Where to put fans?

[Doughnutnator]

Hi! I have the Corsair SPEC 02 case with this stuff inside:

- i5 4570 stock cooler

- G1 Gaming 970

I have 3 fans in total, 2 Corsair idon'tknowwhat and 1 Cooler Master Sickeflow. I have them configured like this:

- 2 front intake (Sickleflow and Corsair)

- 1 rear exhaust

But I see that the 2nd fan at the front doesn't do much because there's the drive cage, and I can't remove it.

So I don't know if it would be a little better to put it in the bottom, blowing air directly at the GPU. I have the front intakes filtered with some ghetto pantyhose, the bottom is filtered too but it's a crappy mesh that was included in the case, it kinda makes the job.

My PC isn't in the floor, is over a skateboard, because it's easier to move it when I want to clean it.

I also thought if it would be better to put the exhaust fan in the top instead of the rear, because heat rises...

What do you think guys?

Thanks in advance

Heat rising doesn't make any significant different inside of a case. Having the third fan as intake at the bottom would be best.

Unless you're temps are suffering I'd not bother. If they are go with your idea and move one to the bottom.

Why not filter the back fan and use that as intake, one front intake and then top exhaust (hopefully turbulence won't be too much of a problem), play around decide what works you.

So leave the exhaust at the rear, move one intake to the bottom? Sorry I didn't understood

That doesn't mess with the airflow?

I mean, the air would be like this

Maybe, I would suggest you test a variety of configurations and decide what works best for you

You should also keep in mind what direction your GPU fans blow. This can create unwanted turbulences and drafts.

Hmmm i will try today. Should I buy another fan or i'm fine with 3?

They blow air to the GPU heatsink, then it goes through the sides of the GPU and finally rises... That's bad?

Front intake, bottom intake, and rear exhaust.

Front intake, bottom intake, and rear exhaust.

Oh my god you are so right.

After a loop of Heaven the GPU used to sit at 68-70.

Now it's at 62-63°C max...

Thank you very much
