The importance of High static pressure in push/pull? Help please

GiraffePencils · 22 Mar 2013 at 22:11

Hey, I understand the point of having high static pressure pushing against the rad, but in a push/pull config do the fans which are pulling matter as much?

I mean, they're just getting the air out of the way, do they need to have high static pressure or can they me any reasonable fan?

This isn't quite exactly what you're after but when I was doing research for my build I found this which is a comparison of push/pull/push+pull which gives a nice overview of the difference the fan combinations make.

thanks, that is pretty helpful

Just noticed your sig, nice on the 920, I've got the same myself, ramped the bad boy up to 4.1 Ghz

Hi, l have used fans set to- pull / push

ull / pull and found theres only about 1'c using the same fans[not pwm] all round, so have set my low rpm fans on my rad to pull. So static pressure pushing against the rad does not come into effect, as l'm pulling the air through the rad, as l find this does not fill the rad up with dust as quick, rad mounted externally.

this is just the i7 920 club

cool, thanks for the advice.
nice to hear numbers in 'c I have when people argue on what's best and they're arguing 0.1 of a degree

I am happy to say my i7 has served me well for over 4 years now. Once OcUK finally get all my parts in stock and my order ships i'm going to be doing a WC build of my own so with any luck i'll be pushing past the 4Ghz marker myself

LoL, yes them were the days will l break the 4ghz barrior, now its 4.5ghz then the magic 5ghz, but 24/7 stable.

To run at 4.3ghz l need 1.35Vc in the Bios it will run 24/7 but temps are just under 70'c, a little to hot for me and its worth adding 1.
