Are you sure? A Scythe rep/forum mod and a user both said
that the URK 3 won't work with socket 1155, so unless 1156 is significantly different...
It appears that rep backtracked on his advice?
"I have to apologize for giving you wrong information. This problem is that there is no appropriate clip for the cooler side available which has the necessary distance for the Socket 1155 or 1366 holes. I forgot that when thinking about a solution"Also:
"No, it didn't work. I bought the Scythe Universal Retention Kit 3, but unfortunately this has no support for the Ninja SCNJ-1000/SCNJ-1000P at all...
The original Ninja uses clamp mounting and two mounting bars that were supplied with the CPU cooler.
The information that Scythe gave here is wrong: The problem with the the Scythe Universal Retention Kit 3 is that it doesn't support mounting bars. Hence it can't be used in conjunction with the Ninja, only with other coolers that I don't know..."But others say:
"In case you wish to use the original Ninja (which was a great CPU cooler!) and don't throw it away just because Scythe doesn't offer an appropriate 1155 mounting kit, buy a Socket 1155 mainboard that also features LGA 775 socket holes - like the ASRock H67M-GE/HT S1155 M-ATX."
"Dangit, I really wanted to keep using my Ninja - Maybe a TR mounting kit will work with 1156..."
