I just snagged a CC 1520 motor and I'm wanting to do a dual cooling fan setup on that... is there a consensus on heat-sink and fans combination that works well?
Curious as to what most use.
Thanks!

the only thing I dislike about my fan setup is the need for a external battery..

Do you run the two wires neg/pos? From the fans.
What are those and the covers.

Yep, just Pos and neg. The covers I got here: https://www.ebay.com/itm/1942022599...SgpnzFsTL6&var=&widget_ver=artemis&media=COPY

Awesome set up.
Are these plastic housings and what’s your driving style? BMX track jumping ?

Since the 1520 has cooling fins don't use a heat sink as this will create pockets of air between heat sink and motor. Air is an insulator. Unless you go the extra step and fill all those pockets with thermal paste. But that's a bit of a messy proposition to my mind.
My personal setup is the Powerhobby fan mount which will hold two fans on one clamp and two NMB 40x40x28mm server fans that push 36CFM each. 65°C to 40°C in two minutes flat. Basically the same thing @Rcproponent is running.
@Rcproponent you could just connect your fans to one of your balance leads to nix the extra battery.

^ This is the way.
Adding on a fan mount/heatsink that covers the motor cans cooling fins essentially defeats the purpose of the cooling fins. Those kind of fan mounts/heatsinks are designed for smooth can motors. The can with cooling fins are designed to be the heatsinks themselves. For motor cans with cooling fins, the most reliable solution is blowing air directly across the motor, usually mounting the fan to the can (such as the powerhobby fan mount or similar). Adding a fan shroud to route cooling around the can could also help, but probably only necessary in the most extreme heat circumstances.

I have a very similar fan setup in my Talion that I just put on a Mojave chassis. Where do you like to store your battery at? I'm still trying to find the best solution.

Nicely done.
How do they hold up to big air jumps?

They are all the same basic Rocket/Surpass/unbranded aluminum case fans just with different labeling. I've purchased some from amazon and also from aliexpress. recently got the ones from alipexress for like $7 per fan on a crazy sale. Just took several weeks to arrive.
I run them in my 6s KEXB and one on my tekno mt410 and they have held up well to flips, jumps, and occasional crashes. Still spinning.
Thank you.
So far so good. I've launched it pretty high with some crappy landings and the fans are holding up well. Sometimes the fan mount will rotate/shift around the motor can but that's about it.
You guys continuously give me ideas to play with (edited post)
I went ahead and ordered a few to play with, if they work i'll definitely need some testers!
is there a market for this? (would allow you to run BIG loads off your pack directly with a fixed output voltage)

I like the idea, but to me it just seems like extra clutter inside the car and kind of unnecessary as I can accomplish the same thing off the balance leads of one of my main battery packs with a simple adapter. I know balance leads are only rated for 2A but I run two fans with a combined amp draw of 3.5-4A off of one without issue. I have a 3-way switch located in my right rear wheel well for easy access that allows me to switch between 2S and 3S operation. This is more than enough for my needs as I just don't have any big load items at present and I don't see any coming up in the foreseeable future.
