S Pro Cooling System
The S Pro model uses a passive and active cooling system. The passive cooling system maximizes natural cooling air currents to efficiently and silently cool the laptop.An upward angled laptop support allows rising hot air to exit through back exhaust vents and then to pull cool air through side intake vents. A raised laptop support position with large open air space under and around the laptop allows for natural air currents to extract heat from the laptop’s aluminum case. New laptop support arms and adjustable laptop pads shift the laptop position forward, include 77% larger air channel cutouts for improved cooling airflow along the surface of the laptop’s aluminum enclosure and include adjustable padding for a tailored laptop fit that only covers 0.1% of a 16-inch MacBook Pro’s bottom surface area, which leaves 99.9% of the laptop’s aluminum enclosure exposed for improved heat extraction.

The active cooling system works with the passive cooling system to significantly accelerate laptop cooling while reducing noise. A high-quality, large and powerful 12-volt fan is positioned with open air space above and below, as well as fan screens moved away from fan blades to achieve more efficient operation with maximum airflow and minimum noise. The fan’s significant airflow is directed to the sides and back by the angled laptop, and then again by the laptop support arm’s upward and outward angled design. A large cutout along the top edge of the laptop support arms allows air to move against the laptop enclosure and extract as much heat as possible. The hot air is exhausted to the back and away from the cooling fan’s underside intake vent to avoid hot air recycling.

The active cooling system has a user facing pushbutton switch to select from off for silent passive cooling, low-speed for standard quiet cooling, and high-speed for maximum cooling power. The Cooling Fan is part of the Cooling Stand’s modular system with a bolted connection for easy installation and removal. The Cooling Fan component’s use bolt and snap connections for easily access, servicing, replacement or upgrade. The speed control system uses a standard pin connection that works with 2, 3 and 4-pin fans. Both the speed control unit and fan have been designed to support replacement and upgrade.
 
 
S Cooling System
The S model uses a passive cooling system that maximizes natural cooling air currents to efficiently and silently cool the laptop. An upward angled laptop support allows rising hot air to exit through back exhaust vents and then to pull cool air through side intake vents. A raised laptop support position with large open air space under and around the laptop allows for natural air currents to extract heat from the laptop’s aluminum case. New laptop support arms and adjustable laptop pads shift the laptop position forward, include 77% larger air channel cutouts for improved cooling airflow along the surface of the laptop’s aluminum enclosure and include adjustable padding for a tailored laptop fit that only covers 0.1% of a 16-inch MacBook Pro’s bottom surface area, which leaves 99.9% of the laptop’s aluminum enclosure exposed for improved heat extraction.

The S model can be upgraded to the S Pro model with a Cooling Fan upgrade that adds active cooling.
 
 
S Mini Cooling System
The S Mini model uses a passive and active cooling system. The passive cooling system allows air to flow around the bottom and sides of the Mac Mini.

The active cooling system works with the passive cooling system to accelerate cooling airflow around the bottom and sides of the Mac Mini. For users that choose to remove the Mac Mini’s bottom cover, then the cooling fan drives cooling air directly into the Mac Mini for immediate and dramatic cooling of internal components, including the processor.

The active cooling system has a user facing pushbutton switch to select from off for silent passive cooling, low-speed for standard quiet cooling, and high-speed for maximum cooling power. The Cooling Fan is part of the Cooling Stand’s modular system with a bolted connection for easy installation and removal. The Cooling Fan component’s use bolt and snap connections for easily access, servicing, replacement or upgrade. The speed control system uses a standard pin connection that works with 2, 3 and 4-pin fans. Both the speed control unit and fan have been designed to support replacement and upgrade.

