HP Pavilion 15-p036tx cpu "overheating"

[thescorpions]

Hello, I have HP Pavilion 15-p036tx. The problem is with the CPU - i7-4510u, it gets overheated, temperature sensors shows very high temperatures (as I'm typing this post HWInfo64 says that CPU temperature is about 57-60C). It's been 4 years since I bought this laptop and I used it a lot for gaming (Battlefield 3,4 for example) and during this period I changed thermal paste and cleaned my notebook from dust few times. There was a time when I had to do it due to the auto-shutdown because of overheating. But when I changed thermal paste and cleaned everything was good. But this time it didn't help.

About overheating. As soon as I run some serious app (like 720p YT video) or some game sensors begin to show 97-99C in (literally) 1 minute. And the interesting thing starts from this moment : the cooler is very loud and blows cool air (not even warm), as I touch back plate it also doesn't feel like even 70C (I know what I'm talking about because I used this laptop for games in the summer). The laptop doesn't auto-shutdown due to the overheating and can work with 97-99C many hours. I must notice that I checked heat sink system and it provides warmth to the radiator. 

And it wouldn't be a problem if there wasn't such thing as throttling that recudes CPU frequency, and when it comes to 97-99C frequency varies from 800Mhz to 3000Mhz (and it does very fast, I use MSI afterburner to monitor frequency). Obviously it leads to awful FPS drops in games. a GPU (geforce 840m) on the other hand feels good - it's temperature is about 65-70 at the same time when CPU reaches 97-99C.

To prevent you from some types of helping comments I must say that I tried: 

* different OS (Windows 8.1, 7, 10)

* updating drivers and updating BIOS (of course official versions)

* cleaned it and changed thermal paste.

* to check my CPU (and other components) with HP PC Hardware DiagnosticsHP

The one suggestion from me : in the first years of use the air also blew through keyboards but now it doesn't. How do you think - is there any bond between momental over-heating and this fact?

I called to my local official service center, they said that this exact model isn't supported. The problem isn't typical so I didn't try to go to unofficial ones. 

I think maybe the problem is with temperature sensor and I would like to know is there only one sensor in the CPU or there's another one on the motherboard? 

I will be very glad if I get some information about it. Thanks in advance. (I hope I've chosen the right section).

In addition I should say that HwInfo64 says that "power limit exceeded : yes". Is there a way to fix it?

I fixed my overheating issues. After 2 years of hard research.

The number one priority should be to cleaning dust from the laptop from inside. Assuming you have cleaned it and the overheating still persists:

1. Buy a cooling pad. Helps but doesnt entirely fix the problem.

2. Open the task manager and click the Performance tab. Under CPU check if the CPU speed is higher than your laptops specifications. e.g mine is Core i7 CPU @2.40GHz  yet my CPU speed was around @2.90GHz sometimes @3.00Ghz. this is normal for most laptops. Its called 'Processor performance boost mode'. I underclocked the CPU to @2.40 and no more overheating issues. If you wanna do this there are 3 ways:

      2a.   Go into windows power options > Processor Power management > Maximum processor state > lower it to like 80%. (this has worked for many people but not me personally but it might work for you)

     2b.  Download 'Throttlestop' and open (no installation needed) Untick the option of 'SPEEDBOOST' and click save. (I dont like this option as you have to do this every time you turn your laptop on. But it works.)

    2c. This worked for me: I downloaded a registry file that added an additional option to my Windows power settings. Below above mentioned 'Maximum processor state' there is a new option 'Processor performance boost mode' and you just disable it. For some laptops you can enable this option in BIOS. For me I had to download a registry file to get the advanced power options. This is a bit advanced and I do not recommend it if you don't know what you're doing but if you want to do it google this or ask me.

I hope I helped.
