Studio XPS 16 laptop CPU heating

Hi,

My CPU runs constantly on 68-72 Celsius ( All 4 cores )
The laptop itself gets very hot.
Is this normal ?

Thanks
Eddie

 

What CPU is that?

 

Its the i7-820qm

 

That sounds quite high but not dangerous.
What software are you using to record temps and have you checked for dust build up on the fan?

 

I use CoreTemp to get the temperature.
The machine is 2 months old and already motherboard was replaced after what I suspect was a thermal shutdown during gaming.
btw, The temperatures I specified are at idle time.
How do i check for dust buildup ?

 

2 months, wow!
You can check by just looking through where the fan is, but if I'm honest at 2 months old I suspect something else more serious (sorry!) either that or there wasn't enough thermal paste put on it when it had a new board?

I would be tempted to ring the back and telling them it's still happening.

Unfortunately for some on here it looks like they have to go through a few books before they get a good one that works.
Which, is absolutely shocking.

Balls in your court mister...

 

About 80-85 is what you should get while the system is stressed. What are your temps when the system is stressed. If they're 90+ then your thermal pads are likely not applied properly. TJMax for the Core i7s and most Intel CPUs these days is 100 deg C. Anything below 85 is absolutely safe for you. Have been using the SXPS 1645 for 6 months with these temps and no problems whatsoever.

It will heat up on the outside though. The magnesium alloy chassis is there for strength and better heat dissipation. That is one thing you're gonna have to live with.

 

well... if a laptop heat up to the degree you cannot use comfortably than there is a problem. I use it though with an external monitor most of the time.
Intel documentation specify 43-67 Celsius as normal range.

I will definitely try to return it.
Thanks for your advise, guys

 

No problem. I wish you the best of luck.

Keep us updated

 

What are you doing? If youre gaming or running the rig at full tilt then those temps are actually not bad for an 820QM.

 

some good info for you.

Under load (gaming for 10mins) my CPU gets to about 85 C and then starts to throttle (due to power and NOT temp, I'm assuming), I wonder what it would get to under load for like an hour? Of course the load temp is about 5 degrees cooler when using an external monitor. Also using a 6-cell battery but starting to look at getting a 9-cell for better cooling. My idle temps are in and around the 60 C range and can go anywhere from 65-75 C when doing regular tasks or hd video playback. I've just come to accept the heat this thing gives off on the bottom, if the throttling problem was fixed and I could game at my leisure I truly would rejoice.

 

@wetcardboard

Are you monitoring your GPU temps? If your GPU temps hit around 93 deg C and then your system is throttling, it is NOT power based throttling - just a BIOS mechanism to prevent damage to the system board. However, your GPUs shouldn't get that hot under any circumstances anyway, unless your ambient temperature is high (above 27 deg C). If you GPUs are still getting hotter than that, then your thermal pads are probably not applied properly, and you can have Dell replace them.

As I can see from your idle temps, they are about 10 deg higher than what they should be. I see about 51-52 deg C idle on CPUs even in a warm room, so I bet your thermal pads are not applied properly, or your heatsink is faulty. Get Dell on it!

 

I've never seen my GPU go above 85 C or CPU above 84 C, but I have never been able to stress my system for more than about 10mins before throttling kicks in. Remember I have the 6-cell battery so airflow is not optimal and my idle temps (PC on but not doing anything are around 55 C, with light load up to 65 C and watching HD videos in the 70-75 C range. Right now I've got the unit on my lap doing web browsing and e-mailing, making sure my left leg isnt covering the bottom fan and my temps are actually below 50 (cpu and gpu). I don't believe my issues are related to heat whatsoever and if I were to have the 9-cell battery my temps in all cases would decrease by about 5 degrees (simulated by propping the back of my unit up a few cm like a 9-cell battery would).

 

If thats the case then you could just be saddled with a bad motherboard/power adapter. I just replied to someone who posted their TS log and screenshot here (check the bottom of the page)

Seems to have a similar spec to yours (5730 GPU) and despite having stressed his system for 42 minutes, there is no sign of throttling - and his temps are breathtakingly good. This leads me to believe that your case is one of a minority, and you should probably talk to Dell, either to replace your system, or atleast to send someone out with a new motherboard and adapter.

On a side note, have you tried using ThrottleStop? What happens when you check all three (Multiplier, Cmod and ChipM)? Does the throttling issue go away?

 

It's a shame you can't undervolt these... Yet!?
My T9300 idles at about 35degC maxing out at about... Well under 50degC anyway...

Is anyone working on this?

 

Machine spec: Dell Studio XPS 16. 8GB, i7-820qm, 256GB SSD.
Measured temps: When waking up from sleep: 50-55
In Idle time: 68-72
Gaming: Very strange, temp is lower than idle... around 62 Celsius.

BTW, talked to dell this morning... and they will replace this machine

 

Hmmm I have the same processor and I got it in November last year when the 1645 first came out. My idle temperatures are 50 C across the board (CPU, GPU) and 70-ish C under gaming stress. You tried cleaning your fan or applying some thermal paste? Maybe the thermal conduction paste between the processors and the heat sink is gone, so heat transfer is less than optimal.
