Thermaltake Toughpower PF3 1200W PSU Review

Fan Speed

So far, everything has performed excellently, with great efficiency, voltage regulation, and much more. However, I’m not overly impressed by the 120mm fan they’re using. It seems to be set on quite a high curve, hitting around 2200 RPM at 80% load, so it is audible. 120mm does seem a small fan for a 1200W PSU, and while it’s obviously doing a good job at cooling, I think a slightly larger PSU design to fit a bigger and quieter fan would have been even better. That being said, it’s completely silent at low loads and temperatures, so if you’re just watching YouTube or something, the fan stops.
