6. Test Results
After so many pages, it's time to take a look and see how the SwifTech Apex Ultra H20-220 water cooling package performed. For obvious reasons, we tested the Swiftech Apex Ultra H20-220 package under overclocking, since we don't assume a user will spend around $300 to have the CPU stuck at stock voltages. After pumping up the FSB to 450MHz and CPU voltage to 1.45V, we measured the following temperatures under idle mode. As you will see, we have a variety of conditions we thought would be interesting for you. First, we have the full speed mode, for the radiator and case fans. In this mode, the system produces the highest possible noise and probably the best performance. Then, we disabled the case fans to reduce noise, and after that, we used the included adapters to further drop the noise levels. But enough with the explanations, let's show some numbers.
The best air cooler we have tested in our labs comes from Titan, with the Amanda Tech model. Despite the fact that we had similar environmental temperatures, the Titan Amanda Tech performed better than the SwifTech Apex Ultra H20-220 water cooler. Now let's see how our water cooling product performed under full load.
The test results are very interesting. At full load, the Swiftech Apex Ultra H20-220 delivers 46.5° C for the Intel E6750 processor, while the Titan Amanda Tech around 53° C ! That's around 6.5° C less. Using the supplied 12V-7V adapter, we had a small increase in processor temperature, by 2° C. For the lowest possible noise level, the Swiftech Apex Ultra H20-220 produced somewhat worse than the Titan Amanda Tech, with 54° C.
Proceeding to the overall case noise, we have to say that the Swiftech Apex Ultra 220 is very noisy, especially at full speed, either from the radiator or the case. Don't forget that the radiator is attached to the case so all vibrations and noise pass through the case. Again, the sweet point is to use the 12V-7V adapter and have almost 5 dB less noise than the Titan Amanda Tech, and also much less noise from the radiator.
