Asus FanXpert tweaking and modding for ultra silent [literally inaudible] computer

Greetings,

I'm fully aware of the fact, that FanXpert is a heavily problematic and hard to deal with program of Asus. I spent three straight days tryin' to tweak this program to "perfection"...and I managed.

First off, it's very important to find a version, that will actually work for You. E.g. for notoriously problematic Asus Maximus VII Impact it's the Asus X99 E-WS [.096] at this moment, and not the one provided, since You can't install update, because it won't run.

Well, anyway, to the tweaking itself.

After running Fan Tuning [I'm using Noctua fans], You will get some better results, as with standard Q-Fan profiles from Asus. But...tuning is not enough, almost never.

That's where LNA and ULNA adapters come to work.

Here is what I did to create inaudible server:

1. Got the working version of FanXpert [this is up to You guys, You can combine versions and change the main driver folder, and do some alchemy here, but I suggest You just try simply diff. versions].

2. Ran FanTuning from Windows with no LNA/ULNA, using Noctua fans [all are pwm].

3. Got the results, I wasn't happy with, no, not really happy with them. They were way too loud to my liking [around 10-12 dba overall from within 30 cm, I am going full extreme].

4. Hit the fans with LNA, ULNA adapters [in my case, the PWM have only LNA, so I used LNA from Noctua].

5. Don't panic here, all the fans will stop for 100%, now here's the tweaking part. Go to Your FanXpet 2.0/3.0 and find the sweet spot, where the fans will start turning. If You go on too low rpm, fans may tick and do some undesirable sounds. Simply go by 1% up and 1% down, and find the sweet spot.

6. My results are exquisite. With open case, 30 cm anywhere from the case [I have passive PSU] I have up to 8 dba noise, which makes it inaudible from away 100+ cm, which is great I believe.

In numbers. My CPU fan is running 120-199 rpm [and they say it's 300 rpm minimal, bah], and all toher fans are 350-400 rpm.

I didn't attach here pictures, if needed, I can do that. I'm back to installing my server now.

I hope that some of You will find this tutorial useful, mainly for those suffering from dip4.dll errors, and other disfunctionalities of this otherwise great tool.

Take care guys!

P.S.: Here's the list of tested fans:

NOCTUA NF-A14 FLX - standard Fan Tuning values: lowest rpm: ~800 rpm, extreme Fan Tuning values: ~350 rpm
NOCTUA NF-A15 PWM - standard Fan Tuning values: lowest rpm: ~560 rpm, extreme Fan Tuning values: ~133-199 rpm
NOCTUA NF-S12A PWM - standard Fan Tuning values: lowest rpm: ~756 rpm, extreme Fan Tuning Values: ~300-400 rpm
