Zalman Coolers
Posted by Jamie on July 20th, 2005


I was wondering if anybody has any Experience with Zalman coolers, I have
heard nothing but good about them. I have a Vantec AeroFlow installed now
and I am less then impressed with it. I was wondering if anybody had a
recommendation on a Socket A(462) HSF from them. The following are the ones
that I have looked at. Thanks in advance

ZALMAN CNPS3100-PLUS CPU COOLER S370/S462
ZALMAN CNPS6000-PLUS CPU COOLER S462
ZALMAN CNPS7000B-CU CPU COOLER S478/754/939/462

I have an Athlon XP 2500 and I use the Zalman CNPS6000-ALCU. I have
undervolted the processor by a little and I use CPUIdle and for
non-intensive tasks, the heatsink cools the CPU without a fan. I do however
use the large fan that came in the kit, I was just pointing out how good the
flower cooler is. With the big fan running slowly, you can hardly hear it
and with it turned to max, it is still pretty quiet.

GT, how big is the fan that comes with the kit? It looks like it could be an
80mm if that is the case that HS is going to be huge did you have any
trouble mounting it in your case? The Heatsink I mean.

This is the one I was talking about not the 7700, that is a beast. Does
anybody have any experience with this one?

The 7000-Cu was mounted on an Asus P4P800 (socket 478), with a Northwood 2.8
oc'ed at 3.4 GHz, as replacement of the stock unit (not enough cooling) and
it's later replacement ThermalTake Spark 7 (too noisy). The 7000 was very
easy to mount and is really quiet. It not only decreased the CPU temp with
4°C (compared with the ThermalTake), but also the motherboard temp, thanks
to the Zalman radial flow. Temps at hidh usage (video rendering) are only
38°C for CPU and 34°C for motherboard (data from Asus Probe, at ambient temp
of 22°C).
The Zalman 7700-Cu was used on an Asus P5P800-S, with Prescott 3.0 Ghz, not
oc'ed. Idle temps with Intel stock cooler were 44 °C for the cpu and 36 °C
for the mobo (ambient temp was 24°C). The fan was always spinning at more
than 4500 rpm and the noise was horrible (wonder what Intel will do about
this problem !!!). Based on my previous experience, I replaced again the
cooler with a Zalman model. Only the 7700 is suitable for socket 775 and I
was afraid of its heavy size. Indeed, the cooler did not fit in the
CoolerMaster case due to the proximity of the PSU. The motherboard had also
to be dismounted in order to fix the cooler counterplate under the board. In
fact, there was no real problem, just some worktime. I had to fold 4 fins a
little in order to gain 5 mm and fit the large cooler near the PSU. Again,
compared with the stock cooler, I was surprised by the very low level of
noise, even at full speed, which is only 1500 rpm. The temp at idle was 4°C
lower than wih Intel's cooler, which is generally considered to do a good
cooling job.
The only problem I encountered was a boot error message (CPU fan error !),
probably because the bios is not set for cpu fans at such low speeds (stock
Intel is 2500 rpm minimum). This did not prevent me to boot however and for
my customer' peace of mind, I disabled the cpu temp detection in the bios.
I've seen that there is now a bios update available to solve this minor
issue.
My conclusion: maybe Zalman are not the best aircoolers of the market as far
as cooling is concerned (there are some better heatpipe models), but they
are the king if you consider the mix of the price-performance-noise
parameters.

My son uses a 7700 on his 3.2 GHz P4 Prescott without the controller
and he has had no problems.

can read further. If you mean the manual speed controller, removing it did
not change anything, even set at full speed, which is still only 1500 rpm.
I believe it depends of the bios settings and where the manufacturer has set
the minimal rpm's to display an alarm.

I have the cooler attached to my tower case (so it is vertical). The
heatsink attached no problem and it just clamps in place as all other
heatsinks do - There is no chance of it the heatsink going anywhere! You
have to be careful as the heatsink is quite wide and can be close to the
power supply if your socket A is close to the edge of the board. I have the
Soltek SL75-DRV5, so if you can find a picture of that on the web, then you
will see how much space there is from the socket to the edge of the board
and compare it with your own. It does not weigh anything near a kilo - way
less than half that I would say. The fan is a 120mm and the speed controller
allows it to go from silent and to really quiet - the controller is designed
to be inside the case, but I poked the wires through a little hole in the
back of the case and left the controller on the rear for hot days + heavy
gaming!. The fan is mounted on a curved metal arm that screws into the
screws where the PCI cards plug in. The arm can be used to attach further
fans if required - to cool PCI card or graphics cards.

There will be a setting in your BIOS to warn of low CPU fan speed you can
either adjust the warning threshold level or turn off the warning
altogether. My fan normally runs around 1250, so I made the warning 1000
rpm.

I have just realised you are talking about a different cooler - we were
talking about the CNPS6000-ALCU, not the round 7700Cu.

Some PCs have CPU fan warnings built into the motherboard's BIOS. It is this
setting we are talking about lowering or disabling. Using MBM5 gives you
software access to the BIOS readings, so can give you an extra level of
detection and warning, However PCs that have BIOS support for fan speeds and
processor temperature (the majority do) will also include warning beeps
followed by emergency shutdown in case of overheating.

GT, here is the one I am talking about. If that is a 120mm fan looks like I
will have to by a server case just for the heatsikn lol. Please tell me
this is a 80mm Fan lol.

Indeed. I run both the BIOS alert and MBM5.

I think my son is doing the same.

The advantage of MBM5 is you can monitor things during actual
operating conditions. When you are in the BIOS. the system runs faster
than idle for some reason. My CPU jumps from 36C idle to 40C when I
access the BIOS. It also runs that way when I reboot.

Here are the coolers that I am considering, the 6000 is what I am thinking
on getting unless you guys have anything else to say about the others. Just
to avoid confusion avalon software is here in Newfoundland, Canada so it is
Canadian dollars but I will be ordering online as I hate those moronic
assholes at avalon.

http://www.avalonsoftware.com/viewproduct.asp?pid=2553 3100-PLUS

http://www.avalonsoftware.com/viewproduct.asp?pid=2554 CNPS6000-PLUS

Both of those seem to be the same except for the fan controller and the
bracket to house additional fans. The other Zalman models I found are noice
but they look a lot bigger. I believe they are the 700's and 7000's. I am
assuming the 7000 is what you guys were saying has the 120mm fan?

You are quite correct, the fan is 80mm - I just took my case off and
checked. I thought it was 120mm, but it is 80. The heatsink is actually
barely wider than the fan - that photo doesn't quite show the perspective
properly (or the heatsink has got bigger since I bought mine). I have the
half-Cu half Al version of the 6000, so mine will be lighter than the all
copper affair, but it is the same design, only mine won't cool as well as
that one - my CPU is currently wobbling around 38 degrees.

Just make sure there is enough clearance between your CPU socket and the
underside of your power supply - mine practically touch. You need a few
cms - difficult to judge because the heatsink obscures everything, but
perhaps 4cm gap?

The bios temp is a true idle temp. Inside a modern OS, the
lowest priority level is an ACPI HALT idling command that
causes even lower power usage. However, it does so at the
cost of a few clock ticks, slight performance loss that
isn't important for most uses but in some cases (like video
capturing/realtime-compression) can become significant.

A large externally mounted fan does offer potential for
quiet operation but no quieter and poorer performance than
one of a few Thermaltakes, either their solid copper or the
rasied design with the heatpipes (model #s escape me at the

issue with the Zalmans is the lower quality fan, though it's
no big deal to replace IF you get the bracketed/flower type
'sink as it is a standard fan, unlike the one on the
CNPS7000B-CU.
