Cooler Master Hyper TX3 and N620 Review

Methodology, Test System & Limitations

Methodology

For the duration of the testing, the system was running in an air-conditioned room, with the temperature regulated to maintain a steady 22 degrees Celsius ambient temperature. This was important because this would be the constant, while I test the variables (the coolers).

This temperature was verified using a temperature probe connected to a digital multimeter. The probe was placed adjacent to the 200mm intake fan at the front of the case.

To measure actual CPU temperature, Real Temp 3.00 was used because over time it has been proven to give accurate readings for Intel Core based CPUs. It was also easy to record the minimum temperature at idle and also the peak temperature during load.

Idle temperatures were recorded at the desktop with minimal system activity, resulting in the CPU being at less than 2% load across both cores.

For loading the CPU, OCCT 3.1.0 was used. Two separate tests were used to load the cores of the CPU to 100% for a sustained period of time. These are as follows and are described as stated by the program’s help section.

• CPU: OCCT – OCCT CPU test, where you’ll find the famous OCCT test that have been around for years now.
• CPU: LINPACK – Linpack CPU Test, based on a library provided by Intel. Similar to IntelBurnTest. CAUTION, it is VERY extreme and will make your CPU real hot.

Default settings were used for all tests.

Test System

The test system consisted of the following:

• Case: Cooler Master HAF 922
• PSU: Cooler Master UCP 1100w
• CPU: Intel Core 2 Duo E7200
• MB: ASUS P5E Deluxe X48
• RAM: G.SKILL 4GB DDR2-1000 PQ
• GPU: SAPPHIRE HD4870 1GB
• 4 Hard Disk Drives
• 1 Optical Drive

The purpose of keeping all four hard drives in the test system is to further simulate a real life scenario, instead of using only one so as to cut down on internal system heat.

Limitations

The stock settings for the CPU are 2.53GHz with its VID of 1.175V and this was used throughout the testing period.

The overclocked and overvolted settings were chosen based on a limitation. The CPU itself can attain a maximum stable clock speed of 3.8GHz. However, all the coolers except the Intel stock cooler was able to keep the system stable at that speed. Given this limitation, 3.60GHz with 1.400V was used throughout the testing period.

Now for the results of the testing.
