quick e6400 965-DS3P temps questions

[FishPolice]

Just started overclocking my rig & currently running at 3.35ghz.
Temps according to Everest are:
mobo: 57
cpu1: 54
cpu2: 52

How high can I push these temps? Where is the sensor for the mobo? Is this the NB temp?

I would imagine you can push that a bit more yeah but wait for someone to reply who is better at overclocking than me first I would to confirm it
The sensor for the mobo temp is located next to the intel sata ports right near the southbridge.
To see the real northbridge temp go in the bios > pc health status and change the smart fan control method to intel qst, save and reboot which will also give you a different warning screen to usual which is perfectly normal. Go back in the health status section in the bios and you should see all the temps listed including the nb and sb.
It will be your gtx causing the high temps on the mobo so have another look at your airflow in the front of your case and try a more powerful fan there too if you,ve got one.
Doing that worked a treat for me when my mobo was reporting higher temps than usual.
