radiator fan direction

[actually_god]

ok so my life story first i built my computer into a case that i reticently and arbitrarily picked up off facebook market place for as little money as possible with the original goal of cheap old and crappy. said case was a lian li pc-70. being a man of history and culture i know this case to not be any of those things other than old. so instead of building in the most half ass way i could i put much more effort than planned in "doing it right" part of that effort was getting a second lian li case to take the side panel from as well as one of the bay covers. it ended up being more cost effective and faster than what was available when i was looking for parts.

second case is some random variation of the lian li pc-60 that i can not for the life of me identify because functionally its only difference is a change in the front cover. but yeah

 

i want to build another computer in this case and make it water cooled

why? fun i dont care about practicality (also i already own the case and most of the water cooling stuff from one of the other times i rebuilt my computer)

 

the guidelines for myself are the same ones i always have. 

-no visible modifications (stock looking)

-no ductape solutions (do it right)

 

i havent got any of the internals yet because i wasnt sure what i wanted to do. i will be wanting to water cool as much as i can reasonably so the cpu and graphics card for sure. if i can get a monoblock for the motherboard i probably will try and go that route. so slapping a 360mm radiator in it is no problem but i dont think one will be enough to cool a 4080/4090 and what ever dumb cpu i put in (i might just put a last gen card in to save money on the waterblock). so i am planning to slap two 360mm radiators in it. one in the bottom and the other basically where the psu usually goes ill 3d print up a bracket so i can mount it there that also acts as ducking to isolate its intake/outtake sides from each other. and then get an sfx power supply move it into the 5.25 bays (picture for reference). that will need a bracket printed as well and a c14-c13 internal cable to a panel mounted socket.

 

all easily printed or made. 

 

my only question/thought is what way to put the fans on the top radiator it will have the ability to let air in/out from the back where the power supply would have been. should i listen to my heat rises and part of my brain and point it so the heat goes out or should i listen to the part of my brain that says new air through the radiator only and let the little baby 80mm fans work overtime 

 

the fans i will more than likely use are the noctua nf-a12 i would put phanteks t30's in it but the radiators are dummy thicc ekwb quantum x360m (the 58mm ones so they will be 83mm thick with normal fans and dont need more help being giant and unruly plus i  still have to slap everything else into the case and would prefer not to struggle with that. (i think i am going to mount the pump/res where the 3.5in drives are. i cant outright remove that caddy because it holds the front covers on but it does come off with screws and i can cut it down so it isnt in the way).

 

my picture is of my case and not the other one. so there is two 80mm in the front and two 80mm in the back of the case that will be used (i feel like they will be there for mostly looks).

i didnt realize current gen motherboards with monoblocks limited me to the one i already have or basically the same one with an amd socket and i dont feel like limiting myself to $600+ asus boards which i dont really feel like spending for a computer that will actually spend most of its life playing blippy or some crap on youtube.

Why not try it in both directions?

 

Also, could you mount the T30s on top of the case fan ports so they help...?

wiring and lazy, so lazy i didnt think of this. but also might be hard/impossible to take the screws out without draining the system. after its built. i am leaning toward what ever that new top gaming cpu is (7800x3d) since this computer will likely replace my media computer attached to my tv so i wont do any productive work. how hot my 4090 currently gets and how hot a normal mid/high end cpu. unless something changed/i am overlooking something that is glaringly obvious because i am stoopid

t30's are thick the extra 5mm i loose is too much. there are no top fans in the case the top radiator will be made to blow out the back essentially so i loose a decent percentage of the volume i have for air flow if go t30 and honestly the difference between the t30 and the nf-a12 is just the past 2000 rpm performance since the noctuas dont go past 2000. i wouldnt want the t30's running that hard really anyways. its nice to have in some situations like on my mo-ra's where i can leverage the thermal transfer of them to maintain close to ambient under water temps heavy loads because i angry at my power bill and the only way i can find hippieness is pumping 500w into my cpu because i want make number go up. but generally i have those bad boys running at like 600ish rpms which is dead silent. noctuas will also match the 80mm noctuas i will likely put in it.

Are you undervolting?

 

So the case top has no exhaust ports?

no thats far too big brain for me. i think a delided 7800X3D wont need to be messed with too much

it has a single 80mm fan port which will not be considered (and shouldn't be)
