I/O Controller Hub Overheating?

Hi All:
I recently bought an "open box" Intel DG965WH motherboard for an inexpensive pc build to try out Vista O.S. The Intel Desktop Utilities is showing a temperature on the I/O Controller Hub of 80-82C. I have the same motherboard in my main home theater pc and the ICH runs 10 degrees cooler. The temperature reading is in the upper limits of optimal temperatures. Both cases have good ventilation and all other motherboard component temperatures are very good. Do I have a problem with the passive cooling on the ICH on the Vista pc? It never goes above 82C but always reaches that level within a few minutes of operation. Could the difference be due to the Vista operating system vs XP MCE2005 O.S. Anyone have some thoughts about this?

Newnerd,
How are ya? I dont know if you will see this but, i see that there are no replies to your post and i was wondering if you ever found an answer to your problem, with the overheating? Because i have the same mobo and i am having the same overheating problem. If you or anyone else could help it would be much appreciated.
Thanks,

I too am having the same issues with the same MOBO. Been pulling my hair trying to decide if it is graphics card or I/O controller hub temps causing my computer to shut down during game play. Mostly only happens while playing Everquest, but seems decent with some lag during World of Warcraft. Any insight? any ideas? any input? I am to the point of modifying my case to add yet another fan. I currently have a rear chassis fan, front fan, processor fan, 2 built in power supply fans, and a fan on the graphics card fan.

I have had an overheating problem for over 2 years, I built my computer and only have successfully used it 5 times with out it restarting on me. I have narrowed it down to the MOBO. My ICH idles at 72C and when the computer is doing anything apart from just being on It overheats and restarts. I wouldn't recommend adding fans. I had 3 fans starting in my computer and gradually moved up to 8. It didn't help at all! For those with this same board, same problem I recommend getting a new motherboard.

I had same problem. ICH was 80+ degree. I had small cpu fan in my very old PC (not in use). I put that fan on ICH heatsink and now ICH is 66 degree :)
