Se previous M5A99X question

Ok. I still can't get my mobo to see my fan (4pin 120MM arctic f12. My chassis fan runs, but the bios and fan xprt aren't picking it up. Am I doing something wrong or is it a problem with my chassis fan or am I just purely out of luck with ASUS MOBO monitoring my Chassis fan.

If it is a fan problem, anybody have a recommendation?

The last time I used an Arctic 4-pin PWM fan it used the PST system and had a plug and socket at the end of the fan lead. The plug and socket were linked with a short length of cable. Deploying the Arctic fan as a chassis fan meant unplugging the CPU PWM fan, connecting the Arctic fan to the CPU PWM header and then plugging the CPU fan into the socket on the Arctic fan lead. This shared the PWM signal between the two fans, but only the RPM of the CPU fan was reported. This is normal for PWM sharing.

I would add that my Arctic PWM fan also had a separate yellow lead with a plug on the end of it. This lead was the fan speed sensing cable. If your fan has this you can plug it into one of the chassis fan headers. The 3 pin PWR_FAN header is easiest because it should be next to the CPU fan header. The speed of the Arctic fan should then show up in the BIOS and any fan monitoring software as Power Fan Speed. This was Arctic's way of providing both PWM fan sharing and allowing the fan speed to be monitored. You may have to turn on Chassis Q-Fan Control in the BIOS for this to work.

It looks like the new Asus Z97 motherboards may now have multiple real PWM fan headers. Not sure if I believe it, and looking forward to the boards being released so this can be confirmed.

Upgraded Fan Controls
ASUS Z97 motherboards feature full Pulse Wave Modulation (PWM) on all fan headers (4 pin). This allows users far better granular control over fan speeds on top of the capability of having far quieter operations. The 4 pin fan headers can automatically detect PWM or DC type fans.

Yes, the end of the 'fake' 4 pin headers. According to Asus the Z97 motherboards also feature Fan Xpert 3 which "...puts 4-pin/3-pin CPU and case fan controls in one place. It scans each fan's characteristics and delivers custom settings for each fan based on the dedicated area temperatures detected by hardware thermal sensors. Make sure every fan achieves the best balance of cooling performance and low noise. Fan Xpert 3 supports hardware-level PWM/DC combo mode for both the CPU and case fans. It even can reduce the CPU fan speed to below the default minimum, for extra-quiet and power saving operation during light loads...".

Interesting info, personally i don't fully believe it, as in the past they have stated similar things.... but maybe they learn their lesson and adjusted so all are like the cpu fan that can be switched in bios.

The Asus web site is just starting to list manuals for their Z97 range, and have looked at them... the chassis fan headers still seem to be of the 'fake' variety since the connectors are labelled in exactly the same way as the Z87 boards (Z97 PRO and ROG Maximus VII). It is possible that this is a mistake, and the connector diagram from the Z87 has simply been copied over. However in terms of published information the 'fake' 4 pin fan headers issue seems not to be going away :shock:

Edit: Having just checked the manual for the Asus Z97 Deluxe, this has all of its chassis fan connectors labelled as PWM. The manual also says "...the chassis fan connectors support DC and PWM modes. To set these fans to DC or PWM, go to Advanced Mode->Monitor->Chassis Fan 1/4 Control items in BIOS..". So a full fan control Z97 motherboard is available from Asus but only apparently at the premium price of the Deluxe.

Asus seems to have really fixed the fan control issues for the Z97 series - for mainstream, Rog, and Tuf, which is good news for quiet computing.

Here is JJ at Asus explaining the improvements (fan control in EZ mode at 5 min, but at 8:40 gets into the advanced fan control): http://www.youtube.com/watch?v=Y79pSiaR2dg

It sounds good, that there will be full choice of PWM, DC, disable, on every fan header, the choice of temperature input for each header, fan calibration of every fan to find min and max for the exact fan, and even the ability to have a fan stop or start at a temperature value, and all in the bios. Controlling the fan ramping characteristic is only in ai suite though.

As you may have noticed the board featured is the Z97 Deluxe which has, and is documented as having, the full set of new fan control features. It still isn't entirely clear whether these features are going to be applied to every Z97 motherboard in the range. If they are, that sounds like really good news. But the online Z97A manual for example currently makes no mention of dual PWM/voltage control or temperature sensor selection choices. Maybe it's just a cut and paste issue, but either way Asus need to adjust their online documentation to clarify exactly what the fan control situation is with each of their Z97 motherboards.

Somewhere around 41:30 JJ goes into Fan Xpert III: down to 20% speed, silent mode to disable chassis fans and minimal CPU cooler rpm.

In the overview video, it's a Pro card, but he also states that every board starting with the A and the m-ITX boards will have this functionality.

