Kingroon K3PS 40mm Fan Mod

thingiverse

Love the Kingroon KP3S, super cheap and all good so far. It's fans are noisy as hell though and mine sits right next to me so I needed to put some silent Noctua fans on there. It's quiet as a mouse now. I also replaced the noisy power supply with a black brick style one, which I highly recommend. You'll need 6 (better to have 12) M3 22-24mm bolts to mount the fans. To mount the fan mount you'll need 2 x M3 10mm bolts and another 2 of those if you want to mount the second part cooling fan on the right. They should be printed in their upright position as in the main photo, I did them at .2 layer height with no support. I used 3 x A4x20 3 pin, 12v Noctua fans. The center one is plugged into a 24v socket and I wired a MP1584EN board (24v->12v) inline. The two part coolers are connected together to the PWM fan port on the mainboard, sharing a MP1584EN. Was going to make a BLTouch mount for it but I couldn't get the damn thing working. *Note in the pic the right hand plastic is melted a bit because I made a wall too thin and welded it shut manually, the enclosed file won't have that problem as I thickened that wall.
