Fan Push? Pull?

post #1 of 5
Thread Starter 
So I was looking for some advice on the airflow of my Haf X Case. I have to 230mm pulling air in and a 120mm in the shroud for the gpu's that is also pulling from front of case. Then I have two 200mm on top pushing air out along with my 4 120mm for my H100 Radiator. The 140 mm in the back is venting air out and the 200mm on the side panel is pulling air in. Plus I have a kingston Hyper X fan on my memory. I can take a picture and put arrows in if you like to show a diagram, but I wanna know if there was something I could do to better my airflow? Switch the side panel direction? tell me what you all think?

I was thinking about pulling air from top and exausting for side panel. Make a nice personal Heater for my hands XD

A pic would be nice, but essentially here are your options.

Fan pushing air into case on the side panel towards your video cards will give lower card temperatures. Inverse is true.
Top fans pushing down towards the motherboard will give much lower RAM and VRM temperatures and lower cpu temperatures if you have a tower heatsink and not watercooling. Inverse is true. If you have water cooling, then the cpu temperature won't change.

Those are essentially the 2 main differences that can make drastic changes in temperature in a case build without modding.

If modding or so, having a 140mm or 120mm in the 5.25" drive bay pulling air in would also lower VRM and RAM temperatures and would allow you to keep the top fans as exhaust if you're a man who wants it all.

Front fan should stay intake to keep hdd's in a good temperature range for long life.

I actually run my computer without a side panel so if you're crazy like me and do the same, then reversing the rear fan as intake would further drop motherboard temps without disrupting airflow (because there really isn't any without the side panel on) And because of that, I also have the two top fans pointing at my motherboard and I'll tell ya, it makes a world of a difference for the VRM's because before under load, the vrm heatsinks would get VERY hot and with the 200mm fans pointing down at them, they remain quite cool to the touch. Ram doesn't really get very hot so difference there is minimal.


Ok, with the pictures added. That setup will give you lower gpu temps but slightly higher cpu temps because you're pushing warm air through your radiator. Reversing the top fans will cool the cpu better as well as give airflow to the small vrm heatsink too if you care about that. Though, doing that will disrupt airflow a bit. To get the actual coolest temperatures does require some modding but would be easier if you had a case like the NZXT Phantom that has two stock fan grills near the bottom front. It's not generally discussed but the best temperature yield would be to have every fan near the main components draw in air and all the fans further away push the warm air out. For example, Top fans, rear fans, and fans on the side panel over the video card = intake. Fans in the 5.25" drive bay, fans in the front of the case (and the two 120mm fans on the side panel regarding a layout similar to the Phantom as I mentioned) all pushing air out.
Yes it's weird but it works When components are in direct line with the push vortex of the fan, it'll be cooled much better than being out in the back being cooled by passive pressure.

Yeah I added a picture in so you could see. but just in case the edit is funny...384

what you have right now is good, you could make the top intake and the exhaust only out the back, but thats up to you
