Any reason not to drill holes to ventilate inverter?

My cheap-azz HF inverter overheats easily when it's out in the open air and nights are freezing. In new van build, I plan to have an actual electrical cabinet. The inverter is going to freak out...

I had a couple of 900 watt UPS units at work that had the micro fans die in them. It wasn't worth buying a couple of them just to have them die again. So I did the next best thing, I took a 2" hole saw right above the regulators, cut a nice hole then drilled a couple of exhaust holes. I bolted a small fan on top of the UPS and put a foam filter on top .It has worked like a champ for a few years,
