Question about case fans placement - Page 3

post #21 of 26
Thread Starter 
Okay, then I guess my case is hotter in the top because the fans are blowing there, which in this case is a good thing because the cooler air will be at the bottom where my radiator is ^^.

Exactly.

I have my watercooling setup in such a way that the air temp in my case is +/- 1F comparing any two spots, simply because I have so much air moving. Convection is an extremely slow means of moving the location of warm air compared to even a single fan.

The only way to know what will give you the best actual Temps is to actually labor over the computer trying many different fan configurations. The rest of us are simply giving our best answers based on our experiences.

After some testings I have come to a conslusion that a side fan working as a exhaust does affect the gpu temperature, with approx 2 degrees celsius and 2% in fan speed. I made a new window to my side panel and mounted a fan. Since my cpu is blowing hot air upwards, an extra exhaust fan was needed to remove all that heat in the top of the case. I tried different fan layouts by making a window out of cardboard, so I knew what the deal was once I starteds to cut in the plastic. Soon I have some pictures up.

So an intake in the right side of the window (height: just above the PSU) didn't help reducing temps?

Adding an intake in the case above GPU can only hinder the flow of hot air coming off of GPU. Notice that airflow is from from bottom of case into fans on GPU, out the sides of GPU PCB toward side cover, back, front and toward motherboard where it has nowhere to go except back into GPU fans.
  • Having back of case below GPU open allows airflow from front to back which can help remove the heated air coming out of GpU
  • If window was symmetrical and you could turn is 180 degrees so side fan was intake in lower right of window..


Radiator in bottom is doing one of two things:
  • Sucking cool air out of case that would / could otherwise supply GPU
  • Blowing heated air into case warming up air going to GPU.
  • Could you move radiator to top or back? Would greatly improve airflow if it was not in bottom.

You might find second link in sig helpful.

Well, its all about compromising in this build. As it is now, its the only way to have the fans without making modifications and according to my cardboard template, the most effective solution was to add a extra exhaust fan on the side window to blow all that hot air out of the case. I agree that the radiators suck cold air that would otherwise cool the gpu but I can only have such a thick radiator in the bottom which also greatly improves the space in the case paired with a bay res for the pump. Not ideal build, but good enough for cooling the cpu, which is my first priority.
