Laptop heating issues.

[lisianthus]

well, i'm on vacation and can't use my real PC, so naturally i try to play something i actually can on this laptop (HP Envy M6 1105dx). but after a little gaming (even with a decent laptop cooler stand with the fan blowing RIGHT on the intake for the fan in a 68*F room i still get a huge sudden spike up to 140*C

i was running prime95 and furmark burn in and it held a constant 78 - 80*C then suddenly jumped to 100*C at that point it hit thermal shutdown, but it kept my numbers up so i print screened it.

i ruled out the fan not working or stopping, it was holding a fairly constant temp for almost 15 minutes then suddenly it just shot up in about 2 seconds.

I would say that the thermal paste on your heatsink might need replacing... otherwise try to see if other people with the same or similar laptops are having this issue, as it may be something that is common, and has an easy fix. Also is it in warranty? If so try RMA'ing it.

i was thinking thermal paste or the heatsink needs cleaning, but why would it spike 20*C after being steady for 15 minutes under full load (prime and furmark)

i think you should get an external cooler, depending upon how old the processor is it can get pretty heated up, you can change the heatspreads or the thermal paste (both) , increase the fan rpm's if possible , on the otherhand doing the intensive benchmark on laptops isn't advisable, we know how laptops can match up against desktops , so this was a no surprise , it's made just to get tasks done not hold off an army of 3D monsters,

Well, it's HP (dat thermals...)

And that spike could be a reading error

well that possible "reading error" is shutting my laptop down, fairly annoying.

i was just trying to get to the bottom of why its shutting down while playing Final Fantasy XIV. the stress test was just to see whats going on. when i get home im going to replace the thermal grease with the little bit of arctic silver 5 i have left.

I have no idea what you mean by external cooler, unless you mean the laptop cooler that mine is currently sitting on

[lisianthus]

Well, It'd shutdown at 105 ºC...

Also be careful with that thermal paste, it's conductive, laptops don't have IHS, so you're applying it directly in the die...

i have replaced thermal compount on a few laptop CPU's, i'm not that new to it.

[lisianthus]

ok then :lol:

Thanks for the warning anyways, would have been useful had I not known.

Everybody says new thermal paste, which is important, but see if you can get every piece of dust out of the heatsink and intakes. Everytime I do this I lose about 10 degrees C. It can get really clogged in there. The other thing I can think of is that there is damage to your CPU. Furmark is designed to push CPUs past their thermal limit and can easily destroy your chip. I hope that's not the case!

Well i actually decided to take this laptop apart for the first time... (I bought it on ebay used for $200) and this is what i found

 

umm WAY to much thermal compound... WTF it was fairly dried up as well, felt like clay.

[Prokart2000]

well there is your problem its dry

[lisianthus]

wtf did the last owner use? I have never seen arctic silver 5 dry up like that in a year or so of use.

 

either way it was WAY to much, it looked like they just used the entire tube of thermal compound.

Yikes! It might be the extra thermal paste is causing shorts and tripping the sensor for the huge spikes.

 

Clean that shiz ASAP and reapply thermal compound. Keep me updated I'm curious.

well i did clean it, and since i'm in the middle of no where right now, i have to wait a little while to get thermal paste. i did however use a little bit of the gunk that was all over the place, my temps are down to 78-80 under the same test and no longer spike. when i get home i will be applying arctic silver 5.

And I went out to buy some AS5, put it on, boom 70C max and it actually maintains 2.7GHz rather than throttling down to 1.4GHz when it hits 80C.

I also happened to see an M-Sata port hidden away in the chassis, only way to see it is to take keyboard and top cover off. (so the Hp Envy M6-1106DX has an M-sata slot)

Make sure that  your power mode is on balanced, and not on 'High Performance' This worked for me and gave me much better thermals and the same performance

The problem has already been solved, it was a thermal paste issue, I have my laptop my own custom power profile.
