The original hsf ais very bad and it creates problems with the mobo temp as the heatsink is very small and fan just cant send enough air to cool the chip so as I said go in for a new heatsink either from asus or thermaltake. Both are good.
If you have the older style heatsink fan, and are experiencing high temps you COULD call up asus and [ehem] tell them that your chipset fan has failed.
It is a well known problem with this board, and asus will immediately send you the replacement chipset fan/heatsink. But ONLY if yours has failed. Mine actually DID fail on me, and was immediately replaced with the newer, stronger type.
You can tell if yours is the older type by the way it is mounted on the board. If it is mounted at right angles to the motherboard, you have the older type. The newer ones are mounted diagnally to the motherboard, so they are a diamond shape.
Am I encouraging lies? Perhaps. Will I burn for it? Time will tell :wink:
With my new chipset fan, my system temp is idle 35-40c 5000rpm.
