hello everyone, this is my first post here, I really need some help with this issue and I hope someone with similar issue could provide some insight about this.
so after I took my pc apart for cleaning and re-applying the thermal paste on the processor, when I put everything back I noticed that the motherboard chipset fan (pch fan) was spinning at full speed, so I figured that because I disconnected the motherboard from the psu the bios resetted, so I went into the bios and made sure that the q-fan is enabled and the pch fan control is set to profile and to the lowest setting ( silent), after restarting the pch fan didn`t respond to the to the bios command and still spinning at full speed, which is very laud, i have tried all sort of solutions such as trying different version of bios, other fan profiles, disconnecting the pch fan header and connected it back, but nothing helped, whats really bothering me is the noise, this thing is really Lauder than all my fans in the case and is distracting, what I have also notice is the chassis fan-1 doesn`t report its connected into the bios or fanxpert, it just spins with no fan speed or anything, but apparently when I connect another fan it reports the speed which is weird.
p.s posted this issue in rampage iv extreme owners club but unfortunately got no responds.

I would appreciate if anyone facing similar issue even with different motherboard from different venders as this will help me determine what is causing the problem.

thank you all in advanced waiting for your replies.

Are you absolutely sure that fan spins at 100%? I have another system where RAM has tiny fans. Those fans get either dirty overtime or ball-bearing oil dries out and they become loud, even though they are not at 100% speed. In such case I open a tiny cap where ball-bearing is and put a drop of WD-40 (I have to do this like once a year or so).

If it's not the case for you, the only other thing I'd do is reset the CMOS and then change only the PCH fan without touching anything thing else to see if it affects the fan.

thank you for the quick reply, yes I am sure its spinning at 100%, I have only had this motherboard for 4 months or so, I tried resetting CMOS but this didn`t help, I don`t knows whats causing the problem, when I installed my motherboard back, first the cpu fans would spin a bit then stopped, and the pch fan was spinning at 100%, fixed the cpu fan issue by tweaking the bios and flashing it to the latest version, but the pch remain at 100% despite all the tries.
am guessing bios conversion has something to do with it, since the problem only appeared after converting the bios ( was of after conversion )after a week or so when I uninstalled the motherboard.
another thing I would like to add that might help in determining what could be causing the problem is when I removed the motherboard one of the standoffs was hocked to the screw and it took some kind of force to remove the motherboard from the case and removing the screw from the standoff, I don`t know if this is relevant by anyway, but perhaps I damaged something while doing that, everything runs fine on the motherboard, I only got few blue screens after installation but this was fixed.

perhaps someone with similar issue could shed some light, cuz if I have damaged something I don`t think the motherboard would even boot.

well I have been thinking of getting the sabertooth x79 lately so if this issue is not solved I might as well sell the baby and get the sabertooth or the asrock x79 extreme 11 ( overkill) instead, despite me loving the ROG theme and ROG features on the MB,

I am currently on vacation and on my g53sx but am posting since I have time and this will make solving the issue easier when I get back.

I hope I can solve this issue.

Could not happen that the fan is spinning at 100% because the South Bridge overheats? Maybe when you forced to mobo to take out, the SB block came loose...

Clear cmos and load bios optimized default settings. Sometimes fan speeds get crazy if this is not done.

I checked the temps on the pch when the fan was running at 100% in the bios and I think it was close to 49c - 55c, so there isn`t any overheating issues, I even disconnected the pch fan and used the pc for a while and everything was fine, the heatsink is attached properly and everything seemed to be in place as I made sure of everything when I noticed the problem.
I did clear the cmos and loaded optimized defaults but all that didn`t help I also tried different version of bios but the issue persisted

so, if the problem still can't solved,maybe you can plan the moterboard to repair and test....

Confirm that all the little wires are plugged correctly into the socket.
A fan at full speed, and not being monitored indicates a potential issue with the little connector that hooks the fan up to the motherboard.
If the motherboard isnt sensing a speed, it cant control the fan speed.

Also, try setting the profile to duty at 50 percent and see if that changes anything.

I did indeed made sure of that and I also connected and disconnected the pch fan header, the pch fan reports speed but I cannot be controlled through the bios, the one that is not reporting the speed is the chasiss fan-1 but am suspecting its an issue with the fan itself since when I connect another fan in the header, the new fan reports normally.

have anyone heard of this type of the problem before, cuz I cannot find anyone that is facing the same issue, seems like am the only one with such problem.

another suggestion, is there is a way to convert the bios back to the old format, before version 1404 ? perhaps if I convert the bios back the problem might disappear.

For 1404 you can flash to an earlier bios http://event.asus.com/2012/mb/USB_BIOS_Flashback_GUIDE/ renaming the bios file R4E.ROM

If you have run the CAP converter you can flashback to a 1.xxx BIOS (from 2003 onwards) by renaming the BIOS file ERALL.ROM...

thank you for the quick reply,

I will certainly do that as soon as I get back home, maybe it will fix the problem, thanks for the info it was very informative.

