Supposedly, this improves dissipation and prevents heat from building up. Air is sucked in from inside the chassis and then expelled.

Older PC cases manufactured according to the ATX specification put the power supply just under the case's top. Otherwise, you're fighting the forces of convection, and possibly creating a situation where a screw or other loose part could fall into the power supply. You should go this route only with passively-cooled 'silent' PSUs, so that the warm air can rise.

Here are pictures of the case and the cpu cooler for you guys to have an idea of what I'm talking about.Don’t install the PSU with its opening facing up in the chassis. Wouldn't it be better to flip cpu fan to actually push air outside of the heatsink, giving a much more streamlined airflow and in theory better cooling? The cpu fan is placed horizontally, so the cpu heatsink airflow is vertical, and the fan actually blows air on to the heatsink, that being the opposite of the case airflow and being so close to the PSU intake fan I think it could actually affect the performance of the cpu fan and the one on the PSU. Not only does this help cooling the rest of the components but it helps with the airflow within the case because it removes the air from the intake fan in the front panel.Īll of this looks great on paper and by now you are probably thinking why do I even bother in starting this thread. So I looked it up and found a couple of reviews that actually put the PSU intake facing downwards with good results. Furthermore the hardrive actually goes over the PSU, and this one not being a modular one, I really can't think of another place to putting the unused cables over it as well, thus completely blocking airflow on the top of the case. Now cooler master recommends to put the intake of the PSU facing upwards so it takes air directly outside of the case, but this approach doesn't help with the airflow and cooling of the rest of the components. I opted for the latter with the noctua NH-L9i cooler which is only 37 mm tall with the fan included. That really cripples down the options for cpu cooling to basically water cooling (which is not an option for this system as it goes way over my budget) and a low profile air cooling solution. It is has cubic form factor and the PSU goes directly over the motherboard, leaving only 70 mm or about 3' for a cooling solution.

This case is very compact and has very little room for cable management and airflow. The relevant components for this questions are the Cooler master elite 110 case, the corsair VS 550 PSU and the Noctua NH-9Li cooler. So I have the parts of my living room media/gaming build coming in a few days, and I was wondering which direction (pushing or pulling) is better for this system. I have a question to which I wasn't able to find a real answer browsing through the interwebs, so I appeal to your knowledge.
