Northbridge Temp?

[FooAtari]

Hi,

On my overclocked system my NB temp can be as high as 50 - 53C when playing
games. I have run stress tests several times and it seems stable enough
but I am worried temps this high might be dangerous... What do you think?

Thanks

In an Intel datasheet, one of their Northbridge chips has a
Tcase_max of 99C. So the chip can likely be run hotter than
50C and still work. (Not all chipset makers provide tech data,
so I have to go with Intel info to provide an example.)

You can always get an aftermarket cooling solution for the
chipset, and use that. Read the reviews, to see what other
people think.

Thermalright HR-05 family (no fan included)

It could be, that just pointing a fan at the existing cooler,
might improve things. Since we don't know what motherboard this is,
it is hard to say what kind of cooling solution is already on the
thing. For heatpipe coolers, a little auxiliary airflow might be
all that is needed.

Asus P5N-E. Already using a HR-05 with a 60mm fan attached and still
getting those temps... Im thinking that the paste hasn't been applied
correctly. I might slow it down a bit until I have time to remove and fit
the heat-sink again.

Experiment with the fan speed. If the temperature does not move from
its current value, it could be that the sensor is not measuring
the Northbridge temperature. I'd want to verify it is really
measuring the Northbridge temperature, before trying to find
another solution.

The results here, on another Nvidia chip, seem to be pretty good.

There are a couple ways to measure temperature. If the chipset
device has a thermal diode inside, they can connect that to the
monitor chip. If the chipset has no thermal diode, a separate
thermistor can be used, but it would not be in direct contact
with the chip. I'd want to try some tests to verify what
exactly is being measured and/or displayed. Sometimes the
displayed value is just crap (i.e. not a sensor value at all).

I'll check when I have time, but im pretty the temps do drop with higher
fan speeds.
