Just installed this board on a new winXP build and noticed high idle temps for ICH/MCH. Once start playing games and etc. they get into
the eighties easy. ICH is the hottest as the geforce 280 is right over it so can't stick a fan on it. Is this normal behavior on these parts of
the mobo?

The only solution I can think of is replacing the video card with a shorter one allowing ICH to get more air. Is it feasible to replace the
thermal paste on the ICH/MCH? Never looked into it. Granted this board isn't "high end" so the general layout could be at fault.

Just point the fan at the motherboard from front so air is blown along the board.

not the same board but my DG965WH has a very warm ICH, I don't know if it's normal or it's degraded with lots of leakage, overvolted or something, but it has a heatsink, and without direct airflow it goes over 80 c easily, I placed a 80mm basically on top of it and it can run around 60 like that, but it still feels pretty hot for what is supposed to be a 4W TDP chip with a heatsink on top of it and huge amounts of airflow

I guess, that's the benefit of most of my lga 775 boards not reporting ICH temp and they all run hot, I don't know.

Don't have the option of adding a fan to the side panel since it's glass but I can add one to the front. I'm gonna pick a good one too
like a BeQuiet or Noctua brand.

What are you using to check those temperatures ? Have seen many OS based apps not report some Temps correctly (some allow an adjustment for chipset type instead of just "reading it") ... just a thought

you can even bodge old power supply fan wired for 5V inside the case somewhere close to chipsets

SpeedFan and the Intel utility that came with the mobo. Heck, I even went into the bios and watched the ICH temps climb from 57 to 73 within 10 minutes.

yep the bios reports the ich temps on those boards, and my finger confirms the temp.

Intel DP35DP has a good big heatsinks on a chipset. It would be better only if heatsinks are copper pipes like overclocker's mainboards have.

Yeah I've been shopping around ebay for those, they come with a "nominal" fee unfortunately even used.
