Antec High Current Gamer Extreme X850 Power Supply Review

Fan Speed

When it comes to the fan speed, our results are a little unusual. Specifically, that regardless of whether we used hybrid mode or not, the power supply did not once deem the fan necessary to operate. This isn’t entirely unusual and we have seen it before. If nothing else, it indicates a very strong design which allows for an impressive amount of passive heat dissipation. Just to be clear as well, I left this power supply running for 30 minutes at 100% load and not once did the fan engage. Yes, inside a chassis things will get warmer. I do, however, still doubt that you’ll ever notice this fan running.
