New fans arrived

[Johnnytoofast]

Alright everyone.
So someone on here recommend this sight for pretty cheap fans. They just got here but I'm not an electonically inclined, no. Idea how to wire them. They both have four wires b,y,r,b. I have an old 3s pk that I wanna use. Is that possible?
Thanks in advance.

Red and blk all you need

 

[Johnnytoofast]

That's all I do? Well wtf. Thanks man.
Do you know if it's possible to run them on 3s?

Solder a connector for receiver or a balance plug adapter

they be the ones i use , red and black as said , i run mine from a 3s lipo , did use a bec but it bust .they move a lot of air for the price

You can go ahead and cut off the 2 other wires right at the fan. Servers use them to measure and control fan speed. With no signal on them the fan will just run at full speed.

Thanks guys. You rock

I have a few of these (different brands) they work great and move air, but they sound terrifying....

What site you get them from

 

[ChemEng]

I have pulled a few off of an actual server... but recently another forum member turned me on to these:

https://www.ebay.com/itm/Sanyo-Denk...2349624.m46890.l49286&mkrid=711-127632-2357-0

Seem like good quality, but at 25k rpm they sound like a dremmel.

Red-positive, black - negative.
They are 12V fans, yes they will run just fine on 3S.

I got this one off ebay for $6 .83amps and its pretty quiet but moves alot of air. Dropped 30 degrees off esc

How do these hold up to bashing?

They are half the amps and less than half the speed of the one I posted... not a bad thing, the reduced noise is a bonus and I bet they still move enough air.

 

[TriggerHappy]

So far i havnt had any issues i do have a guard on it. Iv got it mounted on my max6. Running on 7.2v. Keeping my eye out for two more for the motor.
@Edough13 and @jondilly1974 have the fans you posted. Edough has a vid on one of them hovering over a table. @ChemEng

You can also use the SanAce 36, direct bolt on and no mechanical adapter needed.
They will not hold up well to jumping and odd landings or weird impacts. None of the 12V fans will, they have too much mass in the fan blade and they will break. Typically an issue if you land upside down etc.

On the Max6, I found that mounting them too close results in overheat. That large middle area is blocking airflow across the center of the ESC, just a big void.
Get some standoffs if you see that happen. Eliminates that issue.

They work great, until they break

My mmx8s stock fan only lasted a few batteries and it was super light.

I just think bashing with all the impacts, dirt, grass, sticks and sometimes even water is a really tough application for these little fans in general.

I have a feeling that my quest for the holey grail of cooling fans will be lifelong.

I think if you make some stand offs ( nitro fuel line) and put them between the fan and what you mount them too might give it like shock absorber type mount. It should take some of that impact. Not entirely sure as I'm using them for a limitless and not a basher but wouldn't hurt to try. I only paid 5 bucks a piece.

 

[jkflow]

They will work fine on a limitless. I went back to 35mm alu fans for my bashers. ESC overheats during summertime and it's no fun, that is my 'seasonal break'.
