Hello, all my friends!
Today I want to discuss my PC gaming and I hope you give me some tips. I want to cool my PC Case with airflow but my PC case doesn't have in front and top.it's only have rear fan and side fan.
so my question is should I use side fan for exhaust or intake to cool down my PC? I used exhaust for side fan but when I'm playing a high graphics game it's hot on the side panel where is the fan located ("exhaust fan").
so is it correct?
Thanks!

Cases have intakes. Everywhere, including the pci slots in the rear. A case is generally full of holes.

If a case with a single exhaust is running @90° on the cpu, the addition of a single intake can drop that to @80° easily. 2x exhausts only drop it @2°C further, but 2x intakes with 2x exhausts will see the cpu @70°. Any further fans do either nothing or at most only drop cpu @2°C.

Most cases do not use dust filters on side fan vents. The gents are generally placed right around the gpu. Gpus vent heat out the side facing the panel. The addition of a side exhaust generally means that any gpu exhaust is vented directly out,not returned to the case, so don't impact any cpu cooler to any degree. Basically a side exhaust fan turns an axis...

It is my opinion that side fans should always be an intake. That way you have cool air blowing down on your cards. Exhaust can be handled by the rear fan and power supply to get the hot air out of there. If you can add a fan to the front, do it. A cheap fan might be loud, but cool air will help the computer run better and prolong the life of your components. In the ballpark of $9 to $12 isn't a bad investment to keep your PC healthy for longer.

Opinions vary on side fans. Personally for most situations exhaust is better, it removes gpu heat directly, lowering case temps directly, and most cases do not have any sort of filtration on side fans.

Best bet is purchase an intake fan. Use top and rear or side/rear as exhaust

I disagree immensely.

If its your sole option for intake it should be used an intake.

Personally I'd never buy a case with a side fan mount or ever use a wide fan.

As an exhaust though without any intakes ??

Your completely starving the system of fresh air.

Also with any stock downblower you're going to be creating a deadspot & making the cpu fan work much much harder.

Behold the age old cooling fans argument!

Everyone has an opinion. However, very few people have proof to back up any of it. In general, more fans are better than less fans. How you arrange them is system specific. As a result, no one has the best answer. It is all about delivering the maximum amount of cool air with the minimum amount of dust, unless you like cleaning your PC like I do, in which case, go for maximum cool air and just clean as necessary.

I have found that if you have a GPU with fans having the side fan as exhaust then there is no cool air for the GPU to use either i like to have rear as exhaust and front and side intake maybe if i have a water cooling radiator on top i will have that as intake too however i prefer to mount them at the front

Basically a side exhaust fan turns an axis gpu into a barrel fan reference design.

thank my friend for give me good tips and sorry for late reply.Should I decided to buy new case with having front fan? it is a good idea? when I play high graphics game , I always drop the graphics to normal which reduce the heat from GPU and I'm concerned about damage hardware in future!

for my opinion if I using side fan for intake air , I think it'll blow hot air (from GPU) to whole PC component and the rear fan just remove hot air out.it's higher risk for my opinion.

Gpu is usually good for sustainable temps of 70°C - 80°C. So unless you are exceeding that regularly, you will be ok.

For older amd use MSI Afterburner for gpu information. Can be used onscreen for real-time info.
For Intel cpu's use Realtemp, which also has a gpu temp.

If case airflow is a problem that's not readily fixable with additional fans or changes to fan curves, then a better case is always a good thing. Just make sure it fits your components, cpu cooler height, optical drive, gpu length and motherboard standard. A atx mid-tower will fit anything normally publicly available, but since it uses universal connections, may have issues with 3rd party OEM mobo's (HP, Lenovo, Sony etc) as they'll have proprietary connections, not universal.

If you do decide to change cases, knowing what the old motherboard is, is important.
