Mx Specs: Testing

TESTING

SVALT model approximate performance comparison, graphic rendering.

The Mx product line was designed to exceed all prior models with extreme cooling capabilities. The Mx's massive thermally conductive heatsink silently pulls heat from the laptop to help reduce laptop temperatures and quiet laptop built-in fans. The Mx’s optional fan cooling system helps tackle extra high-intensity and long-duration workloads.

Test Results

SVALT product cooling and audio performance shown in the graph above is approximate and based on a wide range of averaged and normalized testing. SVALT conducts a variety of tests through conceptual research, product development and final production proving phases. Test results are meant to provide a more general understanding of built-in laptop cooling systems and how they respond to supplemental cooling. Actual results vary depending on a SVALT product’s configuration, fan, fan speed setting, laptop model, laptop configuration, laptop operation, workstation setup, external monitor setup, and overall testing conditions.

Mx tests conducted with the laptop in closed-screen operation while connected to a single low-resolution external monitor. Comparison tests conducted with the screen open and without an external monitor for high and low stand models.

• As a general condition for all laptop models, adding a high-resolution external monitors and/or multiple external monitors will increase demand on the laptop and generate more heat. Demand and heat generation can be reduced by using only the laptop’s built-in display, or by closing the built-in display and connected to a single low resolution external monitor.
  
  
• As a general condition for 2021+ MacBook Pro, the laptop runs cooler when in closed-screen operation and connected to a single low-resolution external monitor as compared to using a single high-resolution monitor, multiple monitors, or running in open-screen operation. As a result of the 2021+ MacBook Pro's back edge hinge venting design, these laptops are among a small group of laptops that do not see a large reduction in temperatures when the screen is open, or conversely, are particularly capable when running in clamshell mode.
  
  

Mx tests conducted with multiple Mx model configurations.

• As a general note, results were more similar than dissimilar between the different Mx model configurations. When selecting a Mx model, it is recommended to select a model based on a desired workstation setup, such as the dock supports to position the laptop upright with screen closed and moved aside to free up desk space, the high stand supports to use the built-in display and have it raised higher for improved viewing ergonomics, or the low stand supports to have a low-profile setup with the screen closed or with the screen open to type directly on the laptop keyboard.
  
  
• Silent heatsink cooling is approximately consistent across the three side supports types and two material types.
  
  
• Fan active airflow cooling with the heatsink is approximately consistent across the 140mm bolt-on fan and 80mm Fx separate fan configurations.
  
  
• The following slight differences in cooling between side support and fan cooling system configurations were observed:
  
  
• For all laptops and devices, the low and high stand supports have a near horizontal laptop support orientation, which allows the weight of the laptop to press down onto the heatsink’s conductive coupling plate, which in turn increases conductive heat transfer between the laptop and heatsink.
  
  
• For all laptops and devices, the 140mm fan's larger size allows the fan to generate slightly more airflow for a given amount of noise generation. The 140mm fan's larger size also allows the fan to span the full width of the heatsink and nearly span the full length, which moves more cooling air over/through the heatsink cooling fins and removes more heat from the heatsink.
  
  
• For most laptops and devices, the aluminum supports have a thinner 0.300 inch thickness compared to 0.500 inch wood support thickness. The thinner aluminum supports have a slight improvement in cooling airflow compared to the thicker wood supports.
  
  
• For the 2021+ MacBook Pro and other laptops that include a center intake vent along the back/hinge edge, the aluminum low stand supports with FxB22 Cooling Fan provides slightly more cooling because the low stand supports have increased heatsink conductive coupling, because the aluminum supports have less thickness, and because the low stand positions the laptop’s center intake vent so that the Fx Cooling Fan can simultaneously cool the heatsink and drive air into the laptop for direct internal processor cooling.
  
  
• For the 2022+ MacBook Air and other laptops that do not include a center intake vent along the back/hinge edge, the aluminum high stand supports with 140mm bolt-on fan provides slightly more cooling because the high stand supports have increased heatsink conductive coupling, because the aluminum supports have less thickness, and because the high stand raises up the heatsink so that an enormous 140mm fan can quietly and efficiently cool the heatsink.
