Hi fellas,

Just going to start rebuilding my new loop later today, and have been pondering to which way to setup my fans.

Would I be correct in thinking positive pressure is good? :confused:

Take a look at my proposed setup below.

Bear in mind, I plan on having 1x 360mm in the top, 1x 240mm in the bottom, and another 240mm on the front. All radiators will be in push/pull.

If you have any suggestions, please feel free to let me know. :)
 
I think you'd be better off pulling in at top and exhausting at the back. Air from the front gets exhausted out of the bottom fans and air from the top out of the back / circled around to the bottom
 
Positive pressure is good (keeps the dust out), but the front and bottom should be intakes and the top and rear should be exhausts to take advantage of warm air's natural tendency to rise. Run the intake fans at a slightly higher speed than the exhausts to ensure positive pressure.

I was going to suggest this but wasn't sure how well the bottom would intake as I don't know the ground clearance :o
 
^That is absolutely the best way to do it. Cool air in at the front and bottom, hot air out at the top and rear. If you exhaust out the bottom like the picture illustrates that warm air is going to come back in via the front intake and psu intake. If you are worried about dust buy some dust filters.
 
I'd flip the rear round, grab a magnetic dust filter, and have it as an intake too mate, and just have the roof as as exhaust.
