Dual E-Fan power switch or no switch?

[Drakelee]

I'm in the middle of installing a new mishimoto rad and ISIS E-Fans, I had my last E-fan on a constant (always on) but I only had one, now I have 2 I am thinking maybe I should hook up a simple switch to turn one or both of them on and off. What do you guys and gals think?!

Both constant
One constant one adjustable
Both adjustable

Cheers

I spliced one can into the factory and then ran the other on constant

E-fans are not designed to be on at all times...

Get a thermal switch.

You can buy the factory thermal switch for an 89-90 S13 still in the hose from Nissan. I use one for my e-fan and it's worked like a charm over the years.

I dont understand why people wire switches into fans. Thats incredibly lazy and not needed. Why not just wire it up to a relay or thermo switch? Better yet why not use a fan controller?

Theres no point in having the fans on at all times. Hell mine only come on when the cars been sitting for 15-20 minutes when its hot out.

[Drakelee]

I had the old wired to the ac relay, but with my rb swap I elimated a ton of s*** so now I don't have a lot to work with.

[Drakelee]

Currently, I am tapped into the ac relay, the fans come on by themselves after about 10mins but then don't turn off. Therefore I was going to use a switch so they don't constantly run.

Thermal switch and relays or a dual fan controller. Or put the OEM fan back on because it moves more air anyhow.

Looking for a DIF controller, everyone seems to be sold out.

I just wired mine up to switches with relays, can't justify the money for a fan controller. Was planning to just use the stock clutch fan but the shroud wont fit with a koyo (even though they say it will)

Weird, mine fits.
I've never heard of someone having a problem with the stock shroud on a Koyo.

[SX APPEAL]

Yeah idk, I squeezed it in there (hehe) and the fan rubbed the shroud badly, maybe its different for S14's?

Or maybe my rad support is slightly out of line, the car was wrecked at one point.

[Razi]

Hmm.
Could be anything..

But anyways, ditto what PAHC said.

Thats what im running and other then the hell of programing pain its grate.

Try enjuku they usually have everything in stock.

I used something like this



And used a Altima fan temp switch wired as a ground side switch to a relay.

The other fan was switched on a relay also.

I am also running the ISIS fans and will be wiring a thermostatic switch + relays in for the fans. I picked up the switch at Advanced Auto Parts for $28 bucks (part number 226206). It turns the fans on at 185°F. It comes with 1 relay (30amp max). You will need a second relay for the second fan. The switch will trigger both relays though, or you can run a switch to the second.
