Throw these bad boys on there and rotate them to the outside, facing the sideguards. The actual fans should almost be touching the sideguards of the truck. It'll be a tight squeeze, but it'll all fit once slightly rotated.Anyone know of a good way to get a fan mounted in here? Not a lot of room to work with, the motor sits on the chassis and almost touches the center drive shaft. View attachment 362986
Awesome thanks man, thanks for posting pictures too, helps me visualize what will workI have had experience with those clamp on heat sink units.
1. They get loose over time
2. Doesn't cool well, because the heat transfer from the motor to the heatsink is not great.
I ended up with motor clamps that hold a fan.
I had this in the past.

And I run this now:

50mm fan om a 36mm motor.
This would be great for your setup and I think it will fit

I have a picture of it a mounted on one of my 6S rigs in my phone, but that won't do you much good. When I get home I'll take a picture of the dual fans on my 3S rig for you.Awesome thanks man, thanks for posting pictures too, helps me visualize what will work
Do you have a picture of this mounted?
I'm willing to bet one of the biggest difference makers in your setup are the fans. I've tried that large Hobbywing fan you have and it absolutely sucks compared to the Rocket fan you switched to. Those Rocket/Surpass fans move way more air.I have had experience with those clamp on heat sink units.

Yes, the Rocket fans are awesome, but you need to keep it in place, this heatsink clamp from Hobbywing is a piece of garbage.I have a picture of it a mounted on one of my 6S rigs in my phone, but that won't do you much good. When I get home I'll take a picture of the dual fans on my 3S rig for you.

Oops.. I guess I didn't "look".. LOL, I posted the exact same mount. Sorry.I use this one in my MT410. It works great in tight spaces and holds up well.

Thanks man, appreciate it@6mm Lapua I know you already ordered a mount, but im a man of my word, so here's the picture lol. This is my setup on a 2450kv motor in my Big Rock. Can is 3674, thought it was bigger than that.

Oh she got pretty toasty, I was hoping to not need a fan but it got hotI don't run a fan on a 4268/2600kV Quicrun in a 12lb aluminum Mojave on 4S, never gets much over 100 degrees at the track on the 8BL150G2 esc even on 6S.
I'd mount it to the chassis if you absolutely had to have the noise.

Might be under geared if you're not literally holding it wide open the entire bash in tall grass. Or you have binding in the drivetrain...Oh she got pretty toasty, I was hoping to not need a fan but it got hot
How hot is hot? I mean, are we talking to the touch? Or with a temp gun? 120-130F is hot to the touch for most, but really nothing for an electric motor. I don't get concerned until around 160F, but even still I have seen readings over 200F on some of my motors.. not advisable, but they still run.Oh she got pretty toasty, I was hoping to not need a fan but it got hot
Good point, it might be worth checking the mesh. I thought my new motor was getting hotter than I expected so I loosened the mesh a tiny bit and it’s helped keep it cooler.How hot is hot?

I’m running a 16t right now and love the way it runs with it, I don’t think 17t would be a good idea with trying to keep temps down, I guess I could try after the fan gets mounted.Good point, it might be worth checking the mesh.

Also if you was to run a bigger pinion you will get a bit more drive shaft clearance.
