You mean the chipset.

The Northbridge is on the CPU, but I get your meaning. Which chipset, exactly? The one under the CPU socket, or the southbridge heatsink (by the PCI slots) ?

If you're overclocking, set the Northbridge (chipset) and Southbridge voltages to stock (make sure you don't touch the CPU-NB by mistake), and disable the integrated graphics if your board has it (I don't think it does, from memory)

Thanks, the one under the cpu socket. I had overclocked my cpu-nb to 2400mhz and 1.3 volts. I have removed the overclock but it is still really hot

You shouldn't need 1.3v for 2400MHz, I only need that much for 2800MHz. Try the CPU-NB at stock speed with auto voltage.

Yeah I have been running it stock with stock voltage for about half an hour but the heatsink is still extremely hot

With two cards running I wouldn't doubt it. (This is really the only purpose for the northbridge chipset - providing PCI-E lanes).
Check the tightening and see if there is a way you can check the exact temp (i.e. sensor). That it's hot probably means that the heatsink is tightened well and actually taking the heat from the chip, though.

Do you have Cool'n'Quiet enabled? It'll be fine if your overclock is stable. Otherwise I would suggest leaving the system off for a while, or overnight, and seeing what it gets like if you let the system idle for ~15 minutes.

Thanks guys the overclock is 24 hours prime stable. It seems loose but the fact that its hot I guess means that the heatsink is doing its job

The sink probably seems loose because it uses those plastic spring loaded push pins, and only two of them at that. One on each side. They also have thermal pads rather than thermal paste under them. Changed it all over to AS5 on my old boards. Haven't fiddled with them on the Fatal1ty as they have a good mounting system, not loose or anything.
