Wow thread resurrection. But thanks.
Air's not a problem, even on low speed it moves a ton. Sits on a window ledge behind some curtains and benefits from cold air leaking in from outside (wooden frames). Pulled it out for maintenance yesterday funnily enough. 9 months of dust, always surprises me how much builds up. Didn't effect the temps though, anyway soon removed with some compressed air.
Definitely recommend radbox's after using this one, if you have the room for one, certainly keeps the case end simpler.
