Scythe Kama Cross CPU Cooler Review

Test Setup and Methodology

Test Setup and Methodology

In order to test the Scythe Kama Cross CPU Cooler, I have decided to target the two main areas that should cover our broad spectrum of readers here at Overclock3D. I will be assessing the Scythe Kama Cross heat sink under the following conditions:

* Cooling performance (Idle, Load and Overclocked)
* Noise

The test setup for todays performance review will be comprised of:

* Intel C2D Q6600 Processor (G0 stepping);
* ASUS P5B Deluxe wi-fi/ App motherboard;
* 2GB's OCZ PC2-6400 Titanium RAM;
* CoolerMaster Stacker 830 case;
* 80GB Western Digital SATAII HDD;
* Scythe Kama Cross CPU Cooler and Intel reference heat sink, and
* Arctic Silver 5 thermal paste.

I have explained my testing methodology for each phase of the performance review below:

Cooling performance

I will be testing the Scythe Kama Cross CPU Cooler on my Q6600 (G0 Stepping) processor to assess the heat sinks ability to handle the heat-load of a quad-, especially since Scythe state that the Kama Cross is 'quad-core ready'. I will be running the Scythe Kama Cross CPU Cooler with the 100mm included fan, as well as an Scythe SFF21E S-FLEX 120mm (49.0CFM, 1200RPM)  fan. I have chosen to use a similarly spec'd 120mm fan simply to try and keep the noise level as similar to the default fan as possible. CPU load will be simulated using 2 x instances of  Stress Prime 2004.

Ambient temperature will be taken using a standard mercury thermometer and allowing it time to normalise. Processor idle/load and overclocked temperatures will be obtained using Core Temp Beta 0.95.4, and an average taken over the four cores...purely to make plotting the chart a little easier to read. All testing will be conducted 3 times and an average taken to ensure the uniformity of results. Both the Intel reference heat sink and the Scythe Kama Cross will be tested, removed, and then re-installed a total of three times to ensure the elimination of any poor mounting issues.

Furthermore; all fans present in the CoolerMaster Stacker 830 case will be turned off to ensure that the additional cooling afforded by them does not effect the results.


Possibly the hardest part of any CPU Cooler review is summarising the level of noise given out by the fan, should it have one included. The threshold for what is considered 'noisy' varies from person to person and therefore what I may consider quiet, another person may consider extremely loud. For this reason, all reviews from this point forward will be using a dBA meter to measure the level of noise output by the fan.

All noise measurements are taken in a quiet room with the dBA meter located approximately 200mm away from the heat sink  The results shown on the next page will incorporate the total noise emitted by the system above (inlet and exhust fans included), and the noise emitted by the Scythe Kama Cross heat sink with the 100mm and 120mm fans attached, respectively.  Furthermore; for the 100mm and 120mm noise tests, all other noise sources (fans, graphics card and HDD etc) will be eliminated from within the case.

Let's head over the page to see how the Scythe Kama Cross performed...

God I hate that twistlock system

looks like a quality cooler but the markets so saturated I find it hard to get excited about any air coolers whatsoever these days

anyway, another quality review mateQuote

Meh, it seems like a decent mid-range cooler. Would be good for the HTPC or just a family build, not really the OCing side.

Nice review mate.Quote

In a PC mag review this cooler caused the PC to run hotter than the stock cooler. Quote

Which PC mag was that?

It certainly looks cool, not that that's anything to go on Quote

Thanks guys it is a very capable little cooler.

Weird, I never found that. I didn't think anything could perform worse than the Intel reference cooler Quote
