Thanks. The 256KiB and 1280x1280 restrictions took a bit of effort to satisfy, but it's much better now.

I think chose very good components and thus you ended with a very good quiet pc, congrats.

Hope you share hows your experience with Asus bios fan control, while mine is not that great, i do think asus is good into making things better each iteration. Im interested on seeing how the Qtuning is working, does it correctly test each fan establishing the correct values, can you make your personal breakpoint graphs, and they a breakpoints be placed below what the qtuning established?

Haha.. at first I didn't even realize how to calibrate the fans. It's called 'Optimize All' on the Q-tuning page.

The two GP-12s got their minimum values reduced to 27% and 24%, maybe due to variance in the fans. That's down from the original minimum of 60% :D I was really unimpressed with them at first! I still find them to sound a bit like drones at 900+ RPM, and it seems like there's a slight rattling sound coming from them, but at lower RPMs they might not be terrible. Most importantly, after calibration now they don't start at 900 RPM when they turn on. That was unbearable.

I still prefer the Noctuas. Their minimum after calibration is 14%, down from 20%.

There are 3 breakpoints that can be set on the graph in manual mode. I'm not sure if the fan % follow the curves (lines) created or if it's treated as a step function based on the points. But the graph does seem to work. The points cannot be set below the minimum from calibration (or defaults before calibration!).

I'm still learning and setting things up. It's been a long time since I made a desktop system, so much of what's in the BIOS is unfamiliar. Let me know if you want me to try anything.

Btw, right after I placed my order for the motherboard, I noticed a note on the ROG forum that the latest BIOS has a known issue with fan calibration :S At least it worked for me... for now.

Well you describe more or less how it was my experience also, so now you are running the Fractals around 400rpms?

Yea Noctuas have very good PWM design, most will drop very low, around 15% PWM and in some cases they can be stopped, with FanXpert after running the tuning (on the software not the bios) you can set silent profile and it will allow you to drop the fans like Noctua below their minimum PWM and thus stop them. But since you are on linux you are practically binded to bios fan control. For me the Noctuas are fine under low rpms, but when loaded and reaching above 800rpms i find the tone not that pleasing, i prefer bequiet pwm, specially the BL067 is right now my gotto fan for 140mm, bl066 for 120mm, although on 120 there are lots of options to chose from.

Thanks for the info, its the same with me, the problem that i did enconter is that i cant place them below what the tuning establish so on pure bios i couldnt stop the fans, not that i wanted to but both MSI and AsRock do allow this. I did encounter other issues while playing with the breakpoints, sometimes i change one and it change all others and in some cases like it glitch and reboots the pc, and its still is like that (i updated the bios like a month ago on H170 Pro gaming). I still dont get why asus dont allow the users to place whatever they want, why restrict the user.

Either way, i think you will be fine, as you were able to drop the fans to inaudible levels so you should have a very quiet pc under linux.

Yes, the lowest I saw while monitoring in BIOS was right around 400 RPM.

I haven't observed a range of behavior yet, but yes around 1k RPM it seems fans get annoying. The bequiets are still on my mind because the GP-12s have a rattling/vibration/tinny sound which dominates especially at low RPMs. I find it quite annoying.

I should have mentioned before, there is a checkbox to turn the fan off below the minimum breakpoint. It is not available for the CPU fans, but the GP-12s chassis fans can and do turn off completely and start up gently (i.e. not at 900 RPM). I didn't try using the Noctua as a chassis fan (it's on CPU OPT), so I'm not sure if it's exclusive to DC or also for PWM mode.

I've read elsewhere that these BQ fans have (or at least had) a problem with their PWM controllers, that tend to give an exponential curve, rather than linear results. Any idea if this problem has been sorted? Otherwise, they seem to be ideal silent case fans.

Do fans typically have a linear response? My guess would be that the exponential response is intentional, since I think that makes the most sense for silence: flat at idle and low load, then rising sharply to 100% under load. This also avoids minor up/down ramping of RPMs which will be more distracting than a low-level sound.

It does mean that a user would probably want to use a simple linear fan curve since the "fan curve" is already built in to the fan itself. Or if the user doesn't want it to be exponential, they'd need to make a logarithmic fan curve to linearize the fan response. Might be tricky, but I would think that adjusting the fan's behavior should be do-able.

