Hi,
I have an intel P4 3.2 GHz lga 775 [640 model] installed into a ASUS
P5AD2-E Premium board with the standard intel cooler. I had tried
installing the Zalman 7700CU but found it came about 0.5 inches over
the edge of the board, and so would not fit in my Lian Li v1100 quiet
case. Can anyone recommend quiet cpu cooling units that would work with
the p5ad2-e premium? I was considering the thermaltake xp-120 with the
panflo 120 fan.
Thanks,
George

If you have zero clearance between the top edge of the motherboard
and the PSU, either get a larger computer case, or a smaller
HSF. I think it is likely, a XP-120, a Zalman 7700, and a
Zalman 7000 (with LGA775 adapter ring) would all overhang the
top edge of the board to some extent.
The XP-90 is a bit smaller than the XP-120:

When paired with a Panaflo 92mm L1A blowing downwards, the
thermal resistance is ~0.20C/W.
You can compare to the XP-120, to see how much of a difference
that overhang is making. Not that much difference.

A thermal resistance of 0.20C/W means, if the processor kicks out
100 watts, the processor case will be 20 degrees C warmer than
the case air. If room temp is 22C, case air temp is 29C (7C air
temp rise in case recommended range), then the processor case
will be at 49C. You can look up "TDP" in the datasheet for your
processor, to get an exact power number.

I wonder what the "customized adapter kit" is, listed in that FAQ ?
Maybe purchasing these two items is all you need.
LGA775-RM adapter kit $8
http://www.newegg.com/app/viewProductDesc.asp?description=35-999-351&depa=0
XP-90 $43
http://www.newegg.com/app/ViewProductDesc.asp?description=35-109-119&depa=0
There is also a XP-90C all copper unit for slightly more. The weight
of the all copper version will be more than the XP-90.
The Panaflo FBL09A12H1BX on this page has a tachometer output. The fan
comes with no cable on it, so you'll need to find a cable. At the
bottom of the page, are components to make a cable. The "H1" means this
is a higher speed fan (i.e. it is not an L1A), so you'll also need a
rheostat to drop the speed.
The fan with tacho output is here ($9.25)

A ready made cable assembly is here. Note that it is likely that all
the Panaflo fans on this page have no tacho output, so you are only
getting a 2907CGWA cable for $1.49 .

The Fanmate2 can be used to drop the fan speed ($7). It should fit
with the 3 pin 2907CGWA cable.

So, $70 plus lots of shipping, to do the job. Or, you could make the
cable yourself, using the Digikey parts at the bottom of 1364.pdf,
if you can figure out exactly what to order. Then, you only have
two orders - one for Digikey and one for Newegg.
I do hope there is a better fan available than the Panaflo. A ready made
92mm solution with tacho output would be much less hassle, but locating
good fans is not easy.
Have fun,
Paul
