Please help me pick a good Y-connector

Hey guys,

I'm planning to get a coolermaster Hyper 212 evo fan, and some suggested that I attach two LED fans to it and hook both of them up to my CPU fan port by using a Y-connector like this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16812123298

However, does anyone know if this cable is good? What has me concerned is one of the reviews, who said:

"Pros: Sleeves look nice.

Cons: See the four wires at all three connectors? (My bad, I should have noticed this before I ordered one of these) A proper PWM Y cable doesn't have a tach wire at both Y ends - only one of them. This one has them at both ends, and unless you're prepared to cut or remove that wire from one of the connectors it will confuse your motherboard into giving you incorrect RPM readings.

Other Thoughts: With all the negative feedback regarding OKGear products, it is truly amazing that Newegg continues to carry them."

Is this one good, or should I get another? Also, what did he mean by that thing about the pins?

Thanks guys :)

This one looks just as good (and cheaper!):

For the pin thing, this is how it is:

A PWM fan has 4 pins, one for PWM, one for RPM, and two for power. A splitter should only have an RPM sensor on one of the connectors. If you have the pin on both, the motherboard will think the fans are running at twice the RPM than they actually are since signals from both fans are being sent.

Apparently this isn't the case though, as another reviewer noted no problem.
