Fans are notoriously the most common thing to go bad in electronic equipment. Think about the conditions ripe for failure...spinning on sleeve bearings (if cheap one) at about 7,000-10,000 RPM in usually under extreme temperatures and humidity in a high vibration & shock environment. Military grade fans with ball bearings purchased cost about $500 by themselves...do you think Linale uses them or COTS (Commercial Off The Shelf) grade stuff? Even MIL-SPEC grade stuff have an MTBF (Mean Time Before Failure) of maybe 5-7 Years...at best!
May want to use the SEARCH tab near the top of the HDT page and type in Lenale fan. There has been much said about these fans...Good and Bad...! :s
