In addition, large diameter fans rotate slower for a given airflow than small fans and hence, again, operate more quietly. Also, by eliminating sharp edges near the fan blade, the audible noise level is reduced further.<\/p>\n<p>As the variable speed fans on the QM7 are controlled depending on the inlet temperature, the optimum amount of cooling is always available with the minimal amount of audible noise.<\/p>\n<p>For more information about the QM series, please visit the product page: <a href=\"https:\/\/www.emea.lambda.tdk.com\/uk\/qm7\" target=\"_blank\" rel=\"noopener\">www.emea.lambda.tdk.com\/uk\/qm7<\/a><\/p>\n<p>Click here to find out more about <a href=\"https:\/\/www.emea.lambda.tdk.com\/uk\/products\/acdc-power-supplies\/\" target=\"_blank\" rel=\"noopener\">TDK-Lambda\u2019s AC-DC power supply ranges<\/a>.<\/p>\n<p>If you have a <a href=\"https:\/\/www.emea.lambda.tdk.com\/uk\/faq\/ask.aspx\" target=\"_blank\" rel=\"noopener\">question you\u2019d like to ask TDK-Lambda<\/a>, please feel free to use the online FAQ form and we\u2019ll get back to you with an answer to your question as soon as possible.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A number of design features help make the QM7 operate quietly, improving the user and patient experience of the medical system.
