Push/pull

Just to make sure, the only way you chose the airflow direction in your case is by turning the fans round right?

And is it better to have the flow going from the front to the back

cheers

front intake rear exhaust is the right way

and your right on the only way of changing the airflow is turning the fans around.

Ok, thanks.

I turned the back exhaust fan around to blow cool over the rad, 'nother option, didn't try it the other way so don't know if it does any difference lol

So you had two fans pulling air in?

tried that and about 3 deg hotter in my case :/

You have to experiment as some cases are a bit odd.

I have a fan at the top rear and on top of the case extracting air and a fan on the side at the bottom bringing in air. After various testing this worked best for me. Another tip is to make sure your PC has plenty of clear space round it to let the cool air in and hot air out. If you put in into a small tight space you just end up circulating hot air.

Hope that helps

as above,
I find any front or side fans are best as intakes.
Any rear or top fans as exhausts.

This is what I'm worried about! I'm not going to have side fans because it will be within an enclosure (two side panels on a desk).

two fans on the H100 pushing through the rad then out the top of the case, the 120mm fan on the back (normally exhaust) as intake, which pushes cool air straight in and out through the rad,
then a 200mm fan on the front as intake

its also pretty chilli in my PC room, no radiators on!! (until summer, then its a heat trap lol)
