I need a fan controller for my vantec tornado ...4pin power 3pin monitor. Any idea which is good and uses the 4pin? I don't need anything fancy on the front panel just something that will be effective.
the rheostat looks nice ...everything else I see on the links are way more than I need.

You could also just use those switch thingies and run it at 7v.

Why not just build one yourself? You'll need an LM-370T (I think) adjustable positive votage regulator, a to-220 heatsink, a potentiometer, a resistor and a few caps...
ah yes mac, 12-5=7, that is the way to do it.
Don't use a pot on a big fan, they will get real hot.
If you want variable speed buy or build a regulator

They make high-amp pots,but they are big and chunky. Rheostat for a stereo volume control would work, mounted to back side of a 3-1/2 or 5-1/4 face plate. Adapt power at input from harness, pins are cheap at JameCo and the extractors for them are also available there.
Some Jameco part numbers for power harness pins:
Male: CP42729
Female: CP42729
They also have power harness extractors, but you can make a one-two time extractor out of a round coffee stirrer or SMALL plastic straw (you will get to cut straw lenght wise all teh way through, then overlap walls a bit to get it right diameter, it goes into Connection (where connectors go together) side of both kinds of power harness connector. I strip connectors off of old PSUs, but connector shells are also available from JameCo. They also have rheotstats and pots that will be big enough ampacity for what you want (think RADAR control circuitry).

Ageek... ONE click, ONE!
The 80mm tornado draws ~1a @ 12v; there are very few pots that will handle it, you'd need a rheostat instead. Also, with that kind of power draw, the heat generated by a straight adjustable resistor is going to be absurd. You should use a positive adjustable voltage regulator.
The problem with using a variable resistor to regulate fan voltage is that all of the 'unused voltage' gets turned directly into heat.
Voltage regulators get warm, but not that hot.
I saw one revently that handles 5 or 6 fans. Two are just high/low switches and the rest are variable. The high/low connectors were built for higher power fans. But I can't remember the brand name.

Zalman. And the Vantec one is better.

The DigiDoc 5 handles big lods well and is an awesome tool. But it is probably too expensive for you guys.
I have a digidoc, just no 3 pin fans or temp probes....... kinda makes it a tad useles.....
I tried using a pot on my 120mm fan at one point.... and the pot kinda.... set on fire..... yeah....
See, this is why I don't want to go watercooled....

You mean you don't want to mix water and electricity???;) But that way if yoi have a fire the tubing will melt and put out he fire. ///yea, yea, that's it, uh huh!///
my digidoc can only turn fans on and off, not adjust the speed.
I had an enermax 3.5" unit, it could NOT handle my cpu fan (Sunon equivalent of a Vantec Tornado).
I now have a Noise Isolator, and I'm very happy with it.
I've heard good things about the nexus fanbus, but I haven't use it, so I can't endorse it. If you're in the market for a rheobus for that particular fan, I recommend the noise isolator.

LeonardoWake up and smell the glaciersEagle River, AlaskaIcrontian
same brand, but I got this one. can control 6 fans (2 simultaneously per knob) and 2 case light kits. I bought it from sidewinder, and I'm very impressed with it.
edit: this is the enermax unit i mentioned, it can not handle the output of a tornado or tornado-equivalent fan.
Mac you kicked ass, that helped me out!! yay!! no more noisy comp!! and my temp is just as good!!
THANKs!!
Fantastic!
I have changed several friends computer's from a 5-fan screamer to a near quiet system that way without loosing to much flow.
Changing the fans in the psu helps a lot as well.

You could always build one yourself.
Can you live with a steady voltage or do you need to be able to adjust it? 5 minutes and a plyer is all it takes to use that fan at 7 volts.
which wire do I pull I don't recall?
thanks again for all your help!
A couple of minutes only.
A picture says more than thousand words the say.
Never mind the little yellow bit of cable. It's from something else and isn't connected in any way.
thanks dude!

I thought that the svc rh35 was the same as the noise insolator rh35 with these specs:
• 4 Channel Output
• 13 Watts per Channel
• 12V 10% DC Input
• 12V PWM Output to Fans
Includes:
• 1x 3.5" RH-35 Fan Controller
• 1x Y-Splitter Power Cable
• 2x 3-pin Extension Cables
• 4x Mounting Screws (In a Bag)
• 1x Instruction Sheet
The NI was the one I was after but I didn't order it anyway so no biggy.
Can't figure out where to get the NI.
plycon has a 3.5 with these specs for $18.99
4 Channels.
13 Watts per channel.
Uses a standard 4 pin 12v DC power supply plug for power.
THANKs!!
