Some queries on cooling (beginner)
Some queries on cooling (beginner)
Hello everyone, today I assembled my first rig with assistance from a nearby PC store. Here’s the setup:

I have four fans in total—one rear, one CPU fan, and two front ones. The person building my computer had all the exhaust air coming out, while none of the fans were drawing in any air. The CPU fan is pointing toward the rear exhaust. Is this a positive or negative setup? I’ve read many articles but haven’t found a clear answer.
Supports your idea with scuzzycard and Scotttray. The first two fans should be intake units paired with one exhaust unit <- is that your PSU fan? (and the CPU fan facing inward toward an exhaust – it depends on the cooler; if air reaches the outside, refer back to the simple paper airflow tests, checking if the airflow moves the paper and how much.) Having more intakes than exhausts can cause negative pressure, which helps prevent dust from building up inside the case – definitely better than a setup with too few fans.
Hopefully you can easily swap them (turn the front fans upside down).
Any further questions? Feel free to ask.
It would make more sense for the front fans to be intakes. There's all that negative pressure and not even a strategically-placed vent that could take advantage of it. Nope, not good.
Agree with scuzzycard. The two front fans should handle intake while the rear fan manages exhaust. This setup ensures good airflow and positive pressure to keep dust out of the case. Keep an eye on system temperatures; if they rise, you can add more fans as needed.

I agree with scuzzycard & Scotttray. The first two fans should be intakes paired with one exhaust. This setup matches your PSU fan configuration. (And the CPU fan facing inward toward an exhaust—depends on the cooler and whether sufficient air exits the PC. Use the simple paper test again to check if airflow affects the paper movement.) More intakes than exhausts can cause negative pressure, which helps prevent dust from settling inside the case. This setup should avoid positive pressure issues.
Hopefully you can easily swap them (turn the front fans upside down).
Any further questions are welcome—feel free to ask.
(sorry about that)
Thank you for choosing me as the top option even though I had it wrong.
By the way, regarding dust, get a can of compressed air for affordable cleaning—avoid vacuum cleaners and regular paper towels, which leave fibers behind. Use compressed air to blow out the dust and then use a vacuum (but don’t touch any parts). Compressed Air is the best approach here.
