Anyone come across this problem.
I have a good condition s14 alternator and if I kick my newly installed altama fans on full power for both fans the car almost dies at idle. I have a 500 watt subs and alpine speakers all around with that cranked and high beams on at I never notice any kind of power loss. as soon as i kick the fans on full with nothing else drawing power the car goes from 700RPM to about 400RPM. Massive draw on the system.
I am just blown away with the amount of power it takes to run these things. anyone overcome this problem or should i just run them on low. lol.

I have one other question about this setup as well.
I see many people using a stand alone temperature switch and probe.
When using the same thing I find that even after the car has been driving around i cant get the probe hot enough to engage the switch at all. Is this normal or dose the prob need to get really fucking hot before it engages. I dont want my car to get to the point it has to over heat before the switch will engage.
They do use alot of power but i don’t think that much. Perhaps its shorting out or something when the controller engages the fans. And the controller should only come on after the temp gauge reads more than half way. It doesn’t turn on exactly at half so don’t freak out if it takes a couple minutes for it to engage. It should also turn off just under half way on the temp gauge cause if it overcools its just as bad as under cooling.
Good luck figuring things out and there are gauges that are digital if you wanna be really pro and do it accurately.
i will check it again soon problem is its soo cold out that i cant get the engine to reach half even when driving with no fans on. it sits just under. but i figured the temp controller on its lowest setting should kick on even before i reach half… I wonder if its broken.
yea they shoudln’t be drawing that much power. Either your wiring is messed up somewhere or this is something wrong with your fans.
On my car, if i put them both on high, the battery voltage will drop by liek .2 - .5 volts, but thats with the car still runing in teh 13.7-14.0 voltage range.
If wiring isn’t the problem, maybe its just the fans are worn out and motors are at the end of their life. Good way to test is borrow someone’s altima fans that aren’t in use, plug them in using same wiring, and see if they draw same hardcore power or are normal.
