Not monitored my CPU temp @Rroff but then again I have an AIO on it so wouldnt be as affected as the air cooler. Will report back if you remind me - I bought a new m.2 for the fresh install of windows so take a while till I get the build back on point.
That is my setup - used to have an Antec Kuhler AIO in there but it had a few issues and I wanted less noise.
