HELP setting case fans ?

garry dhaliwal · Mar 28, 2017

hi, i need help with my rig using this case
https://zebronics.com/products/cabinet-gaming/shield

currently m running idle cpu temp at 45* Celsius
room ambient temp 30* Celsius

in what directions should i place fans to maintain lowest temp possible including cpu cooler

garry dhaliwal :

Front and side case fans should be intake.
Top and rear case fans should be exhaust.

Heat rises, so exhaust should almost always be at the top of the case. The side panel being in take is for 2 reasons: cool the GPU a bit, and with only 1 front intake, you needed a second source of cool air.

How is it set up currently?

front - one intake
side -one out
top-one out
back - one out
also what about cpu cooler fans hyper x212 facing upwards m using one fan pulling out negative pressure should i use second fan on another side also ?

garry dhaliwal :

1 intake and 3 out (plus the PSU fan) means there's not enough intake of cool air.

Flip the side panel fan around as an intake, and while most people set the Hyper 212 blowing air out the back of the case with a single fan (I do this), blowing the hot air out the top like you've described is also okay. I wouldn't say you need to add another fan to the Hyper 212.

now that 140 mm fan is making noise sucking in the air buzzing noise :pt1cable:

no change in temp though

What is your CPU?

Agree with Kyle. Config should be

front = intake
side = intake
top = exhaust
back = exhaust

As for your CPU cooler. Note the image below:

with this setup temp is still same even rises 2 * Celsius

KyleADunn · Mar 28, 2017

garry dhaliwal :

Has it been this hot since you first installed the Hyper 212? Is your CPU overclocked? How long ago did you add the Hyper 212?

garry dhaliwal · Mar 28, 2017

(Hyper 212X ) no overclocking
installed 3-4 months ago
weather changed now during winter lowest temp was 33* Celsius

Susquehannock · Mar 28, 2017

Well, switch back then. General rule is go with whatever gives best temps. So many set ups with various fans and airflow rates that it is impossible to list a one size fits all recommendation.

In my case (pun intended) I get best temps (CPU, GPU, board sensors) with front, side, and back fan blowing in. And an empty 120mm "blow hole" out the top.

garry dhaliwal · Mar 29, 2017

how about connecting 2 120mm fans with each other pulling air out on top will it help ?

KyleADunn · Mar 29, 2017

garry dhaliwal :

Yes, putting an additional two 120mm fans as a top exhaust will help.

But that's a Hyper 212 X (newer version than regular!) so it's odd that you're getting those high temps. How confident are you in how you mounted it? Did you remove the plastic off the heatsink? Did you screw everything down in a cross-diagonal method? Not too loose or tight, just tight enough to where your hand couldn't turn anymore?
