Scythe Kamakaze Heatsink Review

Former staff writer    -   January 4, 2004


Installation
While a little tricky at first: until I figured out to put light pressure on the retention clip. I was then able to gently snap the retention brackets to the Ziff’s cleats. The instructions where very vague but they did mention not to over tighten the retention mechanism as it would cause damaged to the heat sinks retention screws. I feel that there is more of a chance to crush or kill your CPU applying to much pressure while tightening the retention screws. Extreme care must be taken installing this heat sink as to not damage your CPU.


Testing
Testing Method
Temperatures for the testing were taken via a CompU Nurse thermal probe located next to the CPU die. Artic Silver 5 (thermal compound) was applied to the cpu and each heat sink according to the directions located on Arctic Silver's web site. The compound was given 72 hours of use before the testing was done on any of the heat sinks. To achieve the "idle temperature" reading, the computer was allowed to set idle for 15 minutes then the reading was taken. To achieve the "load temperature" Prime95 was run for 15 minutes and then the reading was taken. The overclocked temps were taken in the same manner only the fsb was changed to 200 and the Cpu voltage to 1.70v. This is giving us a 366 MHz over clock. All fans were tested at the full and slowest speeds. Also the fan for the Kamakaze was turned upside down sucking air up thru the heat sink. I was getting temps 4c higher over the aero7+ with the fan blowing down.

Testing Setup
  • AMD Athlon XP 2500+ 11x166 / overclocked to 2800+ 12.5x166
  • ASUS A7N8X-DLX Rev 2.0 (nforce2 ultra chipset)
  • 1x512 Hyperx pc3500 cas2 2-2-11
  • Chieftec Dragon case, 5 80x80x25mm Antec fans 7volt mod
  • Artic Silver 5 thermal compound
  • Running windows XP pro service pack 1

    Testing Results

    The fan speeds varies greatly. Scythes fan has more rpm, but use’s a traditional axial fan. Aero7+ on the other hand uses a squirrel type cage blower fan: this helps to eliminate the dead spot caused by axial fans.

     

    We can see here that all the fans a pretty close in noise level. While the Kamakaze has them all beat in its lowest setting. The aero7+ does seem to be louder than the Kamakaze at full speed.

     

    We can see here that the Kamakaze really shines at stock speeds, leading the aero7+ by 4.9c load and 5.4c idle. The low fan speed temps are very nice besting the aero7+ by 9.9c load and 9.2c. I was amazed at the temps gotten with the fan set to low.
