Default HOT ESC

Ok i'm having an ESC problem i think, I bought some venom-racing 5000mah NiMH battery packs, since i'm having longer/harder run times, my ESC is heating up BAD. I have to let it cool down which is no big deal, but after that about 5 mins later its shutting down again, now do they make some kinda of fan or something to put over top of the heatsinks..? or should i just buy a new ESC, cause i been looking at the Novak XRS, as an upgrade. What do you guys think i should do here, any help, or links would be greatly appreicated.

FYI: the ESC is a Hawk reversible from Nosram, also it's for a 17turn motor.

Thanks guys/gals

Yup, you can mount a small 6volt fan over or blowing across your ESC
Upgrading to a better ESC won't help because you are really working that ESC with that much run time.

possible facts:

How many turns do you run with that esc?

What's is your FDR (Final Drive Ratio)?

How long is the straight in your track, maybe your gearing is too much or not enough when it reaches the end of the straight...???
