Northbridge Problem

post #1 of 5
Thread Starter 
Hello.

Its my first post here

My problem is that a northbridge cooling on my motherboard is a little bit loose.

Now my case have really good cooling and Airflow overall, so my question is whether the is an option of monitoring my Northbridge temperature?

Im worried that because of it being loose my northbridge can overheat, and for obvious reasons I wouldnt want this to happen.

tl;dr version: How to monitor northbridge temperature?

What if you touch it? But if your heatsink is loose, they (heatsink and chipset) wont have the same temperature, the HS need to be tight on the chipset or it wont do the job properly.

I don't think its possible to monitor them ?!?!?! Correct me if Im right but you have an UD3P??

Yes I do have the UD3P.

I dont care about heatsink temperature, I care about the chipset temperature, I just want it not to overheat.

My heatsing is not like really loose its just that when I touch it i can tilt it about 15 degrees up and down.

That's normal, it uses the spring clip system and then tend to wobble about. That's because the area on top of the chip in contact with the heat sink is rather small and is NOT the whole surface of the chip. There is a small black foam spacer that helps a little.

I am always a little confused why both the NB and SB chips have such a small surface area for the heat sink to sit on for heat transfer. If these chips had good heat transfer surface like CPUs, cooling would be more effective making overclocking more fun.

Anyway...

What you can do is remove the heat sink and add a plastic washer on both the poles just above the spring. This will stop it moving about so much.

I ended up replacing the stock heat sink for a Zalman ZM-NBF47 (flower) heat sink, and after some modifications with a Dremel it fitted just nice.

1. The ZM-NBF47 plastic polls are too narrow to grasp the UD3P motherboard holes so I used the stock pols and widened the bracket holes that came with the ZM-NBF47.

2. You MUST remove the black square spacer found on the bottom of the stock heat sink and attach it to the replacement, be very careful not to damage it. This provides the heat sink with a little stability and makes the heat sink sit square on the chip.

3. Two plastic washers reduced the heat sink wobble to zero.

3. Remember to replace the thermal paste with something better, and not what Zalman supply with the heat sink.

The Zalman heat sink is still hot to touch after many hours 100% load, but I think its a better heat sink.
