is it bad for the fan to run?

[josh9mille]

just upgraded to 5s and noticed my fan comes on a lot more often (duh right?) It came on when i used to run 4s at least once per set of batteries, now on 5s it comes on very frequently. Is that bad? Im running a completely stock savage flux (tires, wheels, gearing etc...) Just wondering if this is normal, or is there something i should be worrying about? It has run flawlessly since i bought it, no issues at all. Just a little concerned is all. Thanks!

Well, if it's turning on and off multiple times per run then that means you are hovering right around the 150F point, which I wouldn't be too concerned about. But if it is coming on early in the run and staying on until the end you might be pushing the temps a bit. You don't want to rely on the fan, you want it to be setup so if the fan failed your ESC would get hot, but not enough to thermal.

You probably should gear down so you are geared for the same speed with 5s as you were when using 4s. This will help reduce your temps.
