question Minecraft weird thermals

[zugfekete]

I just noticed how Minecraft beats the crap out of my system compared to every other game. After noticing my GPU fans are running faster than usual while playing vanilla Minecraft with shaders I started monitoring my thermals and TBP. I compared them to other more demanding games and it boggles my mind how Minecraft can be this power hungry. Not even the steel nomad benchmark in 3DMark had results like Minecraft. Here are som results:

 

Ambient room temp: 31C

 

all data below are what HWinfo logged and avaraged:

 

Minecraft 16chunk render distance, Complementary Unbound shader at the "max" preset:

GPU  ~66C

GPU Hotspot  ~90C

CPU ~80C

GPU TBP ~ 270W

 

Cyberpunk 2077 Maxed out graphics except ray tracing with FSR3 (in intense combat):

GPU ~ 58C

GPU hotspot ~75C

CPU ~73C

GPU TBP ~ 270W

 

3DMark Steel nomad:

GPU ~60C

GPU Hotspot ~81C

CPU ~70C

GPU TBP ~350W

I'm just curious what your opinion on this is and I am aware that all of those temps are in safe ranges but I'm still intrigued why this happens. If someone has an explanation I'm happy to listen.

My setup:
Ryzen 7 5700X

Gigabyte RX 7700XT 12GB OC

ROG Strix Gaming II B450-F

32GB DDR4 RAM @3200MHz

Coleer Master Hyper 212

EVGA G+ 650W 80+GOLD
Deepcool Matrexx 50 Glass front (yes I know glass front is herrendous for airflow but it was a gift from a friend, I wouldn't have bought it myself)

That's really weird, especially because the 3Dmark uses 350W instead of 270W. What is your GPU % usage in Task Manager or any other software while doing the three games/benchmarks you mentioned? What is the clock speed?

Do you have V-Sync or VRR(Freesync) enabled? If you have the games set to unlimited frame rates, especially on games that are easier to run they'll push out the max frame rates they can potentially pushing the GPU/CPU harder then if you were playing at a capped framerate. If you were to cap Minecraft's framerate to say 120fps or whatever your monitor refresh rate is it should lower your temperatures while playing.

I had to rerun the "tests" since I didnt log usage in HWInfo.
Minecraft:
GPU clock ~2700MHz w/ ~99% usage

CPU clock ~4,32GHz w/ ~27% usage

 

Cyberpunk 2077:

GPU clock ~2700MHz w/ ~90% usage

CPU clock ~4,6GHz w/ ~54% usage

 

3DMark steel nomad:

GPU clock ~2600MHz often dipped to 2500MHz which didnt happen with the games w/ 100% usage

CPU Clock stable 4,65GHz all the way thru w/ ~10% usage

(Usage %-s are what the application itself used not overall)

I tried all three options, I tried 144Hz V-sync ingame, freesync and unlocked FPS, all led to the same conclusion. Which is especially weird since Cyberpunk 2077 and RDR2 both ran at a higher FPS count than Minecraft with uncapped FPS which was an unstable 250FPS with dips to 80 and 120.

Edit: the thermal tests I listed were made with unlimited fps on both cyberpunk and minecraft.

 

Edit 2: Nevermind sorry, the ingame FPS limit kinda fixed it, for some reason minecraft didnt actually cap my FPS when I set it at 140FPS and I didnt notice because it was very unstable. Now its 138FPS but the thermals are still higher than other games, its not 90C now but on avarage its still higher than 3DMark's benchmark and Cyberpunk 2077
