BOTH fans need to be replaced on this thing, they are LOUD AS HELL, they are at least 35-40 decibel a piece, its absolutely terrible.

Can someone recommend some heatsinks for both of them? im not sure which ones to get. I would prefer them to be fanless because any fan at that size is way too loud.
