Pull or push

[tangoseal]

After all these years I still can't figure out what is best.

Pushing or pulling through a radiator. In this case assume you can't do both due to case space.

just depends on how easy you want it to be to clean(pull keps dust on the "outside" of rad) and looks(motor supports visible). i didn't see any difference in performance until i went push+pull.

It really depends on the placement of your radiator and the air flow of the case. If you don't have much airflow going through your case, then most likely you want to push air through the radiator. If you have a lot of airflow going through your case, then it may be easier just to pull through the radiator.

What you don't really want to do is pull stale hot air from inside your case through your radiator.

This is very informative

^perfectly shows what i meant about cleanability.
jayzs got some numbers to help too.

Cleanliness is a good point, that is one of the reasons my current setup is just a pull setup. Also in that Linus Tech video, he made a good point about the type of fans. Another reason I switched from my previous push/pull to just pull is that I have better fans now.

I have ran them both ways, and didn't see an appreciative difference in temps, but my setup is closest to a test bench slung under a desk. Pull makes it easier for me to run a vacuum over to clean the one side

You forgot

*Either - it really does not make a concerning difference.

Always go push, proven over and over to outcool pull by 1c.

Best = Both. All my rads are push AND pull... because over-engineering is [H].

Top rad (480):

Rear rad (360):

love that double-stacked fan for the rad "bracket".

imo doesn't matter, I just setup my case so I have slightly positive pressure

Note that its probably a cheap fan cut out and not a cut out Typhoon as its two different fan casings. Cutting out a GT for a shroud is heresy!

Ya, I used a sacrificial failed Scythe Ultra Kaze fan which I gutted. Works surprisingly well as a rad mount. I'd never do that to a Typhoon though... If one ever failed on me (none ever has and it's been a good 5+ years now), I'd give it full honors and bury it in the back yard.

 

[pendragon1]

i assumed that. everyone knows(or should) that you don't double stack working fans.
gotta give it a little tombstone too!

I just went to home depot and bought some aluminum stock and matte black krylon. Gonna make my own 4x120 swiftech external rad bracket to sit behind my case. I didn't realize how much heat 2x 1080tis output plus today I'm throwing my 1950x in loop. That's gonna be a kilowatt of dissipation easy when everything's wide open.

You should throw a 1080 rad or larger at it. I sold one of these couple months ago. Still have one left seen below cooling my server. I used to run two of these with two 480s cooling quad 290x lightnings and 3930 back in the day when I benched a lot.

Well at that size I might as well just go and hook a Diesel truck radiator up and use it lol...

Its not that big lol. I've run over 3000mm of rad before, now that was large. Besides that, its easy to lump a bunch of high wattage parts together but its a whole other thing to try and cool it.
