Gigabyte Radeon HD 7770 OC 1GB Graphics Card Review

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.

At idle, a low 46.1 dBA was had, showing that this large fan really does compete with some of the triple fan designs that we see on other cards, including Gigabyte’s own. When put into a load state, the acoustics only rose to 53.2 dBA, which is still very quiet when looking at the grand scheme of things.
