Tomorrow I will be looking at a customers 12+ year old PC whose CPU fan is dying (again). Reportedly they have replaced it a number of times from a manuf named 'Kingston'. Don't know if this is the memory Kingston or not. This is a critical function PC (controls heat, a/c & alarms for a major portion of a major university.) The PC is being phased out, but is still required for months to come. I will have more details forthcoming, but wanted to cast a line to see if anyone may have sources for OLD cpu fans. Sorry, I don't even know what manufacturer to specify: Supposedly this is an old IBM PC that runs OS2... And of course, the customer is VERY antsy!!!
