Just received my X35 and so far pretty happy with it - the picture is great and fortunately none of the dreaded flickering. My biggest gripe is the fan control (or lack thereof), the monitor is dead
silent until it suddenly decides that the fans need to spool up to 100% for no apparent reason (it can happen after the monitor is on for 10 minutes or 100 minutes). Once the fan cycle starts going it doesn't really stop, but rather goes from 0% to 100% in an infinite loop. I wouldn't mind if the fans were on all the time, it's the constant shift in fan speed which drives me nuts.
So, can any Acer employee comment on whether this is either a) working as designed. Or b), a known issue which can / will be fixed with a firmware update?
