Just a quick question about my cooling system!

[S13_RB25]

Well as the title says! I got a godspeed rad with 2 12' fans! Both of the fans run off of the CTS, also got silicon rad hoses and a nismo colder thermostat! Now should I let the two fans run off the CTS or put one on a controller? Also the water pump fan has been removed!

how are they run off the coolant temp sensor?

water pump fan?

^ What that guy said. I have no idea what a water pump fan is. haha

I think you'll need a fan controller for those two fans.

You dont need a fan controller. I just cut the into the old electric connected and wired up the first fan and then I just run a inline 30 amp fuse and ground it to chassie so it runs all the time. It works great and I'm down here in south FL where is 90 and up every day and it runnings perfectly fine

You know how the coolant temp sensor sends the signal to the ecu, when it reaches a certain temp, and kicks the fans on! Also what I meant was the fan that's connect to the water pump pulley! I took that off!

Yeah that's the clutch fan as they call it and I dont one on have it on either

^ But its nowhere near the clutch lol oh well but should I leave the 22 efans on the temp sensor?

The mechanism that controls the fan speed is a fan clutch. Use a fan controller or make your own.
