m15x copper mod and other cooling mods

Hi just wondering if anyone as tried the copper mod on the m15x GPU or CPU ? Is it easy to do and does it help ?
If someone has done this then could I get some guidance because I would love to try it out. I am in the UK so what type of copper plates would I need and where should I try getting them from ?

Would it also be possible to replace the m15x fans with some higher cfm/rpm fans ?

 

I have not tried it yet. My m15x already has adequate cooling.

 

Get a tube of ICD24, cheaper, easier, and will probably perform better.

 

There's no need, the m15x already has great cooling. Also, isn't it for gaps normally filled by a thermal pad? The heatsinks will likely be with copper touching the GPU/CPU already in which case a copper mod would have no help.

I seriously doubt that you'd be able to get any part of the fans changed.

 

I know the m15x has decent (not great) cooling anyway but anything to boost the cooling system cant hurt can it ?
Can anyone who has opened up the m15x confirm if there are thermal pads in between the GPU and heatsink, just to make sure the copper mod would be of any use ? Also, what are the dimensions of the GPU and CPU chips so that I know what size copper sheet to get. The copper mod says 14mm by 14 mm for the 8400 gs but I guess the 8800 gtx would have a larger size ?

 

There is absolutely no need to copper mod the m15x. The copper mod was done to the M17 northbridge to fill a gap between the northbridge and the heatsink when using a quad core processor. The northbridge was suspected of overheating due to a gap between the chip and the heatsink that was filled only by a thermal pad. The m15x doesn't have this configuration, and as stated earlier, already has adequate cooling.

 

Copper mods are done on gaps generally normally filled by thermal pads. Seeming as the copper heatsink is actually in contact with the CPU and GPU, it would not only provide no benefit but would also possibly damage your heatsink and components if you tried it, as there's no gap.

 

Hmmmm so the m15x doesnt have any thermal pads that can be replaced with the copper mod. Are there any other cooling mods I can try ? Im really itching to fiddle with this. How about replacing the Thermal paste with OCZ freeze to cut a couple of degrees ? I also read somewhere that you can file down desktop GPU memory heatsinks and stick them to laptop ones to help with the cooling ?

Im getting the modding bug just like I did with mys desktops

 

Heh, yea the old modding bug...

Anyway. You could replace the thermal paste to cut degrees down by quite a bit. You may be able to use the Zalman VGA RAM heatsinks, but I don't know what the design is on the fans so they may not fit.

 

What thermal paste does the AW use ? I heard it was generic silver paste when people opened it up during the whole overheating issue. Some people mentioned that in most cases excess paste was used, so redoing the thermal paste seems like a good idea, only, Ill have to keep some silver paste handy incase I need to send mine back to AW. Will look into the vga heatsinks

Edit : Which heatsinks would be better ? The ones with a few rows of 'fins' or the 'spiky' type ones ?

Anyone who has opened up the M15X, is there palce for these ?

 

Which one of these would be better ?

are you trying to get the best cooling out of you m15x??????

take a picture of the bottom open and unopened. also i need to know your system config, and if you are using a cooler yes or no.


also can you run dmc4 2 times for the gpu, run cpustabtest for 15mins and post your results using hw moniter.

do this with and without a cooler and we can see if you need cooling methods or not.

 

having recently baked my gpu, i can confirm that there is NO thermal pad between the heatsink and gpu... it was just thermal paste. however, there are thermal pads between the gpu's memory units and the heatsink.


whats interesting is that the MORE thermal paste i put on, the better it cools. i've been reading that 'a thin coating' of thermal paste does the best job... this was NOT the case for mine.

 

Due to not having 100% thermal efficiency, more thermal paste will cause temps to rise.

With that said, if the heatsink plate is even slightly askew with the die, then the uneven gap must be bridged. Ideally, you want to ensure the two surfaces are perfectly parallel. I suspect your two surfaces aren't exactly parallel requiring you to use more paste.


Also, take a look at my How-to linked in my sig if your graphics card is dead. You may be able to easily repair it.

 

ya I read that link, would NEVER guess that haha. props for figuring it out though.

 

Hi Rob41, I am suspecting of my surfaces to also be not perfectly parallel. Whenever I apply and spread a thin amount of AS5 onto my gpu, the gpu almost always overheats to 108c. And upon inspection of the gpu and heatsink, I notice that 95% of the thermal paste was still on the gpu and only 5% made contact with the heatsink.

My only option is to apply more thermal paste for better contact. Would u know of any other ways to fix this problem? Maybe buy new heatsink from AW ? Or do some type of modding perhaps ? Thanks in advance.

 

Take a picture of the you cooling and we can see what can be done.
