Steam deck LCD overheating at 75C

[Pushyrummble]

I’ve been experiencing an ongoing issue where, while playing many of my games, either the GPU or CPU reaches around 75°C causing thermal throttling and makes my FPS tank. From what I’ve seen, others report temperatures reaching 85°C and have no problems, and some sources even mention that devices can operate up to 100°C. I’m wondering if it's normal for my Steam Deck to experience this once it reaches 75°C?

definitely not normal.

Its not supposed to throttle until it hits 95C

What are your power settings? It might be power throttling instead of thermal throttling

[Gurtiev]

As Drak3 said, your device is probably experiencing throttling issues due to some other factor. Maybe the SOC is at a good temperature, but the power phases (MOSFETs, VRMs, etc.) are bad and losing efficiency as the temperature increases.
I recommend sending the device in for RMA, and if it is out of warranty, find a store that deals with laptops and GPUs. They will probably have the tools and knowledge to fix the problem.

Before that you can try to factory reset the device to see if the problem goes away.

This is probably the case, I have factory reset it and it continues to do this. Forgot to mention it doesn't do this while connected to an outlet only when I'm relying on the battery itself.

Probably the battery is not providing enough power to keep the performance then it throttles due to power limitations instead of temperature limitations.

In this case it probably is the battery, or the bms.
Try to look the battery health status clicking in the icon close to the clock in the desktop mode.

Go to desktop mode and check the battery life or try to replace the battery, it's not hard to do only the glue being a little too strong, i I've changed mine because the battery swelled.

The battery health I have currently is 84% not bad, but idk if it's enough to affect something.

The power draw can be bigger than the battery can deliver, that's why I recommended you to check

I checked the battery health it's at 84%, you think it's still good or would a better battery be recommended?

[Pender666 | Marcus Vinícius]

My battery swelled with 94% of health but I chose to replace it for safety reasons. You should try to find why there are so much battery drain. What are you doing exactly to drain your battery. I noticed that CPU heavy games drain the battery really fast instead of GPU heavy games. I measured up to 12w of power drain only by the CPU.

No it's not normal for your deck to throttle at 75C (unless it's actually hitting 95-105 inside and you are looking at the wrong temperature). The battery has nothing to do with this.

It was the default 500GB LCD Steam Deck from the initial pre-order batch. When I enabled the performance overlay, I would see that the GPU or CPU temperature would reach 75°C. Under load, both components would intermittently throttle to around 10% performance, causing the game to become temporarily unplayable. Once the temperatures dropped, it would go back to playing normally only for the cycle to repeat.

If there's a different setting I can check to see the temperatures of other parts do let me know. So far, I never seen my GPU or CPU temperature ever go above 75°C.
