C115i Posted May 13, 2019 Share Posted May 13, 2019 (edited) Hello I have noticed most of you guys put the fan behind the radiator (like in the picture below) I have put it in the front of the radiator (against the front case) should I switch ? Case is 275r Cooler is H115i http://thumbs2.imagebam.com/8b/82/0e/1789f61220959664.jpg Thanks for your advice.

DevBiker Posted May 13, 2019 Share Posted May 13, 2019 It doesn't matter. No need to switch if you don't want to. And plenty of people have theirs configured that way. Link to comment Share on other sites More sharing options...

You could do push / pull :laughing: Link to comment Share on other sites More sharing options...

c-attack Posted May 13, 2019 Share Posted May 13, 2019 Same direction is preferable. It never seems to work out very well the other way. Also, keep your expectations in check for performance gains from doubling up in push-pull. The difference in terms of coolant temperature change will be small. On a 300W GPU, you can eek out another 3C. On a typical 135W TDP CPU, more like 1-2C at most. As for fan placement, the push vs pull thing is fairly overblown. There is not much in terms of performance, but often the more noticeable change is in sound. Some fans sound better or worse in one position or the other. Generally speaking, a fan blade that must interact with two surfaces (radiator and case material) will have a different noise tone than one that only interacts with the radiator. Far too case and fan specific. You just have to try and see which you prefer. Link to comment Share on other sites More sharing options...
