How would I know if the fan is not working anymore? Or should I say, what if the fan fails to come on at 140*F and fries or thermals the MMM? Any built-in safety feature?

Good question I was wondering that myself.

most of us won't be able to get the monster max to the point of thermalling. I run a 1.5d on 4s in a buggy and when the original fan failed the esc only got too 175 degrees. That was on a track in race type conditions in low 80's heat and a fifteen minute run. If your running a tamer motor or a slipper in a truck or truggy you may not need a fan at all.

wow i asked for a thermostat on the fan.:-) this way the fan will llast so much longer.....
so when should i order another mmm and send in my working perfect mmm for an updated one?

I don't know why cc make this case for the mmm :surprised:

why they don't use case like this:

Can't see the pics g8-maxx

DRIFT_BUGGY sorry now you can see :)

not sure of the venom, but cc would have to lower their quality standards to make the ecs fit the other cases!

Like you said, . What about the rest that can thermal the ESC? There is always the possibility and a newbie might take faiulre of the fan as an indication that the ESC is still cool even though it's not.

I don't have any problems (knock on wood) yet on my V1 on 1515 1Y on 6S. However, I will be exchanging it for the V2 once the backlog is over.

BrianG did some mods to his fan and plans to not run a fan...curious as to how he makes out. I took my fan off of the esc and wired it to the rx and I am running an external bec so, we shall see what happens. I would be curious w/the v2 how temps would be w/out a fan on 4s then 5s

George, Are you infact in that situation? If your running that setup in a truck or truggy and geared to race and not too the moon or in an above average climate, probably not. I've been one of the fortunate ones with a v1 monster. Hooked up my fan to my rx almost from day one. I've run overgeared just to see what could happen. this esc is pretty darn tough IMO:mdr:

I'm using s trobe slipper with 51T spur and 20T pinion. My diffs are 1/8 scale 8 spyders with 3.3:1 ratio.

Can't tell if I'm going to thermal it but the possibility is always there.

with the slipper,unless you really overgear, your safe.

BrianG (i think it was) modded his body on his V1 MMM like this

Yup, that's mine all right. Since then, I added the UBEC mod:
