Do you need to upgrade your cpu cooler if you get a high end graphics card?

[BL3ND3RMAN]

This might be a stupid question, but I haven't found any answers for this, and I want to know if i can use the stock cpu cooler if i get a high end gpu?

Example: Cpu: Ryzen 5 2600   Gpu: RX 5700 XT

question about case airflow?

yes, if the gpu is constantly blowing hot air into the case

Short answer: no.

 

Edit, longer answer: a more powerful GPU will generate more heat into your case, causing interior case temperatures to rise. As a result, your CPU may throttle sooner or not boost as high as it would have before.

Not neccesarily about case airflow, but about the cpu cooler. I intend to use around 3 or 4 120mm fans.

The and long and short of it is, No you do not need to upgrade your cooler unless temps are high already.

if the gpu will make work harder the cpu because it will push more frames per second, no, but when cpu works harder the fan might do a sound you dont want to hear

 

so a heatsink with a bigger fan that can spin slowly and make less noise could be desirable

 

the xt you mention has a really noisy fan, you might not hear the cpu fan under load, ever, all depends on what games you play, airflow and heat generated

If you get a blower style cooler, then no, you don't really have to worry since most of the heat is going to be exhausted out.

 

If you get an open-air style cooler, then... still no. Such coolers will make the temperature inside the case rise a little and all getting a bigger CPU heat sink means is more surface area for that heat to be absorbed. If anything, I would argue look into making sure your case's airflow is sufficient so the air inside is replaced as efficiently as possible.
