    I've been doing a fair amount of research, and after looking for a long time, I went ahead and brought this laptop.


    The thing that attracted me the most about this laptop was the fact that it had Thunderbolt, and an Expresscard slot just in case I wanted to use a egpu.

    As soon as I received the laptop, I powered it on and immediately noticed that the fans were blowing at full speed. It didn't worry me because I thought it was normal, I mean, it did have a lot of parts to power. I ran Core Temp on it, and while it showed temperatures at 45 degrees during idle, I tried gaming on it and the CPU temperature almost automatically hit 90 degrees, hitting 100 degrees as well. I feel as though the laptop was even suffering from thermal throttling as the CPU frequency was fluctuating a lot during usage.

    I always kept in mind when buying laptops/computers that I should keep an eye out for great processors, and I heard a lot of great things about the power 4930MX/4940MX offered, but I never once considered the thermal management that I would encounter.

    I did some research on this forum, and read how this is a normal occurance with Zbook 17 laptops. I never knew anything about this, as all I was interested in was the CPU power, and connectivity the laptop gave me.

    Is this laptop worth keeping, and will it last, or should I return it while I still have the chance?

    Thank-you in advance.

    You should give it a full teardown, clean the heatsink and repaste, because it shouldn't be running fans at full speed at iddle, and if the temps rise to 100ºC it seems like the thermal paste is all dried up.

    I might've typed that wrong, but the fans are okay whenever they're idling and the temperature is usually at 40-50 degrees. It's only whenever I put the CPU to work by playing games that the CPU usage jumps to 100% and the temperatures rise to 100 degrees.

    I tried to open the laptop up with my screwdriver, but it was pretty tight. and I couldn't open it up. Any recommendations as to where I should buy a laptop to screw driver?

    What you're getting at though is that I should keep the laptop, and this problem is nothing to stress about even if it means asking for outside help to open up?

    I really appreciate the fast response, because I'm willing to do anything to keep it and not just ship it right back

    Any Philips PH0 and PH1 are all you need to take a laptop apart.

    Your laptop model is very popular, so there is lots of teardown videos on youtube, watch a couple first so you know where are all the hidden screws and what order to take it apart.

    I reapplied thermal paste, blew air through the computer, and now the cpu is maxing at 90-94 degrees now.

    Is this still something to be concerned about, or 90 degrees safe

    The CPU is hitting 99 degrees after playing games again....

    Should I keep the Zbook, or return it?

    What would you guys do

    HP? Gone in 60 seconds...

    No excuse for this, return it while you can.

    What paste did you use?

    Have you already undervolted your CPU?

    The usual CPU's used on those laptops have a 45W TDP, yours has a TDP of 57W, its expected that it will hotter than the more usual CPU's, so undervolting is a must.

    Depending on the price it might be worthy to keep, its a still decent CPU, and you can upgrade the GPU given that its still a Kepler gen one that also runs hot..

    I got the paste from a friend of mine, and it didnt have a label (funny you asked that).

    I've searched for the undervolting guide on here, but i couldn't find it. Do you remember which thread it was?

    Download ThrottleStop and drop it like -50mV and start working from there.
