Question

computer case fan positioning

Jun 10, 2018 9:12PM PDT
Here is a diagram of my current setup of fans.

1+2 are 140mm 97 CFM fans

3, 5 and 6 are stock fans, probably around 60 cfm

4 is a newer 120mm floor fan with 95 cfm

I would like to know if its a good idea to move fan 4 to spot 3 or 6, or leave it where it is.. currently the airflow is going straight up almost evenly, but if I switch the fans positions it can create a negative airflow trying to let more hot air to escape or change the direction but allow more cool air on my GPU

final note that fan 3 barely feels like it does anything compared to fans 1 and 2

thanks in advance, scientists

Keep it simple.

One fan at the bottom and one fan at the top.....then you test.

If things are starting to get a little toasty then you add fans and test.

not really the info i was looking for

adding fans 1 by 1 is not what I am looking for, what I am trying to figure out is if MOVING a certain, stronger fan makes sense

Of course not

Your looking to build a complex setup right from the start when it may not be needed.

Good luck.

not sure where your assumptions come from

I'm literally trying to figure out if its better to move one fan around, because the fan that im going to move requires the most effort to change location, its actually easier to just buy a new fan but then i'll have a fan lying around while I could be buying other stuff

The method is to set it up, put in your temp sensor and measure.

Make the change, then measure again.

Only those very new disagree.
