Summary: I am sure this DX58SO2 will be super stable like my 975XBX and DX58SO, which are still in operation. For the DX58SO2, Intel got rid of the fan on the IOH chip. This IOH chip was running about 90 degrees C for me at first install. Games were being interrupted by pop-ups whining about the high temps. I had to replan the airflow for my case, and move my video card away from it. The on board Marvell SATA III controller has been useless for me.
