If I was you I would go with the x62 kraken and just place it ontop with the included fans or even better some Noctua fans. I’m having the same issue now I have the NZXT 510elite case with the RGB fans in the front but they suck when paired with the radiator. Those RGB fans aren’t meant for that. You could do a push/pull config (the radiator has holes on both sides just attached the ones mounted on the front to the radiator and the ones that come included with the kraken on the back as pull). Also looked up your case and are you sure a 360 fits in the front? I see the bottom fan goes into the PSU shroud but you might not have enough space to do a push/pull config if that’s the case would check the clearance first before buying if you haven’t yet. Besides that installing it is pretty easy. I used this video

btw I didn’t know this when I bought mine but the krakens come with thermal paste already pre applied so you don’t need any.
