I am confused if my fan positions are correct or not, I want to seek an advice about this.

I currently have a mid tower case Thermaltake urban S31 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

My current fan set ups are:

Top: 2x 120mm exhaust fan
Rear: 1x 120mm intake fan with a radiator of Corsair H60
Front: 2x 120mm intake fan
Bottom: 1x 120mm intake fan

are these correct? or do i have to change something. Thanks in advance.

Hello Marc,

You got to much of Intake and not enough of exhaust. I would change it to something like this.


Top: Exhaust
Rear: Exhaust
Front: Intake
Bottom: Intake

This will give you a positive airflow flow through the case. Which is something that you don't have at this time.

What temps are you getting right now?

Processor: 35degrees on idle, 50degrees on full load
Board: 40 degrees on idle, 45-47 full load
GPU: 41degrees on idle, 50-55degrees full load

so should i make my rear with a radiator as exhaust?
won't it not be able to push more colder air for my CPU?

Those are some nice temps. I am guessing that your case is maybe next to a wall or something like that.

If so, Your not pull that cool of air from the back side of the case. Redoing the setup, will pull in and exhaust the air in a more positive manner and it should cool down the system more.

Your very much welcome. Have fun gaming.
