If you want a 925XE motherboard, avoid ASUS like the plague. Get an ABIT, GIGABYTE or FOXCONN in that order. ASUS got the features but their product s don't live up to the features.
So, for the heat-sink/fan the way to go is with a Zalman pure copper and Artic Silver 5 (properly installed)
, why? because I've red many testimonials where the heat-sink/fan and AS5 shaves off between 15 to 20 degrees. I never thought that copper would good for heat-dissapation but after owning two Northwood core processors Socket 478, I see my 3.2GHZ running at 28C idle using a combination of aluminum fins and copper base heat-sink and my 3.0GHZ runs at 34C with an all-aluminum heat-sink. Both RETAIL version Processors.
ZALMAN Copper CPU Cooler for Socket 775 Model "CNPS7700-CU"
This right here is a great choice for an LGA 775 MoBo: ABIT "AG8-3rd Eye" 915P Chipset Motherboard for Intel LGA775 CPU - Retail
, it takes the less expensive DDR and same features as the 925XE (except no DDR2). I'm not too impressed with the performance of DDR2, so 915P Express it is my next build. Crap, it was on Stock 5 min. ago. well Autonotify it is or buy somewhere else.
But remember, avoid ASUS like the plague at all cost.
