550D new fans

spluff · 21 Apr 2016 at 09:56

Currently I have a 550D with the following setup:-

Front: Noctua NF-P12 120mm * 2
Bottom: Noctua NF-P14 FLX
Back: Noctua NF-P14 FLX

I have tried using one of the old Corsair 120mm fans and the gpu runs better...

I am thinking of getting:-

NF-A14 PWM for the lower side panel - exhaust

Also thinking of getting another NF-A14 PWM for one of the two top fan locations...

Would you recommend the fan exhaust above the cpu OR exhaust/intake closer to the top front of the case..

Any thoughts please

Heat rises ....

I have put two exhaust fans at the top of my case to pull the heat out of my case so if you have the space to fit two then put two in, you can they turn the rest of your fans into intakes this will increase your internal air pressure and also help to move air from the bottom of your system to the top and this should help with motherboard and component cooling as well.

This is how my system is set up.

Also your 980Ti blows air down onto the fins so if you can pull colder air into your case from the side this will also help with GPU cooling.

Cheers Anthony

That will mean 3 extra fans and the cost

(total of 7 fans lol)

was thinking if you put the exhaust at top front wouldn't that just pull the coldish air straight up through it instead of being directed towards the back and rear?

That's why I thought just having the rear top fan so that we have 2 exhausts at the rear top of the case and 4 intakes (2 front 1 bottom and 1 side)

What do you think

Only the fans at the top/roof of your case should be exhaust and all the other ones intakes (2 front 1 bottom and 1 side)

I wish people would stop saying this is relation to modern day pc cases.

The theory is you have enough airflow for it grab any hot air and drag it along and out the exhausts.

Passive cooling is so slow that it should never happen in a modern day case.

If you are in a situation that passive cooling is actually cooling your case and the air is so warm that it can start to "Rise" then you have a dead air spot and thus a problem as in that area could have localised over heating.

Between the case fans and the GPU fans there should be very little still air.

Sorry to jump on your post Anthony, bit of a pet hate of mine apologises.
