Test System & Test Results

TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.

While testing both at idle, the aluminium ZT-560D comes in just below the average at 57.5 degrees. I knew copper is a better thermal conductor, but I was a bit shocked to see an almost three degree jump in performance with the ZT-570D registering 54.8 degrees.

Under load the gap lessens between the coolers, but both coolers move up a couple places in the listings. A two degree difference is all that separated the copper for aluminum models here.

35 dB is barely audible. The blue LED fan at 7.5V is running about 1000 RPM and you have to get right on top of the fan to hear anything.

At 2300 RPM with 12V coursing through the PWM connection, the fans do make a fair bit of noise. While not the worst on the list, it is a bit louder than the average coolers we have tested with 80-92mm fans.

ABOUT THE AUTHOR - Chad Sebring

Jumping into computers for just the aspect of gaming is how it all started for me. After a solid year of gaming, I caught the overclocking bug. With overclocking comes the need for better cooling, and I have had both air and water setups to tinker with. With a few years of abusing computer parts, I looked for something new. I then decided to take my chances and try to get a review job with a online site. As an avid overclocker, I am always looking for the next leg up in RAM, cooling, as well as peripherals technology.
