Genuine question on CPU air cooler fans

[viggiesmalls92]

I am wondering whether changing the stock fan on the Cooler Master Hyper 212 EVO and replacing it with both an airflow fan and a static pressure fan would deliver better results. For example, using the airflow for push and the sp for pull. Would this deliver more cooling or would the reverse (sp push and af pull) be better? The fans i have in mind are the phanteks ph-f120mp and ph-f120xp.

A single fan in push will cool just as good as a single fan in pull. Running both push/pull will net you minuscule gains at high overclocks.

I've played around with push/pull on my H7 several times, using various combinations of Cryorig QF120 fans, Aerocool DS 120 fans and Corsair SP120 fans. The conclusion I frequently arrive at is that you only buy yourself a couple of degrees--at the absolute best--and the extra noise generally isn't worth it.

 

If you were going to push/pull, I'd think you want the same type of fan on each side. There's nothing behind a pull fan to necessitate all that pressure, but there's a ton of resistance in front from the heatsink itself.

Wouldn't a sp fan be better suited to a heatsink? SP fans are better for rads anyway right?

Pressure fans would tend to be better for heatsinks or fin arrays on rads, but the fans for push pull should be the same on both sides since it can potentially create turbulence and excessive noise with the different fans.

All fans have some degree of AF and SP. Most airflow oriented fans have sufficient SP for heatsinks and are better suited usually having lower noise.

the 212 evo isnt a thick enough heatsink to require push pull tbh... you wont see much gains

if the 212 evo isnt enough, i suggest you move to beefier coolers instead of adding another fan

Sometimes it's just about wanting your heatsink to look like it's about to take off

You know what they say about the size of a man's heatsink.

Thing is i am looking for a decent cpu cooler for overclocking (and hot ambient temps) yet i dont want something huge or oversized in my case. AIO's out of the question for me.

What's your CPU, what kind of case do you have, what are your ambient temps and how crazy of an overclock do you want to shoot for?

[viggiesmalls92]

i5-6400 currently OC at 4.4Ghz. I have the mastercase pro 5. I will be upgrading my CPU to the i7-6700K and hopefully overclocking that too but i would like to push my 6400 further. Highest amb temp in my room has been around 37-38 celcius so who knows how hot my case is.

That case is fairly roomy, a large air cooler or is capable of housing an AIO very easily especially if you want to do heavy overclocking.

Yeah but i would't want to look at my pc and see a huge cooler taking up the view. Probably something like the dark rock 3 is too big for my taste.

Then an AIO cooler would be a great option instead, not sure why you would not want that however.

i would totally agree... my view of my desktop is somewhat cooler blocked by my cooler, go for an AIO if you want extreme performance

could be anywhere that gets hot, they said highest not average, this just sounds like good forward planning

[viggiesmalls92]

South of spain so yeah hot temps and heatwaves are nasty. I mean i would get an aio but i dont have the funds to switch out my mobo or cpu if that ever failed and i would be annoyed if there was an air cooler with similar performance.

Well if your worried about leaking the likely hood is very low, if the pump were to fail the system would give a warning of the pump rpm or cause the system to shutdown if it gets too hot.

 

If you wanted something similar to a dual AIO cooler a large aircooler like the Dark Rock would be capable of that.

The Noctua DH-15, R1 Ultimate, Dark Rock Pro and that new Cooler Master triple sink thing that looks like something out of Back to the Future all offer AIO-type performance.
