Hi.

 

Just got a Predator 15 G9-593 with i7 7700HQ - GTX 1070 ect.

 

Under BF1 the GPU is very cold like 55 but the cpu is hitting 90 and 97, but cpu are still running 3.5/3.8Ghz.

 

I do not like the hot cpu. Shall I put some new thermal paste on it, and is there a video so i can see how to do it?

 

I will hate sending it back, i really love everthing about it.

 

What do you guys think?

    There is verry little point not to undervolt it a bit, you lose no performance at all, you also should get a bit more battery life.

    - 0,120 is a verry prudent ammount for 6700hq, the stability shout not be affected at all.

    They use verry bad paste, I changed mine and it helped a lot.

    If you think you can manage to repaste it go for it, there is a dissasembly video but without the heatsinks, however, if you get to the heatsinks, removing them is very easy.

    Perfect.

     

    I have seen the video and think i can manage to take of the back cover and unscrew the heatsink and put some new paste on it. I have some grizzly thermal paste i will put on. The GPU is very cool and never get over 60 in BF1 but the CPU is very bad. I will try repaste it and see. Thanks. Smiley Happy

    grizzly is supposed to be great, I only used some artic mx2 and still shaved off about 20 degrees when stressing the cpu with prime 95

    Great then I try that.

     

    But what i like is that even when the cpu hit 97, there is no cpu throttling, but some core just hit 76 but the other 85 to 97.

     

    I will post something when I repaste. Smiley Wink thx.

    I had the same problems. I solved the issue in two stages.

    1: Repaste. Arctic Silver 5

    2: Lowered the core voltage by 0,120 v(Intel Extreme Tuning Utility)

     

    Result?

    Seperate test

    CPU temps from low 90's to low 50's (Prime 95)

    GPU tems from low 80's to low 50's (Furmark)

     

    Stressing both CPU and GPU at the same time(Furmark + Prime 95)

    CPU from 95 to 60

    GPU from 90 to 65

     

    Repasting alone gave - minus 20, reduced voltage the rest.

    Take a look at this.

     

    I remove the old pasta and put on some new thermal.

     

    In BF1 when the cpu hit 87-95, now i see it in 70-73 its awesome.

     

    Prime95 maks temp is 78 i love it. Smiley Happy

     

    The GPU is still cool, around 58 in BF1.

     

    All the temp are with normal fan speed, no max so that great. Thanks for the help. Smiley Happy

    Nice work. Undervolting the CPU will probaly reduce the temperatures even further.

    Thansk.

     

    Im fine with temp under 80. Smiley Wink

    you right.

     

    just got i 0,120 volt under and drop 5 degress in BF1 and prime95. thats great. Smiley Wink Love this machine. Smiley Very Happy

    Hi, you never faced a problem when intel xtu stuck on your down-voltage as default and won't allow to apply your profile, I had to use bat file:

    Would changing the thermal paste void the warranty? I see no stickers on the back of the laptop and also the teardown videos showed nothing whatsoever that would indicate that the warranty would be voided.

    Nope. Just be careful there, and that's it.

    My predator from the purchase was twice in the repair. They exchanged the motherboard twice. Temperatures 97-101 now after two days are supposed to be max 85. I would like to exchange the paste but you can not :/ because the guarantees are lost.
    They advertised great cooling, interesting where it is because certainly not in this laptop :/

    Hi,
    If you don't want to repaste due to warranty restrictions, why not undervolt it and see whether it reduces the temps? It's safe and will not impact the performance.

    The first one wants to test the laptop if it's ok. Then I will reduce the tension and probably put a paste. Service in poland is embarrassing, since the purchase immediately two repairs. The laptop is quite expensive and immediately the service: / and I could buy something MSI: P I asked the service if I could apply the paste myself and I got the answer that it is not because I lose the warranty, and they put some cheap ***** into an expensive laptop.

    Well, the temperatures returned after repair to normal: / Twice it has been serviced already.