I would suggest that a linear response is preferable. You can plug in any PWM percentage you like for any temperature threshold, so the response curve really in no way constrains the shape of your temperature-to-rpm curve. However having most of the RPM change clumped in the top quarter or so of the PWM (as happens with exponential response) means you lose fine granularity of control in the region, and a single PWM percentage point can mean a large RPM change:

... this PWM control issue wherein there is a massive drop in fan RPM going from 100% PWM duty cycle to even 99% PWM duty cycle ...

For someone who just wants to stick a fan and have it "work" silently out of the box, the pre-made exponential curve might be preferred. Again, this is purely a guess. But yes, a linear response would probably be preferable for a tweaker.

I have not experience what he describes, weather was BQ design problem or a user/setup issues idk, in my experience the PWM fans from BQ BL066/67 behave linear, weather its fixed or my setup is inmune to what he encounter is something that i cant confirm, but what i can tell you is that i didnt experience his problem more than 18x BQ PWM fans (12x BL067 and 6x BL066).

Sadly im not home, not ill be for the next two weeks, so i cant post the BL067 (140mm), only one that i still have online was the BL066 (120mm), in my testing you can see it has a linear behavior,

One thing worth noting is that if you see his graphs is the 90-95% where the graph climbs fast, the rest of the graph is somewhat linear, so either way what will affect is, you might not be able to fine tune between those ranges, but those are load ranges for me, and i try to keep setups below 1000rpms, so in essence even if it was a issues (that i haven't encounter) i wouldn't be affected sort of speak because i don't go into those ranges, again in my personal testing i have not seen a behavior like what he encountered.

Now if you guys fear the BQ fan, then look into Thermalright TY147ASQ, its the same fan as the TY147A just on a square frame, one just reach home before i left and i tested it and seems very good fan overall, with the same performance of the TY147A, the only downside for some SPCR users is that the fan dont stop, even at 0% pwm it will spin around 300rpms, but thats inaudible to me, very good candidate, specially for someone wanting to maintain the Fractals black and white themes.

Is there any ticking/bearing noise expected from the BL066 or BL067? Eg. https://youtu.be/GAhFDG7HHk4

I got one of each and I hear this (irritating) sound. It's more obvious on the BL066 especially since it's an exhaust fan and thus more exposed. In a very quiet room I can sometimes still perceive the sound at ~1m. The BL067 has a similar but quieter and lower pitched version of the same sound, although since it is an intake fan in the Define C, I can't hear it except within a few cm of it.

----------

The two Fractal Design GP-12 that came with my case have an even more pronounced ticking sound. It is lower pitched, but with more separated "tick"ing sounds. Fractal Design sent replacements (still GP-12), and they are quieter but the sound is still there.

The sound of air is not bad at all with the GP-12 especially at low RPM where it can be inaudible, and even at the full 1k RPM, I find it acceptable for full load situations. But that ticking drives me crazy.

The NF-A14 is perfect at low RPM. No ticking, inaudible at 1m or even less, and within a few cm it's just a very low hum. Perfect. But at higher RPMs, especially past 1k and definitely at 1.5k RPM, there is rather distinct sound. @Abula Now I understand what you mean by the Noctua "tone". I previously wrongly accused the GP-12 for that sound, which I described as a "droning" sound.

----------

Other notes about the system:

- Asus Crosshair VII Hero WIFI is either great or terrible. For some it works perfectly out of the box. For me, it was freezing in UEFI and crashing while editing fan curves in UEFI. The firmware seems beta quality at best, and maybe there was a defect in my board. I RMAed it. The second one I got hasn't frozen in UEFI so far, but I still got crashes when editing fan curves.

Btw, there are 8 fan headers (not counting a fan extension header for adding even more..). All 8 are configurable with fan curves, but the AIO_PUMP and W_PUMP+ headers lack a few options like a time delay for fan speed and minimum RPM settings. Also, CPU_OPT is a mirror of CPU_FAN, so it is not independently configurable.

Cons: buggy firmware, sensors (temps, fans, etc) don't all show up in linux requiring recent kernel modules (it87) to gets some of them, known issue with fan calibration in firmware causing jump to 100% fan speed though workaround seems to be to make less steep curves

Pros: most configurable/full-featured X470 board (OC, RAM tuning options, etc), two M.2 slots with PCIE X4 for both (raidable), ability to flash firmware without CPU or RAM

- G.Skill F4-3200C14D-32GTZ seems like among the best choices for 16GB RAM modules. It works at 3200MT/s on the C7H with DOCP settings. Not having RGB reduces cost a bit and also avoids problems in some cases where SPD info gets corrupted by RGB software.

