Ok, so the solution was to boost the LP filter to 130khz in SDRAngel. I dont know why, but this made the Lime transmit on full power. I had timesync installed already and i know it is mandatory
Now it works. Keep in mind that my HF antenna is just a ham stick on my Balcony and it is far from optimal.
I have installed 30x30x10 Suono 12V FAN to the PA, it works like a charm and is quiet enough.
Here is my config that actually works. This is LimeSDR Mini and 3-4W Leory 2-700MHZ Alliexpress $9 PA
