If the intel fan bothers you, the CNPS7000 won't be much better. A minor
drop from 42 to 41db.

Ron,

I had it working for, my PC that is, 6 hours non-stop last night and the
ZM-50HP eventually got warm to touch on the front. I think, to be frank,
that my Geforce 4460MX card does not generate that much heat. Zalman
themselves describe it as a low-heat card.

(I personally think anyone who has the P4P800 and who hates noise with VGA
cards would have to now only buy VGA cards with built-in heatsinks and not
fans as there is no way the bigger Zalman VGA heatsinks will fit.)

Yes, it is all fitted correctly with the heatpipe on the right way, at the
right angle, etc.

With hindsight, yes, it is quieter. I suppose I was expecting 'instant
peace' but the fan on that VGA card used to drive me nuts on my last PC.
If
I had installed it along with the Zalman CPU cooler at the same time I
probably would have been posting about how wonderfully silent my PC has
gone.

The VGA heatsink has made a difference as, prior to installing it, if I
momentarilly stopped my CPU fan I still could hear an awful lot of noise
and
could not tell whether it was the VGA fan, the case fan or the PSU fan.
After installing the VGA heatsink I, late last night, momentarilly stopped
my CPU fan and, voila, there was silence! I was amazed.

So, the next thing now is to get one of those Zalman CPU 7000-alcu
coolers.

Hi,

I purchased a Zalman ZM-50HP VGA Heatsink - the smallest of the
family -
today to replace the fan on my Video card - a Geforce 4460MX. I was
lucky
and got it half-price.

The install was pretty straight forward but, upon installing the card
back
into its slot, the Northbridge heatsink was in the way.

I managed to overcome it by removing the two brass risers on the rear
heatsink of the ZM-50HP and it just squeezes in there now but I think
both
heatsinks are in contact with one another. Also, the ZM-50HP rear
heatsink
is incredibly close to the circuit board of the video card.

I've had it running for 5 minutes and the rear of the ZM-50HP is cool
to
touch as is the Northbridge. The front of the ZM-50HP, where the fan
was,
is
warm though but not even hot water bottle warm if you know what I mean.

I wonder if I could get away with simply removing the rear heatsink
altogether and just have the pipe running around the back?

Wow. I wouldn't do that. The coolant in the heatpipe has to be
condensed back into a liquid state at the rear heatsink before it can
be wicked back to the front heatsink. Regardless of the perceived
temperatures of the two sinks, I wouldn't interfere with the way the
cooler works. Also, if the sinks aren't really that warm, then maybe
you didn't get a good connection between the card's GPU and the front
sink. I don't have one of these coolers but reviewers have described
the rear heatsink as being very warm, indeed. If you're rear heatsink
is actually "cool to touch," then it suggests a problem in
installation or a manufacturing defect. You do have the pipe
installed so that the front is lower than the rear, don't you?

I don't think any other of the Zalman ZM VGA heatsinks - I saw them in
the
shop and they dwarfed the ZM-50HP - are going to stand a chance of
fitting
in the P4P800.
The Zalman tech on their board at www.zalman.com.kr has stated several
times that the ZM-80aHP does, in fact, fit on P4P800s and P4C800s, but
it fits differently from the older ZM-80HP. Is it possible that you
saw the older version?

Oh, is my PC noticeably quieter? No, not really. The VGA fan used to be
noisy in my last PC but I think it had been drowned out by the Intel
fan
in
the P4P800.
Yes. It's not worth investing in one of these fanless coolers unless
the louder noise problems on your PC have already been solved.

Comments/thoughts welcome.
