Duda fan for case

[Franziskaner]

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

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.

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

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?

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"!

¿Que os parece el Noctua frente al BQT?
