pump because its on its own circuit. I do run a relay for the Barry Grant fuel pump because it has such a high current draw and it is so far from the switch and BG recommends one also. Like outlaw said if your not running through your ignition switch you should be fine, if you are, then run relays. It lakes a lot less juice to switch a relay on then it does to power some of these high draw accessories.
