Question about Intel HyperThreading

[LShun]

Hello, can I ask some questions here?

The laptop I have, especially when playing DoTA 2 on Ultra ( CS:GO and others doesn't generate too much heat ), would cross 72 degrees celcius but won't down-clock itself. I wonder if disabling HyperThreading will help to alleviate this issue? Would it do?

2. Can I know is there alternatives other than going into the BIOS and turning it off.

3. Will it void my warranty?

Thank you.

72 degrees is not at all unusual for a CPU, let alone a laptop CPU working hard. You're fine until you get into the 80s and approach the 90s. Unless something is seriously wrong the CPU should protect itself from overheating. Most laptops and portables now are actually thermally constrained, in other words the device quickly gets to peak temperatures and then bounces around between lowering clocks & voltages to keep temperatures under control.

What's the problem you're trying to solve? Are you worries 72 is too hot?

Yes, I worry that 72 is too hot and will affect other components such as the transistors. While playing Hitman Absolution it gets to 78 degrees. Wil other components get haywire or burned overtime such as the HDD? Thanks

The surface is also made from brushed aluminium, which, conducts heat. So my hand feel very uncomfortable when placing on the surface.

As I understand it, hyperthreading helps it run faster and cooler. What hyperthreading does is when a part of a core isn't running, it can pick up what another core is supposed to be doing, saving strain on the other core. It also really helps in games where the CPU is made to do most of the work. Lots of modern games, like Dota 2, use the hyperthreaded cores. Turn off hyperthreading, and you might not be able to play on Ultra. If you're worried about it getting too hot on your lap, then just tone the graphics when it's on your lap, or get a cooling pad.

There's no way that I can tell to disable hyperthreading beyond going into BIOS, but it's not hard to do. Just hit the right key at the splash screen at boot (usually one of the function keys).

Disabling it won't void your warranty--especially since the reason you want to disable is to make it last longer. Overclocking it (which would make it get hotter, and go bad sooner) usually does though.

Weboh, thank you for your explanation and help .

rhysian, I finally know the reason of why I am so worried. When I touched the surface it is extremely hot when playing Hitman: Absolution. And so I picked up another two thermal sensing tool, Core Temp and HWMonitor. And it hits 90 degree celcius.

But now I know that hyperthreading helps, I won't disable it. Thank you for the helps given.

Just to confirm you, disabling HT wont do any good.

I see thanks. But can I ask one more question?

My laptop seems to reach 95 degree celcius as stated on CoreTemp. Its still under warranty, what should i do?

What do you think? Contact the manufacturer. They'll probably have you send it in, if that temperature is bad for the computer. If it won't damage the computer to be that hot and they won't fix it, you can buy a cooling rack to make it cooler on your lap.

I see, thank you for your help! Upvoted you since the best answer is already picked
