I have a Gigabyte GA-MA790x-DS4 and the northbridge reads out in hwmonitor as 79*c-80*c never changed always hot. The passive heat sink is warm to the touch. I have been running the board for about two months maybe longer. No issues yet its unsettling having a temp that high. I think also if I could cool the chip I can get my CPU temps even lower. Here is a picture of what I have going on. I have my gfx card in the top pci express slot now and a 80 below it for exhaust. edit:cable management is a lot better. Sorry for the older pic (sall I had) This is about what my temps are all the time. Excluding the gpu temp. So any suggestions would be greatly appreciated.
