I normally use an el cheapo Radio Shack indoor/outdoor digital thermometer
to monitor the exhaust temperature from the PSU when fooling around with
various fan RPMs in my quest for less fan noise. Typically one should
monitor case, CPU and PSU temps when doing this. That was the scenario
yesterday when it dawned on me - "Isn't there a TRPWR header on this board
and on past Asus boards just a 10K NTC thermistor suffices". Well, long
story short, I had it up and working in about two hours, had all the parts
already as leftovers from other projects, biggest problem was finding them,
didn't have to buy a thing.
Here's a shot of the 3 foot probe (thanks Asus for placing the TRPWR header
as far from the PSU as possible);

A close-up of the thermistor firmly stuck into the crimp connector housing
(this avoids soldering);

And sensor end of probe strapped to wires in the PSU;

Radio Shack sells the thermistor for those interested and the rest of the
probe can be made using the front panel LED or switch wires from an old
computer case. PSU temp will be picked up automatically while in the BIOS.
However, if monitoring using MBM 5 then use MBM 5 "Sensor 3" (rename to PSU
or whatever) and display "Winbond 3" board sensor.