- Ryzen 7 2700X: works great especially for multicore tasks. Out of the box and with air cooling, it reaches 4.3GHz on single core under light loads. Under stress tests (mprime) it might reach 4.15-4.20GHz single core, 3.95-4.0GHz all cores. This is with default settings on the C7H.

Asus also has a Performance Enhancer settings (level 3 and level 4) which can improve on AMD's Performance Boost2 / XFR2 / Performance Boost Overdrive configurations. With PE level 3, it can sustain under stress tests 4.35GHz on single core, 4.1-4.15GHz on all cores. The downside is the temperatures/voltages can spike higher when going on/off loads.

In general, the 2700X has very spiky temperature behavior. At idle, it could be 5-10C above ambient with the NH-D15, but background tasks can cause continual 10-20C fluctuations from idling temps. eg. if idling at 40C, it could jump to 50C or 60C with minimal activity, especially if PE3 is enabled.

This makes setting quiet fan curves more challenging, but I have managed to have it inaudible at idle and light load situations by having fans ramp up only after 55C (case fans) or 65C (cpu fans). A time delay on fans also helps reduce reactions to spikes.

If the NF-14 fans are prevented from reaching 1.5k RPM, I find the noise level to be quite acceptable for full load situations. I might try the LNA later to achieve this. The worst is when they jump from ~800 RPM to 1.5k RPM, which happens in some stress tests.

- Noctua NH-D15... glad I got this. The ease of mounting has been great as I had to remove/reinstall a few times for RMA etc. The cooling performance seems good, and I'm happy with the sound characteristics at idle and low load. Also, the RAM clearance is great with only the middle fan mounted. I installed the front fan on the case instead, as there isn't enough clearance above the G.Skill TridentZ in the Define C. I might later install a 120mm fan which would fit, if it helps with temps/noise.

- MSI fanless GT1030: no noise, runs displays fine. I'm happy.

- Define C: Good. I've kept the top moduvent open, with just the mesh dust filter. It doesn't seem to make much difference in noise level, but having it closed gives the fans a more echoing "tunnel" sound when they are maxed. I hope having the top open also keeps temps a bit lower at idle.

- Corsair RM650x: As far as I can tell, the fan has never turned on even during stress testing. Happy.

Glad most of the things are working out for you, and nice feedback on your build.

I cant hear any ticking on 6x BL066 but i usually run them around 500-650. If you want to try other 120s, read Fan Roundup #6: Scythe, Noiseblocker, Antec, Nexus, Thermalright, its old but has some of the best fans in the market, from that review
Nidec Servo GentleTyphoon 120mm 1450 RPM - it undervolts well you should be able to drop it below 400rpms, the only downside its it uses real ball bearings some people get bother by this sound (im immune to it =P )
Nexus Real Silent120mm - This is my recommendation for value, Nexus has been a very good fan for SPCR members, now there are more options, but back then this was the holy grail, still today to me its a very good fan for what it costs.

Other options, that to me are good, specially if you want PWM fans,
Noctua NF-A12x25 PWM - Getting great reviews, to me its a very quiet and has a very big range of operation. I like the tone.
Noctua NF-S12A PWM chromax - Very quiet in my experience, but works best without much restrictions, behind filters it struggles but as your exhaust it should be fine. And finally in black =).

I was not a fan of them, but i never heard much ticking, maybe my hearing is getting bad or im inmune =P.

I own a ton of A14, and i dont like their tone, i like more BQ BL067 but since you have issues with the ticking, in case you want something else, check Thermalright TY-147ASQ and Noctua NF-P14S Redux 1200 PWM.

Sad that you seem to have the same issues i still have with my Asus H170 Pro Gaming, it has been reported a long time in asus ROG forums of the bios issues with setting up fan curves. This is the main reason i no longer use Asus on motherboards, and why i suggested you to go with AsRock X370 Taichi (or now X470).

