Ok, will do that tomorrow when the new case arrives in the morning, I'm changing from my discontinued Antec model (something 300?) to the Corsair Graphite 600T White, mainly for space and cable management reasons. If my current setup is stable for this evening and overnight I will then try what you suggested, fingers crossed. I'll update on progress.
Just saw your edit. I would switch HT on but the temperatures will probably go up by 10 degrees or so, unless I can reduce vcore enough to compensate, again this can be tried tomorrow.
