all fans intake and no fan at rads?

[Font9876]

I wonder if it possible to have all fan intake suck all air into the case and make the air pressure to be positive in the case and install a radiator at the top of the case without fan and let the air pressure do its job exhaust at the top like 1 rear fan+3 front fan will this work cuz I wanna cut the cost on some thing like fans or just to be experimental

Well... if theres no fans on the rad it will likely just heat the loop until it overheats. I'd doubt it would work tbh

is it possible? yes

but it will run hot in a standard pc case

 

for good temps you would need to have really high pressure fans with no air leaks in the case or in the seams of the side panels or pcie slots 

and for that to be true you would need either a small case or really powerful and loud fans 

 

alternatively your cpu could be a low TDP unit, but then your theoretical cooling scenario is just way too expensive and overkill

I think it would be OK if you weren't doing rad but since you are then nooo way

if your case was perfectly air tight, then yes this would work. however, it is not, and the radiator is dense so has resistance to the air going through it. therefore, most likely a lot of the air will find another way out. 

just put some fans on your radiator and dont worry about it. if you really want to save the few $, then put the rad on your intake fans. 

 

in the scheme of things, fans are cheap, just get them.

u don't have to buy expensive fans with LEDs and imo cosmetic bs, get 2 standard black PSU fans for your rad and you're done.

even 1 front intake + 1 top exhaust will keep it cool, I've used one of my old rigs for years with only 2 fans and never had a single issue related to temps, it was mounted on one of those generic cases with psu on top

Even the ek vardar fans are just 20 bucks a fan us,I have seen crappy rgb fans sell for more then that.

Just buy noctuas and enjoy the silence and great temps. They're well worth the money

Terrible aesthetics though. Corsair ML series fans look better and run quieter, I would recommend those.

They have a fairly newish line I think they call redux? Same fans that made them hugely popular but without the extra accessories and in a monochrome look that I really like.

I respect Noctua as a company but the colors are just hideous. I can't ever look at any Noctua fan without seeing the brown and beige color.

Only if you have passive radiators or Chiller (you don't need radiators with a chiller). On normal radiators you need fans, without them the water temperature will just keeping raising with no way to properly cool it.

 

Due to density of radiators airflow alone will not make it through the radiator.
