Temperature limitation of each components surface
If you need to calculate more in detail to choose suitable fan in your application, please see the information below.
・ Please use each temperature range of the surface of each component.
・ Please test under your worst/most severe condition. We recommend you to use Type K thermocouple device.
* Please make sure to attach firmly with adhesive when you measure these temp.
・ Please make sure 1) No air flow condition 2) Measure its highest heat spot
3) Operate PSU under all the temperature range and make sure it works stably.
