Asus ZenBook UX430UN - Some issues to adress

Fan noise:

I am having some issues with my new Asus ZenBook UX430UN beeing too loud for comfort when under only minor load (browsing with 2 tabs), and found that this was mainly because the fans (at least on my device) have an annoying rattle to it, which is especially noticable at low fan speed (12.5% expecially). Really hard to explain the noise, its like a really quiet car engine, but with that engine rumble like the fans are touching the edges almost. To avoid this annyoing sound I am using Laptop FanControl to allow the computer to run minorly hotter without activating the fans. If anyone knows a good preset for this device let me know, I am using the one for UX310UA wich lets the device get up to 50% before activating fans to 25%. On my old laptop, which was a Lenovo Y700 with dual fans, the fans sounded more like wind and less like a motor. This calm sound might not be possible with ultrabooks, if this sound I am experiencing is normal.

Random and major turboing by the i5 CPU:

Suddenly when a bit of load (say installing a program, beeing on a media-intensive website such as youtube etc) the CPU suddenly boosts to >3Ghz, causing the tmperature to skyrocket to 62 degrees celcius and putting the fans on full. This is REALLY annoying when combined with the loud fan, and I have had no luck creating a startegic reproduction of this incident, it seems to appear very unconsitently.

Theese issues are really annyoing for a machine at this price, so If anyone have some advice or think I should contact the store regarding this, please give me some feedback!

(On the positive, the coil whine is not so bothersome when you concentrate on the fan noise )

Sounds like QC issue, RMA it

This is completely normal, happens in almost every laptop with the same CPU. Since 8th gen mobile chips run hot, I suggest you to undervolt CPU and do a light load profile with lower multi core turbo speeds via Throttlestop (can refer to my laptop reviews to see how to do it)
