TEST RESULTS: Test System with ASUS Radeon HD 6850

For our final test we moved back to a single hard drive but threw a modest graphics card into the mix, an ASUS Radeon HD 6850. This is not an option we would recommend or use ourselves, but simply a quick check on BitFenix's claims of Phoenix versatility.

The addition of the HD 6850 didn't have much effect on the system at idle. Internal temperatures were only marginally higher and the added noise from the GPU fan only accounted for an extra 1~2 dB. On full load however, things quickly turned south, with the CPU and PCH heating up 17°C and 13°C more respectively than when we were using integrated graphics. These temperatures weren't high enough to elicit concern but it shows you just how much of a thermal impact even a ~130W GPU like the 6850 can have. More importantly, in order to keep the GPU at ~90°C, the GPU fan had to be pushed to over 4000 RPM, resulting in an earsplitting overall noise level of 34 dBA@1m. The poor cooling is directly attributable to the absence of a side vent and inadequate front vents.



Sitting idle, our HD 6850 had a fairly innocuous sound. On load, the GPU fan's high speed shifted the noise character toward higher, more annoying frequencies.

While the Lian Li PC-V354 is a microATX case, its size and functionality are very close to that of the Phenom, making it a suitable candidate for a comparison. Also, the test components are very different but as the overall power draw for both machines was eerily similar, the thermal load in each case can be considered equivalent.

The PC-V354 takes this contest with ease, winning in every category, even in CPU temperature despite being paired with a less capable down-blowing CPU cooler and slower fan. The noise level is a complete rout for the Lian Li case, which is aided by a more traditional vertical motherboard orientation and two intake fans mounted to a fully ventilated front bezel.

AUDIO RECORDINGS

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.

Each recording starts with ambient noise, then 5~10 second segments of product at various states. 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 while comparing all the sound files.
