Duda fan for case

[Xtreme-HD]

Well, from my experience, the bigger the better?

When you have a large size, you have to keep in mind that they generally won't go over 1000 revolutions, the normal I think is 800 if I remember correctly, the good thing is that they have a lot of flow (which is basically what ventilates), for example, recently I put a 40 in a box, it consumes 12 dBI at full capacity but it had an incredible flow. The average temperature dropped by more than 6º

If you put several 12 fans, you will have less circulation flow, and a lot more noise.

EDIT: I'm looking and I can't find anything in Spain, the best I see is from the brand Tacens and its 25cm fan... I think if you want to cool from the side, you'll have to put a 12 or get one of 25.

Neither more revolutions nor fewer, it all depends on the needs.
And as they tell you, the bigger the fan, the less noise (fewer revolutions) and the more airflow you will have, now of course it will all depend on the maximum size you can put, a 23 cm one would look great but if you can't put it then it will have to be a smaller one spinning faster and making more noise.

Now if your doubt really is how much ventilation would be necessary for your tower that is another issue.
It depends a lot on the internal components of your pc, but as a minimum one of 12 in the front bringing in air and another at the back taking it out, the 12cm ones at 1200rpm still don't bother you and already move some air.
If for example you had a 22cm one at 600rpm you would have less noise and more airflow.
If for example you had a very powerful micro and gpu (or several gpus) and a lot of everything inside the tower, then with two of 12cm @1200rpm I think the tower would not be well ventilated during video game sessions and things like that.

If you tell us what the tower is and what components it has we could give our opinion on the best solution for that tower, it is not essential to have many rpm to ventilate the tower well.

Salu2.

PD: If you have doubts about whether your pc suffers from heat the first thing is to monitor all temperatures by software (coretemp, speedfan, etc etc.)

Thanks for the replies. What a level.

The case is a Nox NYX, it has a 12cm fan at the back, and it's for mounting an i5-3570 and an HD7770 that the forum mates recommended for graphic design.

I know the case is not great, but it has front USB3.0, and above all, because of its dimensions, it fits in the space where I have to put it, 20 x 45cm.

I wanted to change the original fan for a quieter one, because I think the case is quite open.

Regards.

If you put the tower in a cubicle of 20 x 45 cm, I hope you have the air conditioning on all summer.
And that it's a space that doesn't have the bottom covered.

About the tower you want me to tell you, you could choose another one you like but that has the power supply at the bottom, or if not, one like that but with a fan with good intake in front of the drives.

[tigre_est]

Yes, the back hole is open.

Ok. I will try to find one with the font down.

Best regards.

Well, the thing about the bottom fan is mostly so that the tower can have an extra fan on the roof, so you don't have to rev up the rear fan as much when there are two in the same corner, and since you're going to have the tower boxed in on the sides and they often don't come with a decent front fan, if there are at least two pulling air out of the top rear corner, there will be more efficient hot air evacuation. I don't know if you've seen any forum threads about tower ventilation yet, but the ideal for any tower is to have at least one fan pulling air from the bottom front and another pushing out the back where yours is, and since in your case it won't matter that it sucks air in from the sides (which will be blocked) the basic front-rear fan setup would be ideal for you. It's not that your hardware is particularly hot or anything, but if you're going to be video editing you'll want to help the case air circulation a bit. Oh, and by the way, the stock CPU cooler is sufficient if you're not overclocking, but I imagine it'll be the fan you hear the most when you're really pushing the CPU, but you can always replace the cooler whenever you want if you find the hum bothersome.

if you feel like doing some DIY this one is pretty good http://www.tienda-traxtore.com/tienda/index.php?page=pp_producto.php&md=0&ref=VEN556 to place at the top or bottom of the tower

@tigre_est:

Hello, I would like to ask you a question. For placing it in the case chassis, what is more suitable, a fan that goes to many revolutions or to a few?

Could you make me a recommendation of one that is silent and not very expensive?

Regards.

Hey how are you I'm new to the forum, I think you also answered the question about the 7770, the case is nice, but I would recommend looking for a case with the power supply at the bottom. Here's a video I made where I talk about some things about airflow.

Another aspect you need to consider is regarding air pressure, in this case, since it's a fan that will take air that is inside the case and expel it, the truth is it won't make much difference. A fan at decent revolutions like 1600-1800, wouldn't be bad, or look for a PWM fan (in case you have a PWM connector on your motherboard, so you can control it, and you can buy a fan that spins fast, only at certain times). Or you can also buy a high-rev fan and you can do this small mod:

So that your fan doesn't spin so fast. But if you need it, you can have it. I don't think a fan located at the back will make much difference (that is, the type of fan), in any case, the ones that affect the most are the intake at the front and the side panel. And of course if you have water cooling and things like that.

I hope my videos are of any use to you. And any questions I'm happy to help in any way I can

here you have a guide

[tigre_est]

Great tips. Thanks everyone!

I found these BeQuiet ones with PWM control and "Rifle" bearings:
be quiet! Silent PSU & Cooling for your PC
Compared to the Silent Wings 2 without PWM control and with liquid bearings:
be quiet! Silent PSU & Cooling for your PC
What do you think of them? Can you advise me which of the 2 models is preferable to choose?
Best regards.

[Franziskaner]

a pwm controlled fan or a reo bus will always be better than one that runs at full speed all day long
prices?

@Franziskaner:

it will always be better to have a fan controlled by pwm or by a reo bus than one that spins all day long

14€ the pwm and 19€ the non pwm, but in different stores. The difference is in the bearings…

Look, the fans you've chosen are great for those who need to have them at a fixed speed without being able to regulate them, because they are very quiet, but they do generate a very low airflow to be honest.

However, the interesting thing, as they tell you, is to have the fans automatically regulated, so they always rotate at the necessary speed and yet if at any time more ventilation is needed, they always have an extra margin, so in an automatic way, you never go over temperature, nor do you hear the fans unless you really push them or turn your PC room into a sauna ;D
Let me give you an example; imagine a fan like the one you choose, but that rotates at 2000rpm and makes a bit more noise, if we had it reduced to 1500 it would make about the same noise as that one, but if it were automatic it could go up a bit more than 1500rpm if it's needed one day.

How is that done? Well, the motherboard, in addition to the cpu_fan connector, has others and in modern boards most of them can regulate the fan, you just have to look which connectors are adjustable, and if they do it by pwm or by voltage.
You can also use a manual regulator, placed on the front for example, but that's not practical or comfortable, it's just an easy solution to have each fan at the exact speed you want, but this way they won't go up when needed, nor will they go down when you're just reading this forum at three in the morning.

What motherboard did you have?

Great response Defaultuser.

The motherboard is an Asus P8Z77-V LE. Yes, it has 2 "CHA_FAN" sockets.

The doubt of whether to get the BeQuiet Shadow Wings PWM or not was that they go up 3 or 4 dbs at maximum compared to the Silent Wings, but I think I understand from what you're saying that the PWM control compensates, right?

Regards.

[tigre_est]

With your advice, in the end I am going to opt for a PWM. One of these 2:

Noctua.at - sound-optimised premium components "Designed in Austria"!

be quiet! Silent PSU & Cooling for your PC

¿Que os parece el Noctua frente al BQT?
