This will take a proper PC Geek to please do help if you are.

I have as a motherboard:

ASUS Rampage II Extreme (1 PCI, 2 PCI-E x1, 3 PCI-E x3, 6 DDR 3 DIMM)

QuadCore Intel Core i7 940 3066 MHz

My problem:

My northbridge is now registering at 91 C/ 196 F

This caused my PC to close down instantly, when it went above 90, until I went into the BIOS and turned off the automatic shut down.

So two questions:

1, Does it matter that it is that hot? I am monitoring it now, it is hovering at about 90-91

2, Anyone know anyone capable of coming around and fixing it, if it is a problem that needs fixing?

As this is new and it did not happen before, I am thinking it needs fixing.

Since it is still working, it will require someone to come around, and check that the Heatsink is all together properly and perhaps renew the paste that holds it down.

I can’t let the PC go away, it would need to be done here. Or else I would take it to a shop. Don’t want a random freak off the internet, would like it to be someone who knows someone I know.

Thanks for reading this incredibly boring post.

Hey mate

I could get some heatsink paste from work and post it to you if that’s any help?

I’m not confident enough to come and start poking around your computer myself I’m afraid…

Obvious question, but you’ve checked all your fans, venting etc yeah?

Yeah I am not confident enough to go inside this machine either.

Used to be ok back in the day, but now it is all this quad core nonsense.

I wouldn’t even know where the Northbridge is to be honest, I had to look up what the hell it was.

I went into the Bios and turned all my fans up to “Turbo” but I also noticed that I have a couple of fans on the PC that have never been turned on. Might be time to turn them on and see if they help.

Temp down to 88 C now, but I still think that is high.

The Southbridge is 48 C which is what I think the Northbridge probably was once.

That’s very hot but probably within spec. The first thing I’d do is switch it off, take off the cover and give it a good blast of air to dust it. Fine dust is a brilliant insulator. Then report back.

Kaos, I can take a look at it for you if you need. But if you need a company to take care of it you can always use the company work for…

Anyway let me know (pm or text me)

does ctrl+alt+ delete not fix it? sorry that the end of my geek knowledge

What fan speed is running your system?

And as you said you are not confident enough to go into the box, it might be as simple as clean radiator itself.
This bridge usually running at higher temp that others, I would start be really worried above 100C, but to be fair 80ish is sort of normal.
Grab yourself a dust cleaning air pressured can, and some heat-sink paste from maplin.

If you want I can pop in and have a look inside.


Hovering about 83-85 C at the moment.

Thanks for the offers, will text Ricco and get him to come over when he has some time :smiley:

862 RPM on the Fan Speed!

That is very low speed of fan. And this is how it will be at 83C.
If you have any manual fan settings try boost it’s speed. As well I believe you may as well use some Greenpeace bullshit power conservation settings :slight_smile:


Also have you tried re-setting the power management settings?

I got called out a couple weeks back to a client who thought he had a faulty-out-of-the-box Mac Pro, because the fan in the PSU was spinning up and humming like mad as soon as he logged in… After talking him through loads of troubleshooting over the phone I eventually had to go down there…
When I got there, I opened System Preferences, saw a third party application had been installed called “Fan Speed Control”… I’m sure you can guess the rest :crazy:

The northbridge itself won’t have a fan on though, will it?

Kaos, are you saying there are two fans mounted in the case, but they don’t spin? I would suggest they need connecting to power if that’s the case. It should be quite simple.

probably poorly applied or cracked thermal paste between the northbridge and it’s heatsink as Conrad says.

It’s pretty easy to do this yourself - loads of videos on youtube showing you exactly what to do.

My PC is quite cramped in there, and the Chipset has this massive double fan thing sat on top of it.

Bit worried about taking it apart.

The two fans on the front have never worked, dunno why, probably, as you say, not connect to any power source.

I suspect it is the paste, just not willing to take the risk of poking about in there.

This machine has far too much material, and during the exam period, is far too crucial to just start digging around on the basis of a youtube video.

I would also say its time to dust it out.

I’m sure you do, but just in case you don’t then I’m going to say it: backup backup backup. Please. Backup your data. ASAP. Regularly. If you don’t know how to do it, I can help you set it up, just let me know. This is something that is much better done pro-actively.

In the last couple of years, I have had folk come to me with a “dead computer” which has the only copy of their: “entire masters’ thesis”, “all accounts and invoices for the last year”, and “all photos since I started shooting digital in 2000”. The first two I was able to rescue all of the data, the last one I had to send off to a professional data rescue company who were able to retrieve 90% of the files. In all three of these cases, I had previously told these people to back up all of their data regularly, and they didn’t, so I ended up spending a lot of time making up for it.

I’m not saying necessarily that the chipset overheating is going to damage your data, but it’s not outside the realms of possibility. Suppose the overheating affects the disk controller which starts writing data to random sectors of the disk instead of where it’s meant to? Or it starts spinning the disk constantly at high speed, leading to it dramatically exceeding its expected usage cycle and wearing out early? Or…well, anything. I work with large enterprise-scale computing systems, and I spend a lot of time focussing on the non-functional aspects (security, availability, reliability, disaster recovery, etc). Some of the stories I could tell of “wow we never thought that could ever possibly happen but it did” would absolutely astound you…

On backup, always have (at least) three copies of anything important. The copy on your PC, a backup on something physical (external hard drive) and a copy off site (in the cloud).

Off site I mainly use Crashplan for unlimited backup over a few computers in my house -

But also, I have most of my regular documents in Dropbox, or now Copy (see the thread I made a couple of days ago -–cloud-storage-dropbox-clone )

Are google and cloud really secure enough for confidential information?

I am performing a back-up now, looks like it might take awhile.

Kaos. If you’re concerned about cloud storage I have 4tb on my drobo. So if you need it give me a shout.

If you concern about storing personal/sensitive information in cloud (as you should). Try AxCrypt, it is free encryption software which can encrypt/decrypt on fly.


My back up is 249gb in size…

is that normal Gzus :smiley:
