Is this config better then by the book one ?

Hi

For the sake of science ( Just kidding ) i've made top 2 exhausts coz physics says hot air rises lol.

mounted CPU cooler horizontally rare fan, front fans (2x120mm) are intakes.

there is a one 120mm fan on side panel which was not there by default so with help of a drill a marker and scale i've modified side panel for GPU intake.

Now i don't see more then 5C increase/decrease in temps under full load and idle. (CPU cooler was vertical before there was only one rare exhaust all other were intakes and side planes was just a shiny plastic panel)

All fans are at 1500 RPM (24/7) coz they are dead quite.

i'm just confused am i sacrificing top front intake and its doing nothing but pulling cooler air for top front exhaust so its bearing won't get too hot or this config is still better? or should i go back to my old config?

Please advise.

Thanks

Hot air rising isn't factor in PC cooling. Not inside the case. Inside the case fans dictate how air moves. Only when there are places where fans airflow doesn't reach, you can have laws of physics in place (with cool air being heavier and hot lighter).

 

In that config front bottom fan doesn't contribute to general airflow at all. Its just cooling HDDs, there's not enough space between drives to allow air to move freely. GPU looks like blower-style cooler. So any air its getting from front will exit to rear. Dissipation of GPU PCB is close to nothing. Even with full backplate there's no difference in CPU temps (I've tested this in my own rig). In fact, having rear and top exhausts and cooler like in that pic gives few degree better temps than having it in normal orientation. The front of your top fans is doing close to nothing. You might get better temps by having rear also as exhaust instead. But don't change top to intake, that would hurt more than help.
