Arctic Accelero Mono Plus VGA Cooler Review - Performance


Test System:

CPU: Intel i5-3770K @3.5GHz

Thermal Paste: Pre-applied thermal paste

Motherboard: ASUS P8Z77-V Pro

RAM: 2x4GB Patriot Viper Xtreme II 1600MHz DDR3

GPU: ASUS GTX 560 Ti 448 Core

OS HDD: Patriot Pyro 60GB SSD

Secondary HDD: Patriot Wildfire 120GB SSD

OS: Windows 7 Professional 64-bit



We want to evaluate both cooling performance in conjunction with acoustic performance.  To do so, we tested at both stock and overclocked states, and ran through the Aliens vs. Predator benchmark at the highest settings.  The AvP Benchmark Tool is very consisten and provides a heavy real-world load on the GPU.  We used ASUS' GPU Tweak software to monitor the thermal and fan states of the GPU during testing, noting the peak temperature and corresponding peak fan setting.  During the test, we will also make notes on the acoustic performance as well.


We observed we had to experiement with the voltage settings a bit more to get our overclock to stick in a stable state, which we aren't sure is just a coincidence or of the lack of direct airflow over the VRM components is to blame.


Stock Settings:

GPU Clock:  830 MHz

Memory Clock:   1002 MHz

Voltage:  1.012V

Overclocked Settings:

GPU Clock:  910 MHz

Memory Clock:   1050 MHz

Voltage:  1.100V



I've always been extremely happy about the performance of ASUS' DirectCU II cooling system, and was a bit skeptical that I'd find the thermal and/or acoustic performance of the Accelero Mono Plus anything to write home about.  I was dealt a surprise.


Stock (830/1002 MHz GPU/Mem @1.012V)

Overlcocked (910/1050 MHz GPU/Mem @1.100V)

ASUS DirectCU II Accelero Mono Plus ASUS DirectCU II Accelero Mono Plus
Peak Temp °C 64°C 53°C 72°C 62°C
Peak Fan % 47% 37% 54% 45%
Noise Level Very Quiet Near-silent Moderate (Audible Outside Case) Near-silent


To be honest, I was a bit taken aback by how cool and completely quiet the Accelero Mono Plus was.  I ran the benchmarks several times, ensuring the settings were still at the max settings.  The results came back the same each time, and the performance is really quite outstanding.  I was always happy that the DirectCU II, as it prevented thermal limitations and is also very quiet by stock cooler standards.  The Accelero Mono Plus simply does a great job, dropped temps by an impressive 10°C under overclocked load and 11°C under stock load, and was literally whisper quiet.  I listened to the system both open and closed, and even with my ear up to the GPU, couldn't easily differentiate the noise from the Accelero Mono Plus and the Cooler Master TPC 812 cooling the processor.  If you're someone who puts high value on quiet operation, the Accelero Mono Plus won't dissapoint, although it's certainly less aesthetically-pleasing than other coolers out there.

The i5 3770k doesn't exist :D

Good catch! I'll fix my fumbly-fingers mistake.
