can i fit the XSPC D5 Photon 270 to noctis 450?

I don't see why not, you can always make it a spacing priority.

You should be able to fit 2 280mm or 2 360mm radiators.

You haven't described what it is you are cooling or any other system specs. I would say that dual 360mm would be enough to cool a CPU and 3 or 4 GPUs.
 


only 1 gpu+cpu
also can i fit dual 380mm without issues ?
 

i found really good deal
dual 360 for the price of one
 


thats fair enough then--i still think 2 x 360mm and the D5 photon may be tricky

do you already have the pc case?
 


no
 


how about D5 Photon 170?
 
You could probably make due with a single 280mm radiator for a single GPU and CPU. Just for symmetry 2x280mm would be okay, though very much overkill. The fans would be larger and hopefully a little quieter.

i7-4770k @ 4.3Ghz here with two GTX980. 1x280x25mm and 1x120x45mm is all I have. About 600W capacity.

 


bit smaller but still may be tight its quite wide the res

if you had hands on the case it would be much easier for you to figure out what would fit where

maybe some one with that case may post to help out

or may be a you tube video of some one with a loop in it

i cant say definitely yes you can fit 2 x360mm and the D5 photon

but cant say definitely no either
 


so that it mean would fit right?
also can i have hdds
