Hello. My case is a Carbide 500R and my CPU cooler is the Noctua NH-D14.
Both the Noctua fans and the Corsair case fans were dead silent till my PC froze up at the computer store and the guy hit the clear cmos. After he did that my PSU was buzzing, my MSI 780 ti was making a loud noise that became louder with load and all the fans were spinning too fast and making too much noise.

I sent in the Mobo (MSI G45) and the Video card to MSI for RMA. Both items that they sent back were malfunctioning. The Mobo had an issue with USB and the video card was going to black screen and other color screens every 10 seconds. Sent both back again for RMA and the Mobo they sent back seems to be good so far. At first when I turned it on it stayed in the no hdmi connected screen for 10 seconds and then booted up. Then when I shut it down it would just restart by itself 5 seconds after shut down. I fixed this by draining the power from the mobo and hitting the cmos reset.

Right now my only problem is that all the fans are spinning way too fast and making noise. These fans should be dead silent as they were before. The 2 fans in the front and one big one on side panel are controlled by fan controller on the I/O panel.

I replaced the Mobo, PSU and I/O panel. I can't think of anything else that could possibly be causing this to happen. And the weird thing is that its happening on the CPU cooler fans AND the system/I/O panel controlled fans.

Any ideas? :(

ok I will check that out thanks. I have 5 fans connected to the motherboard. 2 are the Noctua fans on the cooler, 1 case fan on the exhaust and 2 of the fans Corsair sent me as replacements on top blowing out. The other 3 fans are connected to the Fan controller on the I/O panel.

I clicked on the link that shows what motherboards are supported and I don't see my motherboard there or anything like it.
 
What is your current component list? What is the exact motherboard model number?

Have you tried down loading the fan controller utility from the manufacturer's website?

If you can't use the motherboard to controll the fans then you are limited to aftermarket fan contoller panels for the 5.25" bays

Hey sorry I have not been able to get online for a while. Here's my component list...

Case-Corsair Carbide 500R
Mobo- MSI G45 Z87 gaming
CPU- I5 4670k
GPU- MSI 780 ti Gaming
RAM- Gskill Ripjaw 1600 8gig
CPU Cooler- Noctua NH-D14
SSD- Samsung 840 pro 256gig
HDD- 500gig Seagate or Toshiba don't remember

I've not tried to download the fan controller utility from the website. I will check that out now.
Also, The motherboard is supposed to control the fans that are connected to it but the 2 front fans and one big side fan are connected to the I/O panel on the case. The fan controller on this panel is controlling it. All of these fans were dead silent before but now I can hear them. The Noctua fans have filters on them now to keep them from spinning too fast =/ and the 3 fans connected to the fan controller make noise even at the lowest setting but when turned up to the highest setting they get really loud. It wasn't like this before, even on the highest setting the fans were dead silent.

Naw you can look up this case you will find that these fans are supposed to be silent. Like I said, before this happened, the case fans were dead silent even at 3rd (highest) setting. And I'm sure you know that Noctua fans are supposed to be silent as well.

Only thing I could think of is that my computer somehow did something wrong when he put it together.

I called Corsair and got all new fans + new I/O panel that has the controller on it and swapped it. It's a new controller but the same thing is happening. The weirdest thing is that it is ALL the fans lol. I have 8 fans in the PC currently and all 8 of them are making noise/spinning too fast :(
 
Do you know how to control the RPM of the fans? It is impossible to make that statement if you do. You can turn the RPM down to the point that the fan blades aren't moving (or making any noise). Provided that the controller is functioning and installed correctly.

The 2 front fans and big side fan are connected to the controller on I/O panel but it has only 3 settings. I can hear them on lowest setting but if I turn it up to the high setting they become really loud with the whooshing noise.

The other 5 fans are connected to the motherboard. The CPU fans have the low voltage filters on them to keep them from spinning so fast and the MSI command center shows them spinning at 700-800 or so RPMs. The exhaust fan is about the same and the 2 fans on top don't even show up.
The 2 fans on top were replacements that Corsair sent me for the two in the front.
 
Perhaps, if I tell you how I control my fans it will help you.

I have an Asus ROG Maximus V Formula motherboard, it has seven fan headers. I installed Asus Fan Xpert 2 to control the fans.

My case is an Antec P280 super mid tower case. It has two top and one rear 120mm fan. These three are controlled on a case controller set to low (about 900 rpm). All of the the rest of the fans are controlled by the motherboard. They inslde a two 140mm and a 120 mm fan on the Noctua NH-D14 CPU cooler. There are two 120mm internal case fans and two 120mm front intake fans. These last are installed using two Y splitters (not necessary but it makes thing easier) onto motherboard fan headers. The front, middle and rear CPU fans are installed to three motherboard fan headers.

