Here you see the completely copper base which has two U-shaped heatpipes running through it. These heatpipes are the only thing connecting the base to the heatsink, as there is no direct contact between the two.
This is the mounting system used for the Socket 478 processor we will be using. Looks like a pain in the bum to install compared to the ease of the stock cooler.
I was quite impressed with the smoothness of the copper base on this CPU. It was covered with a protective layer of plastic to protect against any scratches that can happen during shipping. Not a single scratch, and shiny as a new car.
The fan on this bad boy is a 92mm based fan, which emits an estimated sound level of 25.0dba at 2000 RPM. The fan connects to the heatsink with two almost invisible metal clips that run along the length of the aluminum fins.
The Scythe Katana has 40 aluminum fins, with a nice wavy design. Inside the heatpipes are soldered directly to the fins, in a spread out fashion so to allow better airflow.
The Scythe Katana will be compared to this, a very powerful stock Intel cooling solution. As I said before, the only thing this stock fan has trouble with is being quiet, other than that it has worked amazingly in its time of use.
This is our test bed for the CPU cooler competition of today. It is a standard 2.4Ghz Intel Pentium 4 system on an Asus motherboard. It is a cooler CPU, but you can never be too cool when it comes to a processor these days. This is a simple workhorse computer with a fancy case, nothing out of the ordinary for a home workstation inside.
These are the testing parameters:
• Intel Pentium 4 2.4Ghz 533Mhz Processor
• Asus P4B533 Motherboard
• Cooler Master HTK-002 (fresh application for each test)
• Ambient Room Temp: 27 degrees celcius
• Idle time calculated after 1 Hour of no use after bootup
• Load time calculated after 1 Hour of CPU-Burn In
• BIOS Smart FAN settings disabled so full speed is always on.
As you can see by the chart, the Scythe Katana was beaten by the stock Intel cooler. It still performed quite well, but the stock cooler won the challenge as it was designed specifically for the CPU instead of a universal choice.
As a side note, the Katana did win hands down in the sound department, as even at 2000 RPM it was noticeably quieter than the stock cooler. So for those willing to sacrifice a degree or two for a quieter system, this CPU cooler is for you.
