Radiator Fan Direction

[Phunky Phish]

I am thinking of upgrading my current rig and software.
Fancy going to Vista and dumping the SLI. Have decided a P35 board and 8800 GTS 640mb with an extra 2gb ram should be sweet!

But I will have to rip out my water loop so thinking its time for some changes!

1) Lap the CPU. I know I am not getting good contact!
2) Ditch the res ontop of the DDC as its pants and fit a swiftech micro res
3) Get a Lian-Li V2000B case so I have room to play! The Lexa's looks sweet, but its cramped!
4) Drop the water cooling on the gfx. I spent £100+ to cool these puppies and now they are obsolete!
5) ditch the 120.2 & 120.1 rad setup and go for a PA120.2 rad. Much better than my rads me thinks!?

So, I will be lining the new case with akasa sound damping matting and will place the rad at the bottom of the case.

Is it best to put the rad at the bottom, with a pair of Noctua NF-S12 1200RPM blowing air through them and out the bottom
OR
place the fans on the bottom and rad on top so they suck air through the rad and out the bottom?

I run a fan controller so will slow the fans with this. Or would it be better to ditch this also and just go for the 800rpms?

Stay phunky

PS. I have searched the forums and I know this has been asked before, but do you think I could find it?!!

It's probably just dogma, but I've never liked seeing fans blowing hot air downwards. Just seems wrong somehow. "Hot air rises" and all that.

hi Phunky,are you any good with a dremel? the reason i asked is because i have the lian-li 2000B and this is what i did http://forums.overclockers.co.uk/showthread.php?t=17185358&page=20&pp=30
i have the s-flex 1600 fans @ 7v(modded a molex connector) and ditched my controllers as i didnt want to spoil the look of the case.in my last case i had 2 push/2 pull and found this the best method for my set up,so i wanted to do the same.So i replaced the stock Lian-li fan at the front with a papst(silent version),And fixed my rad to this with a kama bay in the bottom 3 bays.Doing this gave me my 2 push/2 pull config that i knew cooled my rig nice.hope the pics in the above link help you out m8 ....oh ,Keep Phunkin
