To test the DeepCool Ice Matrix 400 we used an Asus Crosshair V Formula motherboard combined with an AMD Phenom II X6 1090T Processor. For our overclocked results, the CPU was clocked to 4.0 GHz using a baseclock of 200MHz, a multiplier of 20x and a core voltage of 1.45V.
Test System
Processor: AMD Phenom II X6 1090T
Motherboard: Asus Crosshair V Formula
Memory: 4 GB (2x 2GB) Kingston HyperX Genesis DDR3 1600MHz
Thermal Paste: Arctic Cooling MX-3
Graphics Card: HIS Radeon 5550 Silence
Chassis: NZXT Source 210
For our temperature tests we set both fans to maximum and loaded the system for 15 minutes using Prime 95. We then restarted the system and left it idling at the desktop for 15 minutes before recording temperatures. Room temperature was maintained at 22 degrees Celsius for the duration of the tests.
The cooling performance is what we would expect at stock settings but when overclocked and under load, the CPU does get a little hot for our liking. We wouldn't want to be running this CPU overclocked with this temperature for an extended period of time.
In our noise level tests we switched off all the case fans so we are just taking into account the noise generated by the cooler itself.
The noise level was recorded with the Cooler at maximum speed. It was reasonably quiet at this speed, recording only 34.9 dBA on our noise level meter. While this is still audible, if you put the fan in PWM mode the noise level is much lower – below the 30 dBA minimum sensitivity level of our noise level meter.
