Lamptron FC5V2 Fan Controller Setup (final check I've got everything right)

post #1 of 17
Thread Starter 
Hey guys,

The fan controller is the last piece I need to sort out before ordering my new rig. I just wanted to run it by the experts to make sure I've got everything right.

I'm going to be using the controller to control all my fans and pump. I'll be running 16 x Silverstone FN121-P (8 running on each rad), 3 case fans and my Swiftech MCP35x.

I'll be splitting it up with 8 rad fans on their own channels, the 3 case fans on their own channel, and the pump on it's own.

Link to fans:

Link to Fan Controller:
http://www.allneeds.com.au/prod1349.htm

Link to Pump:
http://www.allneeds.com.au/category185_1.htm

Now, to keep the cable management nice and neat I want to run mini hubs to split everything up. Here is a link to what I'm thinking:
http://www.pccasegear.com/index.php?main_page=product_info&cPath=9_511&products_id=24877

It's a 5 port fan splitter hub, that takes a 3pin supply. So I just run a 3pin fan extension cable from the channel on the controller to the fan hub yeah? Then run my 8 fans from there (3 outputs will need 2 way splitters).

Does all this sound right to you guys?

My reasoning for choosing that fan controller is it has 30W per channel (I didn't want to go lower than that), and knobs and LCD display. I didn't like the full touch ones, and I certainly prefer knobs over sliders. I also like the LCD display for RPM.

Oh and one last question. When I'm looking at the fan draw, we calculate the wattage as the actual wattage (running) correct? Lets say we load up a 30W channel with 29W actual draw. It would be significantly higher than that for a small time during startup, but that shouldn't damage the controller should it? Or do we ensure even during startup it doesn't go over the 30W channel max?

Cheers everyone =)

Assuming, conservatively, that fan start up power is 150% of running power that would be 1.5 x 29 watts, or 43.5 watts.
Should be OK, but that's kind of pushing it to the limit. Like what about a power failure where the power glitches on and off a few times?

Why operate on the ragged edge? Lamptron makes other controllers that may be better suited to your needs.

hi, i have an option for you.

take two fans that are opposite each other and crimp them to one 3pin connector so then you would have 8 fans running with 4 connectors and then get this.


with mine i cut the wires to as short as they would go so they are close to the rad. then cable tie the split ends together and you ahve one wire running to the controller and no box.

Gotcha, so it's ok to go a little over but not much. Should be fine then as I'll only be running 8 fans per channel (31.68W at startup). The other lamptron controllers I didn't really like the style of, that's the main reason I chose this one.

If I was going to start cutting wires I would probably just join them all to one cable and forgo the connectors alltogether. I wan't to keep everything separate for moving / testing / modifying the rig. The case is pretty large (Phanteks Anthoo Primo) so there shouldn't be an issue with the mini hubs. I mean I could also, run a splitter off a splitter and achieve the same thing but I don't want voltage drop over the cables either.

Ah! Form over function. Just remember, if you put all the blue smoke back inside, it will work again.

Seriously, you should be fine.

dont run your pump from the fan controller. it is meant to get 12v permanently with a pwm signal controlling its speed.

I had a Lamptron Touch with a rated 30W per channel.
I was able to put as many as 20 GT-2150 fans on a single channel.
That would be 29W running, or 120W starting.
A Lamptron rep told me on this forum that you only need to worry about running watts, not starting watts with a Lamptron.
So just for fun, I started adding.more fans to see how far I can push my Touch.
The cpntroller shut down and no longer works now.
Apparently you can't run 40W of load (28 GT-2150 fans) on a 30W channel....go figure!

So I ordered the CW611..... should get here any day now.k
I won't be testing that one like I did the Touch.

I can't figure out which pump he is using.
If it's a PWM pump, he should only control it via PWM.
But it can be voltage controlled, however I hear that would shorten the life of the pump.
A non-PWM pump should be easily voltage controlled, providing sufficient wattage from his controller.

To me, that link displays 3 pumps:
The MCP355, the MCP655, and the MCP35X.
Only the 35X is PWM.
Maybe my browser isn't showing the page properly?!?!
