Why is northbridge so hot

Open air coolers are great at keeping graphics cards cool when they're sitting on a open test bench, but not at keeping your case temps cool or other things located next to them when they're in a stuffy case. Pholostan Gerbil. No problem though, they can take a lot of heat. Made with more than double the process node of the CPU, temps at 70 C is no problem.

On my series motherboards, the NB heatsinks are always to hot to touch. Under prime95 load the sensor reports about 50 C and the metal is over 70 C.

I've never been close to that IIRC. Or it is measuring something other than NB temp. It appears that high temp of the northbridge is so by design and nothing to be concerned about.

They don't seem to have an arrow on them like the CPU heatsink pins do to show which direction to turn for removal? Maybe the addition of a small fan Arie doesn't like them because of noise might be easier. Does that mean that it is impossible to 'see' Northbridge temperature?

If there are retaining clips, they should not have used "adhesive" TIM thermal interface material. If adhesive TIM was used, you can usually twist it back and forth and break the bond. This is best done after you have let it run a bit to get warm. Be careful to only apply a twisting force and not a pushing or pulling force.

And in any case, you must hold your tongue right and cross your other fingers. If you think you are applying too much force and it still will not come free, you probably are. If it does have push pins, they are typically in two parts. The pin and an outer sleeve. When the pin is pushed all the way in, it pushes out on the sleeve which then locks the unit in place. You pull on the pin to relax the outer pressure, then remove the pin and sleeve together.

Do you have good front to back air flow through the case. I like at least two large mm or larger fans. One pulling cool air in and at least one, not counting any PSU fan, drawing hot air out.

Is your system still under warranty? I'm also in the same boat. My fans used to make soo much noise sometimes just randomly when the machine was idle but i changed the case fan to a BeQuiet Silient Wings USC fan last week which has made is much quieter unless i'm rendering or something, then it's still quite fairly loud.

Since changing the case fan i've been monitoring system temperatures and it seems my northbridge is also steady at around 80C but this still seems far too hot. This could be to do with the changing of the case fan?

To be honest, the standard fan in this machine was always very loud and not suitable for a home pc there have been all sorts of complains about it in these forums but i did take a risk changing the fan from standard. I wonder if these weird random burts of fan activity i used to have were to do with the cooling of the northbridge - certainly wasn't CPU. What are you using to find the temp? Now it reads 60C. I'm not saying this is a fix but it could be that this sensor reading is the accurate one.

It seems to be the case for the second sensor also because when that is set to Diode it reaches C so must be inaccurate. Got approx. What is confusing the most is that in fact North Bridge seems sooo hot.

Heatsing itself definitely feels lot hotter than 40C and possibly closer to 80C.
