I've received several complaints by people concerning the Optiplex GX620 Fan speeds. I've analyzed the systems and it seems that bios has no controll over the fan speeds, so the fans spin out very fast and very loudly. I've had a similar problem with Optiplex 320, and I found out that the temperature controller in the front panel was faulty. The difference between the Optiplex 320 and GX620 is that Optiplex GX620 doesn't have the temperature controller embedded in the front panel, so I don't know whether it's the same case as Optiplex 320.
Any ideas on what might be causing this problems and how do I resolve it.
P.S. The strange thing about this is that I'm getting complaints from different people, so it might that the entire shipment or, in the worst case the entire series, could be faulty.
Thanks in advance!
