Northbridge temps 90c-is that bad?

Hey guys,

I was using HWmonitor to monitor psu load and temps. Looking at the attachment (attached) my core 1 and core 2 are around 40c at load ( TMPIN0 and TMPIN1, confirmed when entering bios after restart so cpu is still hot)

But TMPIN2 is at 85c but 90c load, I am sure this is the Northbridge as when i touch the heatsink after shutdown its REALLY hot.

My northbridge right now is undervoltaged as well as my cpu...

Any help is greatly appreciated with a dose of rep :P

happy solving!

PS- cant reapply thermal paste to northbride those darn clips are fixed tightly.

If i were you I would contact the Manufactuer

Those temps can't be right and if it is that hot something is defective

max temps i seen on board and cpu socket were 50c at best you are exceeding it by almost 40+c nothing good about those numbers

Thanks for the quick reply, I will contact gigabyte today, and i found some pliers to see if i can get off the heatsink.

Ouch! That is hot. And you are quite right to be concerned, as that is uncomfortably hot. I note that you only have an 80mm fan for your case cooling, and I think that this is probably insufficient. If you can clean any dust/detritus from the heatsink fins and improve the cooling, you might be better. Temporarily remove the side panel to allow better air circulation.

What I would do is restore everything back to default settings (clockspeeds/voltages), power down to allow the system to cool down fully (might take some time, given those temperatures) and then power back on. Don't run any programs except for HWMonitor and let it idle. How are the temps, particularly TMPIN2, reading over time? What does it show at startup, after 5 mins, and after 10 mins ?

Hi all,

I should be able to cover everything in this post, i am using my laptop,

firstly: putting my hand on the northbridge heatsink its boiling hot, its the hottest thing to touch in there even beating my radeon card. cpu heatsink is cool to the touch,

secondly, my can can only accomodate 3 fans all 80mm only. I have a fan blowing air in at the front and its pulling more air in than the 80mm fan at the back can blow out (i heard that is the best thing to do)

thirdly, I reset the voltages in bios to default and at idle they were the same 80c~ for NB and 50c~ for cpu (voltage increased to normal so hotter??? i load furmark for load and the temps actually went across 95 for NB and 60c for CPU which is not overclocked.

fourthly, i used my pliers to remove the heatsink and there is a good ammount of thermal paste on it, with silver particles.(guessing ac5?)

LASTLY

the NB shared an IGP the HD 3200, however i use a discrete card so it should not be in use, and its disabled in bios...


I think i covered everything

you have to ring and see what they got for ya, it is incredibly hot, has it always been like this?

To be honest im not sure, that heatsink has always been hot when i touch it after use, like hotter than others, ill put up a ticket on their site

Thank you and you're welcome !

Now that you've got the heatsink off, make sure that you carefully clean off all the old TIM from both it and the chip itself. Reapply paste and resit the heatsink (after cleaning it out) in exactly the same way as you would with a CPU.

I would also address your cooling. Does the exhausted air feel cool, warm, or hot? Having more air entering the case than leaving is not necessarily a good thing, as my opinion is that it should be balanced. Fans should not be used to force air; rather they should be used to assist the natural flow of air through the case. A simple analogy to the arrangement you have, where you have more air going in than out, is a simple bicycle pump. If you hold the pump at the bottom end where the hose normally attaches (but not blocking the hole) and pump away, you will notice that it remains relatively cool. Now block the hole with your thumb and pump again. Notice how it starts to warm up quite quickly. The same thing also happens to PCs if the cooling system doesn't function effectively.