Im having the same problem with PCH fan running at full speed, can't control it in the BIOS?

I was successfuly able to flash the bios back to the previous format, but unfortunately it didn`t fix the problem, pch fan speed still running at full speed no matter what, this is getting confusing, I wonder if its hardware or software related.

Something similar happened to me. What I think fixed the issue was leaving all fan control settings enabled even if they are of no use. For example, I had cpu fan disabled cause I watercool my cpu and this prevented other fans to respond to their individual settings. Hope this helps.

no luck, this is really weird, I cant even see if there is any physical damage or temper to the fan wiring or anything near it.

It's run at full speed since I've had it which is about 4 months. I tried to adjust it a few days ago and It does'nt respond to anything I do, just runs full speed around 5800 RPM?

you should send it to asus, for replacement if it bothers you much, I would if I could but I don`t live in USA and I broke my pcie clip so the warrenty is voided, currently I have disconnected it and my pch temps are 44-45c, am keeping it disconnected until I figure out how to fix it or until I get another motherboard, I don`t think I am able to live with the noise this little thing produce, its so high pitched, I have like 7 fans currently running in my case and its very quite but when I connect it, the noise dramatically increases.

Sent board away for RMA, got replacement. Works fine now. :D

good for you, glad you got it fixed :), mine is still the same, but it doesn`t effect anything, and it won`t really mater if I watercool in the next few months, I even wonder what was the main reason behind adding a fan in the first place since it doesn`t effect the temps much, the funny thing is I almost sell it for like 300$ but then I had cold feet, I guess I got attached to it and I don`t want to sell it anymore, more like you ( you never know what you got until its gone ) feeling, I didn`t really saw spending more money to get asrock extreme 11 or even downgrading to the sabertooth x79, one guy recommended me to invest in watercooling since its worth it and it will completelly eliminate this fan issue from the equation. so this idea actually stock in my head :)

Yeah, if you get a waterblock for the board bye bye fan. You can simply unplug the white plasic bit from the board and it will stop of course!! And the pch will not overheat if you have even minimum airflow in your case...Or get a resitor and rig it up between the board and the fan like the resistor from a noctua fan....

EDIT: Actually eaglespeed i just re-read your first posts and was struck by the PCH temperature you reported.
49-55 C is actually quite hot...(low 30s is normal with low fan speed) I wonder if something is not seated right...like the heat spreader is detached from the PCH....55 would be a temperature with no cooling at all. Still OK but not ideal. I would dismount the fan and check the contact/thermal paste etc.

the fan has been unplugged for more than a month now, and I have 140 fan blowing right at it all the time ( case is NZXT 810 switch, and my temps are very reasonable, am starting to collect cash for water cooling the motherboard and processor, and maybe after a year or so I will also watercool the graphic cards, cuz I won`t be overclocking right now.

...my first post here :p
I somewhat recognize this issue. I had it the first time cranked up my system after building it and if i remember correctly
there was a connection/molex not seated properly...
Check your connections and verify all are seated properly, maybe you missed something... just a suggestion :)

thanks for taking the time to help in this :) would you please be more specific about the connection, are you talking about the fan connection or another connection ?

Well this is sometime ago on my first crank up on my build so i will try my best :)
...first i remember that i had my graphics card connected with 1x 6-pin connecting (didn't know then) when it needed 2x 6-pin
connection and the fans went full speed and very loud, until i connected the 2x 6-pin then the issue was solved.
But after i rebooted i could hear the PCH fan also going loud so i turned off the system again and check all connections and
found a few that weren't seated properly to the motherboard. Now this i'm not sure exactly what connector it was but after that i crank it up again and at that point the loud noise from the PCH fan was no more :)
Hopefully this gives you a hint on something, but i recommend you check that all connections are properly seated and also
check that you use the "right" connectors. :)

thanks alot, you kinda give me ahint about a how graphic card fans go to full speed when there is a power problem, so a motherboard might be similar, I will give this a try tonight and report back.

unfortunately not, sold it with my computer case and other components and switched to an micro-ATX GTX 670 4gb SLI system with a rampage iv gene and a core I7 4820k, it was disconnected all the time and never had an issue when my case was well ventilated.

Such a shame, I think this is a bios error as they have addressed it once in the bios updates after the ivy bridge release, the bios indeed needs fixing its buggy

if your planning to keep the motherboard for another couple of years then seriously consider watercooling your system with a full water loop or the chipset and processor, won`t set you back more than 500$ and will run your system super cool and quiet. the only reason I havn`t done that myself is cuz I don`t live in USA so parts here aren`t available and god forbid something goes wrong I won`t be able to RMA anything. I think it`s a bios problem as well but I have been waiting for too long for a fix so I just unplugged it and moved on with my life.
