Senton Anyone use one of these

[Number1Phipps]

When putting the trucks back together we are upgrading both trucks to a 26t pinion gear. To combat any heat issues we thought about running a motor fan. This setup seems a little hokey to me. Anyone use this setup or have any different setups they like? I’m not opposed to changing out the finned can cooler but haven’t seen much in the way for the 3s blx motor.

That will work fine. I generally use the 30mm fans on mine. I fit two of the 30mm on my Typhon heatsink. Just be aware that on 26T you’re gonna cog some. Try to limit your back to back WOT runs too.

I haven't used this, so no idea how good it is.
I just screwed two 30mm high speed cooling fans directly onto the heatsink.

How did you manage that because mine have no provisions to screw into?

How bad is the cogging going to be? Are you suggesting keeping the full throttle runs to a minimum because of heat or another issue?

Mine neither. Just screw them in like I did in the picture, that works and holds up, believe me. (When I still had the stock engine I've been to the skate park with the fans attached. One of the fans literally just broke of inside the housing, but they were still both attached snug to the heatsink [Well, one fan and one fan housing xD ] .)

Any recommended SKUs for these?

I don't see the point of that hot racing gimmik fan

I think that mount is just there to make the larger fan fit? Maybe it would be more funtional if the fan housing was also aluminum, then both the mount and the fan itself would function as additional heat sink surface area.

Yeah but doesn't mean the fan is bigger it is better you need to take in consideration the fan speed
2 small fast fan can beat 1 large fan quite easy

Yeah it all depends on what the CFM rating is overall. Sometimes larger fans are used to get the same amount of cooling as smaller fans so you get the same cooling but quieter fan. I wonder what that HR fan is rated for. It's weird power plug would suggest it might be higher voltage rating since it has an adapter for direct from battery power rather than from the receiver.

I thought that plug just looked cheap and an after thought.

You may need to squeeze the fins together where the screws go in. Use needle nose pliers and just don't go all Gorilla on it!

I thought I saw somewhere that someone used the can cooler from a 4s

The cogging is annoying but harmless. And yes you will heat up that ESC and motor doing full throttle pulls on 26T. You can probably do one or two back to back before you hit 180F

Yeah I’m definitely trying to avoid that kinda temp

The 4s and 3s use the same heat sink, it's the just the 4s has this fan on top https://www.amainhobbies.com/arrma-...XKRz9_tqdJhKiK3pYDFR_3e3pJwhl0qAaAiZxEALw_wcB. I just got the whole setup from Jennys https://jennysrc.com/collections/ar...num-mount-motor-kraton-heatsink-fan-ara102692 (just need the servo ext.)

Rcjuice regularly has these fans on sale https://www.rcjuice.com/hobbystar-turbo-ventilator-esc-motor-fan-30x30mm-gold.html Surpass Hobby has these same fans also. The fans come with a JST connector but will squeeze into an open slot on the receiver or a servo ext.

That connector on the HR fan is a micro deans connector.

AWESOME!! You are full of good info that I wanted to hear. Thank you very much!

I just picked this up cause everywhere else was sold out!

https://www.ebay.com/itm/Evercool-E...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

Looks like it will fit?

Fan Size: 30mm x 30mm x 10mm
Rated Voltage: 12 Volts
Bearing Type: Ball
RPM: 8000 RPM
Air Flow: 3.7 CFM
Noise Level: <22dBA
Power Connector: 3 pin + 4 Pin Molex

I'll rig something to run of my BEC which is set at 7.4

That’s a 12VDC fan and it will be pretty slow even on 7.4v.

WOW. RPM @ 8.4V: 22,000 - 24,000

They don't list the CFM tho. Honestly I'm not sure it matters that much? Hard to tell without real tests.

This is making me want to convert my Senton S3 to Futaba so I can have an external temp sensor on the motor.

Should be 5000RPM. I'll report back when I get it.

I REALLY wanted a ball bearing + brushless fan.
