A new research project by Australian researchers has found that only a fan with a maximum speed of up to 30A is recommended for most screens.
Key points:The study found the maximum fan speed for most 1080p screens is only 30AThe researchers found fans with a lower speed of 10A and 15A were not recommendedThe report says fans with speeds above 20A should be considered for a few 1080p monitorsThe researchers’ study was conducted using three 1080p 1080p devices that were purchased from Australian retailers.
The study analysed the fan speed of four 1080p displays, using four different fan speed settings.
“The majority of 1080p display screens are designed for the high-end desktop, where they are typically used for multimedia,” Dr Matthew Hockett from the University of Technology, Sydney, told ABC News.
“In these cases, the minimum speed of the fan is generally 20A.”
But in general, the higher the fan, the less airflow is required.
“The researchers tested three 1080P devices: the Acer Predator Z3, the Asus P9 and the Asus VivoBook G5.
All three had a standard, 80mm fan rated at up to 10A, with an 80mm-sized, 120mm-wide fan rated to 15A.
The Predator Z5 had an 80-inch (1,300mm) fan rated for up to 20A, while the Predator Z6 and Z7 were rated for 15A and 20A respectively.
The Vivobook G5 and VivoPhone 5 had smaller 120mm fan speeds, with the Vivo Phone 5 rated at 20A and the VivaPhone 5 rated for 20A on the V7.
The researchers measured the fan speeds of the four devices using their internal accelerometers to measure the force exerted by the fan on the screen.
The results were then compared to their maximum fan speeds for each device.
The higher the number of fans used, the more airflow was required.
The top-speed fans were found to be the most efficient at providing maximum airflow and reducing noise.
The scientists used their accelerometers as a measuring device to measure airflow, and also the amount of heat generated as a result of the cooling fans, to see if the higher speeds of high-speed fan made a difference.
They found that when fans with the highest speeds of 20A were used, there was no difference in the amount heat generated when compared to fans with lower speeds.”
We did find that the fan with the lowest fan speed had a significantly greater cooling effect,” Dr Hocketts said.”
So we found that the fans with higher speed are actually less efficient at this than the fans that have lower speeds.
“He said the difference in efficiency was small, but it could mean that fans with slower speeds might be used if they provide the required cooling for a larger screen.”
Dr Hockets said the findings were consistent across the different screens.””
But if you are using them for larger screens, you are actually reducing the amount the screen cools.”
Dr Hockets said the findings were consistent across the different screens.
“It’s important to note that we did not find any difference between fan speeds with lower fan speeds and higher speed,” he explained.
“These results show that fans of varying speed are not the only way to cool a screen, and there are many ways to cool it.”
The study was published in the journal Energy & Society.
