This is an upgrade for all LRS-350 power supplies!
How much quieter? Well, stock fans are 34dB, quite loud. These premium upgraded fans are only 24db, which is exactly half as loud. We have researched over 90 fans and have determined that this is the only fan on the market that moves exactly as much air as the stock fan, yet is twice as quiet! Because it moves the same amount of air, it doesn't void your warranty, and ensures your power supply will last it's rated lifespan.
This upgrade includes 2 Scotchloc connectors. Just cut the wire from your old fan, insert the wires from the new fan (just match red to red in one connector and black to black into the other connector) and squeeze with pliers. Takes 60 seconds and no soldering or stripping.
