afair the superglue (="Sekundenkleber") is not stable when heated, if it gets to hot your heatsink could simply fall off, special termal transfer glue would be the better choice

btw. yesterday a saw a heatpipe solution as vga-cooler, Zalman ZM50-HP (30 Euro)(http://www.zalman.co.kr/english/product/zm50-hp.htm)
its supposed to spread the heat to 2 flat heatsinks on the front and rear side of the board, because of the missing mountig holes i will try to glue it to the tuner chip of the dvb-s, there will be more work to do (heatsink to big) but maybe next weekend i will give it a try
even if its nor working it could be a good start for experementing with heatpipes