 
S Pro and S Mini Cooling Fan Specs
- The Cooling Fan provides active cooling with the Cooling Stand Pro (S Pro) and Cooling Stand Mini (S Mini), and can be purchased separately to install on the Cooling Stand (S).
- The Cooling Fan uses a high-quality Noctua 120 x 120 x 25mm 12-volt case fan with 9 blades, and a long life ball bearing rated for 150,000 hours (over 17 years of continuous operation).
- The Cooling Fan's low-speed cooling mode runs at approximately 1200 RPM and produces approximately 50 CFM airflow, 1.39 H2O static pressure and 19 dB(A) noise level.
- The Cooling Fan's high-speed cooling mode runs at approximately 1700 RPM and produces approximately 71 CFM airflow, 2.83 H2O static pressure and 25 dB(A) noise level.
- The S Pro includes an optional user installed Air Deflector accessory. Users can choose to install the air deflector to provide an increase in directed cooling performance and to prevent air from hitting their hands.
- The S Mini includes an optional user installed dust filter accessory. Users can choose to install the dust filter to help reduce dust accumulation for users that choose to remove the Mac Mini’s bottom cover for direct internal component cooling. Use of a dust filter slightly decreases airflow and increases noise.
- Note that the Cooling Fan's RPM, CFM, Pa, dBA, and bearing life specifications are approximate and may vary.
S Pro and S Mini Cooling Fan Service, Replacement and Upgrade Specs
- The Cooling Fan has been designed to be serviceable, replaceable and/or upgradeable with a bolted and snap fitted modular assembly.
- If the fan and/or speed-control PCBA unit require servicing or replacement, then the Cooling Fan can be detached from the stand and sent to SVALT for servicing or replacement. In some cases it may also be possible for SVALT to send a replacement fan and/or speed-control unit to the customer for their installation. In support of our customers, servicing and/or replacement is covered under a limited one year warranty, and when outside of the warranty, then servicing and/or replacement fees are minimized in support of our customers.
- If SVALT upgrades the fan and/or speed-control PCBA unit in the future, then the Cooling Fan can be detached from the stand and sent to SVALT for upgrade. In some cases it may also be possible for SVALT to send a fan and/or speed-control PCBA unit upgrade to the customer for their installation. Future upgrades fees are minimized in support of our customers.
- Note that if user opens the Cooling Fan to perform servicing, replacement and/or upgrade, then they could cause damage that may not be covered under warranty. Please contact SVALT prior to opening and/or working on the Cooling Fan.
S Pro and S Mini Cooling Fan Replacement Specs
- The Cooling Fan has been designed to fit and work with standard off-the-shelf fans rated 12 volt and sized 120 x 120 x 25 mm (a fan gasket on the top and bottom of the fan can help accommodate fans with slightly larger or smaller +/- 1 mm variations in 25 mm thickness).
- The speed-control PCBA unit uses a standard mini 2-pin fan snap-connector that can accommodate 2, 3, or 4-pin fans.
- The speed-control PCBA unit has been designed to DC24V and 1A maximum. While the system is designed for a 12 volt fan with maximum 1A, the low-speed setting may not support a 1A fan, and the provided power supply only supports up to 0.4A (400mAmp).
- The speed-control PCBA unit's low-speed setting uses a 68 Ohms 3 Watt resistor. The user must calculate the power dissipated for their selected fan's maximum Amp rating, which should not exceed 2 Watts. Note that each fan model has a minimum recommended operating voltage, so the user must also confirm that the low-speed setting will operate above the fan manufacturer's minimum voltage.
- Note that SVALT products may only be used with the certified and marked LPS (Limited Power Supply) power supply that shipped with the product.
Back to top of cooling tab
S Pro and S Mini Cooling Fan Operation
- The Cooling Fan provides active cooling with the SVALT Cooling Stand Pro (S Pro) and SVALT Cooling Stand Mini (S Mini), and can be purchased separately to install on the SVALT Cooling Stand (S).
- The Cooling Fan system includes a user facing pushbutton switch to select from three levels of cooling and audio performance (off, low and hi). Pressing the switch cycles from off -> low -> off -> high -> off and then repeats. The lower LED lights up when set to low-speed and the upper LED lights up when set to high-speed.
- OFF - Select off for silent passive cooling. When the Cooling Fan is turned off or not installed, the computer can be used with the benefits of silent passive cooling.
- LOW - Select low-speed for quiet active cooling. When the Cooling Fan is set to low-speed, the large fan uses less restricted airflow to more effectively cool with whisper quiet operation for general use and audio sensitive conditions. Low-speed runs at approximately 1100 RPM and produces approximately 45 CFM airflow, 13 Pa static pressure and 16 dB(A) noise level, and is considered to be silent in offices with typical 45-60 dB(A) noise levels.
- HIGH - Select high-speed for maximum active cooling. When the Cooling Fan is set to high-speed, the large and powerful fan drives significant quantities of cooling airflow for high-intensity applications and workflows. High-speed runs at approximately 1700 RPM and produces approximately 71 CFM airflow, 28 Pa static pressure and 25 dB(A) noise level, and is considered to be audible but quiet in offices with typical 45-60 dB(A) noise levels.
- Note that the Cooling Fan's RPM, CFM, Pa, dBA, and bearing life specifications are approximate and may vary.

S Pro and S Compatibility
The S Pro and S models are designed for universal passive and active cooling compatibility. The design has been optimized for current generation Mac laptops, like the 16/14-inch MacBook Pro M1 Pro Apple Silicon laptops, as well as all prior Mac laptops and all PC laptops that we are aware of (typical laptop designs place hot air exhaust vents along the side and back edges of the laptop).

The S Pro and S models were designed for universal support and fit with all Mac laptops as well as all PC laptops that are at least 9.5 inches side-to-side edges and 10.25 inches front-to-back edges. We are not aware of any laptop made that is too large or too heavy for the Cooling Stand’s significant support capacity as the Cooling Stand uses a bolted heavy metal support structure that is oversized so that even the largest and heaviest PC gaming laptops achieve a stable support. The support base is made from 1/4 inch thick 6061 aluminum and the support arms are made from 11 gauge cold rolled steel. Each arm has two #10-32 fasteners bolting it rigidly in place to the support base. The laptop support arms use a deep beam design to maximize strength and rigidity, while offering unimpeded cooling airflow. The support arms include adjustable pads for a tailored laptop fit with improved cooling airflow.

