    P-7811 FX Overheating GPU

    At idle, my GPU runs around 60-65 C, and during a quick vent in L4D, it jumps up to 107 C.

    What I want to know is if it is possible to take apart the cooling and apply some Arctic silver to the GPU. I've got the laptop propped up so that's not the problem. However, it's extremely hot when I'm playing a game.

    Anyway, I really need help to fix this if anyone can lend me a hand I would be greatly appreciative.

    How you tried compressed air on the GPU vent?


    Yes it is possible, there should be a guide on the forum somewhere. Be careful- you can easily break/lose something when taking it apart.

    I've not tried compressed air yet. What vents will I have to use the air on? Is there a picture/guide? I'm going to go purchase some compressed air and KFC chicken. The KFC is just for a snack because I'm hungry. Hahaha.

    Thank you for helping me so far Deron.

    If you want to be lazy you can just use compressed air on all of the vents.

    However, if you want to get down a dirty take the basic components off and cleaning out the vents and heat sinks will be your best option. (My temps got fairly high until I cleaned out my vents/heat sink)
    The guide is actually a sticky
    http://forum.notebookreview.com/showthread.php?t=382408

    You'll be surprised how much dust and what not is trapped inside the heatsink.

    The thing is, is it safe to use AS5 on it? I've heard different opinions on some saying it's too thin and that IC Diamond 7 would be the way to go etc etc. I want to actually take off the heatsink and such. I really don't want this laptop or the GFX card to die on me.

    I had the same issue Shamrock. My CPU temps would get up to 110C and my video would start to spike. I followed a guide that was here on the forums, completely took the laptop apart and applied ICD7 on the CPU, mobo, and GPU. While I was in there, I cleaned out a nice big wad of dust from the CPU fan as well. Since then, my GPU rarely gets above 70C, the highest was 75 on one occassion.

    I highly recommend applying ICD7 to your GPU, it saved my 7811 from a brutal demise via stairs. Just be sure to do your research before hand.

    Do I have to take apart the WHOLE laptop in order to apply thermal paste to the GPU? I don't think I'm going to be able to do that. I've never taken apart a laptop before.

    Sorry for double post, but is it safe to use AS5?

    It should be fine to use AS5, I wouldn't see a problem with it.

    To get to the GPU, you have to take apart a lot of the computer. The CPU is much easier, though.

    I have a similar issue (except I have a P-7805u)

    My temperatures at idle for my GPU are around 50-60, however once I fire a game up after a bit of gaming it quickly jumps up to 90-105 range depending on elevation of my laptop.

    I like Shamrock would like to fix this problem, however I've never taken apart a laptop and after looking at the sticky at the top of the forum it looks like quite the undertaking.

    But from what I've read ICD7 seems to be the solution.. it's just getting to the GPU..

    The CPU is simple to get to, but to access the GPU you literally have to take the entire machine apart. Like I said, there used to be a guide here on the forums which described, in detail, the complete process of taking a 7811 apart, which should be the same as the 7805. I've built several desktop computer, but that was my first time taking apart a laptop. I was very nervous, but I got through the entire process without any issues.

    My gpu and cpu averaged over 90c-106c during game play like fallout 3. I then took one day and spent a few hours taking my 7811 apart and cleaned the vents with air and cleaned the fan blades with a q-tip.WOW what a difference in temps.My gpu maxes around 60c and my cpu around 55c.Just take your time its worth it.Also it stopped the lock up during gaming.

    In the picture, I would remove the thermal pad on the chip just above the memory modules. Clean the paste off the CPU and heatsink then use ICD7 on both the CPU and the other chip (I think that's the northbridge chip). I haven't done this with my 7805 yet, but I think the GPU is located on the right side, under the vent openings so you still have a lot of disassembly to go if you want to reach that.

    Putting paste on the memory chips won't help, there's no heat sink to take up the heat.

    Okay, I just had to post something about this...... I don't think that it is the GPU, Northbridge or Southbridge overheating anymore.... why? Because I checked their temperatures, and when I am getting hard-lockups the GPU is a little above 83 degrees and the two other chips are BARELY warm to the touch...... but the CPU temperatures are out of control, with them almost being the SAME as the temperatures of the GPU when a stressful game is running.

    Now, does the heat from the GPU get SLUUUUUURPED over to the CPU somehow? That would explain the CPU being basically cooked to death and causing the lockups.

    Or is there something else going on here? I'm assuming it's the former, that somehow the cool air is pulled from the GPU side of the computer through a... pipe or tunnel in the case, and then is exhausted out the other side?

    Edit: Okay, and I'm going to look like an absolute IDIOT for admitting this.... but I had the GPU and CPU mixed up. The CPU is staying nice and cool, I kept the thing open and propped up while running a game.... CPU stayed cool enough that I could touch it. GPU on the other hand.... the 'copper grill' burned me when I touched it..... I cannot even reach it to really try to clean the GPU out well, because it would mean disassembling the ENTIRE DAMNED COMPUTER.... which is a pain in the rump, to be honest.
    Does anyone have a link to a 'disassembly guide' anyway? Maybe one day when I am bored I will try to disassemble this thing and clean out the GPU REALLY REALLY well.
    I will state one thing however.... next time that Gateway makes a computer...... they need to put a limiter on how hot the GPU can get before it starts clanging out "WARNING, WARNING!" and just dials back the clock on the thing.
