So I bought this used store fixture from Justin a few weeks ago, and finally got the correct leg kit ordered in and got it all fired up.
It's been running nicely for about 3 weeks, I guess. Today, I noticed some fan noise (think it's the fan(s) anyway).
I turned the fixture off at the switches, used some canned air to clean out what I could (they aren't really dirty, just some minor dust accumulation), and then let it cool for a few minutes before turning them back on. This time they are as quiet as normal.
Do I have a problem brewing?
