Asrock z77 Extreme4: How do deal with fans running at 100% all the time? - Page 2

post #11 of 19
Not to ressurrect a dead thread, but has anyone resolved this issue?

I have a similar issue with this motherboard.

My CPU fans adjust their speeds just fine.

However, my 3-pin chassis fans run at full speeds 100% of the time. No matter what I set them to in my bios, they still run at full speed.

(note: for those who are not familiar with this board, the extreme4 is supposed to be capable of throttling down fan speeds via the bios - even to 3 pin fans. In fact, the 3 chassis fan ports are only 3 pin, not 4-pin (though there is an additional 4 pin power port, but that is not what we are discussing here)).



EDIT:


Oh and just to clarify, I am using BIOS version 2.00 that came out 7/17/12. This is the latest version at the time of this post.

my MB is in ver 1.4 I have manage to adjust the speed the fans work..all of them using bios settings and then restarting to see the changes take effect. Not all fan controllers setup the same. Some you just set the level 10 is the highest rpm 1 the lower rpm. Other you set a target temperature on wich the fan level kicks in. the only one I have trouble with is Chassis Fan 1 ...it´s allways at full speed no matter the level or temp conditions. Guess I´ll have to buy a fan with lower rpms.mad.gif

just bought this MB recently, it appears that CHA3 header allows control via combining PWM and 12V signals (Aux2 fan speed controller in SpeedFan), but not the other headers. Speedfan only shows 3 controllers to begin with, despite there being 6 headers on the MB and 4 separate controllers in BIOS.
Have yet to exhaust all possible fan controller settings in BIOS (if that has any effect on SpeedFan's capabilities), but it's pretty disappointing so far.
All my fans are 3-pin, I was used to having atleast 2 Speedfan-controllable headers on the motherboard,

UPD: turns out you can control the CPU headers as well (both at once)
SpeedFan | configure | advanced - set PWM mode for all fan controllers to manual
you can then override BIOS fan settings from Windows and set up any speed/T curve you like

guess this board ain't so bad now wink.gif

Can anyone give me a clue on what to think of the level I can set?
I run 3 True Quiets here that can be manually set to run at 1000 or 600 rpms and it seems they run still at 1000 despite setting the fans 1 & 3 to level 7 and 2 to level 3(why does that header use different levels anyway???), I even get some ridicules high readings of the fan speeds jumping from around 1000 to 2000.
At least the CPU fan works, set it to 6 and now it runs around 1780 instead of 2000rpms.

I'm really worried that the fans could get damaged.

Search results had this thread as the second or third hit . I had some fun trying to figure this out myself.

My setup:
- Case is CM Storm Enforcer - Gaming Mid Tower Computer Case with USB 3.0 Ports (SGC-1000-KWN1)
- 2 Fans included by default: 1 x 200mm in the front, 1 x 120mm in rear
- 1 additional 200mm fan purchased for the top: Cooler Master MegaFlow 200mm Red LED Computer Case Fan (R4-LUS-07AR-GP)


Besides the fact everything sounded extremely loud, both of the 200mm fans were running at 1000rpm+, which they were not rated for. I knew I was doing something fundamentally incorrect in my wiring.



Solution for the Storm Enforcer case:
- All three fans are 3pins, therefore, if you plug these into CHA1 or PWRFAN or use the molex connectors (all 4 pin), this will result in the fans running at 100% all of the time if you do so.
- Top Fan: Plug it into CHA_FAN2. Lower to Manual / Level1.
- Front Fan: Plug it into CHA_FAN3. Lower to Manual / Level1.
- Rear Fan: Plug it into the PWRFAN. This is the quietest of the three and even at 100% is not that bad.


Plugging the Front Fan near the CPU seemed counter-intuitive when a closer location was near the bottom of the motherboard. However, this setup did reduce the noise significantly and drop the 200mm fans down to 700rpm, which is what they were rated for.

Hoping this information will help others out. Best of luck.

Hi, guys. I have a similar issue. The difference is that I have all fans (CPU, GPU and case fans as well) running even after I turn the computer off.

I'm using the latest firmware (2.70) on my Z77 Extreme4.

My setup:

- NZXT Phantom 410 case with 3 default fans connected directly to the PSU
- Antec Kuhler 920 Liquid Cooling System (installed on CPU_FAN pins)
- Intel Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA 1155
- GSkill Ripjaws 8 GB DDR3 2133 MHz
- EVGA GeForce GTX670 FTW 2048MB GDDR5 256bit
- OCZ Vertex 4 128 GB SSD
- Seasonic X-850 PSU

I've already switched all components I could... Memory, graphics card and even the PSU.
The problem remains. However the computer works great despite these issues.
Dr. Debug shows no error code when I shut off the computer. It's like the motherboard is really turned off, but with all fans running infinitely.


What do you think, guys?

hey guys i just solved the issue of 100% fans. i have 7 cougar fans installed in my case(supposed to be some of the quietest ones out there), but when they are all full blast there is a terribly loud wooshing sound from all the air moving through the case.
some may be wondering how i have 7 fans plus a water block hooked up on the mobo(no hw fan controller). well here's the answer. i am only occupying the cha1, cha3, cpu1, cpu2, and pwr1 headers. using speedfan i can make my rig whisper quiet
btw i got my ASRock in december 2012, but im not sure what the UEFI version is and i have not flashed an updated rom.

hope this helps those still having problems, i know i'm extremely happy 4 my ASRock(pun definitely intended) and hope the rest of you are having a good expreience.thumb.gif

I chose to set the fans in the bios, and use CPUID HWMonitor to view resulting temp/speed.
At manual/full speed, the case fan was about 2000 rpm, and the cpu fan was about 3000 rpm.
After setting to automatic/50C/level 3, at idle the case fan is 840, and the cpu fan is 2300.
At 90% load (during 20 minute video recode), fans went to full speed as temp crossed 50C, and temps never exceeded 59C.
