Weird... I emailed them about it and they said they don't have any...
They said that to me, but when I said I needed to fit a noctua thin than, they suddenly had them.
You have to max sure you ask for the x25 ones, if you ask for the x15 super thin fans they will not help you, you can bend them to make them work with the x15 ones, although annoying.

long as your happy, yeah ive got to 15mm noctua 120’s from my DA2 build that im gonna fit below the card as well, but i have ordered some taller feet for my case, so i can get a bit more air from below, but also if i cannot fit the fans below the gpu i might fit them underneath the case, but hopefully they will be ok,