The Asus Fan Xpert 2 is initialized. This measures and charts each fan on a graph (RPM vs Percent of 12 Volts). This gives you the minimum RPM and Percent (3 -5V ?) before the fan stops for each fan. If you buy good quiet fans, an RPM of around 600 rpm is nearly dead silent from my experience. Fan Xpert 2 allows you to set three RPM set points for each fan. I set the lowest setting to about 600RPM at 20 degrees C. I set the middle setting to 10 % higher and 30 degrees C, so that it brackets room temperature at a low fan RPM setting. I set the last high setting to 100% (12V) at 70 degrees C. Again I do this for each fan header that has fan (or two fans on a Y) installed.

The logic is that for the vast majority of the time, the fan controller maintains each individual fan BETWEEN its individual voltage equivalent to about 600 RPM AND a 10% higher voltage.

So basically all of the motherboard controlled fans operate at 600-700 rpm until the temperature of that particular zone exceeds 30 degrees C. Then it ramps the %(of 12V) linearly to 100 % (12 volts) at 70 degrees C.

I hear the fans (fairly loud) when the computer boots up. The as window loads the fan controller application loads and the fans go nearly silent. From 10 feet, I can't really tell that the computer is on without the case LEDs and monitor.

That sounds complicated :)

I took off the two fans at the top because they were not showing up on the motherboard even though they were plugged into sysfan 2 and 3. Also was impossible to get to the CPU cooler fan wires. I took the low voltage filters off the CPU cooler fans and the exhaust fan and plugged them in.
Booted up the PC and opened MSI command center and saw they were all at over 1200 RPM. I tried turning them all down but it only worked for the exhaust fan. I can control the exhaust fan without an issue but the Noctua fans on the cooler stay at over 1200RPM for no apparent reason. And the 2 front fans and one big side fan are still louder than they should be. These 3 are connected to the controller on the I/O panel and when set to lowest setting they still make some noise but when turned up to 3rd (highest setting) they get really loud. These 3 fans used to be dead silent at 3rd setting. The Noctua fans were also dead silent. After my PC froze at the computer store and the guy did the mobo reset everything started making noise. I had to RMA my card and mobo because of it, I had to trade him my old Sapphire 7950 for a new Seasonic 1050W Gold PSU because my old PSU was buzzing.

The I/O panel was changed but not the wires connecting it to the other parts. Is it possible that the wires are causing this? I would try and put in the new wires Corsair sent me but I don't know how to do it and the guy didn't do it when he changed the I/O panel.

Right now I need to figure out two things. What is preventing me from lowering the RPMs on the CPU cooler fans and why are these 3 case fans spinning faster than normal and making noise. Seems like such a simple problem but nobody can give me an asnwer. My computer guy keeps trying to tell me that I'm chasing a ghost and that's how it's supposed to be. I try telling this idiot that I know exactly how my computer souned before all this crap happened. It's his fault I had to bring the computer back there in the first place because he didn't see that the RAM was in the wrong slots and pressed up against the cooler fan casing. I took the PC to some chinese computer store today and the guy took a look at it and listened to it and also told me it's normal. These people either don't understand that IT IS NOT NORMAL FOR THIS COMPUTER or they just don't want to bother with trying to find the problem.
 
Sorry for the complicated answer. Sometimes my inner nerd takes over.:D I'm an analytical chemist, so it's not very far under the surface anyway.:D

Take a look at the fans power connectors. Fans with 4-pin connectors can be controlled by either RPM feedback or voltage. Fans with 3-pin connectors can only be controlled by voltage (the fourth pin is the rpm feed back).

Pull the fan connection from each motherboard connection. (Needle nose pliers or a hemostat is helpful in replacing the fan connector) Write down the number of pin holes in the connector (either 3 or 4) and note if it is one of the noisy fans. Also note what it cools and whether or not it has a low noise filter or not. And then post the list.

I think you may find that the fans that aren't being controlled by the mother board are 3-pin fans. The low noise filters are useful for reducing the RPM of the 3-pin fans. Not all motherboard fan controllers will control 3-pin fans.

All of these fans have 3 pin fans. I just can't win with this computer man. I just put in the 2nd replacement MSI 780 ti gaming that they sent me. It's brand new was sealed in box and everything. It has bad coil whine =/ . I'm also crashing in Wolfenstein and it's telling me I'm low on memory. The same thing was happening to me a few weeks ago when I was using two R9 270s in Crossfire. It only happened in Titanfall and THief, the games I was currently playing at the time but I tried other games and it did not crash. I disabled Crossfire and it did not crash again. Now I'm having that damn low memory message and crash in Wolfenstein with just one video card and it's coil whine is bad. Multiple people have complained about getting multiple replacements for the coil whine of this card and all had the same whine.

The original motherboard controlled the CPU fans and the case fans were silent as well. The original card was also dead silent, not a peep from it.
Now it's just problem after problem with no end in sight
