Stacking thermal pads on a waterblock a bad idea?

post #1 of 3
Thread Starter 
Hello, I currently have a GTX 480 water block and will be getting a GTX 580 from a friend. I will be using my old Koolance VID-NX480 on the GTX 580 because the PCB design is nearly the same.

The problem I have is that the GTX 480 has taller VRMs compared to the GTX 580, therefore needing thicker thermal pads. I already bought some .5 mm polyfuji thermal pads and cut them up, would it be the same if I stacked the thermal pads compared to buying new 1 mm pads?

Not really a bad idea as long as they don't slide off.

They are meant to be pretty close, so it's might not be too much of a problem, but the higher they are, you temps will increase greatly.
