Skiving technology process - Step 1

Skiving technology process - Step 2

The Skiving process is still relatively new to the heatsink market and produces a high surface area heatsink with a
simple method and low cost production. This process provides an advantage that the fins are cut into the base on an
angle, and then bent upwards. This means there is no bonding material between the base and fins and the process can
produce more fins for cooling.

Searching the web did not yield any visuals or documents to explain the process, so here is my interpretation. The
process involves taking a solid object, in this case, clay, and cutting down on a slight angle. The cut fin is then
angled so the newly created fin stands. In the case of heatsinks, there is a lot more fins cut at once, than what I
demonstrated, but this does show the basics involved in the skiving process.

The installation was very straightforward. The supplied generic thermal compound is meant to be used, but do try to
get some reputable compounds when possible. Place the JAC663a onto the CPU and using the supplied retention clips,
hook one end onto the retention module base. By pushing down on the thumb pad, you should be able to secure the clips
with minimum fuss. Plug the three-pin connector into a spare motherboard header and you are good to go. I decided for
testing purposes to test the JAC663A against the stock cooler in my Pentium 4 system. The current system is Pentium 1.6a
using an Asus P4B motherboard. After previous Arkua 8568 HSF Cooler
testing, the thermal pad was warn down. For this series, I cleaned the bottom of it and applied Arctic Silver 3 thermal
compound as specified by the Arctic Silver website. Temperature monitoring will be supplied by Motherboard Monitor
5.1.0.7 and recorded at idle and under load. I will be using SiSoftware Sandra Burn-in Utility to put the CPU under
load for ten cycles at normal priority. I also overclocked the processor to 2.1 gig and repeated performance tests in
overclocked mode.

Conclusion:
The CoolJag JAC663A Cooler is an average and not high performance cooler, since the test results were very close comparing
the unit to a stock P4 Cooler. In idle, load and overclocked modes, I managed to shave off one degree compared to the
temperatures set by the stock cooler. In the defense of the JAC663A, the thermal tape that was supplied with the stock
P4 cooler was removed and high performance Artic Silver 3 was used in its place. However, even with the substitution,
I had hoped that the JAC663A would fair much better than what the tests demonstrate. Overall, I’m giving this product
a rating of 7 out of 10 and would only would recommend this
product those individuals who wish to upgrade their current stock cooling system. If you are into overclocking, my best
recommendation is to purchase a cooler with a copper heatsink base for better overall performance cooling. If you have
any questions regarding this review be sure to visit the CoolJag
