Any idea what hot northbridge temps I should "watch out for" on my Asus P5N-D? I have an Asus hardware monitor on my desktop, so I'll be watching my northbridge temps. There is a stock Asus heatsink on there now -- I'm assuming that I'll need something better once I get the overclock to work, but maybe not.
I believe that's a matter of personal preference until 90c. I don't recall seeing any recent motherboards that let you set the alarm any higher.
Also Fire-Flare, u mentioned u have the Thermalright HR-05 SLI on your southbridge... I'm a noob, but isn't the southbrudge much smaller than the northbridge? So the cooler is much more oversized than the SB itself? I've never heard of people cooling their SB's. I have a smaller stock heatsink on there now. I don't think that I can monitor my SB temps.
Not necessarily, both chips have been the same size on my AMD boards for the last few years, but the NB runs at a higher clock rate than the SB because it's linked to the 'fast' components while the SB is in charge of the 'slow' ones.
Regardless, my SB reports to be at room temperature while my NB is currently 65c with a http://www.enzotechnology.com/cnb_s1.htm
that gets almost zero airflow under my CPU cooler.
