"The Asus Zenbook S 13 is the slimmest OLED ultrabook worldwide struggles with annoying fans. The new Zenbook S 13 leaves us with mixed feelings, particularly since last year's model was so good. Asus has completely reworked the device, making the laptop noticeably slimmer. The result also looks good and the case makes a great impression, particularly also in terms of the stability. The new plasma ceramic surface feels great, and there are no problems with fingerprints. In addition, it now includes some of the known connections such as an HDMI port and a regular USB-A connection, which is a good achievement in such a slim device."

"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
