Are case fans necessary?

So recently my pc was upgraded with a new mobo, CPU and RAMs, however, the case fan that was in the case was not added back in by the time I got my pc back? Should I put it back in or are case fans just not necessary? What would the reason be for not putting it back in? Just forgot?

 

My temps are: CPU goes up to 67 while playing, idles at ~55C, GPU is pretty much the same.

 

Gigabyte Aorus Elite motherboard, AMD 2700X CPU, 16GB Vengeance LPX RAM, AMD 580 8GB GPU. Windows 10 Pro. Switched from Gigabyte H81M-S2H mobo, i7-4790 locked CPU, and whatever those previous rams were. Honestly I have no idea.

Put them back. Need fans to push away warm air from the CPU and GPU and stuff.

 

Or else you can just keep the side panel open so warm air can escape by itself

Air flow is very important.

All fan case should be installed.

And you don't even have an exhaust fan......

55c idle is not normal for ryzen, it should be below 40c.

That indicates there's a hot pocket air circulating inside.

I suggest you add 1 inward fan and 2 exhaust fans, this will create a negative pressure inside the case, which is good to get rid of the hot air.

Positive pressure is preferable!

All intake, back exhaust!

Positive if the exhaust not adequate, will eventually create bottleneck of  hot pocket inside.

case fans are nesessary tbh [excuse me for bringing up a 20 year old system] but on my compaq presario its got a single case fan, you might think its not enough. but i performed a test where i shutoff the case fan and did some work with it, it was about a 5F difference believe it or not. case fans do help

Added the fan back in, idle temp sits at 45-50 with split second jumps to 60 when the clock speed goes up. Nothing else to do until I get my new case and case fans.

I once played for a couple of months without my exhaust. This was in a time when i wasn't paying particular attention to temperatures and such. turns out either i or the one who managed my pc ( it was returned for a checkup ) forgot to or accidently pulled out the power cord. If i remember this correct i had a lot of trouble with playing certain high end games but other then that it behaved .... about 6 months later i did got myself a new cpu because it started failing more and more. this could have been from the incident or old age or maybe even a combination.... just saying
