460 on load get into the 70c area from reviews i've read.
Can someone confirm the reference cooler blow in or out. When I did test on a cpu with a heatsink fan blowing on the cpu it was noiably higher temps than if it sucks air away, like i said an odd design for reference 460 so i can understand msi and gigabyte creating a custom cooler.
Not meaning to be rude here but i can't really make sense of anything you're saying. The reference cooler blows out of the case at one end and into the case at the other. MSI/Gigabyte blow 100% of the air into the case.
Unless you have bad airflow in your case neither method will cause any problems.
