Silenx Effizio Extreme Review



Finding out how the Effizio performs is the object of this exercise, so I will be making a comparison of the CPU temperatures in both an idle and loaded state. Both will be made while the CPU is at the stock voltages and clock speeds, as well as when the CPU is overclocked and over-volted. This will help to show what kind of cooling performance this cooling solution from SilenX has to offer when compared to other socket 1366 compatible high-performance cooling solutions. These cooling systems will be tested head-to-head as they are delivered from the manufacturer. To test the idle temperatures, I will allow the computer to stay in an idle state for 30 minutes and take the idle temperature at this point. For the load testing, I will use Prime95 version 25.11 and choose the blend testing and allow the processor and memory controller to heat up to the maximum temperatures. The time frame is a four-hour run, to allow the temperature to peak - usually at or around the 14K test. I will use Real Temp 3.0 to take the high and low temperatures and average the temperatures generated over the four cores as my reported temperatures.

Testing Setup:


Comparison Heat sinks:







Testing the SilenX Effizio shows that the heat sink assembly does a decent job of cooling the processor down in both stock and overclocked scenarios. The tower design seems to be the way to go for after-market heat sinks these days with the amount of heat pipes and their size increasing to meet the demands of the enthusiast. The Effizio, with its single fan configuration, delivers results similar to the CoolIT Vantage, the CoolIT ECO, and the Thermaltake FRIO at low speed, while performing better than the Gelid Solutions Tranquillo with temperatures well below what the stock Intel heat sink delivers. When the CPU is overclocked, the Effizio still keeps pace and finishes in the middle of the pack with a performance similar to that of the CoolIT Vantage ALC - all while remaining silent. The fan controller does help reduce the noise signature to a point where the fan is inaudible, but when the fan is quiet to begin with at maximum speed, the case fans or power supply will most likely make more noise. When I pushed the clock speeds higher, the temperatures did rise further, peaking at 79 degrees Celsius when running the processor at 4.0 GHz. While that seems high, it is only eight degrees warmer than the Intel solution delivers under load at 2.66 GHz, so when you look at it in that light, it's not too bad of a trade off.
