If you’re not satisfied with the result from thermal tuning, there always fan control to allow you to configure the system fans to behave according to your own preference.

Unboxing & Review: ASUS Sabertooth X99 169

You can configure a selected system fan to either fixed RPM mode or Smart Mode that ramps up according to the temperature.

Unboxing & Review: ASUS Sabertooth X99 170

You can even configure the fans on your graphics card under the VGA tab and first, the samrt mode that ramps up the fan speed according to the temperature curve.

Unboxing & Review: ASUS Sabertooth X99 171

RPM fixed mode is somewhat similar to Manual mode which can be found on the ASUS GPU Tweak to set the fan to run at a fixed speed.

Unboxing & Review: ASUS Sabertooth X99 172

As for Auto mode, the fans will run at it’s default factory settings.

We’ve tried overclocking the CPU with EZ Tuning Wizard and Manual Overclocking, the result is shown in the table above. As the EZ Tuning Wizard takes temperature reading into account, it only manage to push the CPU to 3.978GHz. Using the manual overclocking method, we’re able to achieve 4.5GHz and survive through AIDA64 system stability test for 4 hours.

Memory Overclocking

We’ve managed to overclock our Kingston HyperX Predator DDR4 from its stock 2400 MHz (via XMP) with timing of 16-16-16-39-2T to 3000 MHz with timing 15-15-15-36-2T that is able to survive through various benchmarks without any issue.

USB 3.1 Performance Test

Anvil’s Storage Utilities

By far the most complete SSD Benchmark utility available. The Anvil’s Storage Utilities not only comes with the standard SSD Benchmark function, it also includes other functions such as endurance testing and threaded I/O read, write and mixed tests and option to configure the compressibility of the test data.

ATTO Disk Benchmark

The most frequently used benchmarking utility by many manufacturers for performance specification. As ATTO Disk Benchmark uses compressible data rather than compressible data, it results in higher benchmark scores. We’ve ran the benchmark with transfer size ranged from 0.5KB to 8192KB and total length of the test to be 256MB.

Verdict

Overclocking wise, the Sabertooth X99 doesn’t takes much effort as what we’ve expected due to the absent of Q-code display. CPU and Memory overclocking is fairly easy compared to both Sabertooth Z97 Mark 1 and Mark S, especially for the 3000 MHz memory overclocking result.

As for aesthetics aspect, ASUS’s implemenation of the Thermal Armor on the Sabertooth X99 is definitely the best decision ever as we’ve been seeing the high end TUF boards gone naked since the Sabertooth X58. Not only that it looks good, the thermal armor functioned as a shield for the motherboard to reduce dust intake with additional assistant fan to provide sufficient ventilation to keep the components at a comfortable operating temperature. Another great feature that we really like is the TUF Fortifier (metal backplate) that strengthens the PCB to overcome bending caused by heavy CPU coolers.

In terms of usability, ASUS did a fine job with the Thermal Radar 2 that is made specifically for TUF series motherboards is a good and easy to use thermal management utility that works intelligently with the TUF ICe microchip to achieve optimal heat dissipation of your current system with just a single click. With USB 3.1 support and the presence of both M.2 and SATA Express support, the ASUS Sabertooth X99 is a fully equipped tank that will last you long enough for a couple of years.

Pros

  • 5 year warranty
  • Aesthetically pleasing
  • Very solid and rigid
  • Good overclocking potential
  • User-friendly UEFI BIOS
  • Easy thermal management with Thermal Radar 2
  • Comes with MemOK button to ensure successful boot during overclocking session
  • ASUS AI Suite III has many useful features gathered in a single piece of software
  • Support new SATA Express devices
  • Support for latest USB 3.1 devices

Cons

  • Troubleshooting boot failure takes more effort with the absent of Q-code display
  • Clearance issue for large CPU cooler due to the thermal armor design
  • Extra effort in cleaning as thermal armor have a tendency to building up dust over time
