Do I need two radiators?

[Starfox2819]

In my loop I want to cool a graphics card and the cpu and I am getting 420mm rad (Three 140mm fans) that is 55mm. Should I get a 240mm Rad also or will I be fine. I will be doing a little overclocking but not extreme overclocking.

420mm long 55m thick would be perfectly adequate. A second radiator wouldn't go amiss though, especially since it would be easier to add a second graphics card in the future than adding both a graphics card and radiator.

A single 420mm rad is fine for cooling a cpu and a single gpu. You only needed the second rad if you were to cool a second gpu, as well.

[Enderman]

no, one is more than enough

also before you watercool make sure that you will be happy with your computer for a while changing anything is a huge pain with watercooling

So I am going to get a Phanteks Enthoo luxe an If I place a 240mm rad in the front will there be any places where I can but hard drives.

Dazmode said a good rule of thumb is one fan per component for a 50-60mm thick rad (the motherboard's vrm, chipset, ram etc counting as 1)

You could buy a bracket that allows for HDD mounting in the 5.25" front bay. Otherwise, there is no other spot for HDD mounting. There are SSD brackets on the back of the motherboard tray, but an HDD wont fit.

You could place your drives under the powersupply cover.

am using one of those, didnt know I had it until I went rooting through some boxes, its been a life saver for sure.

Really? That is actually kinda cool. Thumbs up to Phanteks since they included that.

[InsaneNL]

They don't include it but there is enough space to put them if you make a something to mount it. And thanks to the cover you won't see how it is mounted
