Thermalright TR-TGFX 550 ATX v3.1 PSU Review

Average Noise

The average noise output exceeds 30 dBA, so it is on the high side. Given the unit’s efficiency and low capacity, the fan speed profile could be more relaxed if the quality of the parts allowed for that.

Noise remains low at up to 260W, while the 30 dBA mark is passed at around 280W. With more than 320W at 12V, you enter the 35-40 dBA zone, while with more than 395W, you enter the “noisy zone” where the fan operates at >40 dBA.

The 115V fan speed profile at light and moderate loads does not show major differences. The 35-40 dBA zone stays longer, giving less space to the 40-45 dBA zone.

  1. Can you do a review of the Thermalright TP-1000/1200? There’s a frustratingly low amount of information about it. Thanks in advance.