Intel also spikes a lot from 30C to 50C with very light load, when planning fan curves i usually test before where are the spiking reaching, then i try to go with steady fan % that can take this spikes and not let it pass for example 50C, then i ramp the graph up, this helps me a ton not having the computer with a breathing effect and still have inaudible setup on idle and still very quiet on load. Some people even go the extra mile and have some fans stop and turn them on under certain conditions like having 1 fan off until 50C is reached, etc, but this is all planning from each individual.

Thanks for the feedback, one of the most recommended PSU on SPCR forums, cheap and run very quiet, i have built on the 750 and 850 and all were very quiet psu even under load.

@Abula, as usual, thanks for the suggestions. The NF-A12x25 seems perfect for the front of the NH-D15 with taller RAM. I'll keep that in mind. I wasn't planning on more purchases just now! haha

Could you let me know if you can make out the noise of the SW3 vs SW2 in the youtube clip above, and whether your BL066/7 fans make a similar sound? I hear something very similar in my BL066/7. Be Quiet! support said there is a sound they don't recognize in that recording, but to confirm they would need to have it in their labs. They suggested I RMA.

Here's a short recording of the ticking sound of the GP-12. https://instaud.io/2idn Sorry it's not the best quality (webcam mic..) but maybe it gives an idea of what I mean.

----------

Yes, the C7H wasn't my first choice, but the ASRock X470 Taichi was delayed for so long. And the PCIe lane distribution of the C7H is unique and potentially more useful to me.

Taichi Pros: doesn't have Asus firmware issues, has sensors that are detected in linux out of the box.
Cons: 1x1 WiFi, no BIOS recovery option! That last one scares me considering how much I've had to use it with the C7H

Overall I do really like the Taichi though.

----------

I should mention I did have to RMA the Corsair RM650x at first. There was a "loose" capacitor on the PSU blocking one of the ATX connectors from plugging in. Maybe it was fine and just needed to be nudged aside, but it isn't the kind of surprise I want on a new PSU. Also, I haven't gotten the mail-in rebate yet, but that's another story...

----------

One lesson is that it's important to buy from a retailer with a good RMA/return policy. I've had to RMA almost half of what I bought :/ Corsair, Asus, Fractal Design, maybe Be Quiet!... I might be picky, but is it too much to ask for decent quality control? At least Newegg has free RMA/shipping for defective items.

Another lesson is that it's important to check for defects, obviously before the return period expires, but also before removing the UPC for mail-in rebates. Over here, the Asrock motherboards, for instance, have a nasty clause on their MIR that requires mailing in the UPC within 10 days of the invoice date! Once the UPC is cut, retailers won't accept returns even for RMA, which means it's a hassle for consumers, and perhaps a nasty tactic by manufacturers to lock in sales. Luckily, I did not cut the UPC for my PSU before discovering the issue, but if I had to RMA to Corsair I would have had to pay shipping... on a heavy PSU... totally negating any savings. All that just to get what was paid for in the first place.

I run my BL067 at 50% until 50C, the usually idle around 530rpms with this settings, close to what the video showed (although im not too sure he has the same model, he posted HIGH SPEED, i doubt mine is that as mine only reached 1000rpms), i have the BL067 on top, i just placed my hear next to the grill of the Air 740, and i cant hear anything like the ringing i hear in that video. I have read there are some mobos that do have issues with the PWM implementation of bequiet, i think was gigabyte, i can say that they work fine on MSI and AsRock, not sure on asus, but i would have heard it when i tested them on FanXpert3 back when i first got them.

Thanks for checking. I run both around 500 RPM too. With the BL067 it's really hard to hear, but I went looking for it since it's so obvious with the BL066.

You made a good point about PWM implementation, so I tried in DC mode as well on the BL066. It's slightly less pronounced but the sound is still there. I varied the PWM signal from 11% to 100%. At 100% it is the least obvious, but I'm not sure if it's intrinsically less or just relative to the sound of air. At 40-50% which is typical normal usage, it's quite noticeable. At 11%, it tends to stall or almost stall and is rather rough. I wonder if the problem is with the fan or the motherboard's PWM implementation, I would have thought that would be standardized.

Also, the BL066 feels rough in my hand when it's running; it vibrates more forcefully than any other fan I've handled so far. It feels and sounds like an engine that's running rough. I'm tired of RMAing, but this is too noticeable to me.

Btw, I think the HIGH SPEED in the video is the BL071 (PWM) and the other SW3 might be the BL065 (DC).
