Scythe Ninja vs Xigmatek Achilles
Today I am going to compare two heatsinks, the Scythe Ninja Plus Revision B and the Xigmatek HDT-1284 (aka Achilles) both of which use the push-pin mounting system. On each heatsink I will run OCCT for 30 minutes at stock speeds/volts and overclocked to 3.2GHz on stock volts. Also I will find the maximum stable overclocks possible whilst keeping temperatures safe. Artic Silver 5 was used through all the tests and applied following
these instructions. All temperatures are measured in degrees centigrade (°C).
All tests were run on the following system:
- Q6600 G0
- OCZ Platinum PC2-6400
- DFI UT X48-T2R
- XFX 9800GTX
- Gainward 8800GT
- OCZ StealthXStream 600W
- Antec 900 (All fans on low)
- XP SP3 x86 (26 processes running)
Scythe Ninja: 2.4GHz(266x9)
Throughout these tests the ambient temperature was 17°C.
Idle Test
After windows had booted I left it on the desktop for 5 minutes to allow the temperatures to stabilize. The temperatures for each core at this point were 28, 27, 25, 25 respectively. The voltage according to
CPU-Z was 1.328V.
Load Test
For the second test I ran OCCT on mix for 30 minutes. I measured both the maximum core temperatures and the overall core temperature average. The maximum temperatures recorded by RealTemp were 58, 58, 61, 61. The mean temperature across all 4 cores was 55°C. The voltage according to
CPU-Z was 1.28V. The
CPU took 3 minutes to return to it's original idle temperature.
Maximum Overclock
The maximum stable overclock I could achieve with this cooler was 3.2GHz. Any higher resulted in the need for more voltage, which intern caused painfully high temperatures.
Scythe Ninja: 3.2GHz (400x8)
Throughout these tests the ambient temperature was 16°C.
Idle Test
After windows had booted I left it on the desktop for 5 minutes to allow the temperatures to stabilize. The temperatures for each core at this point were 28, 27, 25, 25 respectively. The voltage according to
CPU-Z was 1.328V.
Load Test
For the second test I ran OCCT on mix for 30 minutes. I measured both the maximum core temperatures and the overall core temperature average. The maximum temperatures recorded by RealTemp were 67, 67, 69, 69. The mean temperature across all 4 cores was 64°C. The voltage according to
CPU-Z was 1.312V. The
CPU took 4 minutes to return to it's original idle temperature.
Xigmatek Achilles: 2.4GHz(266x9)
Throughout these tests the ambient temperature was 20°C.
Idle Test
After windows had booted I left it on the desktop for 5 minutes to allow the temperatures to stabilize. The temperatures for each core at this point were 27, 26, 23, 23 respectively. The voltage according to
CPU-Z was 1.328V.
Load Test
For the second test I ran OCCT on mix for 30 minutes. I measured both the maximum core temperatures and the overall core temperature average. The maximum temperatures recorded by RealTemp were 45, 45, 46, 46. The mean temperature across all 4 cores was 42°C. The voltage according to
CPU-Z was 1.312V. The
CPU took 1 minute to return to it's original idle temperature.
Xigmatek Achilles: 3.2GHz (400x8)
Throughout these tests the ambient temperature was 20°C.
Idle Test
After windows had booted I left it on the desktop for 5 minutes to allow the temperatures to stabilize. The temperatures for each core at this point were 27, 26, 23, 23 respectively. The voltage according to
CPU-Z was 1.328V.
Load Test
For the second test I ran OCCT on mix for 30 minutes. I measured both the maximum core temperatures and the overall core temperature average. The maximum temperatures recorded by RealTemp were 51, 51, 53, 53. The mean temperature across all 4 cores was 48°C. The voltage according to
CPU-Z was 1.312V. The
CPU took 1.5 minutes to return to it's original idle temperature.
Maximum Overclock
So far I managed to get 3.4GHz stable. At this speed temperatures are still below 50°C. I'm sure if I try a little harder I will be able to get to 3.6GHz without a problem.
Conclusion
As you can see from the above results, the Xigmatek Achilles greatly outperforms the Scythe Ninja by about 15°C in all the tests. Here's a summary for those who want to get straight to the point:
Thank you for reading. Please note this is my first review/comparison and I would like feedback. Thanks
