I've worked at a couple of jobs (telecom, semiconductors) with environment chambers and equipment of that ilk. Heat guns were a common bench testing tool.

Fast forward ten years and I'm doing contract work for a local company. Of course the contractor got the shittiest workstation, which dies every afternoon like clockwork. So I move the POS white box away from the window and out of the sunlight. "Magically" it only crashes once week. So I send a ticket into the queue, stating the obvious, then the IT folks quibbled and finally admit the motherboard needs to be replaced.
