Running a Xigmatek 1283 cooler which is supposed to be an excellent cooler according to Frostytech database. If I disable all the power saving stuff, I idle at 45C using a 3.5Ghz speed. Loading takes it to 77-78C so I'm thinking of upgrading the cooler.
Xigmatek is supposed to be pretty good. I went with the Noctua NH-U12P SE2. One of the highest rated coolers for the 1156...and SUPPOSED to be dead quiet. We'll find out in a week or so.
Is it possible that you either don't have the cooler installed well, or that the mount is over-tightened?
There are a lot of reports of 1156 motherboards not working right...until people go back and re-do their cpu cooler. Apparently, if the cooler mount isn't torqued right, and over-tightened, it can cause the CPU to not seat properly on all pins...causing a myriad of problems that make it look like bad memory...or a bad board.
From the ASUS forums:

"This thread is a basic troubleshooting guide for users who have memory detection issues.
For example the motherboard is only detecting 4 GBs instead of 6 GBs or 8 GBs instead of 12GBs.
This issue is fairly common on Intel X58 based systems and affects all brands of motherboards. X58 is Intel's first platform with the memory controller built into the CPU. Good contact between the CPU and the socket pins is very important and bad contact is usually the cause of "missing" memory as well as faulty memory and other causes listed here:
Poorly fitted CPU cooler ( too much tension, not enough tension, uneven tension)
Fix: Adjust tension of aftermarket cooler, Test with stock cooler, reseat CPU and cooler.
*Most people fix the problem just by reseating the cpu and cooler* (Take the board out of the case to reseat the CPU/Cooler)
Bent CPU socket pins. (damaged board, poor installation, poor cooler tension, uneven pressure etc)
Fix: Inspect CPU socket for bent pins, some users have been able to straighten the bent pins and solve the problem. Otherwise if its too badly damaged you might need to RMA the board. (Note: Asus might refuse RMA if bent pins were caused by user)"
While that specifically talks about memory issues with X58 boards, apparently it's a problem with the 1156 boards as well.

"Also, be sure to inspect your CPU cooler mount. Over tightening or unequal pressure on the CPU socket can cause the CPU to not seat correctly. Frequently, this translates into what appears to be memory related problems because the CPU/IMC is not making proper contact with the pins leading to the memory sockets. The fundamentals here apply to systems with 3 modules also and especially when overclocking. This applies to P55/H55/H57 also. In any situation where you have these issues and where the above steps do not work, please remove your CPU and inspect the socket for bent pins"
