I have that combo (check my sig) My temps are
24c ROOM
23c CASE
39-44c IDLE
<50c LOAD
And this is on the Gigabyte GA-7DXR which tends to give a more accurate (higher) temp reading.
And it is SO much nicer on the ears than my fop-38/delta.
It was easy to fit also, great HS. A little weak, might get a bit bent in the post.
Peace
