I wanted to replace the stock fans in my HP 2810-24g from the noisy stock ones from (Nidec?) to proper silent ones from Noctua, namely their amazing NF-A4x20 FLX<\/a> running at DC12V @ 0.05A (0.6W) But my first attempt gave me a “FAULT” status and loads of errors in the event log. But I fixed it, here’s how:<\/p>\n\n\n\n

See, most fans nowadays have 3 Pins:
RED<\/strong><\/span> – DC Voltage +
BLACK<\/strong> – DC Voltage –
YELLOW<\/strong><\/span> – Tachometer<\/p>\n\n\n\n

Here the yellow wire is to detect a fault. Namely, if the yellow wire isn’t grounded the switch assumes there’s a fault<\/strong>. Fortunately, this is an easy fix!<\/p>\n\n\n\n

Installing the fans<\/h2>\n\n\n\n

This part is by far the simplest, use a Phillips screw driver, remove the old screws and the old fans will just get loose, take them off the case. Remember to save these screws and fans in case you wanna revert to stock. One more thing to note, the screws the stock switch fans use aren’t thick enough for these Noctua fans, use the ones that come in the Noctua packaging! Lastly, remember to get a different bit on your screwdriver for these as they’re slightly bigger than the chassis screws.<\/p>\n\n\n\n

Pardon the dust, this old bat has seen some stuff<\/figcaption><\/figure>\n\n\n\n

Make sure as well to have the label on both fans facing inward, so they blow air INSIDE<\/strong> the switch.<\/p>\n\n\n\n

Tricking the switch<\/h2>\n\n\n\n

Now, find an led, or a resistor, or a clip, anything metal that is about the size of the fan pins. We’re about to make a dirty jumper! Now:<\/p>\n\n\n\n
