A few years ago the company I work for installed suppressors on the Inergen system. It did trigger from time to time, which was tracked to the humidifiers. And yes -- it did destroy harddrives because of the pressure/sound waves before we installed the supressors. Haven't had any incidents after we fixed the humidifiers. But Inergen (and other gas) is more or less useless if you allow it to escape too quickly. So the cooling system should be a fairly closed circut. Edit: I'm also a Norwegian dude. :)
