Improving Cooling and Air Circulation with an Air Purifier!
Improving Cooling and Air Circulation with an Air Purifier!
Hello everyone,
I'm trying to improve my computer's cooling performance without purchasing new hardware. I've optimized my GTX 780 Ti GPU settings when playing BF4 and want to run multiple programs at once—such as browser tabs, MSI A/B, Speccy, etc.—while gaming. Even when closing all other applications during gameplay, the system can still experience lag. I'm currently using a 20 MHz clock speed and would like to increase it further, but I'm also using medium graphics settings.
Based on my current configuration, how should I adjust my PC's airflow for better cooling? Does this setup provide optimal cooling for the entire system, including the CPU and GPU? If not, what changes should I make?
Thanks in advance!
Hi everyone,
I'm trying to improve my computer's cooling without purchasing extra hardware. I've optimized my GTX 780 Ti GPU for playing BF4, and I want to run my browser and other programs like MSI A/B or Speccy alongside. Even when I close all other applications during gaming, the game can still lag—especially since I'm only at 20 MHz clock speed but prefer higher settings (Medium graphics).
Based on the setup I've described below, how should I adjust my PC's airflow? Does this configuration already provide optimal cooling for the CPU and graphics card, or is there room for improvement? If not, what changes would help?
Thanks in advance!
1. Location:
I positioned my tower case near the ground to work with natural airflow. Heat tends to rise, so cooler temperatures will be felt closer to the surface.
2. Positive Pressure:
- 2 front 120mm intake fans at high speed
- 1 side 120mm intake fan at high speed
- 1 rear 120mm exhaust fan at high speed, specifically for the Corsair H50 liquid cooling unit
- 1 top 240mm exhaust fan at standard 1-speed
This arrangement should create a positive pressure inside the case, helping to minimize dust accumulation and reduce heating from internal components. The rear fan was kept as an exhaust since testing showed better temperature control when cool air met the radiator in a net positive flow.
3. Air Purifier:
I use a non-Ozone emitting, Germ Guardian AC4825 at low speed. I keep it running whenever the PC is on.
The purifier is placed directly above the tower, with the 240mm exhaust fan directing air into it. Clean air then travels about 2-3 feet to the wall, reflects off it, and reaches the front intake fans. In theory, this could help eliminate dust after an hour.
If I were to use the purifier as an intake and direct the exhaust fans inside the PC, would that be more effective? I’m considering placing it right in front of the tower, but there’s a risk of insufficient space for efficient airflow. It might help increase positive pressure, but it could also limit dust removal or air intake.
In short, balancing room-wide cleanliness with targeted cooling inside the case seems key. Let me know your thoughts!

Hi all,
I'm looking to optimize my computer setup's cooling efficiency without buying additional hardware. I OC my GTX 780 Ti GPU when playing BF4, and I like to keep my browser up and running simultaneously, along with some other programs like MSI A/B, Speccy, etc. Even when I close all other programs while gaming, the game sometimes gets laggy (I'm only at 20 MHz for the clocks but I'd like to go even higher, and I'm using in-game Medium graphics quality settings).
Given my current setup described below, how should I go about optimizing my computer's airflow? Or, does this current setup that I have described below maximize my PC's overall cooling, as well as the CPU and graphics card's cooling specifically? If not, how do I improve the setup?
Thanks in advance!

Location:
I placed my tower case low on the ground, so as to work with physics. Heat rises so the relative temperature will be cooler on the ground than if it were higher in altitude.
2.
Positive Pressure:
+ 2 front 120mm intake fans on high
+ 1 side 120mm intake fan on high
+ 1 rear 120mm exhaust fan on high, dedicated to the Corsair H50 liquid cooling for CPU
+ 1 top 240mm exhaust fan on "standard" 1-speed
This should make a positive pressure environment inside the case, thereby reducing dust buildup inside of the case. In effect, dust will not contribute to the heating of the PC's hardware.
The rear fan I left as an exhaust after comparing the CPU temperatures with both exhaust and intake fan setups. The exhaust was a little bit better temperature-wise, and I was told by one computer expert that, given my case's setup, there will be a hot spot created when cool air contacts the Corsair's radiator and becomes heated and trapped in the net positive air flow environment.

Air Purifier:
It purifies air and proactively helps to eliminate dust. I have the non-Ozone emitting, Germ Guardian AC4825 and I leave it on low speed. I try to remember to leave it on whenever the computer is on.
I currently have it so that the air purifier is literally on top of the PC tower. The top 240mm exhaust fan feeds air into the air purifier, whereby fresh air is blown out. This clean air then hits the wall about 2-3 feet or so in front of it, then reflects off the wall to feed clean air to the 2 front intake fans.
In theory, the air purifier should cause the room to become dust-free after about an hour, so assuming that dust is not an issue,
would it be better to use the air purifier to blow much cooler air to the two front intake fans?
I also don't see the benefit of having heated PC exhaust air enter the air purifier - it should be the other way around, where clean, dust-free air directly blows into the air purifier, but space is limited. I could place the air purifier directly in front of the PC tower... but that means that there's about a foot of space between the wall and the air purifier's intake, so I'm not sure that would remove dust or even intake air as efficiently; but it should have the effect of getting cooler air to enter the PC case faster, so it may increase the case's positive pressure. Thus, there's a trade-off: room dust and create clean air for the entire room, vs. dedicating the air purifier to help keep the PC running cool.
Use the purifier as an intake and then use the fans inside the computer as exhaust. The ones in the front make intake as well as the air purifier.
Ok, I'l try that out. I placed the air purifier in front of the PC so that it blows cool, clean air directly into the PC's front intake. That should increase the speed and positive air pressure, as well to decrease the temperature going in.
I'll have to see how that works out. Thanks.
I hope it works!
I hope it functions properly!
It does work!
I tested the air purifier through the front intakes, increased the speed, and noticed a slight improvement of a few degrees according to Speccy. For gaming and overclocking, this might not matter much since I only boosted my settings by around 20 using MSI A/B. If I were playing with friends in a more serious match, I’d probably do more overclocking, but I haven’t tried that yet.
