Hello to all,I'm investigating about fan noise of my ds4014 and discovered inside chips are very hot!, expecially 4 ic without heatsink which reach 80c, after some check I ordered from rs 9 heatsink 4x 17x17 and 5x 10x10 self adhesive, and result was good now if you see second ir pic with only one heatsink fitted see difference... ,about fan I replaced with noctua make running at about 1000rpm, fitted reverse pushing air inside and 10-15° inclined to center, this decrease a lot the noise and cooling seem to be good, now temp is max 27 from system stat, before was 34-36 max at about 17c room
