Antec Three Hundred Gamer Case


There were a few small things we'd recommend to Antec to improve the Three Hundred case (based on our sample):

  • Add some cable routing ties and tie-down points to the backside of the case (beside the expansion slots). Some of the cables we routed this way were loose.
  • Extend the length of the the audio and USB front access port cables. It would be nice if we were able to route the cables along the sides of the case, but we weren't able to do so since the cables were too short.
  • Include an extra 2 fans so that all of the ventilation holes can be populated. Noise wise, the fans all on low is very quiet, so adding two more at low settings shouldn't annoy anyone.
  • Include thumb screws that can be used for mounting 5.25" drives. It was nice to include lots of thumbscrews for the wider thread. It made the installation of 3.5" drives and the motherboard easier, but no fine thread thumbscrews were included.
  • Include an adapter to allow a 5.25" drive bay to be converted to a 3.5" external drive bay (similar to what was included with the Antec Sonata Plus 550 case).

Cooling Performance Test Platform

For testing cooling performance, circuitREMIX has created test bed configuration. The hardware chosen was picked to reflect that of a relatively modern computer system that an enthusiast may own. The heat production of the system is an above-average repesentation of one of these computer systems. The configuration of the system is as follows:

  • Intel Xeon E3110 overclocked to 3.6GHz
  • Thermalright Ultra-120 heatsink + 120mm Yate Loon fan
  • Asus P5E3 Deluxe motherboard
  • Corsair Dominator 2GB (2x1GB) DDR3 (1800MHz) memory kit
  • Diamond Multimedia Radeon HD3870 512MB PCIe graphics card
  • Seagate 7200.7 120GB SATA hard drive
  • Samsung SH-S203 SATA DVD-writer
  • Antec NeoHE 550w power supply

For temperature results, we are using temperatures reported by the processor (Intel E3110 core), video card (Radeon HD3870 GPU) and hard drive (Seagate 7200.7). The following temperature monitoring software was used (for each component, respectively):

  • CoreTemp 0.96.1 (average of each core)
  • ATITool 0.26
  • SpeedFan 4.33 (for S.M.A.R.T system of hard drive)

Besides the temperature monitoring systems of each of those components, we are also using external temperature probes to monitor air temperature (areas around the RAM Slots, Bottom PCI Slot, and Power Supply Exhaust). The ambient environment air temperature is also recorded to act as a control. The placement of these probes and the temperature monitoring hardware is illustrated in the image below.

Tests are conducted at both idle and load situtations. Idle status is is when the computer is running Windows Vista Business edition with no applications running, save for the temperature monitoring software (this software has very low CPU overhead). Load status is when the computer is running Windows Vista Business edition with OCCT running on all processor cores, ATITool 'scanning for artifacts', and temperature monitoring software active.
