IP 35 Pro: How do you check the Northbridge/Southbridge temps????

[mjavid]

Hi,
The uGuru utility gives CPU, system and PWM temps but no NB/SB temps like the Intel Desktop Utilities, unless I am missing out something......

IP35 boards do not provide NB temp. If you cannot touch the base of the NB heat sink for more than 15 seconds, then it's probably too hot. ALL P35 boards will require active cooling at NB and MOSFET if you're going to push a 65nm quad north of 3.2GHz. Fancy fins and heat pipes don't do JACK without cold air flowing across the heat sinks. That's why I run a Big Typhoon with at least one 92mm Zalman fan (from the 7000 series CPU cooler) bolted to the BT's 120mm fan screw. The NB and MOSFET heat sinks are luke warm when this 92mm fan run at 2600 rpm.

why do you say that? my ip35 pro has no problems running a q6600 @ 3.51ghz, completely prime95 stable. no need for active cooling unless you have stability problems.

Prime is just one benchmark. In general, if you cannot touch the base of your heat sink for more than 15 seconds, then it's probably too hot for extended use. I had an IP35 Pro. Without any air circulation around the NB, my E4300 @ 3.46GHz will push the base of the heat sink to 58C. Temp is measured with K type TC. NB voltage is at 1.25V stock. Part of the higher temp is due to the hot PWM circuit. IP35 Pro shares the same heat pipe for NB, SB, and PWM.

prime95 is more of a stress than what 99.9% of users would put their machines under.
