Push or Pull

Lil Rico

Wondering right now i have my AMD FX-6300 in an Push configuration with a Cooler master hyper T2 and was wondering which is better push or pull?

I prefer pull as it's easier to clean.

Pull is generally easier to clean, though I don't think there'll be much of a performance difference.

I like pull. I think there's more flow through the rad with less turbulence.

Not really really bothered about cleaning...

i prefer push because otherwise the cooler fan and my rear case fan are practically hugging, which kinda negates the purpose of one of them.

They're the same. Just do what looks and/or fits better

Pushing is generally more turbulent, but pulling gives greater flow. Both are effective, but it's generally been shown in single fan configurations on CPU heatsinks that pushing is more effective. Unless you have a custom shroud, then pulling would be more effective. Unless you have spacers, then a push/pull configuration would be more effective. Unless you have an unlimited supply of liquid nitrogen, in which case no fans would be more effective. Unless...

Push. Less hot gpu air.

Wat? He didn't ask intake/exhaust, he asked push/pull. And the answer is at the airflow levels of the fans in question it doesn't significantly matter from a performance perspective. You might be putting a slightly larger load on the fans in push configuration. Now, when moving serious amounts of air in HVAC or automotive applications, pull is better.

 

 

Addendum - As for intake/exhaust, if you have a blower style card it doesn't really matter. If you have an open shroud card however intake is 7-10 degrees cooler.

I know exactly what he asked.

2nd thread where you bring this up. GPU being hot has minimal effect on CPU cooling. It would require GPU backplate being super hot to radiate that much heat that CPU heatsink would heat up too much for fans to handle.

Its theoretical. And i bring things up as often as i like.

GPU backplate temp has much more effect on fan orientation(parallel/perpendicular) than push/pull though.

True. But in my own testing, temps went 3C down horizontal vs vertical. Even using same paste.

Yeah, that's my point. I can't think of a single significant reason why push would be superior regarding GPU air. Any theoretical but insignificant gains would be more than offset by the temperature of the fan motor.
