fan controller

post #1 of 13
Thread Starter 
hey guys so im trying that can run 4 pin fans on it. i cant seem to find one at all... it would be nice to also have a temp sensor connection on the controller as well

these are the fans

Because that's missing the point of a fan controller in the first place. The reason you have a fan controller is to control the power output to each unit, you don't want PWM to mess up your fan speeds....

To be honest though, I wouldn't bother with those fans unless you're looking at a colour scheme...

^^ that fan controller is a bit sucky for the price to be honest, it only gives 12w per channel from what I can find about it... That can be enough for just a single fan per channel, you'd still be better off with the lamptron series. the FC5V2 is pretty epic. either that or the lamptron touch.

oh i must have misunderstood the PWM feature. So is it possible to use 4 pin pwm with a 3 pin connector controller?
post #5 of 13
If there is room beside the ports then yes. to be honest though you'd be better off getting some sleeved splitters so you can connect multiple fans to each channel... Those however, will not allow room for your PWM line.

I have the Lamptron FC5 and it has room next to the connectors to fit 4pin fans. it also has temp sensors, adjustable color, and you can select voltage read or Temperature read.

Yes there will be room on the controller, but not if you want to connect a number of fans to a single controller... Actually, see if you can get 4 pin splitters.. That would work biggrin.gif

Bit dense on that one I was...

Sorry, but I am finding it hard to understand the point of this post.

1. "you don't want PWM to mess up your fan speeds" This makes absolutely no sense to me. As that controller only has three pin connections, PWM will not be involved at all. From what I can see, the layout is such that you won't be able to hook up four pin fan connectors at all, which may be what the background is for the later coment about three pin splitters.

2. "That can be enough for just a single fan per channel". True, but rarely. Most fans use very little power. For example
Gentle Typhoon AP15s - less than 1 watt
Swiftech Hellix - less than 2 watts
Noctua NF-S12-1200-D - 1.44 Watts
His choice fan - 5.4 watts, so it will be close but within specs to run two per channel.

Overall, I agree that this fan controller is not the best solution. The main issue will be one that can accommodate the connections, or he will need adapters of some kind to go from four to three pin.

The other solution would be to run two pins straight to power, and get a pwm splitter and control the speed off a motherboard header. This is one of the advantages of PWM.

1. Exactly my point, why get PWM on a fan when you're connecting it to a controller in the first place. You use PWM to control the fan speed in relation to the temps etc.

2. Scythe Ultra Kaze 3k rpm fans, awesome fans, 15w each. Might be 10... Either way that fan is overpriced for what it is. The lamptron has 30w per channel, cheaper and has a nicer finish.

skip the controller, use the red+black wire to your psu.. for power

run yellow+blue pwm controller wires to mobo, and use the pwm curves..

have all the control via mobo, and dont drain power from mobo.. now you can even run pwm delta's with a mobo controller, your welcome!
