I bought the same brand, only mine is 16". $36 on Amazon. I found the same thing about the amps. Startup was about 10+ amps, runs about 6 or 7... Great video. I put mine on my very large lawn tractor. (Steiner 450)
Got a 👍 from me & subbed, the mesh wire as a mount is a EXCELLENT idea not only for a safety issue but also because such is WONDERFUL as a mount because you have so many options to mount it and other stuff because of the availability of holes that you DON'T have to drill, I want to do the same on a smaller scale to put in front of my Hot Florida driven Air cooled Honda 300 , so if you don't mind I may like to connect more directly with you about my project, I'm a electrical idiot, thanks for your production
Bigger fan works better than dual fans IMO. Get the biggest you can fit either way. A roof scoop or gap like I have is key to airflow. You must pull air from top to get good flow.
I tried doing the same thing. However I have a metal roof that sets closer to the roll cage and won’t allow the fan to pull enough air to work properly. I’ve tried several ways of mounting it to create more air space but wasn’t able to come up with anything that would allow the fan to blow enough air to make it worthwhile. Glad to see yours is working though. 👍🏼
The video does talk about how I physically ran the wiring from fan to battery. It does not cover the exact wire to terminal connections, but each speed controller may be different. The most important thing is to have a fuse and locate it at the battery. Next make sure the switch can handle the max amp draw the fan can make. The wiring will go from battery to switch to speed controller to fan. I chose a lighted switch so I know that power is cut off whenever the switch is off. Leaving the switch on with the speed controller on lowest setting can draw power but not necessarily turn the fan… so you could inadvertently run battery dead over nite. Good luck with the project.
Fan depends on your space availability. I used a 14in fan, which is available at auto parts store or online. I got curved blades as I think they are quieter. The main component is the speed control which I got online. If you go to 4:51 in video it has a good picture of it. I mention the key specs you will want (PWM, 20khz and 20 amp). These controllers are available at many online stores.
Great Video, I built my fan unit based on your design and it came out great. Only problem I had was finding a PWM unit that would work, tried several units from Amazon and they all failed to control fan speed. can you provide link to the unit you used?
I just recently purchased a fan for the roof of my golf cart. 12v 120watts. I purchased a PWM off of Amazon with a kill switch built in. When I hook it up and turn it on and turn the dial up it will not turn my fan at all. I hooked up my multimeter on the outlet side and it is pushing 12v out of the PWM. Fan will run straight to power just fine or with a two way switch. Any thoughts on what I am missing?
The video shows a detailed picture of the speed controller and the hertz rating I recommend. You can find that brand many places online... they are cheap. The rest is just a switch and radiator fan that fits the size you need. The biggest fan you can fit the better so you can run at slower speed and move more air.
I'm installing a similar system but the speed controller comes with a very small on/off switch wired in with extremely light gauge wire. I want to install a better rocker switch in the dash but keep the controller mounted to the roof. Can I bypass this switch altogether and tie it into the power source or do I need to use the same light gauge wire from the existing switch wire?
Probably either will work. I would turn the small included switch on and use a separate power switch. That way you know you cut power to the speed controller and fan when you turn it off. Will prevent a parasitic draw.
So question I’d like to ask? What are your thoughts on a fan of similar size under the dash? I’m looking for dust control mostly, would that cause the pressure around the feet area to keep the dust out? Maybe not quite as harsh as the fan blowing or noise right at your face ??? What you think?
Would be terrible for heat. Most of the heat comes from under the dash area because that’s where the radiator blow it.., and the hoses run under the floor. Plus, where does it get the fresh air? You would just be blowing dust and heat around. You MUST get fresh air from above the fan if you want it to work properly. Make sure to get the LARGEST fan you can fit, so you can run it slower rpm and the noise it not bad.
