Ok,followed the Abit mobo instructions on installing heatsink and fan which are(thermalright AK-7 & thermaltake 80mm smartfan). Carefully put on my arctic silver 3, installed heatsink & fan,checked that the heatsink was flush and not cocked on the cpu. So,I put my KR7A-RAID in my new antec case and start installing the screws and then I see a bad problem! The top left mobo screw mount hole is located under the top left corner of the heatsink!! And I can't get in there with a screwdriver to install the screw!! WTF, they say to install the heatsink in the mobo BEFORE it is installed in case,then I can't install the mobo screw near it!! So what do I do now? Anyone else have this problem? If so,what did you do?
