Laptop temps too high?

[Nick R]

So now that I sorted out that thing yesterday, I thought I would run linpack (Intel Burn test) to check what the maximum CPU temps I'm getting are. Well, I got this. It's a AMD Phenom II N660 (Dual Core, 3Ghz) seems a little on the alarmingly high side for these chips. If my 2500k was hitting that, I'd be less concerned because those have a much higher tjmax temp. It never gets this hot under normal use, but that seems a little alarming either way.

Most laptops or computers in general for that matter with all the power they have, rarely need to sit at 100% CPU load. I wouldn't worry about those temps. Especially if the laptop is still stable. Doing what most laptops these days do, you will never hit 100% sustained load on both cores for any period of time. So in my opinion its not worth worrying about.

What is the idle temperature?

There's thermal protection. If it's too hot, the proc will downclock or even halt. I wouldn't worry about it.

If you are really THAT nervous, you could always rip it open and put on a better thermal grease...sometimes they skimp or overdo it from the factory.

ITB on a laptop? Brave man.

Simple solution...don't run ITB! Unless you are testing stability with an overclock, there is absolutely no reason to run ITB on a laptop, or even a desktop. It doesn't reflect real world usage, even in the most extreme situations. Whatever temperatures you achieve with it are not likely to be replicated in day to day usage, so I wouldn't worry to much about the temps you posted above.

Actually I did yesterday. I had it torn apart to replace the wireless card and to fix the touch buttons above the keyboard (=P). using AS5 I redid both the CPU and the NB.


Not really nervous, but I though the cooling system would keep it at a lower temp than that.Also lol 18GFLOPS. My 4.3Ghz 2500k is pushing 114GFLOPS.

IBT is brutal it routinely made my i5 hit 125w in testing and its 95w rated..

the temps were also about 10-15C higher than prime95


so.. I wouldnt worry about it.

you also ran it on the maximum setting.. thats crushing.

Laptops really aren't 100% duty cycle items. To save on cost, and to reduce noise, your average laptop is designed to cope with only short bursts of high load. And unlike a desktop, the heat isn't localized, but instead bleeds over to more sensitive components. Even the power bricks aren't 100% duty cycle items.

I could run IBT on my desktop 24/7, but my desktop is huge, has an advanced cooling system, and every component is more or less isolated from each other. Laptops don't have this luxury, and its part of the reason people still fork out a lot of money for dedicated laptop coolers!

Pretty much what pzev says. I loaded down my T500 really crazy once. Two threads P95 torture test and FurMark on the Radeon graphics. The temp kept climbing until the CPU hit about 95C and it shut itself off.
And that is how I burned out the chinese power brick it came with.

If the laptop (any computer, really) can pass a round of IntelBurnTest with accurate results and without shutting itself down, I wouldn't worry about it. I ran IBT on a desktop that was overheating and the cores reached >100C and the temperature values actually wrapped around and started disappearing or displaying ridiculous values like -26C. It wasn't crashing or shutting itself off, but I shut it down shortly after seeing the crazy temperatures.
