We use the following programs to test the CPU’s temperature: SP2004 & 3DMark 2005. The diagram shows CPU’s core temperature when CPU loading is 100% using different coolers. When using Xpressar,12cm fan is at 1600rpm, CPU’s temperature is at 35 degrees when fully loading; liquid cooling is at 2400rpm, 55 degrees and air cooling is at 3000rpm, 75 degrees. The result shows Xpressar require less energy but the performance is better.

Note: The test environment setup: Three computers with identical specs, the only difference is the system cooling setup by Xpressar™, LCS and Air cooling.
