-- GlobalWin SAK38 Cooler

We haven't heard much from the heatsink folks at
GlobalWin around here lately. So I was quite excited when this
new item arrived on my front stoop. GW has been quietly
working on some newer coolers and venturing in the aluminum case
scene.
The first huge heatsink I purchased was actually
from GlobalWin, their FDP32 a few years back. This was for my C366
and come to think of it, it was probably overkill for that
chip. Anyway, fast forward and we're up to today where
aluminum and copper are machined perfectly for the best cooling
possible.
GW's next cooler to emerge that combines these two
materials is the SAK38. That's right, the SAK! And you
thought the CAK was a funny name, dig the SAK. Anyway, the
first impression of the unit is that it is a bit taller than most
units. Coming in
at about 70mm in total height with the fan on, small case users
beware! Check your power supply position, do not waste your
money to buy this and not have it fit!
Here are some quickie specs:
- Fan Speed: 7000±15 % RPM, 38.4±15 % CFM, 46.7±2 Dba
- Dimension: 60 x 60 x 45 mm
- Material: Aluminum Alloy with Copper insert
- Total Weight: 280g
- Supports AMD TB/XP and PIII S370s up to 1.8Ghz
This fan is not exactly the quietest, so brace
yourself. I believe its a re-labeled Delta fan, the one we all
love and hate.
One of the newer additions to the design
of the SAK38, is the new 3 hole clip. This clip is a lot better
for stabilizing the heatsink on top of your CPU. Also, if you
happen to have broken off the middle tab on your socket (Kile!), this
can be a nice alternative. It will still allow you to have a heatsink
to be used on your
motherboard. One downside of this clip is that it gets stuck in
between the fins a bit too much. It probably would be easier to maneuver
if the fins were a bit wider apart or if the clips were
thinner.
The fins of the unit have this uneven
pattern, one row is never aligned with the next. Not exactly
sure if this helps much in cooling, but it probably was easier to
machine the unit
On the base of the unit, you can see the
forged copper insert in the middle of the aluminum heatsink.
Kind of reminds of the way the Alpha heatsinks look underneath, but
that may just be me. The paper covers the TIM (thermal interface
material), which we happily removed with a credit card. The
bottom is smooth without much roughness or uneven spots. The
picture above doesn't show much shine to it, but it is as smooth as it
can be without us lapping it.
I noticed that the fan is lifted above
the heatsink with these grommets. I would assume with these
lifting the fan, some air would leak out from the sides. This
does cushion the unit from vibration of the fan, thus lowering the
sound level a bit. But, after a bit of testing it still sounds
loud and it still cools pretty well, go figure.
Our trusty old test rig is as follows:
-
IWill KK266 Socket A Motherboard
-
AMD Thunderbird 800Mhz CPU
-
Crucial PC133 CL2 Ram, 128MB
The test will consist of an idle
temperature check and a full load temperature check. The full
load will be accomplished by using the RC5
program and running 3DMark
2001 for 30 minutes. Arctic Silver II Thermal Paste used
without a doubt.

Very nice, one of the better units we've
come across in our testing rig. Some of the temperatures
achieved are the lowest we hit overall. With a kick ass
aluminum/copper combination and a great clip design, this is one you
should keep in mind when diving in for a good performing cooler.
They also include a GW case badge to boot!
Thanks to GW
USA for sending over this sample, expect to see even more from
them in the near future.
Pros:
- Great performer
- Easy to install, great clip design
- 7000rpm fan is not as loud as my older 6800 screamer
Cons:
- Clip is too tight between the fins
