I've had the EZ Peak Plus since Christmas and I love it, but this past weekend, the fan made an awful noise when it started charging. I understand that some of you here experience this and that it goes away after a couple of minutes, but it persisted, and I believe it took longer than usual to charge my batteries. Is this worth calling customer service over, or is there a way I can remedy this myself? I noticed they sell the fans themselves, and in order to change that out, someone would have to open it...wouldn't that void the warranty? I've learned from my mistake with the previous Slash 4x4 battery and would rather play it safe this time.

Of COURSE something like this happens when it starts getting warmer out.
