Noise measurement
We want to shed some analytical light on the system noise levels generated when high-end cards are installed. To this end, we're using a PCE-318 noise meter placed at the front of a Corsair Obsidian 700D chassis that has the side panel on and card(s) screwed in. Only the test system is running in a quiet room with a sound floor of 28dB. Decibel readings are noted for idle, load (COD: Black Ops) and super-load (FurMark) after 10 minutes have elapsed.
Middle-of-the-pack noise performance means that, unless you're particularly distracted PC noise, the PowerColor PCS++ HD 6950 is a fine choice for a gaming-centric system.
