4770k + Noctua NH D14 fan speeds...slow

Hi!

I've just put together my PC and my fan speed is incredibly low.

Is there any way for me to control my D14 fans? I am idling at 40~, which seems to be way too high!

You probably put too much thermal paste. Try reseating the heatsink.
And there is, depends on motherboard if you can contorol it in BIOs...and also where you connected them. And SpeedFan allows you to control fans RPM.

Go into the BIOS and change the fan profile.
You will find more information in the motherboard's manual.
What motherboard do you have?

ASUS Maximus VI Hero.

I am not really sure where I plugged it in. I used the connectors that came with the fan and put them in the slots labelled CPU_OPT and CPU_FAN.

Really a shame if I have to reseat! That took me so long, lol.

If the board does things properly 40 C is a fine idle temp... anyone who cares about idle temps doesn't understand how little they mean. Load the thing up and see what happens. No reason to worry until you know load temps your board may just keep fans nearly at minimum temp until 40c. that processor can hit 100C and not hurt itself.

For the ASUS board, change the fan profiles to 'turbo', either in the bios or in the windows fan-expert utility.

Seriously? It does matter if he is not overclocking and did not change his load line calibration and voltage. 40*C on idle from nothing is a big deal, that means under load it would hit ~80*C

With that motherboard, you get Asus Suite which comes with thermal radar. And that allows you to change fan profiles in Windows. But 40*C really seems like a big deal if running stock settings.
I hope you used the grain of rice method with the TIM and didn't smear it all over. (Unless using Tuniq)

Edit: And just because a CPU can reach 104*C, doesn't mean you should allow it to go that high, it will cause stability issues and other problems as well as possible degrading.
With that CPU I'd keep it ~80*C highest, and not get into the 90's.

I tried to run Speedfan and it just straight up gave me what I think is the 8.1 blue screen, complete with a smiley face. Changed to Turbo and for some reason my USB devices did not work right on startup, which was odd.

Try updating you MoBo BIOS, may fix some issues your having.

We also need to know what the ambient temperature in the room is as well. For example if the room is 35degC, then 40 is really good. But if it is 20, then 40 at idle is a problem and indicates something is wrong; case airflow, paste application, or sensor errors.

Isn't updating my BIOS somewhat risky? I don't have anything to test the temperature, but I do not think it is that warm. There is snow outside.

Also.. I can't seem to find Thermal Radar. It wasn't on my motherboard disk and for some reason I can't find a download link.

Maybe a tiny bit but much less so if you do it from the bios, and not while in windows.

There is risk in just opening up the case..
Read the release notes for the updates. If it addresses a problem that you are experiencing, then it is well worth the effort.
Yes, there is a small risk, but I have never personally known anyone who has ever experienced a problem.

I will try the BIOS thing last.

I am worried that Speedfan is just straight up blue screening me. I do not know how to see my RPM =P

What is the thermostat in the house set to? That will be close enough.

23~ degrees. After updating to Turbo on my BIOS it seems that my temperatures are actually worse. I'm sitting at 1-5% load and 40-44 degrees.

Are both fans on the radiator directing air from the front of the case, directly towards the rear case exhaust fan?
All three fans need to be moving air in the same direction and almost exactly in line. Check to make sure that one or more of them is pushing air in the wrong direction.

I am not exactly sure how to check that. It goes:

Fan on the case > fan on DH-14 > radiator thing on DH14 (?) -> fan -> radiator thing.

I did mess with the fan configuration to get everything to fit. Could I have put the fans backwards? How do I figure that out? lol.

Should be an airflow arrow on the fans to indicate which way they will send the air.

I don't see any notification on them.

This isn't my rig, but they look like this: http://img.techpowerup.org/091205/IMG_0118.jpg

One thing I notice that's different, is in this picture the latches that latch onto the radiator are latched onto the left side. Mine are latched onto the right side.

I don't see how I could put the other fan on wrong, as there's no way to change what side the latches are on (I think), so i would have to attach it that way.

I'm not even sure what model that one is, just the only picture I found that is what mine looks like.

I also did some googling and I think I used the wrong fan connectors, but I do not entirely understand which fan connectors I should have used. I used the ones that came attached to the fans.

If you used the LNA (low noise adapter) or the ULNA (ultra low noise adapter) then that will slow the fans down. Take them off if you used them.
Plug each fan into the CPU fan and CPU_OPT fan headers on the motherboard. Don't worry about the 'Y' splitter.

On my NH-U12P SE2, the fans have a embossed arrows (raised images the same colour) on one side that indicate blade spin and air flow directions. It is extremely important that they are all pushing air in the same direction. Including the case exhaust fan at the rear of the case.

The D14 is arguably one of the best air coolers on the market, and at idle, should keep your CPU almost the same temperature as the inside of the case.

Thanks. I will check it out later. Both sides I can see do not have a raised arrow anywhere, so they must be on the side that is facing the MoBo.

I really have no idea which connector I used. I can't check now as I'm in the middle of a transfer. I used the two connectors that were attached to the fans. I think they were white and had three connectors on each so that there was one pin not connected and I put them on CPU OPT and CPU FAN. I did not attach anything to them. It would seem really stupid for the default ones to be the LNA/ULNA connector. Have any pictures of what the ones I should have connected look like?

There are big brown stickers wrapped around the wires saying "U.L.N.A. Adapter". If you didn't plug anything additional into the wires coming out of the fans, then you didn't use them and they are still sitting in the box.

You can use your hand to feel, or the easy way. Fans blow towards their mounting hardware, so the side with the sticker on the motor is the side where the air blows out from-and in from the other side.
Hard to word it without demonstration, so I hope you understood that.
And BIOs update is super easy with your motherboard because it has recovery if anything happens. Just take a usb drive, put the BIOS on it and follow the instructions in the manual.
For optimal airflow, for most situations but vary, you want slight positive pressure to reduce dust build up. (It acts as an insulation for heat)
So bottom, front, and side intake, and top and back exhaust. You'd want the Noctua's in push pull, so they blow air in the same exact direction to exhaust the air out of the case.
Heat rises-this is why this setup works ~95% of the time.

and please don't say you don't have a side fan if you don't this does not mean this set up is not optimal-just means you have slightly less airflow.

Another thing plausible is Airflow choke. Not enough airflow for the cooling solution so your cooling is limited.

Thanks again, you have been very helpful! I did not use any external connectors, so I should be fine with my fan connector.

Just to get things straight for when I try this later, I want to have it setup like:

<-- Fan on back of case <--air--- Noctua fan#1 <--air-- radiator <--air-- noctua fan #2 <---- radiator.

I still do not understand how to change my fan speeds, though. What RPM should they be at anyway?

I've had P95 running on default settings for 10 minutes now and my temperatures seem to be between 65-74 (First three at 70-74, last one is 66-70). The load is 100%. This actually seems okay so far, does it not?

Yes that is a very good temp for Intel CPU's.
You have an Asus Motherboard, so if you go to your motherboard on the Asus website, and click Support near the top right.
Then click Tools and Drivers.
http://www.asus.com/us/Motherboards/MAXIMUS_VI_HERO/#su...
Put in your OS.
Click-I think it'll be utilities. And download Asus Suite.
It comes with thermal Radar, and with this, you can control fan speeds. On your Chassis as well as your CPU fan.
