Need a 1200-1500rpm 6CM Fan

[neonplanet40]

HI guys, as per title.

Need a fan no faster than 1500rpm due to noise. I can't connect any kind of controller as it is for an LED light heatsink.

Any ideas?

Voltage?

I don't know. Way ever a standard pc fan has. I have a fractual fan in now. But it's 3000rpm. Supposidly silent

Assuming:
You require a 120mm?
Have no max price?
Mean at least 60cfm?

Then Noctua F12 is the way to go for the best CFM. Although slightly on the louder side.

Edit - seems that's a PWM fan - at max duty rate (i.e., no controller) speed is 5,900 1,500 is slowest regulated speed - sorry.

If power consumption isn't a factor, then resistors (or better a regulator) to bring it down to 7v will be cheaper.

I am not too good with wiring etc herulach. Thank you Peter! Thats what I am looking for! Enpensive for a fan!

Damn, completely mis-interpreted that........

See my edit don't think it is what you want.

Ahhh! lol glad it didnt hit buy yet. I am finding it impossible to find a low speed fan.

Is it an aquarium light or something? Any of these will be more or less silent, even though they're all faster than that. http://www.quietpc.com/60mmfans

1500rpm in that size fan is going to move barely any air.

[neonplanet40]

yes it is for an aquarium light. I have this in it now - and it sounds like a lawnmower!

I have used 120mm and the 40mm fans from Noiseblocker and really like them. They also do a 60mm that spins at 1600rpm:

Not too expensive either.

In this one. It says it comes with a resistor to reduce to 1200 rpm. In my light there I can only wire up 2 wires. SO I dont think I could use this?

Thats just a resistor that sits inline with 12V. you could actually get the same cable and use it on your existing fan.

How would I wire it though? In my light I can only connect a red and black wire. No where possible for a third
