Thermal Characteristics & Test Setup

Before we rolled up our sleeves for the benchmarks, we wanted to get a sense for the general performance, thermals, operational voltages and noise level of the system under heavy load. 

System Vital Signs
Temps, Speeds, Voltages And Acoustics - Stock Out Of The Box

We fired up instances of Folding At Home and "rthdribl" (The DX9 Real-Time High-Dynamic Range Image-Based Lighting benchmark) and proceeded to take some simple measurements with PC Probe II, the bundled health monitoring software that Asus packs in with their A8R32-MVP motherboard.


OMEN CrossFire Full Load

OMEN CrossFire No Load

We observed that the system with both GPUs and the CPU fully loaded, while overclocked at 2.95GHz, still only reported a 51oC CPU temperature and a 40oC system board temp.  CPU voltages required for this level of performance were in the 1.54 - 1.55 range.  The system exhibited excellent stability during our stress testing and never faltered during our forthcoming benchmark analysis.  At idle the system dropped back down to a cooler 40oC CPU core temp.  Clearly the OMEN CrossFire's liquid cooling system was performing very well.  

From an acoustics perspective though, the OMEN CrossFire a121x certainly isn't the quietest machine we've ever tested. It's fairly quiet, relatively speaking, versus most water or liquid-cooled setups we've come across, however.  At these speeds and feeds, we're certain virtually any air cooling setup you could put together would be louder, so ultimately we're satisfied with the OMEN's balance of performance and relatively quiet operational characteristics.
