Overheating northbridge?


I have an ABIT KV7 motherboard and I'm running Kubuntu on a SATA drive. I noticed that my disk performance was slow this past week until eventually last night all of a sudden my entire filesystem was read-only.

I opened the case and found my tiny northbridge fan had died. I replaced it with a huge heatsink today and although my system is running longer, eventually the filesystem slowed to a crawl and then went to read-only mode. The northbride heatsink is barely warm to the touch though.

Could the northbride chip really be this heat sensitve or is it more likely that the chipset is dying? or maybe my sata drive is going bad and the northbride fan problem was just a coincidence?

I have Win XP installed on another drive but it's p-ata so if it doesn't crash I still dont know what that means since it's using a different part of the motherboard.


thanks for any help!

Sounds like the SATA hard drive is going. Did you check the logs.

I hope you replace the northbridge heatsink with a passive heatsink because using a fan to cool off the northbridge heatsink does not work for long.

The Northbridge chip handles the memory and AGP slot but not the SATA. Though it does interconnect to the Southbridge chip which handles the SATA, PATA, floppy, PCI, ISA.

thanks. yes, i replaced it with a big passive heatsink to avoid future failures like that.
i left my system booted into windows last night defragging the ata133 drive and it had no trouble. i'll boot into linux again and check for clues in the logs.

JUST A CLUE

I got the same problem few times with Sata,I tought my system is going down. Well I just give a touch on SATA DATA cable ;seems like a bad interconnect. I plug and unplug the cable then the system going smoothly. SATA cable only stick to the male interconnect not like IDE grips the pin. Make sure its well conected. Norton GHOST sometimes works with UNIX, you can ghost your HDD data and saved for back up.

I ended up finding a good deal on a new sata drive so I replaced the old one and everything is running great now. I'm guessing that drive just was on it's last legs.

A hint: Use Smartmontools to monitor your disks for signs of problems. I have replaced two disks at home before they went bad with the help of this.

There is a Linux Journal article on smartmontools to get you started.
