I am installing my first GPU full cover block and got a question regarding thermal pad coverage. After removing original cooler from my card I couldn't help, but notice how much less thermal pads there are in alphacool cooler comparing to the stock cooler. I then went and checked other full cover GPU blocks and they have thermal pads for all elements original cooler had.
Why does Alphacool block miss so many thermal pads? I have some spare pads from original cooler is it safe to use them or I should stick to instructions?
Just for comparison, here is Alphacool pad installation manual:

And here is Heatkiller:
