My new PC is very loud!

Guest · Oct 20, 2015

Hi, I just recently built a new PC with these specs :
Dark Rock 3 CPU Cooler
i5-4690K
MSI R9 390 8gb GPU
8gb 1866 RAM

I'm using the coolermaster n300 case and for some reason the right side panel is almost hot to touch, the temps are okay (70c cpu under load, 75gpu under load using MSI's automatic fan control) but the fans are extremely loud and like I said the case is hot!

I'm only using the case fans that came with the PC, would it help if I installed more?

Thanks! (And yes it was my first PC build ;-; )

EDIT: it only gets super hot and loud when im playing games, however it's still a decent noise during light use too

Need a little more info...when you mean right side do you mean right side when looking at the front? What kind of PSU? What speed are your fans running at (case, GPU, and cooler)?

Sapphire Thunder · Oct 20, 2015

Are you sure the cooler is properly seated? Or the thermal paste is properly applied?

For that gpu, it is very normal to get to 75-80C.
Radeons are always very hot cards since they go at full performance even under smallest load.

NVidia's GeForce gpus do not. Especially the new Maxwell gpus. They adjust the clockspeed as needed.
And due to lower heat output even under full load, they can be kept cooler.

oops didnt mean to click add as solution, anyways i'm not sure what my Case fans or CPU fans are running at here's a picture of Open Hardware monitor https://gyazo.com/1d7566d4ca344e822152713e1fb9688d

Im using a 750W CX Builder Series 80PLUS Bronze PSU and I mean right side from the back of the case, behind the motherboard where im running my wires is nice and cold.

Sapphire Thunder :

The CPU Heatsink and paste are properly done, however the fan had a bit of a workaround to it in that it's pointing almost backwards toward the vent out (the heat still leaves just doesn't go around the PC). I'm not too worried about the temps of the pc's hardware, just worried about how hot the case it to touch and how the fans make so much noise

Sapphire Thunder · Oct 20, 2015

From that pic, it can be seen that your gpu fans are spinning at over 50%, they are for sure one reason for the loud noise.

+ CX power supplies have quite noisy fans. Not to mention some have bad bearings which causes even louder noise.

Sapphire Thunder :

Thanks for the reply, to be honest i'm not overly worried about the noise, it's more the heat i'm scared of. Would adding more case fans (currently only using the two the case came with) help at all?

KidA39 · Oct 20, 2015

Not the best power supply, considered Tier IV (http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html). I suggest looking to upgrade and see if that fixes the heat. How is the PSU seated, is the fan pointed toward the bottom and pulling air in from the outside? Also, as far as the heat issue goes, what's your case fan setup? And I agree with Sapphire Thunder, double check your cooler placement.

That GPU fan is running pretty high which may be your noise culprit. If my GTX 970's run that fast there's definitely an increase in noise. Are you using MSI Afterburner to set a custom fan curve?

Guest · Oct 20, 2015

KidA39 :

I have been running afterburner recently, although even before that the fans were pretty loud. I have the PSU fan pointed down yes. I can take a picture of the PC if that would be any help. Without afterburner fan curve while playing games the max the gpu fans go to is about 45-50%. I should mention that there's almost a buzzing sound from the fans (not the standard whush noise) when it's under a bit of load, is that normal? Also would it be okay to run this PSU till december or february? I spent all my money on the build and can't really afford to upgrade it just yet.

Sapphire Thunder · Oct 20, 2015

Take an empty paper towel tube and while the noise can be heard, listen to your cpu cooler, gpu and PSU one by one to pin point which makes the sound.

If it comes from gpu or psu: it might be coil whine
If it comes from cpu cooler or psu: it might be fan bearings

As you can see, PSU fits in both categories.
This is why it can be the biggest suspect.

GPU can have bad fan bearings too though.

KidA39 · Oct 20, 2015

If you can't afford to upgrade then I guess you'll have to deal with the PSU til you can. Haven't necessarily ruled out other culprits in the heat so let's figure that out first. A picture would help to answer these questions but what kind and size of fans do you have, what's their placement, and are they running as intake or exhaust? Also, what orientation is your CPU cooler in?

KidA39 · Oct 20, 2015

Another question I have is is the heat consistent across the whole right side or is it focused over a specific area or component?

Guest · Oct 20, 2015

KidA39 :

Focused mostly where in between the PSU/GPU where the vent is (see pics). Also i've just arranged a return with this PSU to upgrade to a Corsair 750W RM750 RM Series Power Supply, or would you recommend a better one around the same price area?

I couldn't really tell where the noise was coming from exactly, I tried the paper roll trick but still couldn't tell, it seemed to be coming from the gpu but once again I really couldn't tell you for sure.

I believe they're two 120mm case fans

Sapphire Thunder · Oct 20, 2015

It's normal for it to get hot in that area since it is literally just few centimeters away from your gpu which in itself is going hot.

You could install a fan on that slot to be intake. That is, if it can fit one with that gpu.
It will re-direct the heat and thus even it out a bit.

Oh, and is that rear fan blowing outside? If it is, you have created basically an area between it and cpu fan where the air stalls since the fans are blowing in opposite directions. You should turn that cooler around.

Guest · Oct 20, 2015

Sapphire Thunder :

Thanks for the answer. I should be able to fit one, although like I said this is my first time building a PC so I could be very wrong. Regarding the CPU cooler, if you can see up at the top I had to install the fan in backwards, would that be an issue? (It's still pumping air out toward the exhaust/exit, just not flowing around the case like recommended.).

Sapphire Thunder · Oct 20, 2015

Oh, just noticed the arrows on the top image. Yeah, that should be fine that way. Though it would indeed be more effective if it would be on the otherside, pushing air through the cooler instead of pulling.

Guest · Oct 20, 2015

Sapphire Thunder :

Thanks again! Hopefully upgrading the PSU will make the sounds a bit less and be a bit better in general.

Guest · Oct 30, 2015

An update for everyone;
The PSU seems to have been the issue, I upgraded to a Coolermaster VSM 750 and the issue stopped, seems like it was coil whine. Still getting a strange noise that occurs randomly and sounds like a click, so i'll need to look into that now. Thanks for all the help!

My new PC is very loud!
