Hobbywing 8bl150 slow fan speed

[Caleb90]

Ever since i put this esc in i thought the cooling fan was slow. All my other esc fans rip right along and you can hear them working, not this one. Running the truck today and 10 min on a 4s pack and it shuts down. Let it cool for a bit and it ran for 5 more min anc shut down. Was about 80 out. Thinking the fan is a dud, replace with some thing on my own or try hobbywings warranty?
