MMM fan not acceptable - Page 2 - RC-Monster Forums

I am still on my 1st CC fan (no mods done to it at all) after 3 hours of use (track use) It's going great.

I tried the Novak 30mm in the MMM. It lasted 1 1/2 days in the MMM. Better than stock, but still not quite durable IMO. I personally dont really care if the fan is moving air or not. As long as it preserves the warantee. The MM doesnt overheat in a 20 minute main with no fan running. As long as there is a fan running on it if the MMM dies its still under warantee and the fewer times I have to open the case the better IMO.

How did you have the Novak fan wired in?

plugged into the Rx

I don't get it - I've been beating the crap outta two MMMs and haven't had a single fan problem (or other problems for that matter, luckily).

No fan issues here either- stuffed mine full off grass, landed on my lid several times, and popped the esc case open 3 or 4 times too; fans still runs fine.

I got lucky...

I have 3 30mm fans on order from Tower I am planning on using zipties to secure the fan to the top of the MMM if anybody has a better method chime in.......

is the novak 25mm a direct drop in? how do you guys have it plugged in...did you guys just take the plug from the ccfan and solder it onto the novak? i have never installed a fan besides the cc one. can you explain the wiring or pics would be great. the novak upgrades definitely sounds like something i wanna do, but i just dont wanna short anythi8ng out in the process. and how do you guys have the option to choose whether or not to use 7 or 8 volts??

The novak fan is a drop in replacment (except the wiring) but it will hit the fan cover & break as well. I found 4 small washers that fit inside the novak fan mounting holes. I put 1 in each hole (on the fans topside). Then put the fan inside the MMM fan cover. The washers space the fan father away from the cover keeping the blades from catching on the fan cover slots. As for the wire, I used the connector & wire that comes on the fan. Just run the wires out the side of the fan cover & plug into the RX in an unused slot.

blueb8llz · 06.30.2008, 05:21 PM

ahhh thanks for the washer tip. but i didnt know all i had to do was plug it into my reciever slot? i always hear of people slicing their wires and running it though...?? thats where i always get confused. if i knew i can just plug it into my reciever..thats not hard at all haha. so how do i make it to 8 volts? how did you wire the fan wires out of the mmm casing?

RBMike · 06.30.2008, 05:50 PM

There are plenty of places to poke the Novak fans connector/wire thru the MMM top cover, you don't need to cut or drill any thing. You cannot make it 8 volts if you do it the way I did it. Some guys are using the balance plug on the battery to get higher voltage but I don't like to intentionally un-balance my batteries.

You may need to buy a extension as the wire on the novak fan isn't very long. When you take the case off you will be able to work out how to mount the wire out the case to the RX. If you don't have a extra slot you could also look at a y-harness.

I have no exp with the MMM, had 2 on order but cancelled when all the trouble started brewing. I run 2S+2S so it's as simple as running the fan off one pack, if you're using 3S and up then it's not so easy. The Novak 25's do push pretty good air at 5 or 6V, if you're running an adjustable bec then set it at 6V. I was actually using my two 25's for pack cooling back when I was running Nimhs, at over 3 inches away, which is why I needed the boost. No more of that nonsense, lipos don't need it. So I'd say 5 or 6V is fine if it's right on top of the ESC... as for mounting, can't help ya there.

blueb8llz · 06.30.2008, 06:46 PM

ok sounds easy enough. im using a 2 channel reciever and the only available slot is a b/dsc? will that work? can anyone verify that i will or will not need a extension for the novak fan to the reciever. if any of you guys have a 3905 emaxx with the novak fan, i have the reciever and esc are their factory places. it looks like the novak fan wire has to be about 9-10 inches to reach my reciever.

The Novak 25mm is not a direct drop in. The Novak 30mm fan is a direct drop in.

It comes with a plug that will plug right into the Rx. Just plug it into an open slot on the Rx and it will power the fan. I just ran the fan wores out of the MMM through a cooling slot. Simple.
