apropos fan noise, there is separate thread when actually i proven, that it’s not an issue, but side efect of how Intel Turbo works on this CPU.
long story short: there is nothing to be done, as cpu at 4GHz gets hot , very fast, so fan need to speedup in order to cool it down.
Intel Turbo can overclock single core, or group of cores. but more cores you will load, less frequency you will get.
that can be counterintuitive but you can generate more temperature with single thread, than 6 thread.
