@droftarts Yes U20

@infiniteloop no I don't how hot it is. But blower is connected to 12V and it works all time it blows on all board

@infiniteloop no it is under printer (outside the printer). on cpu I have about 28*C I have blower on board.

@infiniteloop ahh sorry I don't know because in duet website I normal cpu temp bed is on 100* but in chamber I have only 60* I have Voron 2.4

@infiniteloop Poland

@infiniteloop I think so but it is some unreal but the main problem is that
I received duet I was printing it happened U1 "desolder" and sd card not working
I used some hot air and it worked brilliant but yesterday during printing it stopped

@phaedrux I have service of repairing pcb, I needed 3d printer in my company, I added some flux and used hot air it fixed soldering. I used hot air only on chip U1 responsible for sd card. It was minor fix, but during printing with abs where temperature is high it happens again that this chip is being desolder

@jay_s_uk it's problem with chip responsible for sd card (it is called U1 as I remember) I used hot air three times and it worked but now it's going to often to fix in own way
