PC Power & Cooling Silencer 750 Quad CF-Edition

Temperatures (Ambient constant 25°C)

With an ambient temperature of 25°C we have added a new test to our regimen. With the additional results we hope users will be better able to form an opinion about the performance of the test power supplies. Speaking of additions, we have also added a new graph which shows the two heatsinks and the exhaust temperature together. Hopefully, we are done with making any more additions, as adding any more graphs at this point will likely do more harm than good in terms of conveying information without overwhelming anyone.





These results at 25°C are clearly lower than at higher temperatures. The second heatsink which is the hottest is just getting up to 56°C and decreases together with the other temperatures at 80% load. This is caused by the fan which runs at over 2400 RPM at that point. At the highest loads it is running at up to 3800 RPM and therefore the curves all start decreasing. More fresh air is coming through the power supply and therefore the components are better cooled.

Unlike the OP650 from Silverstone we see that the two heatsinks in the Silencer have a similar temperature. At most they have just 10°C difference, which is most likely the result of the two heatsinks being in relatively close proximity to each other. Not only that but they also don't get as hot as in the OP650.
