Closed loop question bugging me

Memhorder · Jan 25, 2014

Hi. I have a 240mm rad that will be top mounted. Something that bugs me is that Corsair say's to have fans outside pushing air into the case. I want to have them exhausting so that there would be 3 exhaust 3 intake. If the fans on the rad are intake then that would defeat the purpose of having the case with dust filters on front and bottom. Plus having to clean the dust out of the rad. My fx-9370 will be arriving soon and as you know it is a furnace. My question is how much hotter if at all would an exhaust setup be? The upper rear fan will be at max all the time as it is 3 pin

You have it figured correctly , have the radiator fans blowing out as exhaust along with the rear fan. The front and bottom will be intake and have the filters.

Corsair is just saying to have intake fans along with exhaust fans.

my guess is about 2-3degrees. Nothing to worry about. a 240 rad will easily keep your cpu nice and cool

the only problem flipping the fans is you'll be pulling the warm air from your PC through the radiator. That's the only downside and you'll keep those filters working.

bigwoofer , why did you select the solution ? The thread has only been active for 10 min, much too soon for a solution.

Memhorder · Jan 25, 2014

Alright. That is a piece of mind. Wouldn't an intake essentially just warm the inside of your case? If you have a Rad how often do you have to clean the dust even with the filters. I mean is there still a little build up?

inzone · Jan 25, 2014

There can be some dust build up since a case is not air tight but it will take longer since you have filters on the intake fans. Probably clean it out once a year.

If you set the fans on the radiator to intake then it would warm the inside of the case.

How would he select the solution?

inzone · Jan 25, 2014

By selecting the green " Pick as the Solution " button.

Memhorder · Jan 25, 2014

That's weird because I'm OP and it seems I can still pick the solution

Thanks appreciated. Now I can sleep at night

inzone · Jan 25, 2014

You could still select the solution because I de-selected the solution that bigwoofer did since it was too soon and you had not replied to any of the posts yet.

inzone :

I had no idea there's a time minimum on solutions, and I still believe it is the accurate solution.
- put the filters to work (DUST is a component killer)
- a little higher temp air hitting the 240mm radiator is less evil than dust buildup

A good rule of thumb is to try to even up the inbound and outbound CFM, for me it's just the quieter sound I want, but for others they may be interested in efficiency.

A lot of people tend not to go into a thread that has a solution so it lessens the chance for further posts , besides the OP had not responded to any of the posts and he should at least have the chance to select his own solution. Giving everyone with 5 best answers or more the ability to select the Solution was meant to have more threads with a Solution since some would just not select a Solution and abandon the thread. There is no time minimum but we generally like to see a thread go for a day before a solution is chosen to give others a chance to respond.

Got it inzone, thank you for the explanation. Lesson learned!
