As title, which direction should the airflow be in the PC tower?
All coolers pointing in? Or out? Or ...?

Thanks for any help

the cooler at the front of your case should suck air in, then at the back the cooler sucks the air out, if you have a fan on the side then this should suck air in, if you have a fan on the top then this sucks out, hope this helps, this how i run mine, i have a q9400 overclocked to 3.6 and it runs at 30c, the internal case temp is 35c

Has the price fallen off ?


Nice PSU though.

what cpu cooler are you using, also which cpu, also depends on what case you have, i have a arctic cooling case so i have a 12cm fan on front "in" 12cm back "out", top is a 8cm "out", side panel is two 8cm, one "out " and one "in", on the other side i have a 8cm "out" which pulls the heat away from the four hard drives, on my cpu i have thecoolingshop.com/pro…tml which pushes all the heat from the case directly to the rear fan and out, all my fans are on max, im not bothered by the noise as i use headphones the logotech G35 also well worth the money.

Apparently fans mounted on the side of the case often disrupt the airflow, especially around the GPU and cause the temperature to rise. Don't suppose anyone's tested it?

that may depend on what gpu you have, it may have made a difference on the older cards, but now most cards are almost sealed with just the fan showing to take in air, i have two side fans next to each other, one in one out, i put them there to sopt to much heat rising, they help more when the heating is on and i'm playing games, which is when the system is at its hotest

The standard is to have fans at the front of the case sucking air in and fans at the back blowing it out again. Don't have the airflow going in more than one direction with a fan on the top etc because it disrupts the airflow. To get the most efficient cooling you need the air flowing in 1 direction and as fast as possible.

You have a problem there, around your heatsink area, both of your fans in that corner are sucking air AWAY from the heatsink.

i agree get your self a better heatsink and fan, take a look at the arctic freezer7 pro its only about £10 and will drop your temps by about 5c

you should be able to reach 3.7 with a better cooler
