[vdr] heat problem with 1.3 Tuner? (was: Re: Artefacts on ARD?

No, not "only in the evening". All day long.
But only on ARD, ZDF is OK.
Have they swapped transponder hardware with ZDF? ;-)

Do the V1.3 tuner have a termal problem?
I messure 36C(!) at the antenna plug of the 1.3 card,(Tuner:BSRV2-301A with Loop thru)
but only 31C on the plug of the 1.5 card.(Tuner:BSRU6-502A without Loopthru)
There was a fan @ 7V to cool the DVBs blowing from the slot plugs
(riser card) between the cards.
After adding an extra 40*40 fan @ 12V blowing(!) from the top end
of the cards down to the slots(riser card) the artefacts seems to disappear.
The Temps at the Coax-Plugs (outside) are now:
30C on the 1.3 (upper slot)
29C on the 1.5 (lower slot)
But the box is now much louder :-(
