Fan placement i FD R4

post #1 of 18
Thread Starter 
Hello!
I just put togheter my new rig, and i need some more airflow in it. This is the setup i have now:
2x Fractal fans in front as intake
2x Corsair sp120 in push/pull with a H70, as exhaust.
So, i have 2 140mm slots free in the top, and one 140mm in the bottom next to the psu. So my question is, how many fans should i put in it, and where should i place them? Should i go with one i the bottom and two in the top for exhaust along with the push/pull exhaust?

I have 5x of the noctua uln 140mm:

2 front intake
1 back exhaust
1 bottom intake
1 side panel intake

With a dh14 with a 2 fans blowing air towards rare exhaust.

What are your temps?
Did you remove the HDD cage or is it still in place?
What GPU are you using?

I7-3930K 6 cores = avg 40-44 during normal operation
GPU = Asus gtx 680 top is between 36 - 38

HD cage still in case. I rotated it, then rotated it back. Maybe I should just take out the whole thing. I have 3 mechanical drives in the bottom one. One SSD in the one

Those temps are fine but need to know what the load is. Would be better to know what your idle and stress test temps are. What speeds are you running your fans at?

Removing HDD cage allows air to flow from front fans better. Less restriction.

Under a 100% load
CPU is between 63-70
GPU is 70

D14 fans 850 and the second is less than 800 rpm
Case fans are about ~700

GPU fan @ 1860 rpm is the loudest component

Keep in mind that H70 is not near as good as big twin tower coolers.. like 7-10c hotter.

63-70c@850/800rpm is OK. I would speed to fan up some.. like 900-1000rpm and you will see temps drop a couple of degrees.

Bring case fans up some too.

I assume your GPU @ 1860rpm is at full load and it idles at lower speed?

My goal is to keep this setup as quiet as possible.
And using the Ai suite from Asus, I have tweaked the fan speed settings to be as quiet as possible during normal operation. The GPU fan speed is usually 1050-1080 which is 20%. And thanks to the bottom fan, that is achieved.

Noise levels are pretty low during normal use.
About 23-24 dba.

Thinking of adding the artic accelero hybrid GPU cooling solution.

Or maybe a water cooling solution...

Understood.
I suggest getting a cheap indoor/outdoor wired remote sensor digital thermometer. Mount the sensor in front of your CPU cooler to see what the air temp going into cooler compared to room temperature is. Do the same with your GPU.

I have had good results in sound and temp but removing the stock GPU shroud & fans and replacing them with 120mm PWM fans (have to make a custom adapter to connect to GPU and PSU).. or something like Arctic F12 TC fans (temperature control with remote probe).

What are your temps?
And fan speed?
And noise level in dba?