Compatibility is based on SVALT’s supplemental cooling system working with and boosting a laptop’s builtin cooling capabilities. To better understand how Apple laptop’s builtin cooling systems work and how SVALT products improve laptop performance, please see our article on Laptops

 
S Mini Compatibility
The S Mini model is designed to work with all current and previous Mac Mini computers. For Mac Minis that have a removable bottom cover, the support pads have been design to work with the cover on or off. When the cover is off, the padding locks the Mac Mini in place so that cooling air is driven directly onto the internal components for immediate system wide cooling.
- 2005 - 2009 Mac Mini 1st and 2nd generation include a taller silver aluminum and white plastic enclosure that uses cool air intake vents along the front and side bottom edges.
- 2010 - 2017 Mac Mini 3rd generation includes a thinner silver aluminum enclosure that uses a cool air intake vent along the front edge of a removable round bottom cover that once removed exposes components for increased cooling performance.
- 2018 - 2019 Mac Mini 4th generation includes the thinner space gray aluminum enclosure that uses cool air intake vents around the edge of a removable round bottom cover that once removed exposes a perforated metal screen covering for increased cooling performance. An iFixit pry bar is included to assist users who choose to remove the bottom panel.
- 2020 - 2021 Mac Mini 5th generation includes Apple Silicon and that uses cool air intake vents around the edge of a removable round bottom cover that once removed exposes a perforated metal screen covering for increased cooling performance. An iFixit pry bar is included to assist users who choose to remove the bottom panel.
Note that operating the Mac Mini with the bottom cover removed may not be considered normal operating conditions for the Mac Mini by Apple, and could impact warranty. A user installed dust filter accessory is included to help reduce internal dust accumulation, however, the user needs to first install the filter, and then to clean accumulated dust from the filter and computer as required. Dust filters reduce airflow and increase noise levels for a given airflow.

The Cooling Stand’s solid front panel blocks cooling fan airflow and noise, as well as hiding cord clutter and user accessories. When placing items behind the front panel, consider the following:
- When placing items that generate heat, then some portion of that heat will transfer to the computer through line-of-site proximity heat radiation, rising hot air currents, and/or fan driven air movement. To lessen heat transfer to the laptop, or when maximum laptop cooling is desired, then avoid placing items that generate heat close to the computer.
- When placing items under Cooling Fan (S Pro or S Mini models), then note that the maximum available open space under the fan is 2.125 inches in height. Placing large and/or tall items directly under the fan will reduce fan efficiency, lower airflow and/or increased noise. To lessen these effects, do not place tall user accessories directly under the fan intake, and for maximum cooling efficiency, do not place anything under or around the fan.

Introduction to Testing
Computer processors generate heat which can increase temperatures, and when running intensive applications that heat can cause throttling and limit performance. Supplemental cooling can only increase performance under throttling conditions, however, the computer uses throttling to reduce temperatures and reduce heat damage. That means supplemental cooling that effectively improves cooling will allow the computer to run with reduced throttling and increased performance, but that also means that temperatures could be higher because of the higher processor power. In short, less throttling means faster and hotter. So if throttling occurs, then it is challenging to simultaneously test temperatures. Conversely, if throttling is not occurring, then it is impossible to test performance. For this reason, each test is conducted to analyze either temperatures or performance, and not both.

To test supplemental cooling and to accurately measure its influence on temperatures and performance, SVALT tests under strictly controlled variables so that SVALT supplemental cooling is the only variable influencing the results. Each test session includes two tests, one with the SVALT supplemental cooling device and another without as the control. Conditions are as close to identical as possible for both tests (ambient air temperature, physical placement, non-thermally conductive insulated base, starting laptop temperatures, internal fan speeds, eliminated non-test background activities, and single applied testing workload) and results are based on direct sensor data logs (component temperatures, processor power and speed, etc).

S Pro Testing Details - All Tests
- Computer: 2019 16-inch MacBook Pro (top-spec 2.4GHz CPU and 8GB GPU) with the screen open, a fully charged battery, running on an Apple power adapter, and setup per Testing Guide.
- Process: Two tests were conducted under controlled conditions per Testing Guide, a SVALT test with a Cooling Stand model S Pro set to high-speed, and another CONTROL test without the S Pro. Both tests were conducted on a flat non-thermally conductive insulated base and surrounded by open space without influence by an external cooling or heating source.
- Ambient: Testing was conducted in a single room without windows closed and covered, and mechanical system dedicated to conditioning only that single space. The mechanical system was used to maintain a constant 75F temperature throughout testing. Temperatures were monitored by multiple gauges placed around the laptop and outside of any direct heating or cooling source.
- Data: Overall setup photos were taken throughout the testing process to document testing conditions. Terminal automated screenshoots were captured every five minutes. Raw data from the laptop sensors was logged to CVS files through TG Pro and Intel Power Gadget applications. These data logs were used to calculate cooling performance by averaging data into 15-min segments, which were then used to generate the graphs and to calculate percentage improvements relative to the computer’s baseline settings.
