Thermaltake Toughpower GF1 750w Power Supply Review

Fan Speed
In regards to the fan speed test, things were a little unusual. It’s possible that the results were merely a quirk of how it performed on our test bench, but the main fan seemed to maintain a constant speed of around 500rpm. This was regardless of the power output.
This isn’t necessarily a bad thing as this speed is amazingly quiet. In regards to the ‘Zero Fan’ mode, however, things got even more interesting.
If you’re not aware, a ‘zero fan’ mode is designed to only run the power supply fan when absolutely necessary. In fairness, many (of the better designed and mid-tiered) power supplies can run quite happily passively for long periods of time with no problems at all. So, what’s the point of it? Well, put simply, this operation mode helps reduce the overall noise your PC produces. One less fan running, right?
Across all of our tests though, it simply refused to run at all. Now, we’re absolutely certain that it was working. We can, therefore, only presume that the power supply never got to a temperature that it deemed it necessary to run the fan. If that is the case, then, at least in theory, it is truly excellent and again highlights just how well this has been put together. Specifically in keeping the components well spaced and, by proxy, making them better able to ‘breathe’.
