For testing today we are using an AMD Phenom 1055T based system.
Antec Dark Fleet DF 85 Full Tower Case

Firstly let us have a look at the chassis design and airflow, as it comes ‘out of the box’.
As Antec don't include any front mounted fans as standard we are left with an dead zone at the front of the chassis. This won't really prove much of an issue if you are using an SSD or single 7,200 rpm drive, but for those of you with multiple drives and perhaps a few 10k Raptor units, this area could quickly heat up when under load.
All intake duties are handled by the 200mm Tri Cool fan at the side which pushed air directly over the graphics cards and motherboard. The remaining 2x 140mm and 1x 120mm Tri Cool fans handle exhaust duties.
We have placed thermal diodes in 5 case positions – 1; top optical drive bay position. 2; hard drive position. 3; top area between CPU and fan exhaust positions. 4; above PSU, graphics card (s) area. 5; motherboard central ‘dead zone’ area.
We test with our AMD 1055T at reference clock speeds and voltages. Nothing else is overclocked. Room Ambient temperatures in our labs are maintained at a constant 25c with air conditioning. Load is measured by running Cinebench R11.5 in a loop with Furmark, worst temperatures are recorded through a duration of 20 minutes.
All case fans were set to med way settings to keep noise to a limit (more on this later).
The case maintains internal ambient temperatures with our diodes at room temperature which is a great set of results. As expected the ambient air at the front 1/3 of the case raises a few degrees however the exhaust fans are powerful enough to ensure that still air won't hang, even this far forward.
We installed a 120mm fan at the front of the case – The SwiF2 1201 which we reviewed a while ago.
Several of the diode temperatures dropped by a single degree, specifically those at the front area of the case.
Next we cranked the system speeds, increasing core voltage on the 1055T and overclocking it to 4ghz. We left the additional 120mm fan installed at the front.
These are a good set of results only slightly higher than the DF85 we reviewed a while ago.
