not ohbe adapter

Yes, this is possible. See also Product Page -> Specifications -> Show More -> Processor Socket (Second to Last Entry) Manufacturer page: https://www.alphacool.com/shopware.php?sViewport=campaign&emotionId=2632

As far as I know, only a radiator up to 240mm fits inside. A 360mm only fits in the front.

Yes, that fits.

Good morning Adehner. Do I understand correctly that you want to cool both at once with an Eisbear? Unfortunately this is not possible in the configuration, you would need a second water block for the graphics card. Since there are no full cover blocks for the V7900, you would need a universal block like this one: http://bit.ly/2voU22O Then you would have to provide the voltage converters and RAM chips with small cooling plates so that they don't overheat due to lack of cooling, like this: http://bit.ly/2uMFExE . All in all, it would not be an elegant and simple thing to do. Another option would be a separate small all-in-one cooler like a NZXT Kraken X31 (http://bit.ly/2uu58oa), equipped with a NZXT Kraken G12 adapter (http://bit.ly/2uMAuBH , unfortunately not available at Digitec), which has a small fan built in to cool the voltage converters and RAM chips. But I can't 100% guarantee that the Kraken adapter will be compatible with your V7900, older FirePro cards are always tricky about that... Hope I could help at least a little bit. LG Tamerlan

I would not recommend that. The pump is not designed to cool so many components. With an additional Eiswolf cooling block with integrated pump, it might work. The cooling block certainly comes with a 120, which means that another 240 with a suitable connection is needed. However, I recommend a custom water cooling system with so many components that the pumps will probably run at their limits. I have only used the Eisbär myself and have also switched to custom (temperature/volume is better).

Yes, that also fits the LGA-2066 socket.

Contact Digitec Support (Digitec@Digitec.ch) directly with your request. You will most likely be able to return the additional holder.
