Motherboard VRM thermal pad replacing

[sapphirethunder]

I was thinking of replacing the thermal pads under my Asus M5A99X EVO R2.0's VRM heatsinks and was wondering what thickness would possibly be the most fitting: 0.5mm, 1mm or 1.5mm (though 1.5 probably is for sure too thick)

And another question is that what would be a good brand?

 

The shop I'm looking at, has Phobya, Alphacool and Arctic Cooling.

 

And final question: would it actually be worth the while?

 

 

Also, any installation/replacing tips are welcome.

Pick the thickest one so you don't put too small one

Are the thermal pads flexible enough so they can fit even if they are a bit thicker than original?

Of course they can

Alright, + I just noticed that the lock mechanism on the heatsinks has spring on them, so they simply will get pushed back by the needed amount.
