H100 Fans Stuck after OC


Troj

Recommended Posts

Hi Everyone -- I did a very minor OC on my 2600K (4GHz - 4.2 GHz), and the H100 fans jumped to ~3800 rpm. At 4 Ghz the fans never went to this speed.

 

One of the fans also keeps ramping to max, then cutting off entirely, only to repeat this cycle every 15 - 30 seconds.

 

The LEDs do not light. The icon in the lower right hand corner is lit.

 

The H100 is plugged into the MoBo. MoBo is Asus p8p67 Pro. This worked before the OC.

 

I reset chip to default 3.4 GHz, but the H100 fans are still stuck. I also tried holding down H100 profile button 5 sec when computer was on, letting computer stay on 60 sec, shutting computer off, turning it back on while I pressed profile button 5 sec. Still no changes.

 

Any advice? The fans have never done this before, but for some reason the minor OC at 4.2 GHz caused them to start in on this maxed out cycle. It's pretty loud too.

what kind of fans are you using?

 

no stock fan is going to run at 3800 rpm

 

just looked up stock fan max is 2600 so your using other kinds of fans

 

That's what I think too, but I'm only using the H100 fans that I purchased. Maybe the numbers are way off, which is no doubt a possibility. This is really baffling to me. I went into the BIOS and reset everything to default too, so I don't know why the H100 fans are acting this way.

 

Both of the H100's fans spin on max, even when the system is cold. One fan will stop spinning for a few seconds, and then start again. This cycle repeats every 15 seconds. The H100 fans are plugged into the MoBo, and they were before too, and the fans didn't do this.

sounds like you may have fried the controller from a voltage spike,,assuming you followed the reset procedure and it appears you did.

try unplugging the usb then replug while its hot

 

I'm afraid you could be right. I went into the UEFI and see the CPU Fan speed at 3782 (Asus AI shows fan speed at 3792). I'm not sure what you mean by unplugging the usb? I apologize. I'm new at building rigs and totally new to fixing errors. How would I tell if I fried the controller to the H100? Or did I fry something else? If it's the H100, would I need to replace it?

 

Thank you for your reply. I hope I'm not damaging my system in any way. Asus AI shows the cpu temp at 34C, so at least I'm not superheating anything if I can still believe the numbers.

 

btw does it matter that the LED lights no longer work? They're all dark, and pressing the profile button does nothing for them. The icon on the bottom right is on though. That never switches off.

the h100 has a controller that handles the fans and such,the cable that goes to the usb header,while the computer is running unplug and replug it,of course dont touch any important part.before doing this you can try plugging to another port while the unit is off.

are you referring to the little man icon on the hydro?

are you using the link commander?

try doing a couple resets

I purchased the H100 two years ago. It's a basic unit and has only several cables, which all plug into the hydro. My H100 doesn't have a usb header or a link commander, at least not that I know of, and when I installed it two years ago, I don't recall seeing or dealing with anything similar to the link controller images I see on an internet search right now.

 

Yes, the icon is the little man on the hydro. I unplugged the pin that plugs into the cpu-fan on the mobo, but the fan stays on. IIRC the mobo doesn't control the H100.

sorry its late,no theres no usb header but if the little man icon is all that lights up then its like its not using the 3 profile function but is in the link commander mode which you stated that you dont have,really all you can do is try resetting the unit,try it a couple of times

I gave the resets a try. I did about 5 resets, but nothing's changed. I have the Corsair 600T case Arctic White, and I turned down the fan control knob, and it doesn't effect the fan speeds on the front or rear fans. The LED light is on in the front. Nothing in the back though. I'm fine with replacing the parts, but if you might be able to tell what's going on with my rig, I'll know which parts to replace.

 

Thanks :)

huh?

are we talking about your h100 or your case fans?

ahh,let me see your 3 profiles arent working because your fans are on your case controller,is this right?

 

The H100 fans are stuck on high, and the sensors show hem to be spinning at 3800 rpm. I wondered about the Corsair case fans after my last post, so I tried turning the case fan control knob to min and slowly to max. The case fans spun at the same speed regardless of the case fan control knob.

 

I'm not sure why the hydro LEDs don't light up. Now I'm really puzzled. I have H100 fans stuck on high, and shouldn't the 609t fan control knob on minimum slow the fans down?

