CPU Temperature above 85*C

I am running a Core 2 Duo T5600 1.83GHz, and I have noticed that my CPU temps start to spike upwards to about 86-88*C when I am just converting video for my Zen Vision M.

I have been using Notebook Hardware Control to monitor internal temps and the CPU load. The load often hovers around 98-100% just for converting video. Is this normal? I'm afraid this will cause damage to my machine and we've not even hit the hot months yet.

 

From what I've read that's normal, converting video/music is a really cpu intensive task so your cpu should be close to 100% load.

I think up to 90 C is acceptable but I'm not 100% sure on that.

 

CPU load normally spikes when you are doing any kind of video processing. My turion's temperature sky rockets when I am doing any kind of video editing in windows movie maker, not to mention the CPU usage spikes on both cores... Of course I keep my temps down as much as possible by undervolting as low as possible at max load.

 

Check out the cooling guide for some tips to lower that temperature. It seems a little high to me.

Are you sure HardWare Control knows what it's talking about? HC on my laptop says 45+ degrees coming out of Hibernate. Even at 20 degree nominal room temperature.

 

The system will shut down if it gets too hot. So if that doesn't happen, it doesn't get too hot. (Or in other words, you don't have to worry about frying your CPU).

Core 2 CPU's tend to get really hot in some notebooks, and up to 85 or so probably is to be expected.

But if you can lower the temp, that might be a good idea still

 

I think you need to check your cooling system for dust and other problems as 86-88*C is very high even at 100% cpu usage.

mabe re-do the thermal paste on your cpu, use some AS5

my cpu runs quite hot but it`s only ever got to 69-75C max

Look into undervolting. These CPUs normally undervolt quite well (I've got my T5600 set to 1.0V at maximum speed) and power (= heat) is proportional to the square of the voltage. There is a collection of advice in this undervolting thread. When time permits it will be turned into a coherent guide.

85 degrees is pretty toasty. You definitely don't want your processor being that hot. Try undervolting or cleaning out the fans on the laptop. If all else fails, invest in a laptop cooler. There are some great ones out there made by companies like Targus.

Of course, it's also completely possible your notebook hardware monitor is going haywire and reporting completely incorrect numbers. Notebook Hardware Control registers the battery at 100% on my laptop even after I've been using it for an hour. These programs aren't foolproof.

 

More than a few Core 2 notebooks have been designed to operate in that temperature range under load. That said, it is certainly in the high end of what I'd feel comfortable with, but it's still not hazardous.

(Bu as you say, it isn't uncommon for the temperature monitor to be off. Sometimes it can be off by as much as 5-10 degrees)

 

Before I undervolted, my T7200 would hit 85C after a couple hours of CS:S.

Now, I rarely hit 75C.

 

There is this WONDERFUL program called i8kfangui31 It lets you set a temperature that you want you fan to kick in at high speed. I have it so mine starts at 35 degrees, and doesnt stop till 20. Just to be safe.

 

Yeah and not all notebooks are supported by it, so that's not really an option for everyone, unlike undervolting, or cooling pads, which work for all laptops.

 

Wow, thanks for the great response. I'll look at undervolting, as I know that Hardware Control offers that as an option.

As for the Artic5, I had Ken assemble all of that for me, so I would need to talk to him to see exactly what/if it would void my warranty.

Thanks again.

 

85 C....? am i that old.....? carter tried to make us use metric.....com'on now that'd be like 185 f.....now that's hot....best pak dry ice 'round that bad boy.......
