Sapphire RX 570 Pulse ITX SFF GPU Review

These sound results are not overly precise as I work in an area with high ambient noise levels. As such, don’t take these results as gospel truth, but more as a general indication of overall noise levels.

We take our measurements with the decibel meter on the top and middle section of the case, overhanging the side panel (power supply side, not motherboard tray side) by exactly 1 inch to avoid any airflow pressure coming from the exhausting AIO cooler.

I measured the sound floor to be 38 dBA, thus anything above this level can be attributed to the graphics cards. The power supply is passive for the entire power output range we tested all graphics cards in and all CPU and system fans have a fixed fan speed (25%) completely isolating them from any changes in temperature across the system.

Noise levels were measured after 5 minutes of load under three scenario: Furmark, Fire Strike and desktop idle in sequential order with 2 minutes downtime in between each test.

I don't have a result for FurMark as the RX 570 Pulse ITX card underclocked itself significantly to avoid damage, so its noise level reading was not representative of its performance under load. However, it peaked at 40 dBA in Fire Strike, and I measured a peak of 42 dBA during Grand Theft Auto V. These figures put the ITX card in the middle of chart, and it is definitely a whole lot quieter than AMD's reference RX 480.
