The only thing I've done differently is I pulled the case away from the wall....it wasn't that close, but it sits underneath my desk, and the fan blows and hits the top of it while the back fans are about 4-6 inches away from the wall....could that have anything to do with it?
Little things like that CAN make a significant difference.
Although it still looks like the AC Freezer 7 Pro isnt performing as well as it should be.
It's time for a jiggle test (with the power off and everything cooled down of course) to check the cooler is securely attached.
Look for any sign the cooler might not be sitting level/flat on the CPU. Check to make sure one edge isn't higher or anything like that, nothing in the way of it sitting flat.
What is keeping you from running the cooler in the more typical position - blowing through the heatsink and out the back of the case.
