Re: My blog of building a quiet mini-itx computer

Good news in the fact I managed to have the graphics card problem sorted out. Asus support said to install everything again from a clean disk. I did uninstall the drivers and deleted the directories used, but that didn't work. In theory, taking a graphics card out and plugging it back in again shoul...

My woes of building a quiet mini-itx computer The pwm-dc controllers arrived. The cpu and the dual board top/fan fan controllers work fine. The only limitation thing is that if you lower the starting rpm, then you also lose a few rpm at the top end. In between the Asus Bios and Speedfan, I'll sort s...

Re: My blog of building a quiet mini-itx computer

More conclusions. Start with as quiet as components as you can! The hard disk is behind the front fan in front of a grill - direct sound path. So the hard disk affects the front fan noise greatly. With top and cpu Scythe AP-15 fan @ 750rpm and front Scythe AP-14 fan @ 600rpm and 1 hard disk in place...

Re: My blog of building a quiet mini-itx computer

A discovery from all my testing. The front fan cools the hard disk and graphics card but is not critical to the cpu temperature. The cpu fan and the top fan are critical to the cpu temperature with the cpu fan being more important. Because of the way my build is set up, the Noctua NH-C14 pulls half ...

Re: My blog of building a quiet mini-itx computer

Not good news :(

I applied the oil to the Scythe 13 & Scythe 15 bearings and they became noticeably noisier.

At full rpm at 0cm, they have become 4-5 dba noisier after lubricating them.
