Are these good fans for a push/pull setup on a cooler master heatsink?

The cooler master fan is 600-2000 rpm. These StarTech are 800-2200 rpm. It will have a slight advantage, as the min speed will be higher. To mount in a push-pull you will need a PWM splitter power lead. Will your motherboard CPU fan header supply the amperage increase?

What is the size of the Startech FAN12025PWM case fan?

The size of the StarTech FAN12025PWM case fan is 120mm x 120mm x 25mm.

The PWM Y splitter looks like it has a 4 pin PWM and a regular 4 pin molex. Does it control two PWM fans or one PWM and one non PWM fan?

I do not believe this fan is equipped with a molex connector. I believe it is a 4 pin PWM connector coming off of the fan, and has a y-splitter that can have two 4 or 3 pin fans connected to it (of coarse 4 pin is required for PWM control.)

What is the warranty?

Hello JJ. In the Description tab for the fan it says: Backed by a StarTech 2-year warranty and free lifetime technical support. That's a good long warranty for a fan. The Specifications tab says 1 year parts and 1 year labor. Still that's a long time for a fan.
