A-Top AT900 Mid Tower ATX

The Test

For full details on how we tested, please read AnandTech's case testing methodology.

The AT900 evaluation sample AnandTech received from Atop was equipped with two optional fans - the 80 mm intake fan at the bottom front of the case, and a second 80 mm exhaust fan mounted in the side panel. That 80 mm side panel mounted fan is not normally an option, but we were unfortunately not informed of this until after testing was completed.

The AT900 also did a surprisingly good job of keeping our test bed system nice and cool. The additional exhaust fan mounted in the side panel certainly helped quite a bit, but remember that it is not normally included. Maximum HD and case temperatures were even cooler than many larger cases, such as the Supermicro SC750-A and the Enlight EN-8950.

Once again, CPU temperature has generally shown to be most dependent on having a high quality heatsink and fan in AnandTech's testing.