Would be great to have someone test the new Z97/H97 Asus mobos, specially interested into if its as smart as it sound with the CHA_FAN able to be switched to PWM... i doubt it, but would be a good addition to have much more flexibility not only on planning the build, but on upgrading down the road.

I might be doing a build for a friend in the next few months, and considering the Asus H97 Plus, and probably will go with it even if the fan control is like the Z87/H87/B85/H81, as the motherboard has a good CPU position for the Node 304 and it has 3 fan headers (CPU_FAN, CHA_FAN1 and 2), so ill be able to control the PWM fan with the CPU_FAN, the back Fractal 140 with the CHA_FAN2 and the two frontals Fractal 92mm with the splitter of on CHA_FAN1. If i do build it ill test both on the bios and with FanXpert3 to see if CHA_FAN can manage PWM and 3pin fans automatically, i hope im wrong, but i don't think they will be.

What doesnt look that hot is the bios still, asus finally uploaded the manuals for their new motherboards, and from the Asus H97 PLUS manual, the CHA_FANs are now resticted to 60% as their minimum.

Image

I still believe that FanXpert3 will enter and override the bios fan restrictions, and fans will go as low as they can, as its been my experience with past gens.

The major difference between the Z87 and the Z97 boards is the inbuilt Q-Fan tuning via the Q-Fan Control section of the BIOS. It is here that the voltage or PWM option can be selected for fans, and a Profile or manual setting selected. The Q-Fan tuning section of the BIOS does not replace the Monitor section. That it still there and has the previous options for CPU and chassis fans. So for the Z97-Pro for example this means that the minimum 60% duty cycle manual BIOS setting for chassis fans still applies. The issue then seems to be that for some of their boards Asus are saying that the 60% can be over-ridden by Q-Fan tuning. The Asus Z97 Pro manual for example in the part of the manual covering the chassis fan manual settings adds that "...the values may differ via Q-Fan tuning...". So it seems that you can still have 'fake' headers but only if the traditional BIOS settings are used in preference to Q-Fan tuning.

Edit: Having looked at the Asus H97-Plus manual there is a section (2.2.3) on the Q-Fan Control which implies that this board will have the same voltage/PWM options and Profile/manual tuning options as the Z97 range. So is the absence of the wording about Q-Fan tuning just a documentation issue?

Hey guys!

Has anyone figured this out yet? Do we now have true PWM headers on H97-PRO?

I just bought an H87-PRO and after being very frustrated with my fan setup and reading this thread I am considering "upgrading" to the H97. I really don't feel like rebuilding my rig from scratch again just to see that ASUS have cheated again. Has anyone tested it yet?

...after researching my options a little more, I am not also considering Z97. Does anyone already have experience with them?

Here's what I am looking to do:

I currently have an H87-PRO with an i7-4771 in a Coolermaster 690II Advance case with 3 Noctua fans attached: NF-A15 PWM front intake, NF-F12 rear exhaust and a NF-F12 attached to a Coolermaster 212 EVO. I won't be doing any OCing (impossible on the 4771 anyway) and what I am looking for a as silent a system as possible. Ideally the intake and exhaust fans should work at their minimum speed of 300 RPM most of the time for good airflow and positive pressure to keep dust out and only spin-up when the CPU has been working under full load for a while and is getting really hot.

Currently I don't see a way of doing this with the H87-PRO. I have the front and rear fans attached with the LNA adapters and Fan Xpert can spin them up only starting at 50%, e.g. around 650 RPM, which is not very loud, but it's certainly not silent either. Since I am not planning on upgrading and I don't really need any of the other features of the Z97-PRO or the H97-PRO, what I really care about are the true PWM headers.

Would I be able to control the fans with real PWM and keep them at 300 RPM with the H97-PRO or the Z97-PRO?

Thanks in advance!

I don't think anyone but an owner can respond you that, and atm i haven't seen one yet.

The intake and exhaust fans could be run as a PWM chain from the CPU fan header using the PWM Y adapters, and if need be PWM extension cables, supplied by Noctua. This would allow all three fans to run at the PWM duty cycle setting of the CPU fan. Intake and exhaust fan speeds would be less, most likely somewhere in the 350 to 450 rpm region. Using this setup requires the CPU fan to be plugged into the four pin socket on the first PWM Y cable to give an RPM reading.

Hi!

I have a Asus Z87I-Pro and would like to use SpeedFan but without luck - BUT version 4.50 fixed earlier bugs so that rpm, temps are show correctly.

Do tell if you find a way to control the fan using another program than fan xpert 2, as it is only controlled by the CPU. I need to control by GPU.

Did you set up SpeedFan properly, I mean, according to SPCR guide?
