Try the PandaBoard VESA MDF - although the modes are the same the
timing is slightly different which might help.
You should have no problems running 1920x1080 @60Hz without artifacts
- I was running Project cool all day last Saturday at the Wakefield
show with no issues.

That is a sign that the video is being pushed over the limit.

I don't know how recent the current PandaLand ROM is (i.e. whether it
has SmartReflex enabled) but as long as you're not going above 1.2GHz
you should be fine without the fan.
Just make sure you have !CPUTmpMon always running. If things start to
get too hot (north of 75°) over the summer you can always just
reconnect the fan. As it is a PandaBoard will shut itself down if it
reaches 85° anyway.
I hope this helps.
