Cooling and Noise Levels
| Sound Pressure Level | |
| Load | dB(A) |
| 10% | 0 |
| 20% | 0 |
| 50% | 0 |
| 80% | 0 |
| 100% | 0 |
| 110% | 0 |
Since there is no fan, there's not much point in measuring sound pressure levels, but what about noise from the electronics? There is nothing, no matter if there is a PC case between our ears and the PSU or not. No coil is singing, no capacitor is squealing, and we've got a dead silent PSU! Of course, we can't say whether the CPU, GPU, and motherboards will be up to the same task. Even conventional hard drives are "loud" by comparison, so silence enthusiasts will probably want to go the SSD route just to be sure.
| Temperature (Ambient/Exhaust) | |
| Load | (delta (t)) ° |
| 10% | 2 |
| 20% | 3 |
| 50% | 7 |
| 80% | 10 |
| 100% | 11 |
| 110% | 13 |
The difference between the ambient and the exhaust temperature is very low. We've tested the power supply with a room temperatur of 25 °C.

Don't know why I never posted a comment sooner, but I got one of these ages ago, and it's still going strong over six years later.It's been used in two different builds now, and currently in use for a small form factor gaming PC, in a Rajinteck Metis case, which mounts the full-sized ATX PSU vertically at the front. While I'm not going fanless, this arrangement actually works really well for this PSU, as my CPU cooler is able to draw air in through the PSU before exhausting it out the back, which is fine, as with the PSU's high efficiency it doesn't generate much heat at all, and I have just a single fan cooling everything currently in my system, making it nice and quiet.
In future I'll be adding discrete graphics (I've gotten a lot of mileage out the Ryzen with Vega's onboard GPU so far), so that'll be a second fan, it will also be pulling air through the PSU and exhausting it at the back, so I don't expect any issues. Plus the PSU easily gives me the headroom for that.
In such a system as PSU with built in fan would either starving the interior of the case of air (by pulling from inside) or pushing air into a tiny case that only really needs a good exhaust fan to guarantee good airflow.
Sure, it was a hefty price tag for minor benefits, but I've been pleased with it, and will buy fanless again if I can get one to the same high standard (or better).
