Sorry for late replies, at work here.
The RAM usage was probably account of Chrome tabs, my game and Photoshop to chew the screenshots up to send them, I haven't had any RAM based issues, though the low frequency in screen 5 is curious. I have two Vengeance sticks in there at 1600 MHz, but they seem to be running slower.
As for cooling, yeah I have two Noctua fans on my heatsink that keep the CPU ice cold, even when overclocking it. I also sleuthed into the issue a bit more.. People are reporting the fan controller failing on the Graphite 600T cases, so that may very well be the issue. I'm going to see if I have on board fan space I can use instead and see if that fixes it.. Though it does seem like when I get my new cpu/mobo upgrade, a PSU would be in order, costs for them are low now anyway.
And I linked the PSU from Newegg, if that asking on the brand was an oops. ;p
Also just hit me. I have low volt adapters for the two fans in question.. Should I try swapping to these lower volt/lower noise connectors when I get home and check, as a temp solution?
Another edit, the GTX680 has a 6 and 8 pin connector for power on it, my PSU has a small 2 pin to connect up to the 8 pin.
