The SilverStone FX350-G is good FlexATX power supply, but the stock fan loud and its showing its age with its mustard cables and choice of connectors. This fan noise can be improved by swapping to quieter fan, but at the cost of your warranty. Overall, its still a solid choice. We’d like SilverStone change the cables colour to all black and use a quieter fan in future revision.

DESIGN & FEATURES
FX350 has all black chassis with the cables being mustard. SilverStone have included black braided sleeving, which mostly hides the old fashion cable colours. There’s an included power switch, which is not present on any other Flex ATX power supplies, other than their own FX500.

|POWERDRAW||dB(A) at 60cm|
FAN SWAP (NOCTUA)
If your considering swapping SilverStone’s included fan for something quieter like Noctua’s, there are things you should know.
SilverStone’s included fan dimension is 40x15mm. Noctua’s fans are either 40×10 / 40×20. This mean you cannot use Noctua’s quiet 40x20mm fan with the SilverStone FX350-G. Noctua’s 40×20 fan is not rated to move enough air to keep the FX350-G cool and could cause overheating at 5.5 CFM. If your thinking of using Noctua’s 40x10mm fan, you’ll be at higher risk of the power supply overheating as Noctua’s 40×10 fan is only rated at 4.8 CFM. The Noctua fan cables would also need reversed for some of the connectors as SilverStone FX350 uses a different polarity on their included fan than Noctua does.
FAN SWAP (DELTA)
We found a compatible fan which is 40x15mm, and exceeds airflow specifications of the stock fan, while also being quieter. The Delta AFB0412HB is rated at 9.6 CFM and spins upto 7000 RPM.
The Delta AFB0412HB positive and negative cables at the PIN connector will require being swapped around as shown in the image below or the fan won’t spin up. We set the fan to intake as in most cases, you’ll want to be pulling cold air into the FX350-G from outside the case vs pulling hot air from inside a case.

Note: any modifications to the SilverStone FX350-G power supply will void the warranty and may produce suboptimal performance.
