The packaging:
The notebook
cooler is packaged in a colorful retail type package. The back of the package
contains the specs as seen above. Contrary to the specifications, however, the
fans only receive 5V from the USB port. (It is possible that they meant the fans
are 6 volt fans, but they run off the USB at 5 volts. Hence, lower noise as
noted in the Pros section). Moving on...

There it is:
The cooler is
easily unfolded by pulling the legs in opposite directions. Once the legs are
pulled out as far as possible, you twist the center part (the fans) to face
upward like in picture 4. Note that the USB cable wraps around the center piece,
so it isn't floating around in travel. I didn't measure the USB cable length
from the unit, but moving it around both sides of the laptop and thinking about
all of the laptops I have seen in recent years, the wire should reach any USB
port just fine.

A closer
look/installed:
In pictures 3-5
you can see that there are 4 rubber feet that hold the laptop and your cooler in
place. They work well with my particular laptop. It is not pictured, but the
aforementioned hookup for power to the USB hub is in the front of the cooling
unit. The best place for an adapter to power the USB hub is a good electronics
supply store that can provide you with a universal/multi-voltage power adapter,
such as
Radio Shack.

Since this
particular laptop only has one USB port, this cooler / hub is a life saver. Any
Plug and Play OS should find the USB hub and install it without incident. I
believe this would include Macs as well.

Battery drain:
One thing that
you may be worried about with the addition of the X Notebook Cooler is
accelerated battery drain. While this product is meant for your laptop when it
is in a workstation environment, I wondered what effect two 60mm fans
circulating air under the laptop would have on battery life. To summarize the
pictures: picture 9 was taken with the AC power unplugged; picture 10 with the
fans on after 10 minutes; picture 11 with the fans off, ten minutes later.
| Time: Fan on or off |
Battery remaining % |
Battery time left |
| 10:24 (on) initial timing |
54% |
1:43 hours |
| 10:34 (on) at 10:24 |
47% |
1:30 hours |
| 10:44 (off) at 10:34 |
38% |
1:12 hours |
So if you
understand the above chart, having the fans on, the battery did not drop as
much. 54%-47% is 7% difference. There is a 9% difference when the fans are off.
I'll have to attribute that to the fact that this laptop is 4 years old, and the
battery is funky when it gets to a lower power mode. No, I didn't get the tests
backwards either. If anything, you can say that this test is inconclusive, and
who is going to put this cooler under a laptop without the laptop being plugged
in anyway? I was just curious as to if it was a large drop in draw with the fans
working. Even though the testing was inconclusive, I'd say that the fans being
on or off makes little difference on battery consumption with the laptop on
battery power.

Does it work?: (A
sort of Q & A with, well, myself...How odd...)
I threw the
following thoughts around in my head and came to the following conclusions...
Lower
temperatures? Most likely; I'd guess a degree or two Celsius perhaps.
How can you
measure it accurately? I could have rigged a thermal probe with the laptop,
but if it was on the bottom, the fans would cause the temperatures to drop
because of the direct airflow. It's almost a moot point because plastic doesn't
conduct heat very well.
In what
direction do the fans blow? The fans actually blow downwards. I personally
think they should blow upwards. That is logical to me, but in all fairness,
airflow is airflow. If you want the fans to blow upwards, get out your drill.
You'll need to modify the fan holes on the fans to flip them around.
[Editor's note:
I recall reading a wise quote about fan and heatsink debates on the [H]ardForums
sometime in the past. It went something along the lines of "When you want to
cool down your soup, you don't try to suck the air away from it; you blow on
it."]
Will the
laptop be more comfortable to type on? Yes. A laptop has a flat feel to it.
With smaller keys, you can (and will) get used to it, but giving it an angle is
surely going to make it more comfortable.
So is it
going to help? Yes. You are getting a more comfortable angle to type on, and
peace of mind that your laptop has airflow around it. I've seen many desktop
systems in my days with funky exhaust fans to cool a processor with a huge
passive heatsink. It works passably, but I'll take real airflow any day to
airflow that is done unconventionally.
Will it
extend my battery life? Well, as seen in the testing section above, it
didn't hurt. I don't have a clear answer to that one.
How does it
sound? Not bad. Yes, you can tell it is on. Folks with P4 laptops (not
Celeron P4 laptops) are already used to some fan noise. You'll get used to it.
It is no louder than a quiet desktop of current days.
Summary:
I've thrown
quite a few things at the hub. Laptop USB ports sometimes don't put out the full
500ma that are needed for some devices. I have thrown an HP 840C printer, a
generic USB mouse, a Kodak digital camera, and even a FlexiGlow Fx Game pad at
it all at once. Not a single issue, even with the two 60mm fans running. Your
results maybe different, but this Acer 732tx notebook runs fine being plugged
into an AC source during heavy testing as seen above.
Pros:
-
It doesn't seem to
be 30.26 dBA. It seems more like 27 or so. You'll notice it is on, but it
isn't bad at all.
-
Should increase
notebook life.
-
Adds an angle to
the laptop making it more comfortable to type on.
-
Adds 4 USB ports!
-
On/Off switch for
fans.
-
It should give you
some peace of mind.
-
Portable.
-
Very light.
Cons:
-
It is made of
plastic. It feels somewhat flimsy. (My big beef with the product. But in
defense, the weight of this laptop holds the stand in place.)
-
Very light laptops
may have an issue with moving while typing. (I'm talking about Centrino
notebooks mostly, although this is just a guess)

Closing:
I'd like to
thank
COOLMAX for sponsoring this product for review. Also, if you want to know where to buy one of
these, or other
COOLMAX products, head on over
here. Be sure to hit their
homepage as well. They have lots of neat stuff. I hope you enjoyed the
review. Until next time...
Update: (4/11/05)
Yes, you have noticed I did not do temperature testing. Taping a
sensor to the bottom of plastic is no way to test/take temperatures. I have found out
a way to test internal temps on a laptop, but I won't do an addendum unless
someone wants me to. And, as of 4/11/05 the NB-801 is discontinued. The
replacement is the NB-802. The changes being that the hub is now USB 2.0
compatible. :)
