    Hi to all, I´m from Spain, and I have a xmg p502 (clevo p150em).
    I think I could improve the cooling system making more and bigger holes in the bottom case to allow more airflow get in the fans.
    However, it´s still with warranty, so that I´d like to buy a new (or used) bottom case to make the mod.
    Doed anyone know where I could buy it??? I´ve been looking up in ebay for months, but Ihaven´t been able to find anyone.
    Thanks for the helping.

    A few years ago a member tried this with a previous model and it actually made the temps worse for some reason.
    What is your ambient room temperature and do you clean the fans and vents our often with compressed air.
    Also what temps are you getting for cpu and gpu when just brousing and while gaming.

    Thanks for answering.
    The temps aren´t worring, playing batlefield 4 or max payne 3 (for example) cpu is under 70ºC and gpu around 75-80 (room temperature arround 25ºC).
    However, nowadays I´m playing Crysis 1 (with natural mod) and unbelievable gpu is arround 85ºC (it even reaches 89ºC, despite being an old game). (cpu keps the shame temps)
    I´ve made the foil mod as well, but I believe If I managed to get in more air in the case, specially in the gpu zone, the gpu temps would get better.
    Don´t you think the shame?
    The fans are clean.
    Sorry for my English, I´m leraning :)
    Thanks again.

    amd gpu? 89C is not worring. within normal range. in fact amd card can get faulty even the user already taken very good care.

    If you are making extra holes that's where ramsinks and a cooling pad make a difference.

    Ok, thanks to all.
    I´d rather not to put on neither ramsink nor cooling pad, because it would void the warranty.
    I know the temps aren´t worring, but I´d like it to be better. (my hadware is i7 3630+amd 7970m)
    I´ll coninue seeking a bottom case... (I´ve only found one from EEUU, but I don´t want to take risk with customs taxes)
    Thanks again.

    If you are boring holes into the plastic the warranty is the least of your concerns and a cooling pad/stand can be used at any time.

    We've seen some try to make this mod on one or two particular models in the past and the perspective is a bit misdirected. Perforating part of the chassis has worked in some cases for some users, but we've also seen it disrupt how the air is guided and consequently, like you said, make things worse.

    Thermal design is not as easy as people think.

    Have you tried playing with the backcover off? to see if the temps are worth it? And instead of drilling holes, just take the cover off (If your temps are worth it) and leave it on a cooling pad. That's what I do and it's great.

    Ok, then I´ll give up this idea.
    I´d rather not to take the cover off, as it would allow to get in more dust inside the laptop (fans and so on), and below the bottom case there are the feet of the laptop as well.
    Indeed, the temps aren´to too worring.
    Thanks to all again.

    I would just prop the back up a little, repaste and repad if the temps are still too high for your liking and not go crazy unless you want to benchmark it to break high scores.

    The thing with BGA chips (Such as Nvidia chips) is that while there is a direct relationship between heat and life expectancy (Expectancy being the keyword here) you can never know if it would have failed if it were 20c cooler than it was running. This has existed forever, you may have heard the Xbox's infamous 'Red Ring of Death'. Most problems with BGA chips is that they run hot, therefore expanding the brittle Lead-Free solder holding it to the board. Now the problem with expanding and contracting brittle materials is that they are likely to crack at some point, in this case is would be a crack the size of a hair on a solder joint. ( This is the definitely not the only cause of faults, but certainly the most common)

    The other common problem is breaking the inside of the chip, and every chip is different (Which is why I asked on another thread the voltage limit on the 780m, I was just curious).
    But breaking the chip itself is in fact very hard to do in modern electronics..But it still happens. And the solder joints I spoke of earlier are not even part of the chip, they are just the connections. (A Chain will break if just one link is weak).

    The Chips are meant to be run under the max temps specified by the manufacturer. For example the desktop 780 GTX Chip can run up to 95c without causing damage ( And bear in mind Nvidia ONLY make the chip itself ). So the people who buy the chips and put them on circuit boards (turning it into a graphics card) such as Evga, Asus and MSI have to make the chip run as cool as possible to stay under the 95c preventing damage to the chip.

    The Solder balls underneath the chip Will without a doubt fail at some point, it's just most people upgrade by then. 50% of my job is to repair these solder balls underneath chips. because most of the time, the chips are fine. So if your card does break while under the safe temps (Notebook chips are designed to tolerate quite high temps, and most will throttle anyway) and your warranty has expired. It is worth noting that the chip is fine 90% of the time but just need to be Reflowed OR Reballed back onto the board. Good as new

    Im not sure if you even care about this stuff :) but I thought I would write it down anyway, this is just my experience.

    I have widened the air intake holes on the bottom cover of my P170EM to about 150% of their original size with a small flat file. It lowered my load temps by ~4C on both CPU and GPU.

    That's great :) I can get kinda carried away when I start typing sorry.

    I wish I was doing this a year after the Xbox 360 came out, you could make soo much money. I guess when the warranty runs out on the PS4 and Xbox One, I will start getting a lot more customers.

    Dude, make a thread in NBR Marketplace subforum instead of shouting "I have parts!" everywhere...
