Crappy case airflow

[DBPenguins]

Hey guys. I've been having some temperature issues with my build from the start.

Specs: Ryzen 3700X with stock cooler, MSI X470 Gaming Plus MAX, RX 5700XT, Patriot Viper 3400MHz RAM, CoolerMaster Silencio 452 case.

Basically it seems like the airflow is abnormally terrible. With the original fans there was enough heat buildup in that touching the top of the case for longer that half a minute my starts to burn my fingers.

After that I threw the front fan out and installed 2 Noctua NF A14 fans in the front. Now these fans are supposed to move massive amounts of air and are quite loud at higher rpm. Even with both fans running at 1000RPM (which is already very loud), at 100% CPU and GPU load, the CPU sits above 90 degrees while throttling down to about 3.6GHz down from 4.05GHz on all cores. Opening the front panel on the case already improves the situation considerably, with most of the temperatures dropping by atleast 10 degrees along with the fans spinning more slowly and no more throttling. Opening the side panel causes another 10-15 degree temperature drop as well as fan speed reduction, and now the CPU runs at a cool 65 degrees with the fan speed down to 1700RPM (92 degrees 3000RPM + throttling initally).

 

Could it be that the Silencio case is really that terrible? I mean, it is supposed to be quiet case, but what is the use of the accoustic foam if the airflow is so shitty that the fans need to kick into overdrive to overcome that foam therefore being far louder than normal. Is the case really such hot garbage or does anyone have any ideas what I might be doing wrong? The front fans are intake, the rear is exhaust.

You already answered your question.

If the front panel is removed, the remperatures drop by 10°C, which means that there isn't enough airflow, even with high quality fans.

 

The case is simply terribly designed for such hardware.

 

In combination with the not so excellent stock cooler, the temperatures will of course rise even higher.

Yep from what I've seen on youtube that seems to be a common weakspot for quiet cases. I would recommend gamers nexus for case reviews, they do a great job and have good testing for thermals and noise.

Well, thanks for the info in that case.

With the side panel open the cooler seems to be doing wonders both temperature and noise wise, can't complain there.

Just can't wrap my head around the fact that a mid range cooler master case could be so terrible as to have ambient temperatures of 50-60 degrees inside the case under full load, even with high quality fans.

So can I safely assume that by changing the case and nothing else I can get everything running nice and cool without the fans going crazy?

Price doesn't change the product. There are plenty of good and bad case designs spanning the low to high end. 

 

Unless you have an aftermarket solution for exhaust as well, the stock case fans are too weak to provide good airflow for such components. 

Besides replacing the case, a more powerful rear exhaust fan would probably be the most effective solution. 

Where are you shopping / located? Budget?

At the moment not too interested in sinking more money into it (got more pressing things to worry about during this period) since under a typical load, the temperatures don't go out of control and the noise isn't too terrible, but I definitely will return to this topic at some point.

Thanks everyone for clearing this up, just wan't aware there could be such drastic differences between cases airflow wise.
