As the other comment says, those fans for the case will work perfectly. For the BE14 v2 card I’m using the heatsink with fan from the BPI shop (I’m guessing yours is the one without the fan) - this one the heat sink is actually bigger than the card.
Mine didn’t come with a heat pad (like the one in the picture) so I simply put thermal paste. YMMV but mine It’s been working for several weeks without issues.
i installed them now with cable traps because the screws did not work that were shipped with the noctuas. need to get correct ones for the case and then see how i can use them on the fans.
