the power supply doesn't come with any kind of adapters for anything, just the cable connections to supply power, as its name would imply
i have that same set of fans actually, and as they come, they don't have the right connection to be powered directly from the psu, they use a 3-pin connection that you would usually hook up to the mobo.
it looks like that mobo has two 3-pin connections available, but you'd still need two more for the other two fans.
what you could do is buy two of these adapters
Newegg.com - APEVIA Power 4 PIN Adapter TO 3 PIN Fan Adapter Model CVT43
which will let you power the 3-pin fans from the 4-pin molex connections from the psu.
or instead get a fan controller (no adapters needed) and you could power all 4 fans directly from the power supply, plus you can manually control their rpm speed from the outside of your case, just turn the knob.
Newegg.com - Scythe KQ01-BK-3.5 "KAZE Q" Fan Controller
i have this one and it does its job well.
that heatsink will do. what you wanna do is get a push/pull setup, where one fan blows (pushes) air into it, and one fan sucks (pulls) air away from it.
this should explain it a bit more.

when you do this you want it to face the back of your case.