How did you run the plug from the fan? Like I see the blue/black coming out of the did you use a white plug like what’s on the end to connect or did you cut and hardwire?
At 9:25 - When you say you fused it to the battery can you elaborate on that. What size fuse did you use? Was the fuse part of the wire or did you add it?
You should add a fuse on the wire very close to the battery. The wire should be sized to handle the amp draw of the fan and should also be based on the length of the wire. You can lookup wire size charts online. The fuse should then be sized smaller than the wire rating, so the fuse blows before the wire fails. Remember, fuses are there to protect the wiring.
Notice that my setup pulls air from a gap between the windshield and roof. This is KEY to getting good airflow and cooler air. Too many people miss this and expect bolting a fan to their roof will work well… and it does not. Add a hood scoop on the roof or do a setup like mine. You NEED fresh air coming in, not just recirculating the cab air.
I would guess it’s around 120w since it was pulling 8 amps. Remember the air flow is more about pulling in air from ABOVE fan. If you don’t have that you may be disappointed in performance. I have a gap between roof and front rollbar that let’s air in .
Ambient air, which is MUCH cooler than the hot air that builds up on the interior from the engine. The fan helps remove that hot air. It’s not as good as AC, but it’s a huge improvement. Try driving your car in summer with no AC and windows up, then roll windows down… you will see the difference.
@@arthemmingson2439 I showed a close up of the PMW controller. There are many on EBAY matching the specs I mentioned. Vendors come and go, so a link would already be gone. As far as a fan, measure the space you have and get the largest that fit in that space as it will move more air than a smaller fan.
I have same speed controller, 20a switch and 14" fan as yours. Do you think the switch and controller will run dual 14" fans or would i need two complete setups?
I would do individual setups for many reasons. I would also be concerned that your battery and stator could handle 2 fans running at same time. That’s a lot of amps.
Hello sir...I hooked up a 16 inch fan using control switch like yours...motor simply goes on and off when hooking up speed control..Little dial does nothing...Any ideas? Fan looks identical to yours but is a 16 inch car radiator fan...Control switch looks identical to yours..Not sure why I can`t slow fan down..3rd switch I try..
Double check your wiring. Possible fan draws too much current or is wrong type of motor to handle the PWM controller. I would try a different fan to make sure controller is working ok.
@@swalesutube Turns out I had all grounds going to ground bus thinking that was acceptable..Saw pic of switch wiring..None went to ground bus..Working now.Thanks for replying.Fan is great
Do you have a gap above fans? Mine has a gap between top of windshield and roof so air is drawn in from above fan. You can add a roof scoop as an alternative. Also bigger fan is WAY better than 2 smaller fans. Moves more air at less rpm.
@@swalesutube there are 2 fans because it's a four seater, 1 front, 1 back. There is a 1 1/2" space above the panel that holds them and there seems like more air is pushed out the gap than out the fan.. It's also in a closed cab but when I tried it on the bench, the results were the same.
@@swalesutube curved blades, switch has forward and reverse. Reverse pulls more but circulates the air more. When in forward, all the air is pushed out on the outer portion of the fan but it is not very much.
They change all the time. That’s why I show the specs of the PWM controller. The fan was from auto parts store, you can use any fan that fits, but the larger the better.
@@swalesutube I looked a few of them up. The seem to be generic. Have you ever had any issues with the PWM or with it being non waterproof? where did you mount it?
The video explain you want to choose the PWM without holes in the case, it help keep dust out and better water resistance. I mounted it above the framework, right next to switch. I would have to sink RZR to the roof to get it wet.
@@swalesutube Yea I saw the video, I just wasnt too sure about how it would handle moisture. Looks sweet tho. Thankyou for your help. How have you liked it so far?
I have the same fan does anyone know why mine blows the wrong way instead of blowing air out it sucks air in and no matter how I wire it it won’t blow air out only suck air in

