480 mm intake radiator low/med/high fpi?

[ahimoth]

Hi guys,

I'm looking at picking up a second radiator for my 900D. I was wondering which do you think would be the best option. I currently have a XT45 480 from alphacool in the roof and will run push pull with Nf-F12's but I was wondering maybe getting a high/medium FPI radiator and running some of those new high RPM noctua fans on it so I have faster fans on the bottom sucking air into the case and slower ones pushing the air out.

Thoughts?

Push/pull will add little. The main thing is how concerned are you with noise as the more FPI, the more powerful the fans and the more noise generated.

To be honest I really don't see the point of watercooling and then using high RPM fans especially where radiator space is not that limited like in a 900D. Keep it big, low and slow but moreover make it beautiful.

Without knowing what you are cooling, what you currently have and what you are trying to improve/achieve it's difficult to make a sensible remark about the particulars of what you should do. But me personally I would be going for the biggest, fattest, lowest density rad possible and keeping everything nice and slow. Also from an aesthetic standpoint i'd want matched brand/product line of radiators and fans throughout ie all Alphacool NexXxos and NF-F12's.

I think maybe he is going for a positive case pressure, faster (more air in) and slower air out.

I hadn't ever really considered that in the 900D, most of the big builds seem to run a 480 and a 240 passing through the bottom completely isolated by a mid-plate and then a 480 in the roof and I assume intake fans at the front although they are rarely visible. It seems like too big of an open case to develop any significant sub/supra ambient pressure and it's so well filtered would it really matter anyway. Besides i'd happily dust something a little more frequently if it meant not running loud fans through a high density radiator. The whole point in the case is to have overkill radiator space and hence no need to run fast fans. If two low RPM 480's aren't going to dissipate enough heat then smack in two more 240's would be my game plan before speeding things up
