7520 and thermal throttling

Hello all,
I wonder if anyone else has seen this and if it is normal. I have the 7520 with the 7700hq processor and m1200 graphics card. When i do a stress test of the cpu and gpu i am seeing temperatures of over 97 c on the processor and it throttles at up to 10 to 20 percent. Don't think i did the test with the gpu when i got it but it doesn't throttle with only cpu testing.
Just got the machine back from dell after getting the main board replaced due to it causing infinite blue screens. Don't know if this is normal, or if it needs to be repasted. Or if i should just complain to dell again.

 

Sounds like it is getting a bit warm for comfort. However, this was during a stress test which is designed from the ground up to push the system to absolute max. You will likely not see temps like that through normal use. Use it as you normally would for a couple days and pay attention to the temps throughout the day and see what they do. If they still get high (id say 75C or hotter) under standard use, then you may have an issue. What do you typically use this machine for? And are you sure the CPU is the 7700hq? That CPU doesnt have either vPro or Trusted Execution. It doesnt seem like something Dell would offer in a Precision, but I could easily be wrong.

That being said, the cooling on the new models probably isnt as great as the older models like the M6800 or the M4800 because they arent as big or as heavy. The cooling in these older models was about as good as it could get in a laptop.

 

I normal use it for coding and occasionally work with Adobe for video editing and encoding. The encoding is very resource intensive. The i7 7700hq is the correct processor. I'll give it a few days to settle in and see how things run and follow up.

 

I’d almost be willing to bet that the encoding won’t get it as hot as that synthetic benchmark did. Next time you do encoding, watch the temps to see if they get as high as the stress test made them get.

Just ran another encoding task on it today. You were right, it didn't get quite that hot but was still seeing low 90s. Compared it to a identical 7520 my office just got and the new one with the same task barely cracks 80. With the synthetic test it peaked at 92 and never throttled. I'll give it more use over the weekend and see how it is Monday. Probably contact dell again it if it doesn't get better after settling in a little bit more. Since i know it takes a little for the compound in there to even out.

 

Don't be afraid to contact Dell, those laptops come with business service and given what they charge for them, you are entitled to the service and a machine that doesn't throttle.

 

Oh I'm not afraid. I just don't like it. Dealing with them is like pulling teeth. Thankfully i don't need them that frequently as i am a computer repair tech, even after i tell them everything i have done they give me a hard time.

 

Here is an example of what I am seeing when I run the tests. When doing actual tasks it still hits about 95c outside synthetic tests

 

Return it or re-paste self. The best is fix it by yourself. As you can pick the best thermal paste out there vs. the low quality thermal stamp you will get from Dell.

 

Was thinking about doing that but didn't want to risk warranty as less than 2 months old.
They did send out a tech today with a new motherboard and heatsink fan assembly. After they replaced that it is definitely running better. Under full load it averages in the mid to low 80s now. It parked at 91 but only very briefly and didn't throttle at all. So it is running much better even right after the work before the paste could really even settle. The tech also thought it could have been the controller on the board. I still lean to it possibly being bad paste or loose. Compared it to the new unit we just received on Friday and it is running cooler under the same load then the new one does.
Although if it does start getting warm again, I'll probably pull it apart myself and put in some artic silver 5.
