CC Blower now on sale!

[RC-Monster Mike]

This is different than the "cast" parts, but similar in the fact that you need to make the mold before you can make the part. The parts are quite inexpensive to make AFTER you make the casting. Those extruded aluminum heatsinks are cheap enough AFTER you buy the extrusion head(couple thousand $$), but they are useful only for the motor size/diameter they are intended for. The Castle blower is universal in its fitment - "Fits on motors with outside diameters between 1 1/2" and 1 7/8". This universal utility would not be possible with aluminum(and pretty much "rules it out" for this particular item). I don't think any description of the item eludes to aluminum construction in any way - not sure how anyone would be "expecting" it based on the product description. :)

that castle fan is not a blower, its a YiMeng 7-bladed axial dc fan rated 3.4 CFM deduct some, for that slick shroud with a sticker on top obstructing the airflow

It could be replaced with a sunon maglev 4.9CFM, 30x6mm fan (cheaper than the whole fan shroud with fan): http://www.sunon.com.tw/products/pdf/DCFAN/GM3006.pdf
its half as noisy and more efficient
12 bucks here: http://www.futureelectronics.com/en/...GNSUNON3579810
comparison of the two fans (pressure chart double checked)


i use this on mamba max 3-5S with 35V power cap

Sunon KDE1235PFB2-8, 35x10mm 5-13.8V, 0.8W, 6000RPM, 5.2CFM, 0.06A, 19.5dBA, 5 blades and this for 1900kv motor

Top Motor, DF127015PH 70mm x 15mm, 38,9CFM, 4,1W, 3-Pin CPU fan, 4300RPM, 0,34A1 12V, 37,5dBA, 11 blades

both 12v rated fans

"Designed in Kansas - made in China" Bah, sounds so Hollywood. Hobbywing at least use 50mm fans. A 30x6mm fan on a 2-3000+ watts motor is ridiculous. Overall efficiency is better with fans, good ones and big ones.

Pull a fan from your notebook or PC and see what happens to 'overall efficiency'

Umm, "Blower" is the name of the product. Like "MMM" or "Sidewinder".

Yes, we know there are better fans available. No, I wouldn't pay twice as much for it because it had a better performing fan. Why? Because that expensive fan would still get eaten by sand/sticks etc. and would have to be replaced.

Oh, to the people complaining about it not being made from Aluminum- It isn't a heatsink. It's a shrouded fan. The CC motors already have a heatsink built into them. The Blower is meant to force air around the motor through the heatsink fins for better cooling. Making something like this out of Aluminum would be a waste of said Aluminum as there is not enough contact with the motor case to do any good. If you want some "bling" buy some chrome spray paint.

good idea with the chrome spray..or green spray

I wasnt addressing you/we in particular, that probably are down with stuf . We also know that sidewinder and mamba are not snakes nor serpents. I was pointing out for those that dont know the part what it is, despite what it looks like ( a blower or a micro-V8 or..). And what better fan to get if say, the fan would RIP one day, or just want a better fan.

that 'fan grill' in short ruins the airflow and also makes the fan prone for carnage, as debris would have a hard time reflecting/escaping again. I recall a certain 'pinball beating' a fan got, a simple grill did that, costed some led lights, anyway..

It may be more matter of preference than whats 'best', using a fan grill, filter, or none. in a grill twigs could stall the fan and while it may not break the blades, render it useless anyway. If people want to buy fans or not: There are better fans and what one intend to pay, is sort of preference as well..

suicideneil> YOU! thanks for good help on BYT dude. i hear you on that fan-hate hehe. Overclockers might not agree, replace a MMM fan with a sunon and you get 10 degree lower temps, translate that into power. That Castle made the fan trigger instead of running all the time, could that be a way to extend fan life, far out translation ? lol. it saves the batteries/bec but thats about all. Some people bash in -10-15 celsius, others in +33 celsius all year long, Im inbetween with cold winters and hot summers, still i like to use fans, i believe it helps any efficiency there would be to gain.

it can be a neverending argue, but we're not all 'supposed to agree' anyway!
for the record, "I agree, but = I don't agree, but".

what is 'overheat' - one can blame the motor, the esc, the lipos...if you can keep things cool and gain performance, whether a truck is 'too heavy' 'too much geared' or whatever, cooling is a helping hand that dont mind the method of torment, its like red cross in a war

maybe its good to say this, there a thing to it: fan cooling it not a way to 'lower the temps' as such, meaning lower temps can be achieved in some setup, regardless of whatever fan cooling is present. but at any right/best gearing/setup (all in all) its still a beneficial method to get better efficiency/performance/runtime. So in a way fans could be left out when trying to find a best setup, and after that, plug in the fans
