    Especially the 6224 and 6324 as they have a very small heatsink (the actual finned area- not the whole assembly).

    Does this apply for the 6625 model ?

    What the heatsink being small, or the nVidia report? The heatsink on the 6625 is better/bigger than the one on the 6324/6224 so you shouldn't have the cooling problem the 6324/6224 users have. However, as nVidia have not released details of which GPU's are affected there is no way to tell if it is related to the 8600mGT ingeneral. We will just have to wait for Zepto to confirm either way.

    i have been growing increasingly concerned about the temperature of my GPU in recent months...I have a 6625 bought in November '07. I use it occasionally for moderate gaming: at first when gaming for 30 mins or more the temp would edge up to high 70's early 80's during half life, guild wars, heroes of might and magic 5 etc...however I'm now hitting 95C and am slightly worried...while performance is still fine I just feel it shouldn't be this hot and i don't want to reduce the life span of my laptop! its gotta last uni for me at least!
    SHould I send it in?

    I have a 6214W also and it runs at about 98C when gaming. No problems yet. It's been running since i got it almost 2 years ago. I play WoW about 3-4 hours a day when i raid in the evenings, so it isn't because I don't play games at all on it.

    But is that an 8xxx series GPU or something older?

    What I've read about the nVidia problem suggests the problem is with the packaging of the 8xxx series.

    They say it's a thermal issue, but won't say which models.

    If it's a 6214 he is using, it must be an Go7600 512MB. Not a GPU from the next 8xxx generation.

    Like John already mentioned, I have read the same thing; it's only the 8xxx generation GPU's that's affected.
    They aren't clear however whether it's the 8600 or 8400, DDR2 or DDR3 models.

    My HP laptop is in for repair because the GPU failed as a result of heat damage, if that offers you any info. It also causes the nearby wireless card to fail intermittently. Both of these issues have resulted in HP issuing a warranty extension on several of their models.

    My 6214 (geforce go 7600) is dead, the graphic card issue (graphic corruption, not working with drivers...). Maybe it's somehoww related.

    the news doesnt include any 7xxx card, so it might be another problem

    My 6224w with 8600m GT was running with GPU idle temperature around 71 degrees. Just opened up the laptop two hours ago and removed the the heatsinks to find out there was way too much thermal paste applied on both CPU and GPU. Cleaned the old thermal paste and applied arctic silver paste, now it is running at 65 degrees when idle. Hopefully this will cool down my laptop a bit. I was a bit disappointed to see that amount of paste on the CPU and GPU.

    @evren: same for me.
    Zepto must have used a whole tube of AS5 on my gpu and cpu.
    Im also ilding on 65 on the gpu now...

    what's your idle temp on you cpu? im at about 50 degrees running on 0,9V and at 800 MHz

    @Megatron & everen: Do you have powermizer disabled. I idle between 40-55C using 174.12 drivers with powermizer enabled. If I disable powermizer I can get 65C ish idle. I am currently using 174.12 drivers as they are the only ones that don't cause significant downclocking during games. (they dip to 275MHz core for 4 secs then return to normal about every hour or so of gaming) All the other (newer) drivers cause me to drop to 275MHz after about 2mins game play and don't go back up until I reboot the PC.
    I too found way too much AS5 on my heatsinks, after replacing my idle didn't drop much but the max dropped by about 10C-15C which is a huge decrease. I haven't undervolted my CPU as I can't get rmclock to play nicely with my other programs installed. But then I don't have a problem with CPU overheating. (max 80C when gaming/electronic circuit simulating).
    I still feel that the heatsink in the 6224/6324 series is seriously inadequate. I will do some searching about and try and find a way to increase the surface area of the heatsink, when my warranty ends (next month I think).

    @AndyGB40 - Thanks for the suggestions, I am not sure whether my powermizer is enabled or not. I will check this tonight when I go back home. But I must say, I've never seen idle GPU temperatures anything lower than 60C in my 6224 before. I will also check my driver version and update it as necessary to see whether it'll make any difference or not.

    @Megatron - I have undervolted my CPU below 1V (I can't remember exact voltage) and it reduced the temperature greatly. As far as I remember, my idle CPU temp is around 30-35C, goes upto 50-60C when under load. I will check them and post the results later tonight as well.

    Ok, just checked and unfortunately it is not great news in my case :( The powermizer is already enabled and currently my idle temp is 69C. My driver version is 177.98. My CPU is doing much better tho, idle temp is 39C.

    I really don't know what else I can do about it. It looks like I'll end up giving this laptop to my sister within a year's time and get myself a Dell XPS or MacBook Pro :(

    I tried to reapply it but I had a problem when taking out the heat sink and putting it back in. I couldn't take the case apart completely so to take out the heatsink I had to flex the case and had to do the same when putting it back in. I have removed the old grease and reapplied a new layer on it but it might have not worked properly because of my trouble with putting the heatsink back in. I tried my best to put it on proerly but I'm not sure whether I was able to do it or not. I couldn't open the case completely because one of the small screws at the slot drive bay, I just couldn't take that single screw out :( I tried to find a step by step guide showing how to take the heatsink out but couldn't find it in the forums, only a guide about taking the keyboard out. Gosh, I hope I make some sense :D

    @evren: yeah you make some sense :)
    I had a little trouble removing the heatsink for the cpu too, but i removed some screws, under the laptop on the left side that was holding together the case, witch made it alot easier.

    See, I couldn't remove one of the small screws on the left handside. It was too tight initially and I kinda screwed up the head of the screw :( I have no idea how I'll be able to take that single one out. I might give it a go tonight and see.

    Hmm doesnt sound so good, but you could try a very small flat screwdriver. I've found that they work pretty good when the phillips-head is no use.
