yep. below 30mph both fans were cycling back & forth. after 30ishmph, none of the fans turned on. and yesterday was SUPER hot here.kots1 wrote:Did you measure with Torque app while your A/C is on? A/C on may have kept cycling one of the fans.

which side is the high fan - passenger or driver side? I couldn't wait so I also bought a kit and will plan to install it this weekend:5.56 wrote:i again checked the fan, duty cycles. the low speed was constantly on, even during highway speeds. the high speed fan, was only seldomly on during cruising speeds, and was on mostly below 30mph. so thats the fan (high) that i will be hooking up the new tranny fan.
thats gonna be my plan as well.kots1 wrote:I also see 4 wires hooked to each fan. I will have to tap on each to check which wire is the +12 V unless you already figure that out.
one fan is run by temp sensor. the other goes when ac is on.kots1 wrote:I also see 4 wires hooked to each fan. I will have to tap on each to check which wire is the +12 V unless you already figure that out.
Check this out from 350z forum. just to give an idea on the combinations to tap into 2 out of the 4 wires. I thought I can just put the fan ground wire to a bare metal. We may need to run two wires - Blue (Hi+) and Yellow (Hi-).5.56 wrote:one fan is run by temp sensor. the other goes when ac is on.kots1 wrote:I also see 4 wires hooked to each fan.

1 could be low, 1 could be medium, 1 could be high, and 1 could be ground.
i will just poke around until i find the one that runs the HIGH fan circuit
have you figured out, which way is the fan's most efficient direction? take a look at the fins, and and see which direction to spin the blades to get optimal flow. and then decide in which format you want to install it (pusher or puller). you have to see if you want to create a vacuum, or to push air.kots1 wrote:Excellent work and clear explanation on the video! I got my fan last night and it is similar to yours except for the shroud. It looks like they are from the same fan manufacturer. I also did a bench test and I am also impressed with how much air it moves. I can't wait to do an install this weekend - if I get some time.
Since I will be mounting on the front side, I would do a pusher - blowing to mini radiator. Reverse polarity on mine for pusher - blue to ground and black to +12V. This is so it does not interfere with air flow at highway speeds.5.56 wrote:have you figured out, which way is the fan's most efficient direction? take a look at the fins, and and see which direction to spin the blades to get optimal flow. and then decide in which format you want to install it (pusher or puller). you have to see if you want to create a vacuum, or to push air.kots1 wrote:Excellent work and clear explanation on the video!

i still have to look to see which is best for mine.
Good question. I don't have a scientific method other than, touching the inlet port and outlet port and measuring how long can I tolerate it. The result was inconclusive for me. Hahaha! I still cannot hold outlet port long enough to conclude that the fan helps. But I'm sure having a fan is better than no fan at all.Rogue One wrote:How soon can we expect to see results posted of its efficacy?
so according to my 'figurin lol, our system runs both fans, at super low, medium and high settings. there is no wire that sends low speed, and then another wire that sends medium, high, etc. its weird. it seems like a regulator on the fans accepts 13-14volts, to accept more voltage for more speed. i couldnt figure it out. i tried testing with a volt meter, and i would find the passenger side has 2 positive, and 2 negative; both registering 14ish volts but they are grounded internally(which means you cant ground the negative wire just anywhere on the car; it has to touch the gray/pink wire on the plug to turn on & off.) i guess one is low, and one is high and the regulator on the fan itself, decides which is which.kots1 wrote:Which wire on the fan motor did you tapped into?
i did the same thing! lol thats so funny. but then i realized, we can just yank the fuse on the fuse holder, and that in itself is the thing to cut power lolkots1 wrote:I put a connector on mine that I can unplug easily
i have the wiring video being edited right now. stand by.Nice work there detective and thanks for recording the video!
I cannot tell any difference in my AC temp. I can tell that the tranny fan has a secondary effect in helping cool down the main radiator faster. My Rogue shuts off all fans more frequently now. With all 3 fans running, the air flow is all sync in the same direction so that helps drastically. It is just such beautiful thing to watch all fans moving in concert and listen to them.5.56 wrote:is it me, or is the A/C now a tad colder?
Great minds think alike! LOL. It's true. I didn't consider that we do have the inline fuse to act as another switch.5.56 wrote: i did the same thing! lol thats so funny. but then i realized, we can just yank the fuse on the fuse holder, and that in itself is the thing to cut power lol
agreed. i also noticed how quickly the fans turn off now, that we have more air flow.kots1 wrote:I can tell that the tranny fan has a secondary effect in helping cool down the main radiator faster.

i also find myself listening for that little fan lolIt is just such beautiful thing to watch all fans moving in concert and listen to them.
i have trailer wiring harness running to the rear, emergency light switch panel controller, the led off-road light, and now this fan. i have everything loomed, fused, relayed, and over protected lol. what you didnt see is that i have the emergency light switch panel wired through not only 2 fuses(one near the battery, and one under the seat) but i also have it through a BUSSMANN Short Stop Circuit Breaker lol(you know, just in case hahah)You got a lot of custom add-ons there coming from the main battery positive terminal. I'm guessing those are for your extra fog/emergency lights. I like the amount of cable wire loom you used and heat shrinking of all joints. If only I am that OCD, then my install would look as professional. LOL.
