Looking at the chart provided by Tuniq, we see that the Extreme series Tower 120 beat out it's predecessor consistently by about five degrees Celsius both at idle and under load in stock and overclocked configurations.
Benchmarking on my system we will be compiling temperature data using OCCT Linpack tests. I am using the Tuniq Tower 120 Extreme with the accompanying Tuniq MX-3 paste on an Asus M4A79T Deluxe AM3 platform and a Phenom II 955 Black Edition overclocked to 3612.2 MHz. I gave the paste a good 10 days to properly burn-in. During this time I saw a 4-5 degree Celsius drop in temps as the thermal material set. This brought me to about thirty-three degrees Celsius idle. In the past, my overclock has been limited by temperature. This CPU has a thermal limit of 55 degrees Celsius, and the best load temps I could get with air with previous coolers was around 52.5c under load. As you can see by the info in these charts, while running Linpack 100% CPU usage, my chip was topping out at 44.5 and averaging 42.5 under load. That is 10 degrees Celsius below my previous best, and should allow me more temperature headroom to strive for a higher overclock. A truly great result for any air cooler. The Tuniq Tower 120 Extreme has proven to be quite the performer.
Move ahead as I wrap things up with some final thoughts and a conclusion.
