These recordings were made with a high resolution, lab quality, digital recording system inside SPCR's own 11 dBA ambient anechoic chamber, then converted to LAME 128kbps encoded MP3s. We've listened long and hard to ensure there is no audible degradation from the original WAV files to these MP3s. They represent a quick snapshot of what we heard during the review.

These recordings are intended to give you an idea of how the product sounds in actual use — one meter is a reasonable typical distance between a computer or computer component and your ear. The recording contains stretches of ambient noise that you can use to judge the relative loudness of the subject. Be aware that very quiet subjects may not be audible — if we couldn't hear it from one meter, chances are we couldn't record it either!

The recording starts with 5~10 seconds of room ambiance, followed by 5~10 seconds of the VGA test system without a video card installed, and then the actual product's noise at various levels. For the most realistic results, set the volume so that the starting ambient level is just barely audible, then don't change the volume setting again.

ATI Radeon HD 5450 512MB: The Radeon HD 5450 is a very energy efficient entry-level card. As a result, it's easily cooled by the large passive heatsink found on the reference model. Its 3D performance surpasses all integrated solutions, but is still only suitable for gaming at lower resolutions. It does make an excellent HD playback card though, especially if it's used in a home theater setting; as a member of the HD 5000 family, it can bitstream Dolby TrueHD and DTS-HD Master Audio through HDMI, and is easily the most affordable card that can do so. For some, that alone makes it a steal for $50. Our only criticism is the fact that it's a two-slot design, yet lacks a DisplayPort connector and thus does not support ATI's Eyefinity multi-display feature. Ideally we'd like to see ATI's partners come up with versions using a single-slot passive heatsink that also support Eyefinity, if possible.

Asus EAH5750 Formula 1GB: According to the gaming oriented reviews at sites like HardwareCanucks, The Tech Report, and techPowerUp, the Radeon HD 5750 is a decent midrange graphics card with a small increase in performance over the HD 4850/4830, and is a competitive rival for the GeForce GTS 250. Its energy efficiency is somewhat better than the GTS 250, using 10W less on full load, but idling using 3W more. The Asus Formula heatsink/fan keeps the GPU fairly cool, but the fan control is a little to aggressive when idle; a lower minimum fan speed would be much appreciated. This model too lacks a DisplayPort connector but Asus has another version of the HD 5750 that has the more familiar dual-slot DisplayPort/DVI back panel layout that supports Eyefinity. The $140 asking price is reasonable, though you may also want to consider the faster HD 5770 for $25 more.

Our thanks to ASUSTeK and ATI/AMD for the video card samples.
