80x80x38mm High Output DC Fan DC8038G
Seven performance grades across 12V, 24V and 48V versions, reaching 145.40CFM airflow and 86.55mmH2O static pressure at 14,200RPM.
Space for an 80×80mm fan does not always mean the airflow path is easy. DC8038G pairs a 38mm-deep axial construction with multiple operating grades for equipment where heat sinks, inlet filters and narrow internal passages add resistance. Select the part number by the required operating point, power supply and acceptable noise—not by the maximum airflow figure alone.

High Speed DC Fan Specifications and Seven Operating Grades
The DC8038G series contains seven speed and pressure levels for each of three rated voltages. Airflow spans 44.28–145.40CFM; maximum static pressure spans 12.64–86.55mmH₂O. Higher output also brings higher electrical current and acoustic output, so part-number selection should use the complete specification row.

All 21 models use ball bearings. The housing and impeller are glass-fiber-reinforced PBT with a stated UL94 V-0 material rating. Listed function options are FG, RD, PWM, auto restart and polarity protection; confirm the functions and pinout required for the selected order configuration.
High Performance Fan Features for Demanding Cooling Paths
Unlike a standard 80mm ventilation position, a narrow or obstructed air path calls for careful pressure selection. Four characteristics distinguish this G-series design: available static pressure, free-air capacity, seven fixed performance grades and its electrical/monitoring options.
86.55mmH₂O Pressure Capability for Restricted Paths
A high static pressure fan is worth evaluating when filters, closely spaced heat sinks or internal ducts increase resistance. The 14,200RPM DC8038G grade reaches 86.55mmH₂O at the zero-flow endpoint of its pressure curve. Use the full P-Q relationship to confirm a suitable working point at the target airflow.
Up to 145.40CFM in an 80mm Mounting Format
The upper grade delivers 145.40CFM at the free-air endpoint. This gives engineers a higher-output option within an 80×80mm installation footprint, provided the equipment can accommodate a 38mm frame. It is not a promise of 145.40CFM once a grille, filter or heat sink is installed.
Seven Grades for Output, Current and Noise Trade-Offs
Rated speeds progress from 4,500 to 14,200RPM, with published noise values from 41.70 to 71.70dBA. For example, the 9,000RPM model provides 91.24CFM and 51.67mmH₂O at a listed 56.60dBA. These are different factory-rated models, not seven programmable speed settings of every unit.
Ball Bearing Assembly and Optional Signal Interfaces
Ball bearings are specified throughout the G-series model table. FG speed feedback, RD signaling and PWM control can be evaluated where equipment monitoring or command interfaces are required. Confirm the selected functions, control protocol, start-up behavior and wiring before production.
YCCFAN G Series Design for High Output 80mm Airflow
A 38mm-deep 80mm fan series suited to evaluating high-output requirements without changing the mounting footprint.
Choosing between standard DC8038 and DC8038G is chiefly a performance decision, not a mounting-size decision. Both share the 80×80×38mm envelope, but the G series extends to 14,200RPM and 145.40CFM. Verify mounting-hole geometry, power demand and acceptable noise before substituting one for the other.
The PBT housing and impeller, ball-bearing construction and 12V/24V/48V model families provide concrete integration options. At the upper end, electrical loading and noise become particularly important; the specification rows make it possible to assess whether a mid-range grade offers a more appropriate compromise.
Airflow and Static Pressure Curves Across Seven Speed Grades
A high free-air CFM value and a high shut-off pressure value describe different endpoints of the same curve. First estimate the enclosure's pressure drop at the required airflow; then locate where that system-resistance curve crosses a DC8038G performance curve. The intersection, rather than either catalogue endpoint, indicates the expected operating region. Comparing the seven grades can reveal whether a lower-speed option is sufficient or whether resistance calls for a higher-pressure version.
Equipment Cooling Applications with High Airflow Resistance
DC8038G is most relevant where an 80mm installation position is fixed but substantial system resistance must be considered. The following scenarios describe engineering-fit possibilities rather than confirmed customer installations.
Get Cooling Support
High-Density Server Heat-Sink Channels
In a compact server module, air must often pass through closely packed heat-sink fins and board-level restrictions. A server cooling fan therefore needs sufficient operating pressure, not simply a high free-air airflow label. DC8038G offers seven pressure/flow choices; confirm the chassis resistance and noise requirement before specifying a grade.
Industrial Converter Heat-Sink Compartments
Power-conversion assemblies can concentrate heat around semiconductors and finned heat sinks. When airflow passages are narrow, selecting a higher-pressure grade may help address system resistance. The chosen rated voltage and current must also fit the converter's auxiliary supply.
Filtered Control and Electronics Enclosures
Dust filters and protective grilles add pressure loss at enclosure inlets or outlets. DC8038G can be evaluated for filtered airflow routes when the available space supports a 38mm frame; the actual result depends on the filter's loaded condition and the complete path resistance.
Network Equipment with Monitoring Requirements
High-load switching or network hardware may call for both concentrated cooling and fan-status visibility. For these projects, evaluate the suitable pressure grade alongside optional FG or RD feedback. Monitoring signals and connector assignments must be agreed for the exact part number.
Compact Ducted Air-Movement Modules
Short ducts, bends and small outlet sections can increase resistance in integrated cooling assemblies. A 38mm-deep axial fan may be evaluated where both mounting depth and P-Q performance suit the design. The suitability of the selected grade should be checked at the intended installed airflow.
YCCFAN DC8038G Fan Dimensions and Running Demonstration
See the 80×80×38mm frame, mounting points and running direction before specifying a model. A useful demonstration should also show the actual part-number label and, where available, a clearly identified speed grade rather than implying one fan can operate at every listed rated speed.
DC8038G is an 80×80×38mm high-output DC fan family covering 12V, 24V and 48V rated voltages, each with seven speed grades from 4,500 to 14,200RPM. Product videos for this series should present the actual installed depth, mounting-hole geometry and connector orientation so that engineers can confirm mechanical fit before sampling.
When comparing performance on camera, each recording should state the voltage and speed grade being demonstrated, because airflow, current and noise differ across the range. Contact YCCFAN for sample requests or the latest test footage of the DC8038G series.
G Series Fan Pressure, Speed and Integration FAQs
A: Both products use an 80×80×38mm nominal frame, but DC8038G offers higher published performance grades, reaching 14,200RPM and 145.40CFM. The same outer dimensions do not guarantee an interchangeable electrical connection, mounting fit or operating noise.
A: No. 86.55mmH₂O is the maximum static-pressure endpoint for the 14,200RPM grade, while 145.40CFM is its free-air airflow endpoint. Actual airflow and pressure are determined together by the system-resistance and fan P-Q curves.
A: Start with the airflow required at the enclosure's expected pressure drop, then compare the seven published curves. Check noise and current at the selected grade; the 14,200RPM version is not automatically the best option for every installation.
A: No. Choose the rated-voltage family that matches the equipment's power system. Although corresponding speed grades have the same published airflow and pressure values, their current ratings differ; electrical compatibility must be confirmed before substitution.
A: No standard feature set should be assumed for every order. PWM, FG and RD are listed as function options. Specify the required interface and confirm wiring, signal levels and part-number configuration with YCCFAN before production.
A: Supply the available 80×80×38mm installation space, system voltage, expected airflow and pressure drop, target noise, operating environment and control/feedback requirements. An airflow resistance estimate or system curve is especially useful for choosing a performance grade.
