2 questions

[Dalli]

1) I got 2 air holes in my case (one on the back, one on top) and 1 fan (on the back)

    stock cpu cooler 

    2 gpu fans

    is that enough "air flow" in the case ? seeing that there is only one fan on the case

2) does the number of fans on the gpu really matter (1 or 2 or 3) if I'm not overclocking just basic gaming

 

thanks and sorry if these questions seem soooo dumb I'm a newbie in these stufs.

1) Not enough information to know. How are your temps? Use HWinfo to monitor temps while using the PC. Usually just 1 fan isn't great, though.

2) Yes.

Maybe I'm missing something, but I only see one question:

It mostly matters in terms of noise levels. More fans = quieter (once the fan curves are properly set up to account for the extra airflow).

A single fan in the case is the bare minimum, but personally I prefer at least having two (in in the front, one in the back) for a decent bit of airflow. A cheap and simple fan like the Arctic F12 should already do the trick.

 

EDIT: oh wait, misread. You asked amount of fans on the videocard. Well the above info still applies for case fans, but as for the videocard:

- more fans = quieter, but larger

I would get a 2 fan videocard at the least, but of course there are videocards with two large fans or three small fans which would be similar in noise level.

i dint get the first qn but the answer for the 2nd qn is it does matter a bit , keeping your gpu at good temps will lead to more lasting gpu , and it prevents the gpu from performance throttling , so i recommend getting a min 2 fan gpus and the perfect fans no. is 3 but as long as you dont go for anything above rtx 2060 , 2 fans will be more than enough to keep your gpu temps low

[Nathanpete]

You sure you don't have another fan mount (or as you call it, air hole) in the front? Single radial (as opposed to blower style) fans on a GPU aren't great, but the more fans the quieter. 

But as long as you clean out dust, and your fans are oriented properly (purshing air in and out the system smoothly, not fighting each other) you should be fine for basic gaming. 

[SupaKomputa]

The purpose is to give fresh air inside and get rid of hot air inside the box.

No hot air = cooler temps.

you can have 1 in and 1 out, 3 in / 1 out or the other way around.

It depends on the case design.

Huh, there is a reason why every RTX 2000 reference card has 2 fans, bc it is enough. Yes the 2080ti, and some 2080S's need more than two fans, but 3 is not the perfect number. 

[Dalli]

yeah sorry everyone I missed the first question, edited.

yep thats what i meant bro , 2 is enough for something below rtx 2060 to keep it at good temps , and btw the reference cards arent the most cool cards out there

the answer is it depends , most of the times nowadays you need atleast 3 fans to keep the pc cool

Ofc they aren't the most cool, but 2 is enough for everything or else Nvidia would have the same cooling issues as the reference 5700xt. TBH 2 fans is pretty much guaranteed to be enough for RTX 2070 and down.

The perfect number is 0.

True, if you got a heatsink so good that it doesn't need a fan mounted onto it then you are perfect.

1. Depends on the case and hardware involved. Big piece of plastic in front of the case will make 3 high speed fans worse than mesh with 2 slow fans. 3 fans in total is a good number for an mITX case, very few for EATX. You can cool R3 3100 + GTX 1650 Super with 3 case fans, but not 10900k + 2080Ti.

 

2. Depends on the card but more fans dont mean everything. Asus TUF 1660 and Dual 1660 are examples of more fans not better.

so u r telling me with 1 fan attatched to the CASE , and only a radiator is enough

  Thanks everyone for your help

I'm not currently near the case but I really doubt there is one on the front 
seeing its the only one should the case fan (RED) on the back blow air IN or OUT ? and cuz the cpu fan(GREEN) isnt facing any "air hole" would the airflow be fine ?

here is a fast paint drawing of the case

blow air IN or OUT

IIRC 1 fan blowing out should perform better than 1 fan blowing in.

 

But you'll have to manage the dust somehow.

I didn't say enough, I said that if someone made a heatsink so efficient that a single case fan could move the air away then that would be the perfect design. Bc it would be very very low noise and yet still be properly cooling. But that is mostly about CPU fans, you just can't do that on a GPU unless you want one of those frankenstein coolers that Linus has made a video or two on. 

Also I didn't say anything about a radiator. That would mean liquid cooling, we are talking about the perfect air cooler, but now we are incredibly off topic for the OP

Agree. Also, number of fans is only part of the story. Usually cards with 2 fans have a bigger fan diameter. What matters is the thickness of the cooler and its overall design (heatpipes for instance).

On Nvidia, I'll say no. Even the reference coolers this days do a decent job (with a noise hit) and the cards are way efficient.

Bigger coolers are designed for overclocking and low noise operation. The lower the temps, the higher PB will raise the clock aka "overclocking".

you need to be running your CPU and GPU to prevent them from throttling and which can result in decrease of performance

Yep, one fan pulling air out means that the air coming in will mostly come from the front where the other fan would normally be. One fan pushing air in would cause the air to become dirty (IDK the proper way to say it, but that is how they say it is motorsports) and there would be no natural routing for that hot air to come out the back.

I got a R5 3600 and 1660S , I got a pny (2 fans) and the shop I bought from suggested to change it to a gigabyte x3 gaming (cuz of a shipping issue) so you think I should keep the pny ?

so the case fan blows out and the air hole on top should be able to get enough air in , meanwhile the cpu and gpu fans will manage with the air inside

yeah but I dont think that I have fans on the front , I got the onl fan on the back and the cpu fan on its left and an air hole on top

Yup. And fresh air (and dust) will find its way into the case through any small holes too.

"manage" yes. "ideal"? No.

 

The better you cool that 1660S, the higher it will clock itself, and the better it will perform. The same goes for your 3600. The difference isn't huge, but its measurable. As long as you aren't thermal throttling, you should be okay. I'd recommend you monitor your system temps with HWINFO64. If your CPU or GPU are hitting the mid 80s or higher, you should consider getting another fan, or a better case.
