Medusa Afterburner V2 BL motors

Anyone have temps from running stock, and then again after the holes are covered up? I'd imagine there would be some rise in temps covering them. Instead of using tape on the rear, how about some metal screen instead? Would keep the larger stuff out yet allow air to circulate. Of course, some dust would get in there, but it's the big stuff that's a problem...
