My Lian-Li 343B Case 3-loop Project - Initial Pump Testing

[Cascades]

Well, the three pumps were making a weird, low-frequency noise that I could stop by pressing on the center of the vertical panel. I tore the system down and will be getting in some 1/4" sound-proofing material tomorrow to place on that panel. Hopefully that will stop this weird noise.

To be able to apply the sound-proofing material easily, I took apart the case. Here's a picture of the case with all the panels out:



Here's a couple of pictures of the pumps and the pump shelf:




Sunbeam Fan Controller: This is a great little fan controller that can control up to 20 watts on each of the four channels. However, the LEDs on the front are way too bright and can light-up a dark room! To reduce their brightness, I installed a 10K-ohm resistor to the center lead (Gnd Lead) of each of the LEDs and this worked great. Channel 1 controls the fans on the vertical MCR-220 radiator to the left, Channel 2 controls the fans on the MCR-220 radiator on the top panel, Channel 3 controls the fans on the MCR-320 Vertical radiator to the right, and Channel 4 controls the remainder of the fans in the case. Thanks to Jason Padrick on OC Forums for this idea.

Here is a picture of the placement of these 10K-ohm resistors:



I should have everything back together this weekend.

Cheers!

I have the same fan controller, and wanted to disconnect the LEDs. Question is, can I simply cut the wires thereby breaking the circuit, or do I need to reconnect the circuit after breaking the connection with the LEDs?

I think the LEDs are placed in parallel with the rheostats, so breaking the circuit should be ok, but not sure.

If you want to completely disable the LEDs, just cut the center leads. You could cut the lead where the lead bends down and slightly move it out of the way. If you ever wanted the LEDs to work again, just resolder the leads back together.

The variable pots are not in the same circuit as the LEDs.

Thanks for the info. Sounds simple enough that even I should be able to manage that

Keep up the good work.

More notes:

**A note about pushing 7/16” tubing onto 1/2” barbs: I have read about different techniques of pushing the tubing onto the barbs, and I tried every one of them. But what really works well for me is to use a very small amount of olive oil on the barbs and push the tubing on firmly. Works great every time! To get the tubing off, make a very slight cut on the end of the tubing with an exacto knife, and the tubing easily comes off of the barb. To re-attach the tubing, cut the tubing evenly and reapply. (You loose about 1” of tubing)
