Hitze Sahne?

Maybe "heat conduction paste", better (IMHO) "thermal paste"?

That means nothing. over approx. 50C ever thing ist "hot".

It depends on which tuner you have.

I have no boards with Alps Tuner found, where the cooling strip 
touches the chip below at all! They all have a 1..2mm gap of 
"pure air" between chip and "heat sink" strip.
It seems that the shielding metal boxes were made for 
other chips sets too which require(s/d) more cooling.

Older tuners may comsume more power and generates more heat.

I have attached a little 40mm Fan between 12V and 5V (Red=12V, black=5V)
so it runs very silent with 7V and have placed it over/between the 
two boards. But i think i can remove it: The card it self was broken.
