Mosfets in full load could have 100C specially with high voltage at CPU and CPUNB. If you have CPUNB at default clocks or around, dont need 1.4V with CPUNB. This is only for high stability CPU and CPUNB clocks around 2600+ MHz. Its necessary cooling VRM with some cooling. Zambezi Bulldozers are with high voltages very power hungry (Vishera is better after OC, no need so much voltage for the same clock at CPU an CPUNB). Similar as i7-3960x after OC. Watterblock was only at CPU? If yes, its clear, with wattercooling setup you need always cooling VRMs (some 120mm fan or so). IF you have classic aircoller at CPU, with normal middle OC its good, because in most cases CPU cooler cooling VRMS a bit too (air flow direction).
LLC is better to set manualy (high). C5F and C5F-Z are different with real voltage and voltage in BIOS.
Guys, if you are overlcoking, in every case monitor the temperatures not only at CPU (in
Coretemp max 65-70C! No more!), but power suply rails and VRM temperatures too.
