As for the GeminII, it should be adequate. Other potential solutions would be the Arctic Freezer 11 LP and Noctua NH-L9. The larger one, NH-L12 is just about too high, I think, since it's 66mm tall w/o top fan, and the CM Elite 120 has ~65mm of CPU HSF clearance.
I know that I can use a Molex to SATA adapter to power up the SATA device but the Molex connector is already used for the case fans should it still have enough power to run the HDD properly? I would use it for an optical drive only just to be safe.
Furthermore that Cooler Master 120 Advanced case can only handle up to 3 HDDs. If I add the 4th HDD I'll have to use the 5.25" bay which I'd like to avoid because I'll have to buy a 5.25" to 3.5" adapter plus there's no air flow at all in the 5.25" bay so it's not a good idea to put the HDD there as it'll run very hot.
The Arctic Freezer 11 LP and Noctua NH-L9 look nice but it seems they don't provide enough cooling. Right now I have my eyes on the new Thermalright AXP-100
, hope TPU will review it soon.
