P4T533-C: Cooling the Northbridge?

[Scipionix]

It seems that while my CPU is adequately cooled, the MCH on the P4T533-C is not. It just has a small heatsink that gets very hot to the touch, so I wouldn't be surprised if the chip reaches 60C or more routinely when using PC1066 memory. I am wondering if that might cause some stability problems. The problem is that standard chipset coolers wouldn't fit since those use two pins to attach themselves while the existing heatsink is held on by two tongues inserted under metal loops. There's a picture of it here.

Any ideas on how to improve this short of gluing something on?

So if I do decide to glue something on, do I glue one of those copper shims on top of the package and around the chip, then glue the heat sink to the whole thing?

what is your northbridge temp that you are so worried about it?

 

[Scipionix]

don't know, but it's damned hot

 

[THUGSROOK]

dont you have a working moboard temp?

 

[Scipionix]

I do, but I don't know what it's supposed to be measuring. it stays below 40C. It can't be measuring the MCH, becacuse that heatsink is well above 40C, so by the laws of thermodynamics the MCH can't possibly be cooler than that 🙂

Umm... Have you measured your northbridge heatsink temperature using an external device? How do you know if it is 60C?

 

[Scipionix]

No, I really should. I'm not afraid of frying anything, but I do wonder about stability. How's hot is yours?

You guys have a good point. My Notrhbridge is not too hot with PC800 but it gets hotter with PC1066 (Which I can still not get to run completely stable). I will run some prime 95 torture test tonight and slap an external thermomiter on that bad boy...
