The CW611 has six channels and each can perform one of several tasks. You can hook up a 3-pin pump, 3-pin fans or even a flowmeter, although the latter is obviously for display purposes only. Connecting a flowmeter allows you to display the flow rate in either litres or gallons per hour and with the per-channel alarm function, you can tell the CW611 to sound an alarm based on the flow rate.
With 36W available on each channel, you're not just able to control fans but water-cooling pumps too. If you've owned a variable speed pump like Laing's D5 Vario, you'll know how much quieter they can be by running them on their lowest speed with little or no difference in temperatures too.
At the top of the PCB are the six 3-pin fan headers and bottom right are the 2-pin thermal probe headers.
Included are six 70cm 2-pin thermal probes, albeit without any adhesive pads, which attach to a bank of headers on the rear of the CW611 - you can of course also use coolant temperature probes to base you fan control on coolant temperature too. Six 50cm 3-pin fan cables are also included and connect to the six 3-pin headers at the rear that span the top of the main PCB. For power, you'll need a spare 4-pin molex connector but Lamptron has also thrown in a braided molex extender which is a nice touch.
