Ne zaboravi ni Kraken G10 (barem već ima vent za hlađenje VRM-a).

Međutim:

Compatibility

- H50 (CW-9060006-WW only)

* Some variation in die thickness and height may cause issues with screws being too short to install on some AMD 290-based cards.

* Do NOT force the G10 to fit if your card is too thick, contact support for a revised screw set.

Ne znam koju to točno R9 290-tku misliš počastit ali ako imaš mista u kejsu prodaj to vodeno i nadodaj novce koje si mislija potrošit na taj "adapter" i imaš:

4. http://www.prolimatech.com/en/produc...d=2565#showtab

Stavka 1. je trenutno najbolja jer već ima ventove, sigurnu dobavljivost i vrlo vjerojatno najnižu cijenu:
