Just put together this new computer, no overclocking, cpu die is at about 51c at idle, gets up near 60 under heavier loads (RT 1 at 35-39). I've got the Codegen 6209 case (air duct for the cpu doesn't match up with where the heatsink & fan are, so I took the duct off), and ever since I finished the build and put the case back together, the fan is running constantly at top speed. It wasn't when I had the panels off, but I wasn't getting a temp reading then so I don't know what the difference is. Am I in a safe temp range?
