Wow, what a collossal waste of money but not judging!

Do a little research and buy these fans for $15ea on digikey or anywhere else.
You will need to be able to do some very simple soldering, but at 8x$50 it might be worth learning.

FYI, they way they are mounted by default wastes roughly 60% of what they could do and you can get away with 1 mounted correctly on the motor.
Make sure you have roughly 0.5-3/4 inch gap between any surface and fan exhaust. Otherwise, the fan is fighting itself. Hence, many mount 2 as they do not understand aerodynamics.

Last advice, these will not hold up to bashing i.e. jumping etc, they will break. Ok for speedruns but almost everyone moved to 'no fans' and add them for cool down only, after the run.

You are correct, you will need to have a facebook account for purchase.

I just ordered a bunch of these. They sound like jet engines and move a ton of air. They need a bit of wiring done but work well on my K8s

You are doing the right thing!
If you want better than Gamechanger these are the ticket, again not for bashing.
You can always look up the part number in China and see if you get a better deal.

Yeah their not really meant for bashing but I figure they're so cheap they're disposable.

I bought 5 to start and am still on the first two. Mind you I don't really get to release the K8s very often.

If you go DIY, I recommend these: https://www.mouser.com/ProductDetail/108-THA0412BN

Not the highest output but the aluminum housing holds up WAY better than plastic for bashing. You will also need some shrink wrap and a connector. Really I don't think the price of Game Changer fans are insane after you consider the little extras and labor. If you're handy you can definitely save some money. Also a good skill to build in this hobby.

You should try do DIY it, save a ton of money. This is what I came up with when I didn't want to cough up a ton of $$$ on fans.

Llolol. 34 week lead time. No thanks
D..I..Y.. more personal satisfaction.

I had contra-rotating fans at one point. Each fan had 2 in them, spinning opposite directions.

Stock:​

522 Can Ship Immediately

I guess if you need more than 522 of them you'll have to wait 32 weeks...

I thought it was funny since those lead times are real-life in my world. Insulation is insanity right now.

Keep in mind that you can pick any 12V DC fan with comparable cfm, the way they are mounted above is wasting about 30-40% of actual air flow due to back pressure. You can easily pick any fan 20 CFM or higher and you have a great solution that surpasses any gamechanger setup. They are in the 25CFM range if I recall correctly.

newark, digikey or mouser all have stock. If in doubt feel free to ask, yes you will have to do some soldering or buy yourself some adapters. Spending $50 per fan ....well it's your money.

Digikey stock today for alu framed, filtered out the other 20+ plastic versions.

PM for a link to powerful fans for cheap. I get them from one person on eBay. Prices are unmatched and he does what ever color tops and wire sleeves.

I have a 40mm and just got a 50mm for my K8 motor heat sink. Run off 3s/4s. No joke

How do you suggest mounting them with an offset from the motor to avoid backflow? P are suggesting not to bash with these but that's when I need them. Running 1650kv and haven't really geared it very high but it gets hot where I live. Lower kv? Preferably do t want to run a fan at all?

 

[jkflow]

You can use dual standard 30mm fans that do not have the mass.
Motor mounts are available, just avoid the heatsink altogether. For those you need standoffs.

My preferred style:
