Do i really need case fans?

[SomeonesDad]

My pc currently only have one fan in the case, its the stock one from phanteks, my cpu is being cooled by the stock cooler as well. My cpu runs at a stable 69 degrees (nice) and my gpu is hovering around the 70s, but if i were to use it long enough, it can reach the 85 degrees but it rarely does. My case have 3 140mm fan slots empty. But there is one small problem though, my case gets really hot if i used it for a long period of time doing heavy tasks. 

So my questions are:

1. Will case fans solve the hot case issue

2. If it will, will i need good quality ones

3. Can you give me a suggestion on a fan that cost around 10$/pcs (I prefer not having rgb)

Do you need case fans? No. Will they improve your temps? Very probably. Just remember, intakes are filtered

This is a pack of 5 for 25$. They aren't gonna be nice, but they'll shift air

the p300 only has 1 fan for exhaust, adding 1 extra fan for intake should help getting more air inside the case.

Probably yes, but a hot casing doesn't matter as long as your components don't run hot

No you don't, unless you want them to be quiet or run at low rpm, which noctua fans do very well

 

To find out if your airflow is causing heating issue, open up your side panel

If temps on CPU and GPU drop more than 5-ish, then it's insufficient airflow, around 5c ish drop is normal

Just get 2 more Arctic P12 PWM's and put them in front. This will solve any issue you'll have in terms of temps. Depending on where you are you can get them between 5$ and 10$ each. They're not much, but they get the job done. If you want something better the Arctic Bionix F120 are a very good choice, as they move more air as a case fan.

You linked the arctic f8's those are 80mm fans what op will probably need is the f12's which are the 120mm ones. They are actually pretty darn nice fans for the little they cost.

Thank you for all the responds guys

Too bad you cant buy the p300a front panel separately like with p400a.

 

You could try what nzxt did with their poor airflow case (h510) and try roof rear exhaust only. It should draw fresh air for gpu from the empty pcie-slots.
