Hello all, I am still new to cooling and had a few questions.
1. Are corsairs af120 and sp120 silent edition fans PWM and if not can I still control there speed on a fan controller like the one listed in the title.

2. (restated from title) Are pwm fans needed for use with a fan controller (NZXT sentry 3 fan controller)?

3. What exactly is a pwm fan other than it has a 4 pin fan cable.

4. When daisy chaining fans I have a total of 6 fans in a case (900d) and seeing as the sentry only has 5 fan heads I want to control both my push and pull fans on my cpu's radiatior via one channel are there any y splitters that I should watch out for that dont work fully?

No, in fact you need NON-PWM fans for a controller like that.

NEVER connect the radiator fans to the fan controller. You NEED to have the connected to the motherboard with the CPU-FAN port.

On another thread I was told that I could use the fan controller for my radiator fans as long as I "placed the temperature sensor inside of the radiator? Which I don't quite understand how that can be done."

Update I chacked the amazon page again and found my primary answer.

No, you NEED to connect the radiator fans to the CPU header on the mobo.

Ok well seeing as my radiator will be in push - pull then I would need to use a y spliter correct?

If you have more than one fan, yes you need a PWM splitter to connect both fans to the motherboard.
