MMM fan not acceptable
 

can i cut a hole in the case and bolt a fan to the heat sink so I can change it without taking the whole thing apart? already broke 2 clips. cant do this every 15 minutes.
my mm has the same fan on it for hours of track time.( for your info)

will this void my warentee?

It will void the warranty according to castle. Really sucks too, I have been running a high quality fan (was used to begin with) for nearly a year on one of my MMs (track use too).

ive seen some guys at the track tie it to the side of the esc, and taking the originak out completly, no warranty voiding

cause I have these fans i bought that are called magnetic levatation fans? or something like that. they flow like 6 cfm and run at 9000 rpm at 12 volts. i had a fine design motor that waS running 170 after a few minutes and this fan cooled it to 125. plus they never break.( so far) it would fit perfect on the heat sink if the top of the case was acidentlly removed.:-)

you know another serious option is liquid cooling like boats do. a convection set up with no pump. no moving parts, nothing to break.

sunon also makes a maglev fan that is 30x30x6 which should fit right where the mmm fan is. $25 for one though.

I was thinking something more like this:

Mount it to the chassis over the heatsink so that it didnt damage the esc in a crash...

No, seriously....

the fan definitely is a weak spot. i'm on my 4th one now. =/

And you don't even need a motor. You can propel the truck with the fan:lol:

It looks so cool- imagine having that sticking out the bonnet/hood of an MT, like a giant supercharger you see on hotrods... **dreaming..**

Wow, 4 fans, mine just quit (the fan not the esc). Did you have castle fix them, or did you just replace them yourself?

you just replace it yourself. mine quit last week. call them up and they will send you a new one. very easy to replace also. they will tell you how to do it over the phone.

I just replaced my 3rd fan. This is getting ridiculous! Is there some secret to keeping the fan intact? Is Castle going to change the design?

I ran thru 5 of the CC fans. My case clips are broken from opening and closing so much as well. I cut all of the fins out of the top fan hole and replaced the fan with an Integy 7.4v 30mm fan and its been running for 3 race days now. The stock MMM fan never made it thru 3 qualifiers before it died and I would end up running without a fan by the time it got to the mains.

Yes the CC fan suck. Hopefully they have it fixed allong with the BEB issue for the next release of MMM in a few weeks.

Integy fan not acceptable
 

I've used 2 No!vak 25mm fans at 8+volts for no less than 30 hours, holding up fine. They will blow out a candle across a small room, they sound like little turbines too...

I got 2 of the Integy fans cuz they were cheap, thought it would be a good idea to run them closer to rated voltage. EHH!

Even running at 8.4 (their max rating) they move like NO air, and they stink like a fried pcb, the little motors are HOT, I'm wondering if they're already over rated at 7.2.

Anyway most of you probably know all these things are re-branded. You'll almost always see there is one sticker on top of another, peel the top one off and you'll see the Novaks are Young Lin brand, and the Integys are TOPCAD, with an address, topcad.com.hk- FWIW.

Run the Novak 25s at 7-8 volts and they work incredibly well.

BTW I tried the Integy 7.2's at 12 volts and they STILL didn't move the air like the Novaks on 8V.