Thank you for sharing! I’m looking into running a duel setup in my Pioneer 1K to cools us down on out hunting trips!
I have a pioneer 1000-5 wanting to do a duel set up also. Have you done yours yet would love to see some pictures

Pretty professional install, thanks for the great idea!
Very nice idea. Looks like it will work out well. I want to try something similar for my can am commander . It’s really hot in the cab.
I wouldn’t be without it, makes a HUGE difference.

Make a hood scoop.
I found the same issue and am mounting them behind the driver's head between the particle separator and the roll cage... that worked well...
This video blows!! Cool air! Thank you for the ideas!
Thanks man!! I'm going with 2 14inchers in my mule pro fxt!!
That thing will probably hover with 2👍
I wish you showed how you did the wiring. I ordered the exact parts you used about a year ago. I am finally about to install

What are your thoughts on a dual battery set up with isolator? Thank you for any input!
Thanks, I’m planning on doing it on mine
Any way for you to post a parts list of your video kind sir? The ole lady get steamy...

Sorry, don’t have a link. The video shows a picture of it. Check EBay. Possibly your fan is not compatible with PWM. I got my fan at AutoZone.
Thank you so much❣️❣️❣️

What’s the wiring that you used from the fan to your battery? Also, suggestions on where to purchase the wire. Thank you.
Got it at local hardware store. Best to lookup wire size based on fan amps and distance from battery.
You should sell these.
Can you post a parts list and links?

Let them kids learn! Lol 😂 no touchy
So after 3 years how has it performed?
Best upgrade I have ever made! It keeps the cab cool and helps keep the dust out.
Has the fan in the controller held up or have you had to replace them?
Both have been fine. The only issue I had was the on/off switch needed to be replaced. I think dust got in there. So I replaced with a sealed switch.
So question I’d like to ask? What are your thoughts on a fan of similar size under the dash? I’m looking for dust control mostly, would that cause the pressure around the feet area to keep the dust out? Maybe not quite as harsh as the fan blowing or noise right at your face ??? What you think?

What kind/brand of electric fan is that? I would like to get the same. It looks slim and well built.
I don’t remember the brand, but it came from AutoZone.
thanks guy!
How did you run the plug from the fan? Like I see the blue/black coming out of the did you use a white plug like what’s on the end to connect or did you cut and hardwire?
Cut and put new connectors on to wire to speed control/switch. Wires go from there to battery with a fuse just before the battery.
At 9:25 - When you say you fused it to the battery can you elaborate on that. What size fuse did you use? Was the fuse part of the wire or did you add it?
You should add a fuse on the wire very close to the battery. The wire should be sized to handle the amp draw of the fan and should also be based on the length of the wire. You can lookup wire size charts online. The fuse should then be sized smaller than the wire rating, so the fuse blows before the wire fails. Remember, fuses are there to protect the wiring.
Do you get the heat from the black roof in the summer time? I would imagine the fan pulls that heat and transfers it to you
Notice that my setup pulls air from a gap between the windshield and roof. This is KEY to getting good airflow and cooler air. Too many people miss this and expect bolting a fan to their roof will work well… and it does not. Add a hood scoop on the roof or do a setup like mine. You NEED fresh air coming in, not just recirculating the cab air.
Did you run a 120w or 80w fan
I would guess it’s around 120w since it was pulling 8 amps. Remember the air flow is more about pulling in air from ABOVE fan. If you don’t have that you may be disappointed in performance. I have a gap between roof and front rollbar that let’s air in .
Is that fan a pusher or puller?
Can be wired either way. I have mine pushing.
How does it do for dust control?
It helps a ton. The positive pressure keeps a lot of the dust out.
Doesn’t it just blow warm air on a hot sunny day with that black roof?
It pulls air from front gap between roof and windshield. So it’s same temp as outside air. Makes a huge difference to keep you cool and the dust out.
Yes hot air
Ambient air, which is MUCH cooler than the hot air that builds up on the interior from the engine. The fan helps remove that hot air. It’s not as good as AC, but it’s a huge improvement. Try driving your car in summer with no AC and windows up, then roll windows down… you will see the difference.

Its wired backwards. they are push pull fans depending on the way you wire it.
Can you flip the fan over? You might need longer bolts, or make a bracket.
Any way you can post a link for speed controller
Lots of them on EBay. Look for the specs I mention in the video. Should find one around $25 or so.
Just dumb, if you need a fan you may be ridin in too hot of weather. There's cooler seasons like winter, fall and spring. Summer is for boating. 😂.
It works on boats too!
Heads up. These pmw are trash amnd burn up. Read reviews before ordering one
I just recently purchased a fan for the roof of my golf cart. 12v 120watts. I purchased a PWM off of Amazon with a kill switch built in.

Possibly the PMW cannot deliver the amps needed to start the fan.
