How should I configure my rig for optimal temperatures?

post #1 of 18
Thread Starter 
I've got a bunch of components here and I don't know how I should set everything up for optimal temperatures, I would love to get some advice on this.

First of all, these are my fans:
  • 2 * Noctua NF-P14 FLX 140mm 1200rpm
  • 2 * Noctua NF-S12B FLX 120mm
  • 1 * Fractal Design 120mm Silent Series

This is my fan controller: Scythe "KAZE SERVER" Advanced Fan Controller

This is my CPU cooling: Noctua D-14

This is my Case: Fractal Design Define R3 White

Fan setup

I have the two 120mm noctua fans running at ~1300RPM pulling air into the case from the front.

In the back I have the Fractial Design fan pushing air out of the case

On the side ( door ) I have one of the 140mm noctua fans pulling air into the case, somewhat blowing directly onto the motherboard.

On the top of the case, the rearest one, there's the last 140mm noctua fan pushing air out of the case.

The CPU cooler is aligned so that it pushes the air against the Fractial Fan.

The CPU fans and the fractial fan is connected to the fan controller that came with the case.

The other fans are connected to the fan controller.

I would like to run my fans at a quite lower speed, because the door/side fan makes a lot more noise, don't know why. But I still want to keep the system cool and nice. The fan controller from schyte have built in "temperature"-control so I can have it running in semi-auto mode, I haven't figured out how yet, suggestions on that?

I'd love to get some feedback on how I can reduce my temperatures/how I can align everything to optimize the air-flow. Maybe I need any additional fans or remove the fractial design fan?

First of all, test temps with your current setup.

Then:

1. Close off the rear top fan position. Set up the forward top fan position for intake.

2. One bottom 140mm intake fan.

3. One side 140mm intake fan.

4. Two 120mm front intake fans.

5. No rear fan: cut out that grill to allow air to simply flow out.

6. Next to each video card, leave one slot above and two slots below without covers. This will allow air to rush out next to the vidcard(s), ideally with a little constriction to accelerate the flow.

7. Use a mid-case fan only if you have a spare 120mm. Certainly with your case you likely won't hear it.

You won't need a rear fan, and its absence makes a quieter rig.

If your rig shares your desktop with you you will want that side intake fan running at lower speed to remain quiet. If you have it on the floor, go ahead and let it run full speed. It's not loud.

Then OC away.

What a nice case you have.

Wow thanks a lot for that! I've been running prime95 for 15 hours and the max temperatures have been ~79 celcius.

The image you have over the fan setup, is that my case?

There is a 120mm fan in the center, behind the gfx, I don't think I have anything to mount that on in my case. ( guess it might just be an illustration )

So I should close the rear top fan position, you just don't mean remove the fan but to close it?

I have the computer standing on the floor ~1 meter from me, the fan on the side makes quite a lot noise, maybe I've mounted it wrong?

Will cutting the rear grill out improve the airflow a lot?

Thanks so much for this great response! +rep!

I think I got the temperatures down a bit.. Thanks a lot! And it doesn't make more noise than a standard table fan does.

No. It's mine. Your case is better.

That mid-case fan is held up with two zipties in this pic. My current setup has it held up with a single ziptie. It actually pulls air through the open portion at the front of the case and bestows its largess on the PCH and the vidcard.

Go ahead and remove the rear top fan. The less clutter the better. And yes: Close off where it was.

Maybe. Try these. But most likely you just have a loud fan. If you need to, this can give you 5 Volts for a case fan. (I love SVC's free shipping on these.)

It will improve the airflow somewhat if you put an exhaust fan there. But if you put no fan there you will get a wonderful silent exhaust: no fan to make noise, no grill to impede outgo. It all just flows like a river, quiet and strong.

So what steps did you take to get it this far?

It makes a little bit less noise than before, it's not very silent even though I only have expensive "silent" fans in it. But the temps are OK.

Don't know yet if they are better than before. They are OK, the system are less noisy and temps are around what they were before. If I can get the GFX fan to make less noise then my setup is complete!

Edit

It's the GFX fans that makes the most noise now. So I guess I am happy.

Wow the temps are actually a lot better.. I've got almost all my fans running at ~900 to 1050RPM which is a lot less than before and I didn't go over 77 celcius ( only one core peeked at that! ) after ~5 linx runs. Which is really good.

I'll take a shot of the case later and show you my setup aswell. One of my sides are filled with cables and REALLY hard to close
