Re: Super Hot Southbridge
what mobo and what size fan?
Re: Super Hot Southbridge
I wish I had a picture, but a custom system I built last year had a similar issue. I ended up using some non-conductive plastic (the stuff SuperMicro and other companies use for directing airflow in their chassis) and built a small tunnel like device that directed some of the airflow from the cpu fan over the southbridge HS. Even though that air was normally warm, it kept the temperature of the SB HS down.

Even after replacing the fan the temp stays at like . . . 80C. It's crazy but the computer hasn't exploded yet. The fan kinda sucks because it is loud and small and this is supposed to be a HTPC. I think I'll try and remove the heat sinks and re-seat them with some IC diamond, and then I think I might try modding that little fan shroud and put a new fan in there. For now, the computer is running and I don't think it's going to die. It's always run really hot (this computer is over 4 years old now) and I've never had any real issues.
I would probably have ignored it, but last night I was trying to install windows and was having issues. As soon as I got everything fanned up again, things worked. Oh well. I'll post pics and a video later when it's all set up.
Re: Super Hot Southbridge
A couple of years ago, my sister's computer would crash during boot just as the Windows GUI would load up. I noticed that the nvidia southbridge was hot enough to fry an egg on. As soon as I swapped out the heatsink for a larger one with a better fan, the machine did not have any further issues.
If there are proper mounting holes or retention clips for the SB chip, you should see if you can get a sink with larger fins. The stock sink probably was never capable of dispersing that much heat.
Re: Super Hot Southbridge
I had a friend who's computer kept locking up. Her (deceased) husband had hacked together a way to hold the cooler onto the south bridge with a couple pieces of aluminum angle screwed inside the case. It eventually fell off. Turns out the original problem was the retention clips both came out of the mobo (bad solder job). I drilled out the holes slightly and built new mil-spec clips that will never pull out. Fixed.
