H100 Fan go crazy on Boot!

I just changed my H80 for a H100 Cooler and at every boot the fans speed up like crazy and after a few seconds the slow down, It was the same with the H80 so im wondering is it suppose to be like that ?

 

Getting a little worried that they will wear out as they sound like a frikking jet plan on boot :eek:

Yes, that is normal, it takes a moment for the H100's fan control firmware to start up. This can happen with mother boards and their fan speed control too, I have several boards where fans connected to them run at full speed during POST, and then slow down when the boards fan control software starts up. Another example of this is after a BIOS/UEFI flash on a board, the BIOS settings are at default settings and the fan control settings are disabled, so the fans run at full speed.
