TS Heatronics NCU-1000 Pentium 4 Heatsink Review
There have been very few entirely passive heatsinks across this test bench -
perhaps only five since we began reviewing heatsinks in 1999... What really makes the TS
Heatronics NCU-1000 stand out, is that it is an
entirely passive heatsink for the Intel Pentium 4 processor (max. 2.8GHz). The
NCU-1000 (care of Scythe Co.) does not come with a fan, but nor is there any place on the heatsink to
actually attach one
should you decide to add a fan of your own. Instead,
the NCU-1000 makes use of the airflow that already exists within a
computer case to keep itself, and the processor below, cool.
A distinction which needs to be made early on
is that while this is technically a 'zero noise' heatsink - a cooler which in
and of itself produces exactly 0 dBA of noise - it cannot operate without some
degree of airflow within the computer enclosure. So whether that airflow comes
in the form of convection currents, or more likely, from the intake and exhaust
fans of a powersupply and case, the heatsink needs some degree of air moving
over its folded aluminum fins in order for it to work.
you could think of this way, while the TS Heatronics
requires no direct cooling, or noisy fan, it does indeed need the
airflow generated by them to operate within comfortable temperature levels.
For the purposes of this review, we will be
using a single 92mm x 92mm low-noise Zalman fan set at 6" and 12" distances
from the TS Heatronics NCU-1000 heatsink, to replicate typical computer case air
flow in an impingement fashion. I can tell you right now, the temperature
results we saw were not at all what we expected to see from a passive

comes unassembled, and packed rather neatly in a small box. Because of the way
the cooler is attached, you will need to remove you entire motherboard to
install this heatsink. A stainless steel backplate, insulating layer, long
screws, and several other parts are included to ensure the heatsink stays firmly
in place once installed.
The first step once all the parts are laid out is to
assemble the upper heatsink portion which consists of the thick copper base
plate, a stainless steel retention plate, and the "U" shaped heatpipe component.
If you don't take a few minutes to read the instructions,
right about here is where you can seriously muck up the entire installation
procedure. The reason is pretty simple, the copper base plate will accept the
heatpipe in one of two ways, each 90 degrees to the other. Depending on how the
Pentium 4 socket is oriented on the motherboard in your PC, the heatpipe will be
oriented in one of those two ways.
Always, the fins of the NCU-1000 heatsink must be
vertical, pointing straight up and down, in order to take advantage of the air
currents within the PC case. How the NCU-1000 actually stays cool without a fan
is what will discuss next...
