M.2 Thermal Guard - GIGABYTE Ultra-Efficient M.2 Thermal Guard

With durability in mind, GIGABYTE provides a thermal solution for M.2 SSD devices. The M.2 Thermal Guard prevents throttling and bottlenecks from high speed M.2 SSDs as it helps to dissipate heat before it becomes an issue.

Smart Fan 6

Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. Multiple fan headers can support PWM/DC fan and pump, and users can easily define each fan curve based on different temperature sensors across the board via intuitive user interface.

Headers & Sensors
- 4 PWM/DC Fan Headers
- 6 Internal Temperature Sensors

High Current Support
Each fan headers support PWM and DC fan and Water cooling Pump , and up to 24W (12V x 2A) with Over-Current Protection

Precision Control
Up to 6 temperature/fan speed control points for precise fan curve

Dual Curve Mode
Slope/Stair dual mode for different user scenario

Fan Stop
Fan can stop completely below users' specified temperature point

Smart Fan 6 BIOS UI

1 - Improve fan curve UI - We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.
2 - Slope/Stair dual graph mode - Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval.
3 - Manual Input - For advanced users, we provide fan speed manual input for more precise control.
4 - EZ Tuning - Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.
5 - Fan curve profile - Fan curve profile can be saved in BIOS ROM, profile will be kept after updating BIOS.

FAN STOP

Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature-all of it can be customized to your liking.
