Is push much better than pull

[danial9]

I am getting nzxt  s340 elite with h115i corsair but on front of case I have to put fans first and then radiator toward inside.  I can pull air out   or I can push air in . Whih one is better in term of temps

Push is superior in terms of temperatures usually, but I don't think you'll see a big difference between the two.

No, it's pretty much identical.

 

The only difference is with push+pull which can perform better at lower rpms or on thicker rads.

Depending on the fan or radiator or combination of the two, you might see 1-2C difference in temps, PULL is easier to clean up, just blow some air through it, for PUSH you have to take the fan off to clean it.

basically it pushes/pulls same amount of air into the rad so its pretty much identical, even though on thicker rads push can be better most times, although pull when fans are towords the case attracks less dust into the case..

"Pretty much identical" leaves room for it to be better(even if it's slightly. Bear in mind that the OP only asked for what's better between the two), which seems to be the general consensus.

No, it's identical, the "pretty much" is margin of error.

You can find plenty of tests that demonstrate it.

It also doesn't make any sense for it to be different according to the laws of physics and how fans work.

It depend on the fan frame and RPM.

If you go past 2000RPM or have a fan frame that dont sit flush against the radiator, so will pull be better.

The first is a case of the radiator not being able to let air through fast enough and you get splash back, the other is because air escape on the side of the frame.

Both are avoided with pull.

you don't have to put the fans first and then the radiator, you can have the fans on w/e side you want them.

i would use the fans on the radiator as intake, push or pull is up to you, you won't notice a huge temp difference.

In your case with the rad mounted in front with the fans outboard, you will want those fans pushing. Always intake at the front unless you smoke with an ashtray in front of your PC. Intake should always be in front with exhaust rear and mounted high.

You can mount the radiator to the inside of the case, with the fans on the inside of the rad like i did. This make cleanup easy, as there are no fans in the way. simply use a paint brush and vacuum to remove dust and pet hair.

 

 

[Why do I even do this]

Isn't pull superior ?

Since you won't get dust trapped inbetween the radiator and the fan ? =Easier cleaning ?

Also without a shroud won't you get a blind spot on the rad in pull ?

The case I have I can't fit 280mm like how u have it . I need to fit fans first and then radiator. So my arrangement is switched.  I can pull out air or I can push air into case

Push if you must. Is there room between the case and fascia (front panel) for fans? Unless the fans and rad hit the mobo, I see no reason why cant have it like mine. Mine was really only specced for a 240, I managed to fir a 280.

It makes basically no difference. 

 

However, you're not "stuck" with either... because regardless of which side you mount the fans on you can always remove the fans and flip them over.
