It is has been a while since I built a system, but as I recall there was always an "X" shaped piece of metal that went under the MB that the CPU cooler mounted to in order to reduce the amount of stress to the MB. This time there is nothing with the stock i5-7600 and cooler or with the Asus B250M-C MB. There is also no mention of the need for one in either set of directions. I would assume then that it is OK to mount the cooler directly to the MB but a confirmation of that sure would be nice. Thanks.
