I have these http://www.overclockers.co.uk/showproduct.php?prodid=FG-073-AK

and wanted to use them on the rad (i didnt notice they were 4 pin) so heres where my trouble starts

I have a lamptron fc5 nice controller but the pins are 3 pin connector to which i have the alchemy Multi 3 pin extension


so my choices are as can see are

/1 find another extension type that will allow me like the alchemy ones to be able to controll 3 PWM fans per channel on my lamptron

2/ buy a new fan controller

3/ buy new fans

/4 hope you guys can suggest something i have missed :)

Your CPU fan header is a standard PWM header. So you can get a pwm splitter and hook them all up to it and control using AI Suite 3.
 
My rad is going on the bottom of the 900d case so i dont think that will work i think my best bet is to admit defeat and buy new fans for 30 quid.

Ill keep looking tho
 
With the lamptron fan cables being 3 pin, and the fans 4 pin, you can snip the side of the connector off to be able to take the 4 pin connector, just make sure you snip the right side off.

Yup, akasa do a five fan splitter that ive used with the akasa piranha fans. All controlled via the cpu header. If the mobo has an opt cpu fan header you could run upto 10 fans. Cable is a bit messy though.
 
How many fans in total? To use the 5 way splitter at most you may just need a single PWM extension cable to run from the cpu header.
 
will be 4 just now more later when I expand loop, in the end there will be 13 that's why I bought the fan controller it can handle 12, and the cpu one would be the rear fan it may be worth buying a 3 pin or sniping the plastic cap so I can fit the 4 pin on would that work? :)

But a 4 pin will fit a 3 pin and then work just like a normal 3 pin fan.

Is there space issues or something with the controller/controller leads/extensions?
 
the fan extensions I have have a plastic border around them so it only fits a 3 pin I may as suggested break abit off and see it if works :)
 
I run a similar setup e.g. PWM fans in the basement of the 900D running from the CPU_FAN header (I've currently got 23 fans hooked up to the cpu header).

I just use an extension cable from the CPU_FAN header down the back of the motherboard tray to the basement. I then use a Swiftech 8 way splitter (used to use Akasa 5 way one) to run power and PWM signals to my fans
 
Nice fink I've just knocked the corner off of one off my alchemy fan extensions and its working so will take a small amount of moding but it will work :), I got a response in customer services also but they have said that the air rippers would be no good for rads anyone else using them??

Iirc Nickolp and Whyscotty have used piranhas to good effect on rads. Static pressure is good on them as I used them on a k2 heat sink that is much thicker than most rads and very densely spaced fins.
 
Someone is CS is waffling or just mistaken :D

I have four of these. Haven't used them in a system yet, but I have put one up against a rad (AX360 fwiw) and airflow/pressure/whatever seemed pretty good to me at least.
I'd also take Nickolp and Whyscotty's word for it.
 
Great fans, id have kept them but i was going for a red/white/black theme in my setup, so swapped the piranhas for some corsair af/sp's from Nickolp.
