I'm gonna start out with the stock-fan. But IF it makes to much noise I might go for a Scythe "Big Shuriken".
Not even sure it's gonna fit (have to make some measurements first) but I have been in dialogue with a guy who has this setup:
- OrigenAE M10
- Zotac GF9300-G-E
- Scythe Big Shuriken
He had to remove the 60mm case fan, and move one of the circuit-boards in the M10-case.
Comparing the Zotac and Intel (DH57JG) boards I can see that the CPU-sockets are in different locations, so it might fit even better in the Intel-board.
It will be a tight fit and it might block the PCIe slot but... If I don't need that slot (and the stock is too loud) I'll probably give it a try
