Radiator fans intake or exaust?

[DoctorX30]

Hello everyone i want to ask a noob question sorry but some said different opinions... I have the CoolerMaster master box 5 case and im thinking to put a radiator at the front panel the fans is going to be as intake or exaust?? please help, if the fans are intake all the heat are going in the case that will be a problem i guess, i dont know hot to put the fans :/

this is right way??? https://www.youtube.com/watch?v=7QQzqEKA8dg

now this is an inteke or exaust?

for front mounted radiators, intake is the better choice.

It means you're bringing cool air in over the rad. Yes the air will warm up a little coming through the rad, but it's not going to make things warm up too much, as long as you keep the airflow optimal with exhaust fans in the back/top.

In through the front/bottom, out through the back/top.

The other choice is to top mount the rad as an exhaust.

Thanks for the quick answer and i ask because i see some people have the fans from the other side of the radiator not at the front and i ask my self now that fans are intake or exaust

it depends which way you face the fans

some fans have an arrow on the side which shows which way the air flows.

it's not the side of the rad the fans are mounted on that makes them intake or exhaust, it's which way round the fans are mounted

example, if you have a fan facing so it's bringing air in, regardless if it's on the front or the back of the rad, it's still an intake

If it's on the front, it's a push setup. If it's on the back, it's a pull setup.

Push - pushing air through the rad
Pull - pulling air through the rad
Push/Pull - fans on both sides of the rad

hmm ok thanks that was very helpful so if i did it like the video?

 

[blockhead78]

yeah, looks like they did it as in intake in that vid

 

[DoctorX30]

so he is pulling the air from the rad

no you were correct the first time, it is indeed backward. it is sucking air from the inside and he has the rear fan sucking out as well. You can tell by which side the motor mount is on and by the shape of the blades in this case. Note how they are angled to be scooping air from that side. Almost all fans pull from the open side and exhaust on the side with the mount. There is a reason that vid has so many dislikes:

i'm not 100% sure, but it looks like he has the fans pulling air through the rad

 

[DoctorX30]

so then... what to i do?? just turn the fans or putt them from the other side of the rad? sorry im asking so many questions but i want to be sure

 

[DoctorX30]

Thats right way?

here are some pics of mine (dont mind the dust, it is very dusty here). In my case I was able to mount the fans as intake on the front in their normal spot then attach the rad to the back of it so it is forcing air through the rad from the front. My rear fan is an exhaust as normal. You can indeed mount the fans to the rear if you like, just make sure you have proper airflow in the case.

 

[DoctorX30]

mine has only 1 fan as exaust(rear) and 2 fans as intake on the front, so if i put the rad like you i guess it wont be a problem, my case is the coolermaster masterbox 5

Correct. On the image below you can see the front fans. note how you see the part where the motor is. I drew lines to indicate airflow path:

here is the site: http://www.coolermaster.com/case/mid-tower/masterbox-5-black/ if you scroll down you can see various configs they have with it. Note that on all of them the front fans are intake.

 

[DoctorX30]

hmmm i see and one last question and thanks again for the asnwers be good mine is just like this photo you post, if i put the fans on the front of the rad as an intake(always intake front) its ok? so from the side panel you can see the back of the rad

 

[SinxarKnights]

yeah you can do that if it is possible in your case.

 

[DoctorX30]

yes i think it's possible on CoolerMaster Masterbox 5
