A Medion Notebook with design-related high temperature development in the HDD area reached after 1-2 hours of operation permanently 48 ° - 55 °. The replacement of the hard disk has been recently required Certainly overheating. The new hard disk should now make merry little longer, because are the notebook cooler, amazingly, even after 6 hours of continuous use only temperatures of 36 ° - 41 ° reached. This is a normal value and an unexpected improvement by 12 ° - 14 ° !!! Another positive aspect is that the fans are almost inaudible. Was measured with the recommended freeware "Crystal Disc Info": I can advise anyone to monitor the hard drive. The mounting feet on the base necessarily fold out and ensure unhindered air circulation. The better and free movement of the air can be sucked in, the better the cooling effect. The orientation of the notebook on the base is for the cooling temperature is not without influence. In our case, we have the highest cooling effect to our 15.3 "notebook from Medion by focusing it on the leading edge of the cooling pad. Because everyone must experiment times and leave via CrystalDiskInfo display the temperature. Caution, for better updating time Crystal DISCInfo Set under "Options" / "Auto Update" to "1 min.".
