Alphacool Extreme Pro Review (Water Cooling)
 

The system idled at around 40 degrees C on the day of testing, with a room temp of about 25 degrees and a case temp of 31. The high temperature of 44 degrees C reflects about an hour of burn-in using the SiSoft Sandra CPU burn-in test along with Seti@Home running in the background for a combined and constant 100% CPU usage. Interestingly, only 30 seconds or so after the end of the tests the CPU dropped to 41 degrees. The cooling system did an excellent job of dropping the CPU almost immediately to where the normal idle temperatures were.
