I have an intel 965 board and the temp on the I/O controller hub is extreamly high.
158-166 F and that's with me doing just normal stuff that keeps computer at idle.
Why is this so high?
Mem Controler 118
Check that all your fans are working, including power supply and graphics card. Consider adding a front fan.
The CPU temperature of 43 Celsius or 111 Fahrenheit appears to be normal. The motherboard and memory controller appear to be normal as well. The only temperature out of whack appears to be the I/O Controller, which may be solved by an additional fan.
