Side vents, blowing air out or drawing it in?

[Ephectx]

Hello, I would like to know how I should have the side fans to have a more efficient (lower) temperature in the PC in general, since my general CPU goes to 33º on idle and the cores to 43º, and let's not talk about the graphics, 50º on idle.

The thing is that I have two side fans Xilence, one of 12x12 and another of 8x8 (bringing in air, I think, since if I light a lighter it goes in, and if I put a piece of paper, it sticks) and a small rear fan that expels air. The thing is that I would like to know what is better so that the flow goes well and the temperature is kept as low as possible at all times, but I don't know, what do you think I should do?

I tried removing the small side fan and leaving only the big one and mysteriously the temperature dropped from 33º on idle to 26-27º, the same with the other temperatures. But I put it back in just in case, is it normal that they drop?

PD: My computer is a Pentium G840 at 2.8ghz, an HD 5850 Xtreme, 4GBS Kingston DDR3, an h61m-s2-b3 motherboard and a Nox Urano 600w power supply, the case is one very similar to the 'ATX MEDIATORRE NYX NEGRA 3.0 NOX'

PD2: There is a temperature that bothers me a little and it is that of the "PCH Diode" which is at 57-58º.. is that normal?

I hope you can help me, thanks in advance!

Hello and welcome

Those temperatures are not bad at all, but the ideal distribution of fans in a tower (depending on the tower) should be more or less as follows.

Recommended:
-1 or 2 12 fans in the front bringing in air
-1 or 2 12 fans in the back pulling out air

Optional:
-Some fan on top bringing in air (depending on whether there are many cables inside and if the tower is small)
-Some fan on the side bringing in air (if the graphics card gets very hot for example, one at its height cooling it down)

Best regards

The temperatures are good & winter is coming :ugly:

The 8 fans are crap, I would throw in a 12 front and a 12 rear, more than enough considering the temperatures.

Those temperatures are not bad. Basically you must enhance the chimney effect. That is, take advantage of the natural tendency of hot air to rise, so that it stays inside the case for the least amount of time possible, and prevent everything from condensing inside.
All the fans you have from the middle of the case downwards should blow air in, and the ones that are from the middle upwards should blow out the already hot air. Also, if you have one blowing air to the graphics card, it will improve its temperature or at least reduce the noise, because it will automatically lower the revolutions of its fan.
To improve the air flow/noise ratio, the best thing is to have the fans as large as possible. 14 cm is better than 12 cm and infinitely better than 8 cm.

Best regards.

But the rear fan only fits one of 8 and in the front I have one of 12 in the graphics part blowing air, above, in the micro part, I have nothing, it's better this way, right?

Edit: removing the side, the temperatures have generally gone up xD

Well, if there is no space, then there is no space;D... what can you do.
At the top of the case, if the case is not prepared to extract air from the top, then there is nothing you can do. But if you have the possibility to put a fan that extracts air, then it's better. The ideal thing is that fresh air enters through the bottom of the case (through the front, fans at the base of the case or sides), the fresh air circulates throughout the interior of the case and the already hot air is expelled through the top of the case (rear and top of the case). It is normal for the temperature to rise when you remove the front fan, when you introduce more cold air, you force the extraction of the hot air more, which is the weakest point of your configuration.

Best regards.

if you have a 12 in the front and an 8 in the back, the best thing is to put the one on the side by removing
and not putting

[Ephectx]

So what do I do? Do I remove both? Is it really better to put the side one out? That would leave both out, side and rear (plus the front one), wouldn't it get hotter? xD

[ferelxyx]

if you put in more air than you can take out, it gets hotter, because the hot air circulates around the box
it is better to have more taking out than putting in and that the ones taking out are as high as possible, because the
hot air always rises

regards

[Ephectx]

But, I have one in the front blowing at 12, and then the rear at 8, so do I leave the side at 12 blowing or sucking in air? I'm not sure about that.

[ferelxyx]

better to take out the 12, it lets in twice as much air as the 8 can
and it also removes the hot air from the graphics

regards

[Ephectx]

With that, would the temperatures of the processor and other components also decrease?

[Sylver]

+1 to the side shot, better to let out more air than you let in.

P.D.: The processor temperatures depend mostly on the heatsink and the thermal paste you use. The ambient temperature also influences, but less.

[Obione]

Well, that's it, +1 again at just 12s, lane 12 exiting and 12 entering. I already told you that the temperatures are good and it's not worth having one at 8 full throttle, it's killing morale xD

I haven't had time to put the side panel off, but with it on, it's not too bad, at idle they are usually "good"

General CPU (tcase): 27º
Core 1 and 2 between 28 and 42º
GPU DispIO, MemIO and Shader over 45º
Motherboard at 35º
HDD at 37º

At idle, do you see them as good? or would they be better with the side panel off?

I would try it out, after all, it's only four screws.

Well, the information in the Spoiler is for the more experienced.

! Pulling or pushing? Man, the ideal is to push and pull, laterally or frontally can vary with tastes.
! It is also interesting to have a large fan, although sometimes having a fan that is too large can be a drawback (that it does not fit, let's say).
! But for most towers, the ideal is that the air moves gently from front to back and as quietly as possible so that the cooling goes unnoticed by the neighbors.
For Ephectx, I already see many answers, and if there are more doubts, there is nothing like a photo to cut to the chase.

Now, it's not that hard to understand:

• priority 1: EXTRACT hot air from the case
• priority 2: BRING in fresh air into the case
• priority 3: make as little noise as possible

And that sums up, looking at your current temperatures, to:

• 12cm fan on the side blowing air out
• 12cm fan on the front bringing air in
• 8cm fan on the back at minimum RPM (and if not possible, remove it directly).

Also, temperatures appreciate a minimum of organization in the wiring, so as not to affect the air flow inside.

[edit: spelling]

[Sylver]

Uhriens man, it is preferable that the one at the back stays, so that the airflow is as straight as possible. Only with the 12 on the side, the hot air can give it many unnecessary turns inside the box, everything that is to expel hot air in the same direction that it enters, although it is a task shared, interests him.