 

Thank you for your time. I wish I were more knowledgeable so that I didn't need to ask for so much input.

are you running other monitoring programs like ai-suite,real temp,core temp ect..? if so shut them off and try things,if this isnt an issue i can only think the hydro is cooked.

considering pump speed is high its probable that other programs could be interfering.

Those are the only programs I've run. I don't think they're an issue because I can't access fan control speed from them. If the hydro is fried, I'll replace it. What do you think about the case fan control observation? I read where this only controls voltage, not rpm. I'm not sure though. If I turn it down to minimum, shouldn't my two other case fans spin much slower? If I have to replace that control unit, I'll do so, but please let me know your thoughts.

sorry but your misleading,explain in detail where all your fans are hooked to,what programs do you run in regards to monitoring ect..

 

My apologies. The 600t has one fan at the upper rear and one in the lower front. These fans are hooked to the controls for the 600t itself. It's been over a year since I put this rig together, but the 600t front and rear fans were never connected to my mobo.

 

The H100 is connected to my mobo CPU-fan port.

 

The problem now is that

 

1) the H100 fans spin only at max, with one of the two fans shutting off every 15 seconds only to restart and go to max for about 60 seconds. The rpm for the CPU fan shows 3870. The LEDs on the hydro do not light up. Only the man icon does. I have no idea why, and I remember that the instruction pamphlet for the H100 installation had close to zero information. I can't answer what I don't know, which, to my frustration, seems to be more and more now.

 

2) I don't know if the case fan control even has an issue, but I do see that turning the case fan knob from min to max does nothing. The LED blue light is on in the front case fan. The rear case fan has no light.

 

Before my OC this morning, everything was running fine. I changed nothing in the rig. Now I have fan issues, so I thought I'd see what the best explanation for these issues is, and what I'll need to do to fix this. I've run CPU-z and asus ai to check temp, speeds, and voltage. I went into the efi to check these as well. They all state the same high CPU fan rpm.

 

Thank you for your patience.

when the clock speed is changed bios could have made its own changes to accommodate the oc,go back to basics and reset your bios and see how things go

also ai-suite WILL NOT work in conjunction with the hydro so stop these type of programs when checking

as far as the case controller i cant really say without using a volt meter to check its increments of voltages.

ill be here tomorrow if i can help further.

Good to know wytnyt. I reset the cmos then went int efi and set to f5 the default settings. Unfortunately nothing has changed. Is there something in particular I should check in the uefi now?

 

Thank you for spending so much time. This has to be wearing you down. I appreciate your help, information, and patience.

im just going to say i think you either installed some program that messed it up somehow or its just a complete coincidence this started happening...you reset cmos settings...so nothing in the bios could still be causing this problem

cmos is a technology for constructing integrated circuits and maintaining circuits when in a windows environment,with current processors and informative software Oc'ing has been made easier but with it comes untested risks to systems, meaning most anything can occur.

id make sure bios was reset,all monitoring programs are off,reseat your cables to the hydro ,reset the hydro and try things.

if this doesnt help,try hooking the power to the hydro to another computer and see if the profile lights work.last resort is to rma it.

Thank you wytnyt. I'll try this but am more inclined to purchase a new cooler. I don't have anothey system to test out my hydro, so it's just easier to replace it. btw how are the H100i? Any other cooling recs for the Corsair 600t case? Also I did a CMOS reset and the jumper fell through my computer and now I have to get new one. XD. This has been an experience! I look forward to your replies.

 

Thank you Bryman as well :)

aint been your day has it?:sigh!:

the h100i is a good cooler ,im running 2 of them and am quite happy with them,it also of course is integrated with the link ,where you can have better control and monitoring of your system

I just bought the H100i and some jumpers caps, so I'm ready to go. The sales rep who builds a lot of rigs confirmed your suspicions of a fried controller in the H100. Apparently if only the person icon is lit and the LEDs won't light the cooler thinks it's on manual.

 

I think I can rma the H100 I do have, so I'll try and see.

 

I'll look into the link. I think it'd be great to have. I love Corsair, so I'm happy getting another.

 

Thank you for your help! It wasn't my day, but I learned a lot, so I'm happy.

 

Have a great weekend!
