Hello guys my pc has only one exhaust fan 80mm,i just replace it with a new silent one that it less rpm.My previous fan was working at ~2200 rpm and it was noisy thats why i got a new one.The problem here is that since i have changed the old fan with the new one my cpu fan from max 1800rpm is working at 2200rpm and my new exhaust fan is working at ~1500rpm when it says MAX 1200rpm.I changed the fan to make my pc more silent but it is making the same noise.My temps are fine cpu goes max ~57c and graphics card almost same as cpu(my cpu is fx 4300 and gpu is gtx 1050)
