Corsair Obsidian 450D Mid-Tower Computer Case

Cases & PSU/Cases by leeghoofd @ 2014-04-28

Corsair introduced early this year at the CES fair another case to the strong Obsidian lineup: the Obsidian 450D. Being labeled as the smaller 750D variant it blends in perfectly between the existing range from the humongous full-tower 900D model to the cube shaped Obsidian 250D. The 450D model is here to satisfy the need for a spacious interior combined with an optimized air flow, ready to fit crazy customized water cooling equipment. Nevertheless combining this with the sleek looks and design, typical of the Corsair Obsidian series.

The Build, Temperature and Noise Results

The hardware comprises of the following parts:

  • ASUS Rampage IV Extreme X79 mainboard
  • Intel i7-3960X OC'ed at 4.5Ghz 1.37Vcore
  • Corsair Hydro100i cooling
  • 32GB CORSAIR 2400C10 RAMs
  • 1 x AMD 7970HD graphics card
  • 2 x Western Digital 1TB Caviar Green Hard Drives
  • 1 x SAMSUNG 840 PRO 256GB SSD
  • Corsair AX1200i Power Supply.

The build was completed in a half an hour, with no complications found at all; that would be a first if one uses components of the same manufacturer and installation hiccups took place. The cable routing is a breeze thanks to the numerous cutouts and ample space between the motherboard tray and the side panel.

 

Installing an over-sized graphics card is a no-brainer too due to omission of a second removable HDD cage, thus the GPU is positioned directly in the air flow of one of the front 140L Fans. It hardly can get any better than this.

 

 

 

 

 

 

Temperature results:

For the IDLE tests we allow the setup warm up during a 30 min period. The temperatures of the CPU cores are monitored by the Realtemp software. For the stress test we go flat out and test our the six cores of the overclocked i7-3960X CPU (4500MHz) with the Prime95 64bit software with a custom 12-12K setting. For the GPU test we ran a 3 time loop of the Futuremark Vantage 3D bench software to heat up the graphics core.

 

 

The 450D mid-tower case has got nothing to fear from its bigger brother the 750D; Corsair's claim for a mid-tower case for your big cooling needs seems valid. The open design and the direct air flow on the installed GPU(s) from  the front intake 140 Fans is keeping the installed components as cool as the when being installed in the bigger full-tower version.

 

 

Noise-wise the utilized fans have pretty great cooling versus noise ratio, measuring around 28dBA when being run full blast, however we have to make the remark that due to the open nature of this case, the installed components are a bit more audible then more closed designs.
