Thermal intelligence needed

Vertical mount and leave the cover off. It'll cool better like that than with the fan and cover on.

Sounds like the cheapest and easiest solution yet.

Run 2 fans - split the wiring and run half the voltage on one and half on the other. I have done this heaps to quieten the cooling but maintain air-flow.
If its a sealed unit you can even have an in-out setup so that airflow through the unit is guaranteed.

I don't like the idea if leaving the cover off something with an exposed AC power supply but up to you.

PCB's also make good dust traps........it's in a box for a reason.

Think I might just bite the bullet this weekend & run it with fan disabled, see how it does.
Think I'll 1st get a benchmark temp of the heatsink with fan running, then I'll disable the fan & see how it fares in relation, reckon I should be safe to let it rise by upto 15º or so over benchmark (dependant on where benchmark sits).

Probably be fine until summer. That's when I start having problems with some stuff.

Leave it where it is and put the kid in the closet.

Just incase anyones interested, I did get round to carrying out my tests i.e. idle w/ lid & fan on vs idle w/ fan & lid off.
with the fan & lid on the heatsink registered about 22-24ºC after a day of running
with the fan & lid off it registered around 50ºC after 10-15mins

I decided it best to leave fan & lid on for time being

Yeh that is quite a difference, but for thouroughness we require you to test it with the case on, fan off, for a whole day
