Default Re: Advise on strange noise

The noise sounds like a small fan with bad bearings/bushings in it and after it ran for about 2 minutes it became the sound of a normal small cooling fan. I let the car sit for about 1/2 hour and turned the ignition back on and could not hear it. My car has been in storage all winter and this was the first time I turned the ignition on in months. I'm going to the dragon run in a few weeks and would like to know if this is anything to be concerned with.
I noticed the same thing on mine.
There is a fan that cools the ECU box on the passenger side

Noise before the engine start .

Noise in or under the ECU
