How do I change the Temp. Limit of my CPU?

[dalpsanli7474]

My laptop's manufacturer set the temp.limit of my CPU which is a i5 7200U to 95c. But Intel says that the temperature limit is at 100c.

How do I change the temperature limit?

Thanks for all answers.

You don't.

Manufacturer's can implement the chips however they wish. Typically, they adhere to Intel spec.... but there's no requirement to do so.

Depending on the cooling solution implemented, manufacturer's may apply a further restriction, enforcing throttling at a lower limit.


Theoretically, firmware flashing could allow you to run at "stock" spec.... but if the temp limit is lowered, there's very likely a justifiable reason for doing so.

It can be done in BIOS, which can be accessed by mashing F2 or backspace when your pc is turning on. Your processor should not be getting nowhere near as hot as 95 degress anyway. Good luck

Why do you want to?

It depends on the implementation, but typically, a CPU throttle temp is not dictated in the BIOS - at least not at a level that you can change easily.

A lot of mobile implementations, depending on the laptop, get really hot. 95'C wouldn't be unheard of in some stressful situations. Not ideal, but you're bound by the cooling ability of any given laptop. The thinner you go, the less cooling ability there is.

Clearly the manufacturer of this laptop isn't confident that a CPU hitting it's rated spec (105'C) is ever going to cool down sufficiently with the cooling method used, even with throttling -- which is quite disappointing.

Just as an FYI:
F2 is not too common for BIOS access these days, outside of Acer IIRC (and I don't recall if backspace ever was), you'd be more likely to see "Del" or maybe F12/F8, depending on the laptop.

You don't.
Intel may list the theoretical temp limit at 100C, in absolute perfect conditions.
The laptop manufacturer, however, has other issues to consider. Case design, other components inside, etc, etc.

My bad, thanks for telling me. I've only used slightly older hardware (Haswell chips, fx processors), so it makes sense , why Im slightly behind newer motherboard implementations (such as new BIOS access commands). BIOS of ASRock 970 Extreme 3 r2.0 actually does allow for change of temperature, at which cpu starts to throttle but ofcourse I can't be certain, when it comes to other boards.

There's much more granular control on desktop components, as you have greater control over cooling etc.
You can disable warnings, and change the "shutdown" temp trigger on some boards.

This CPU though, specifically, is in a laptop -- much less control there.
