Is that normal? My CPU heatsink reads Nero... I suppose it's one of the lowest tiered cooling system?

EDIT:
There are many voltages settings that are set to Auto, like PCIE, QPI PLL, DRAM Termination etc. Should I set those manually as well?

EDIT EDIT: Minor success: I set everything manually except for some memory settings that I have no idea what they are, and set bclk to 160MHz. I have been running OCCT for about 5 minutes now, and so far no overheating has occurred. But core 2 seems to hover dangerously close to 100C, with a minute or so reaching 100C, while the other 3 cores hover around 90s. I should be concerned about reaching these temperatures right? A friend once told me that high end GPU of the series like the 280 GTX I am using should be watercooled, is that the reason I am getting high temperature for my CPU? My GPU seems to be running at around 54C only...
You should back down with the Vcore seing the one core at 100°C. Other cores around 90°C indicates the TIM (Thermal Interface Material) was not properly applied and not providing good contact CPU to CPU Heatsink.

If you change the BCLK from defaut 133 to 160, you should increase QPI/Vtt voltage a bit. Memory bandwitdh is BCLK x Memory Multiplier, 160 x 10 = 1,600 MHz. Memory at that speed the VDimm Volatge should be set to what the DIMMs are rated such as 1.65v. Have to physically check what is printed on the label something goes like this 1,600 MHz 8-8-8-24 CR2 1.65v.

GPU hovers around 54°C at 100% GPU load is very nice, but is it?

Most likely its your fan thats causing the heat problem, check your bios to see if you have it set to auto(temps rise=fans spin faster) or to a set voltage(temps rise=fans stay the same speed). It could also be the thermal paste not applied properly or too much thermal paste. I would suggest getting a new cpu heatsink/fan.. these cpus run hot and like i said before in my earlier post the max themp intel says is 100C and you generally wanna stay in the 70-75. But, even with my old cooler(which was not stock, but was not good) my max temps would be 83C running prime which i thought was still high but i didnt have money for a cooler.
As for your ram many ram advertise their max speeds, for example my corsair dominator says its 1600 mhz at 1.65v(which is considered to be an OC) and the max speeds at STOCK voltages is 1333 Mhz at 1.5v which is what it really is.
PCIE should be left at stock voltages, qpi/ppl could be set manually but auto usually does a decent job. The only thing that i can think of to set manually is your DRAM voltage.
