The nVidia 680i motherboard reference design has a moderately large (40 mm X
50 mm X 30 mm fin pack) heatsink and 50 mm 5000 rpm fan on the Nortbridge,
connected by a heatpipe to a heatsink on the Southbridge.
The ThermalTake i1 (~ $30 US) arrangement is a nice fit in that its airflow
does not interact with the airflow of the fin pack/fan on the nVidia 680i
reference design Northbridge heatsink/fan. The ThermalTake i1 airflow is
parallel to the surface of the
motherboard, directed from the internal connecter (front) side of the
motherboard toward the external connector (rear) side of the motherboard.
The Northbridge air flow is parallel to the motherboard directed from the
CPU end of the motherboard twoard the adapter slot end. The ThermalTake i1
fin pack is almost entirely further from the motherboard than the
Northbridge fin pack. I think this is probably the best possible
arrangement for air cooling when using a Core 2 CPU with a high speed FSB.
With my E4300 / EVGA 680i I've had no trouble using a 1333 MHz FSB
(multiplier X8) with the above air cooling arrangement. Had I the chance to
do it over, I might chose the ASUS 680i motherboard over the EVGA
motherboard but only because of the possibility that the ASUS
temperature/fan speed/voltage monitor program might give more results than
nVidia nTune and NVMonitor. (I originally passed over the ASUS because I
could not download the motherboard manual from the ASUS web site - but since
that time (March) I have been able to download that manual.)

| Good point. I may give it a go.
