Re: Crappy power supplies! GAAH
Ooooh... that sounds familiar. Sleeve bearings (or similar).
I worked a few years back for a certain video conference equipment manufacturer (since borged) in their reverse logistics group and noticed a pattern of fans failing on a certain popular and high-end model of codec and did some investigation.
And they all began failing at once all around EMEA and APAC on codecs of a certain age. I alerted our service centres at the time to stock up on replacement fans (with ball bearings) and informed our R&D and production groups about the epidemic. I don't think they cared because the up-front cost was less for production - they didn't care about the back-end cost for repair/replacement as that didn't affect their budgets, despite it being a higher cost to the company in the longer run.
Icon for the system temperatures of some of the units. Our service centres sent me occasional photos of various faults for shits and giggles... many of these in a lovely shade of toasty brown.
