Frequently Asked Questions
Do I really need to buy specific fans for my radiator?
You can technically use any fan, but standard case fans often lack the static pressure required to push air through tight radiator fins. Using an airflow-optimized fan on a radiator often leads to higher temperatures because the air simply bounces off the metal instead of passing through it.
How many fans should I put on my radiator?
Most people use a push configuration where the fans are mounted between the case and the radiator. If your radiator is particularly thick, adding a second set of fans on the other side in a push-pull setup can lower temperatures by a few degrees.
Are RGB fans worse for performance than standard fans?
Not necessarily, though the lighting hardware can sometimes limit the space available for the fan motor or blade size. If you want the best performance, look for high-quality models that prioritize aerodynamics even with the extra lights.
What happens if I connect too many fans to one motherboard header?
Every motherboard header has an amperage limit, usually around 1 amp. Connecting too many fans can blow the fuse on your motherboard header, so check the current draw listed on the fan label before plugging them all into one spot.
Should I set my fans to pull air into the case or push it out?
Radiators usually perform best when pulling fresh, cool air from outside the case. If you mount the radiator at the top of your case, you will likely be exhausting hot air out, which is standard practice for keeping the rest of your components cool.
