Ai Prime - fan noise

[jfmkem82]

I have 2 Ai Primes on my 75 gl reef tank. As of late the fans have been making a rattling noise. Not all the time but sporadically. I know its the fan because if I press on the vented area on the top of the light the fans can be stopped and the noise goes away. When I release the pressure of my hand, the fan slowly starts spinning again and then the noise returns.

Thoughts or suggestions??

I have4 Ai primes and I believe the noise is from the screen on top touching the fan you probably pressed on it too much while cleaning,try to find something small to pull the screen up away from the fan.
