Thanks! I am now concentrating on 240. Maybe 240 + 120 by using Alphacool Eisbaer.. This maybe possible using a small graphics card, viz. MSI Geforce GT1030 passive.
Thanks 1...1! The 240 mm Eisbaer will be place on the bottom after removal of the USB and "music" contacts. An extra 120 mm radiator+fan will be placed on a wall. All to arrive at a good cooling of the 7980XE.
