Lately got into upgrading my pc a bit and I want to install an overhead fan in my compter case.
Said fan is Antec Prism Cooling Matrix.
Dont know the model of the case so adding a pic as follows:
My PC Case

How do one do such thing?

EDIT
Looking for advices to improve general performance (temps, airflow and etc)
So any opinion is a help :)

My guess it that you remove the mesh on the top and then screw on the fan where you want it.

Dont know why you would want a fan on the top. Front and back should be fine for airflow.

Actually got a lot of dust build up even after a short period of time.. figured it might be a good solution for this.
With lowering the temps ofcourse

Most cases only have 1 rear exhaust fan mount, so if you have multiple intake fans, it's good to pair them with exhaust fans for matched CFM ratings, otherwise you're going to have airflow imbalance that'll just bounce the heat around in your case and won't cool as effectively as it should, while also increasing the accumulation of dust inside the case.

No problem, also keep in mind, hitting a perfectly balanced pressure in your case is damn hard to do, and although you want to match up the airflow pressure between intake and exhaust the best you can, you'll want to avoid causing negative pressure. Basically, if your exhaust are pushing out more air than your intake are pulling in, it'll cause negative pressure, and air will start being pulled in through holes/openings around your case, which is even worse for dust management. So yah, try and get 2 or 3 intake and exhaust fans of matching RPM and CFM ratings if that info is available, and if you need to test to ensure you don't have negative air pressure, maybe get some incense burners, light em, hold near open holes to see if smoke gets pulled in (back of case is prob best indicator). If smoke does get pulled in, maybe try ramping down the RPM on one of the exhaust fans if possible.

A really helpful tip, will do!

Your case is an Antec GX330, and it supports up to 3 fans on the top of the case. You need to remove the plastic top panel (be careful since there's a lot of cables running around there) and you will see the holes for fan screws/clips. The double fan you linked to can be used if you want to, it has the same dimensions as 2 separate 120mm fans so it will fit.

This website has a small section on installing fans on the top of the case, scroll to about half way down the page: https://tech4gamers.com/antec-gx-330-window-black-high-blue-edition-review/

Bear in mind that unless you already have a good amount of air flowing into the case through the front panel, installing 2 fans on the top as outtakes isn't going to improve your temperatures much. A better solution would be to buy 2 separate fans, put one in the front of the case, and the other in the top nearest to the back.

I recall reading a study that showed having a lower internal air pressure in a computer case was better for cooling. It may even be linked in these forums somewhere. :)

That would be interesting to read. I always heard that having an optimal airflow (from front to back) is the best setup. Air is drawn in through the front, goes through any heatsinks and components, then leaves. Without a sufficient intake air could be drawn from any gaps and holes in the case, without necessarily going through any heatsinks. A positive pressure is also slightly beneficial since air would be drawn into the case through dust filters. With a negative pressure, the air that gets inside through gaps and holes could increase dust accumulation.

I did my own research a few years ago when planning my own fans and both had pros and cons. A positive pressure means more air through fans and filters meaning less dust but apparently lower pressure creates lower temperatures inside the case. So take your pick?

Actually this is a solution I thought about to reduce temptures but also reduce the dust build up.
I admit that I dont have a lot of knowledge in PC hardware and I do look to get some insight about that area.
(If you have the time and will, I would really like to consult on which solution is best in my case.)
Anyway though, thank you very much for your input!
If you recommend that, Ill go with buying 2 separate fans and put them in the same areas you were suggesting.

Dust will always build up, why a 3-6 month clean up is never bad.
Argh the noise the fans can make wants it piles up.

As other people mentioned, there are different ways of mounting your fans and they all have valid reasons behind them.

I would personally want a balanced setup, with an equal number of intakes and outtakes (eg. 2 at front, 2 at back/top), but there isn't anything inherently wrong with putting more outtakes on the top like you wanted in the first place.

Bear in mind that the double-fan design you want has RGB lights in it, but you won't really be able to see them because the fans will be mounted inside the top panel, not right above the motherboard.

Why do you want to reduce your temperatures in the first place, by the way? A better CPU cooler is going to give you better results than more case fans, unless the one you have is already very good or your airflow right now is very bad.

Simple curiosity, what kind of CPU cooling system do you use ? Fan or liquid ?

Fan, bought this system premade

Thanks. There was a promo liquid cooler given with the mobo I bought 1 or 2 years ago, so I've a different setup.

No problem, actually upgrading the stock CPU fan with an Arctic freezer 7 x as well

before you add some fancy top fans you should populate all fan mounts in the front (air in) and back (air out) if you haven't already.

Due to that I think what I do is mount the double fans I wanted in the front and take the one I already have in the front and move it to the top back of my pc.

that sounds reasonable. i would test that out and if you want you can always add another fan later. but then you only need one extra fan in the top (air out) over the cpu cooler. using three fans in the top will only create chaos with the airflow.
usually the top part of the case is intended to mount the radiator of an all-in-one watercooler. it's not really intended to put only fans there.

also buy good fans and not some cheap shitty ones.
4 pin pwm fans can go down to 20% fan speed or even less. if your motherboard has enough headers to connect them!
old school 3 pin fans can only go down to 50% fan speed and usually that's too fast / too loud for case fans.

plus you can always use good fans in your next case / computer as well.

I would be happy if you would send me a link for a "good fan" as an example because i dont really see the difference with them..

of course it depends on your budget but a good fan will last you many, many years and like i said you can use them even in your next computer.

in spring 2017 i built a new computer for my sister in a corsair case. that case came with three corsair fans already installed. after less than one year all three fans started to make rattling noises and we had to toss them in the trash.
so in spring 2018 we replaced all three fans with noctua NF-P14s redux-1200 PWM and they have been running perfectly ever since.
they also have 120mm fans if you don't have room for 140mm: https://noctua.at/en/products/fan/redux

you cannot go wrong with noctua stuff. they are not cheap but they are 100% worth the money.

My current ones hold up pretty nicely, in any case I'll need new ones ill be sure to purchase the brand you recomended :)

first front, then top, then back.

Top will throw hot air going up from CPU/GPU. Almost all cases got place for 1x fan on back, it cant take much hot air out, 3x120/2x140 on top is good, cause hot air is going UP
