depends on your budget and preference on brand
i'm sure that should give you a start.
considering you have a gaming motherboard but a locked i5 is interesting. but that makes me think you're budget conscious. I suppose you want a low level of noise, so cryorig H7 at $35, noctua nh-d15s at $85, and cryorig a80 at $125 are pretty good.
p.s. if you need a recommendation, specify your budget next time. cheers
