Scythe Ninja Plus takes on Three TEC Heavyweights

Test Results

Overclocking And Heat

The Pentium Extreme Edition 955 has great overclocking potential as long as it's kept cool. Testing revealed that the processor would crash consistently at 79 degrees Celsius, so every attempt was made to increase clock speed within that temperature threshold.

The highest processor speed and voltage at which the Scythe Ninja Plus Revision B could stay within the EE955's heat-stability limit was 4.12 GHz at 1.30V. Raising the core voltage to 1.45 V allowed all the TEC coolers to support the CPU at 4.33 GHz. Any further increase in clock speed required another increase in CPU core voltage, resulting in an eventual system crash as temperatures exceeded the 79°C level.

At 4.12 GHz, the Ninja Plus Rev. B is already reaching this processor's maximum stable temperature, while the TEC coolers have a little more room to play.

At 4.33 GHz, the TEC coolers reach their limits, and the Ninja Plus Rev. B is past its capabilities. Even though the Titan Amanda uses two fans while the Monsoon II Lite and Ultra ChillTec each have only one, the single fan of the later two coolers seems to be more effective. Even so, any further increase in core voltage pushed heat levels beyond the capabilities of all three TEC coolers.

  • Ninja Plus is Junk. My origin cooler with dual 120mm fans, one front and one back create perfect air flow, temperature from 39C to 50C max. After installed Ninja Plus along dual fans remain place, temperature only 1C lower to as high as 51C. Blow my brain is, peoplee hype up gimmick without even test the dual 120mm fans in the box 1st then jump into conclusion Ninja excellency. Wasted my $ and time due to the unproven text result with flaws. I saying this because I even tested in socket 478 old pc, same thing with dual fans flow in case. In conclusion Ninja is ajavascript:%20void(0); piece of junk other than try sell hype..
