Turbo vs. Axial Fan Graphics: The Essential Difference in How They Work
Axial Fan Graphics Card (Normal Game Card):
How it works: The fan draws in cold air from below, blows it to the cooling fins, and then blows the hot air to the left and right sides of the graphics card and discharges it into the chassis. Hot air builds up in the chassis and requires a chassis fan to expel it.
Dependent on chassis air ducts: Extremely dependent on the exhaust capacity of the chassis. That's why we have previously emphasized creating strong negative pressure for multi-card miners to quickly remove this hot air.
Turbofan graphics card (blower type):
How it works: The fan draws cool air from the front of the graphics card (usually the opposite end of the bezel), forces the air through a tight tunnel of cooling fins, and blows all the hot air out of the chassis directly from the IO bezel of the graphics card.
Self-contained system: Each turbo card is an independent cooling system that is responsible for directing its own heat out of the chassis and hardly relies on the chassis air duct.
Why is "both sides ventilating" not the best solution?
What do you think: the chassis fan is also ventilating externally, and the turbine card itself is also ventilating externally, isn't the two-pronged approach the best effect?
In fact, this will cause vicious competition to "grab the wind", which will lead to a decrease in heat dissipation efficiency.
The turbo card needs to "feed": the suction of the turbofan is not strong. It was designed to cool itself by drawing already relatively warm air from inside the chassis. If there is strong negative pressure inside the case, it means that the air inside the case is very thin.
Insufficient air leads to overheating: Turbo cards are greatly reduced in efficiency because they "don't take in enough air." Without enough air flowing through the cooling fins, the heat cannot be taken away, causing the temperature of the graphics card core and memory to rise instead of dropping.
Conflict: The chassis exhaust fan is desperately trying to pump air out of the chassis, while the turbine card needs to draw air in to work. The two are competing for limited air resources, forming internal friction.
Best practice: Build air ducts for all-turbo graphics miners
Instead of expelling hot air (because the turbo cards do it themselves), your goal is to "feed" these turbine cards to provide them with an abundant, cool source of air.
Core principle: Create positive pressure and provide sufficient cold air
You need to allow the inlet air volume to ≥ the exhaust air volume to create a slight positive or balanced air pressure inside the chassis.
This ensures that the inside of the chassis is filled with air, and the turbo cards can easily "drink" the cooling media they need.
Fan configuration scheme:
Strong air intake: Install multiple high-volume fans at the bottom and front of the chassis with dust mesh. These fans can be turned up at high speed, and they are the workhorse of "feeding".
Auxiliary exhaust: Fans on the top and rear of the case are either not installed or run at very low speeds. Their sole role is to provide an outlet for the small amount of waste heat that may be present inside the chassis (from the motherboard power supply, CPU, etc.), rather than the main means of heat dissipation. They must never be allowed to exceed the total exhaust air volume of the air intake.
The exhaust fan can even be removed entirely: for a purely full turbo miner, the exhaust of the turbo card itself is often sufficient. You just need to make sure that there is a strong enough air intake.
Air duct design:
The ideal air ducts are: cold air entering in large quantities from the front/bottom of the case - > being sucked in directly from the front by the turbo graphics card - > hot air being expelled by the turbo card directly from the rear of the case.
This is a very efficient, direct linear air duct that does not interfere with each other.
Summary and comparison
| characteristic | Axial Fan Graphics Card (Normal Card) | Turbofan graphics card (turbo card) |
|---|---|---|
| Heat dissipation method | Exhaust heat into the inside of the case | Exhaust heat out of the chassis by itself |
| Chassis requirements | Strong negative pressure quickly discharges hot air from the chassis | Positive/balanced pressure to provide sufficient cool air to the graphics card |
| Air intake focus | Medium is fine, dust protection | The top priority is that a large amount of high-speed cold air is required |
| Exhaust focus | The most important thing is that a powerful exhaust fan is needed | Secondary, the turbo card is responsible for itself, and the chassis exhaust fan is weak or absent |
| Core contradiction | Solve the problem of hot air buildup | Solve the problem of insufficient cold air |
Final recommendation:
If you confirm that all 8 cards are pure turbo graphics, adjust your strategy immediately:
Weaken or turn off the exhaust fan of the chassis.
Fully enhance the air intake capacity of the chassis and install multiple high-performance fans at the air inlets.
Monitor your graphics card temperature and you should see a significant improvement in temperature after providing plenty of cool air.
