Sapphire Radeon HD 7770 Overclock Edition 1GB Graphics Card Review
Chris Hadley / 13 years ago
Noise is generally the bain of most consumers lives and in the hope of finding the quietest operation, we feel it’s necessary to show you the audio level of components. We use the same components throughout this test and use a sound level meter to record the audio level of the system with a passive graphics card installed. Once we have the level recorded with the passive card, we continue to change the graphics card for the one that we are testing. Due to us having the audio level recorded before installation, it gives us a guide to work with and shows that anything over our initial level is an audio gain.
Once again, we can see that the cooling department at Sapphire really know what it takes to make a quiet cooler. Like the 7950 OC, there is barely noticeable difference between idle and full load fan speeds keeping the noise down to a comfortable level all round.
