MMM V3 fan
 

I just put it in my Rustler and I notice the fan does not come on at start up anymore...... I ran it a total of about 3 times and everytime I watched for it as it is suppose to start up momentarily. It always did and now nothing... Any ideas?

Dead fan. Happens quite frequently. Every one of my MMM fans has died within a few runs. Pretty much useless. Thye used to send me replacements. Now they want you to buy a Fan and Case replacement or send the whole thing in to have it replaced. I just quit bothering replaceing them. Havent had an issues at all. You shouldnt either, Especially if you are running it in a rustler. Probably wouldnt ever need the fan. The MMM is like killing a fly with a sledgehammer in the Rustler.

The thing that bothers me is it is not right. For the money I paid for it and as new as it is to not work kind of pisses me off. I do not want to be without it for a month either to get it fixed.... Will they send me a new fan that I can install? If what is all involved in putting a new one on?

Call them. See what they say. Changing the fan is no big deal if you have one. Just carfully poping the case open and unpluging the fan from the board and plugging in a new one. But the new one probably wont last any longer. :neutral:

Just make sure you haven't gotten anything lodged in there; my V1's fan stopped spinning the other day and I couldn't see anything in there, but tipped the truck upside down and shook it a bit...and it started up. I've had about 10 runs on mine and have really beat on it, and the fan's still going strong.

Yeah there is nothing in it. I not even off road with it. It seems as if it tries to turn once in a while then nothing.

where do you get the fans ?

From castle- contact them. You will probably have to buy a new case and fan, or you might get lucky and they send you a fan as a one-off thing. A more durable fan (25x25mm) would be better- there are several threads on the subject if you search older threads in this section...

I think the warmest my ESC got with hard 30 minute run time was 78 degrees. Granted it is about 40 here outside too though. I have sent Castle a email and will see what they say. Being that it is new I would hope they would just send me out a fan. If that one pukes too down the road I will just deal with it.

i replace all my mmm fans with these

Both of my MMMs fan died after just a few runs, in a dusty track. I am starting to understand why other ESC manufacturers designed their fans outside and can be replaced as easy as a fingersnap.

So does anyone have any input on how to remove the fan? I am not stupid when it comes to stuff like this but a good explanation before doing it is always very helpful. I am still waiting to hear from Castle.

Damn, I was looking at getting a new fan for my V1 pre-ordered MMM which is still going strong, but the pricing is insane. Well $12us for the fan/case is ok, but then the cheapest shipping to Australia is $26us.
Almost $40 for a fan :|. Lets not speculate about the exchange rate making it as expensive as a set of 2 new pre-glued truggy tires/wheels lol.

Anyone know any other fans that can be stuck in there?

No real reason to get an "original fan" from Castle, just go to your local electronic mart and get some 30*30*7mm fans rated at 5V.

I got a reply back from Castle. Sad people take advantage of a company as it sounds and truly ruin it for the rest like me and other good people.

Jeremy,

We are no longer allowed to send parts out. Too many people took advantage of a good thing and ruined it for everyone else. You'd have to send it in to us and we'd put a new one on no charge, and pay shipping back. Or you'd have to buy one of the repair kits here. http://www.castlecreations.com/produ...ment_case.html

I wonder if Mike will be stocking these case/fan combos? Maybe he could get a bunch of just fans to help keep the price lower (besides, I can see more fans going bad than cases). Of course, you could use an aftermarket fan, but the CC fan has the proper connector on it.

I am using the Traxxas bracket that comes on the E Revo. The one thing I think may be a possibility is that the hold down is wrenched down too tight. I was only able to use one side to mount it and then have strong velcro underneath. That was my first thought and then when I loosened it all the way up it did not help. My thought was it may have pinched or crimped it a little due to only tightening one side. The fan did work after manipulating the switch on/off about 3 out of 5 times today when testing it on initial start up.

Yes that would be nice. I sent him back this email.

I understand your stand and that irritates me as well when people take advantage of a company or anything for that matter. The fan works intermittently. Any idea what may be the cause? I am using the Traxxas hold down bracket that is made for it. Would it be possible for you to send me the directions on how to open the case? It may just be a connection and I am confident I will be able to do the work I just would like a little direction.

You can see in this picture what I was referencing in regards to the bracket. I wanted to use it for the switch mount and a extra holding point on the ESC. The ESC is not going anywhere with the one screw and the velcro underneath. I also have two layers of padding underneath the ESC to absorb some shock.

The fan wire is routed from the fan (duh) around the main power PCB to the bottom brains board. Sometimes, the wires can chafe against the main PCB and cause partial breakage. Or could be the connector is not fully inserted. Or could be the fan is simply on its way out (dirty bearings, etc).

When/if you get the "official" directions on how to open the case, post the email and I'll create a new thread and make it a sticky. Most of us have opened the case without incident, but the little tabs are fragile and can snap fairly easily. I know the instructions for doing this has already been posted here somewhere, but I'm too lazy to go looking for it right now. IIRC, it was posted by a CC tech/rep.

I will do that Brian. Dirty bearings is out of the question being this ESC is new and has not been ran off road as of yet. I am hoping it is just that the plug for the fan is not fully seated.

Awesome and thank you!
