I like the rubber band idea, never thought of that :) As far as the screw extractors, you won't find one small enough - I know cause I had a similar situation several months ago.

If you can grab the head, which is unlikely, I always use a needle nose vice grips pliers.

Not familiar with Ricks left handed drill bit, but if that doesn't work you're basically left with drilling the screw out. Select a drill bit just slightly smaller than the head of the screw and carefully drill until the head spins loose of the screw body. Carefully remove the air cooler and then use a needle nose vice grips to spin the screw out of the hole. Works like a charm.

Only problem is you'll be short 1 screw when you put it back together, but that should not present too many problems.

Using a left hand drill bit spins it in the direction (counter-clockwise) you need to remove it. Many times once the bit bites it will back the screw out without any further assistance.

Same happened to me, I drilled out the post of the screw with a smaller sized bit and pulled it off. Just be careful not to slip and rip off a bunch of resistors or chips.

Thanks a lot guyz for the suggestions, Rubber band didnt work, nose pliers didnt work since there is virtually no space between the head and pcb to hold it.

Will try the left hand drill bit idea, would have to see if I get such small drill bits in my local area....
