CPU Overheating Temps for x220

Hello,

I know theres a few threads going on regarding tempatures of the GPU/ CPU and what not, but I'm still not able to find my answer.

Here's a generally what I am trying to figure out:


1.) I am using Real Temp 3.67. At what temperature am I slowly killing my laptop? I am hoping to have this laptop last me 4+ years, so I'm trying to figure out what games I should and should not play on this.

2.) I've seen MobileTechReview play Left for Dead 2 for a review video. It runs amazing on the laptop, even in low settings. However the temp of the CPU shot up to 93'C max. Is that dangerously high?

If someone could provide me with some general answers, I'd be grateful.


Thanks,

 

What temperatures are you getting? I've seen my T420s CPU get into the 90's C. The CPU will start temporarily throttling at around 95C as thermal protection. I've seen that happen on a few occasions when I've been using HWiNFO32 to monitor CPU speed but maybe it happens more often.

If you are worried about sustained high temperatures then you could customise your power profile to used balanced, not turbo or maximum performance. This will limit the CPU to the maximum non-turbo speed and should take at least 10C off the temperature. I haven't seen a way for users to control the amount of turbo boost. I suspect that the assumption is that the system knows best how to balance temperature and performance.

At any temperature, your CPU is degrading. The hotter it is, the faster it degrades. There isn't really a "max safe temp" other than the rated Intel temp of 100*C (the temperature at which the CPU starts to throttle). The only thing you can really do is try to keep it as low as possible.

Read this article here: AnandTech - Intel's 45nm Dual-Core E8500: The Best Just Got Better

 

Keep it under 100c. The cpu should easily last a long time.

 

I would be more worried abut high temp killing the battery longevity since heat and batteries don't go well. The reason batteries dies is the heat kills the cells I read somewhere, sometime.

 

Core i series processors run hotter than the previous generation Core 2 Duo's. 100C is the max I would say for a standard notebook with a Core i series processor (like a T420, T520), and only for short periods. For ultrathin notebooks, you probably don't want to go above 90C for prolonged periods for obvious reasons, their cooling is way inferior to standard notebooks.

 

90s? Dang. The highest my i5 in the T420 went is mid 80s on max CPU stress in prime95. Real world use in gaming/photoshop never goes above mid 70s.

 

That's one of the benefits of the T420s - a thinner profile with smaller cooling system.

THank you everyone for responding to this thread! Love how everyone here is so helpful ^.^

@JohnRatsey my idle temp is between 40-50C

 

That looks good, but what about your full load temperatures?

John

 

Sorry not too sure what that is, I'm a bit new at this kind of thing. Is full load = the highest it's been? If so, it was during L4D and it was at 93C

 

When I use intelburntest, my highest temp easily goes to 97c.

I've even changed the thermal paste! At first I thought it helped with a few degree difference, but over the last few weeks of testing, the changed thermal paste seems to have made little, to no difference.

 

What is your ambient room temperature?

 

What paste did you use? I too recently replaced the stock TIM with AS5 and my temps have been dropped quite significantly. About 88C under the full load (Prime95, CPU at 100%), 38-40C is my idle temp and something like 50-53C when it's under a normal / regular work load.

 

I used Shin Etsu g751. Do you have the i5 or i7?

 

I have i7-720QM in my laptop.

 

Hmmm, do you have the right forum? the x220 doesn't have that processor.
