Looking for a cheap 4-pin PWM fan controller

That can supply 30W per channel. Is there such a thing?

Well, no. A true PWM controller modulates speed via a PWM signal along the fourth wire; the fans get their 12 volts from wherever so it wouldn't make sense to rate the controller's output (i.e, you can plug the fans into any 12 source, fan header, molex, sata, etc. so it makes no difference what the controller is capable of).

If you want to use existing PWM controls from the motherboard header for multiple fans Akaska makes PWM splitters that split the PWM signal to multiple fans (which get their power from sata or molex). If you want to manually control the PWM signal, Zalman makes a device called PWM mate that will vary the PWM signal (again, the fans get their power from molex or sata); interestingly enough, these two devices can be used together to control multiple fans manually via varying the PWM signal.

If on the other hand you are looking to use your motherboard's PWM signal to control fans via voltage control, Sunbeam makes a 30 watt per channel controller called the Rheosmart. I have no idea how well it works though as I have not personally tried it.

I see. It sounds like the PWM mate is what I'm looking for. So the PWM mate allows the fan to draw power directly from something like the PSU?

Edit: It seems the PWM mate is out of production. Maybe a common fan controller is my only option.

I normally use the CPU PWM fan header and / or GPU PWM fan header with PSU powered PWM splitter like Gelid or a hub like Swidftech. More info in "Ways to Better Cooling" link in my sig. 1st post is index. Click on topic of interest.

I don't think that's what I'm looking for. I want to be able to manually control them with sliders or a dial.

Can anyone recommend a cheap fan controller that will work with these?

Plenty of fan controllers at Newegg and one PWM that I saw.
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=fan+controller&N=-1&isNodeId=1

And a link to Amazon.

Your Delta is rated at 1.06 amps so you need a controller with channels that can handle 1.06 amps. Personally I would get one that could go to 2.0 amps/channel to be safe. Just make sure that the overall amp rating for the controller will handle the total number of fans you want to plug into it.

Using mobo is quick and easy.
Just grab with mouse, slide and click. Often easier than mechanical controls
