UPDATED:ASUS G51J-A1 copper/case/cooling pad mod with 920xm!!!

Note of working in progress I will touch this up later when i got more time and fix grammar and make it neater
I just added photos of temps with my GTX260m overclocked and a 920xm at 26 26 25 25 with TDP 85 running folding at home. Note I put in the new fan and have it running at 5v constant by external power source. The fan was not an exact match and I had to cut out the old fan and dremmal a matching hole to super glue it in. The cord was also too short so I had to go with an external power source. I am running at 65-75C GPU depending on room temp and 76-85C for cpu. Also you have to have a 180w psu with 80-85TDP because I was bricking my new 150w PSU. I will add more photos and more info later in the weekend or week. I have photos on how to apply ICD and how to replace the fan and everything.

Currently working on a water cooling mod here I will update this thread with all results once I finish. It'll be a few months because I am working out a lot of details and possible methods.


Well just tried hardware mod of my fan and it worked! It is rated at 5v so i tried 6v because thats all i had on hand and its brushless motor so i was like that'll work. well it did so i tried 12v and 13v and it went pshh fizzle poof.....brushless motor my rump. Don't go higher then rated voltage if brushless motor...maybe can get away with 1v but not anymore....make sure you have a back up cooling system...i haven't got one yet and that was a mistake. Luckily my cooling system is modified enough to handle basic functions and hold decent temps. I also have gpu underclocked and throttling on to be safe...monitoring it carefully until i get new cooling system

Alright so I finally got around to modding it and finished. I have done everything forge has done and some more. As everyone knows with the G51J you hit 105C and throttle in a couple mins trying to run prime and furmark at ASUS stock clocks. When you disable the throttle put in place by ASUS. I have listed my new temps below. About a year ago all I did was the case mod and that allowed me to overclock and play games at 90C which was nice. Although now I have finished all the mods and it is awesome!!!

Things I have done
1.)ICD24 has been added
2.)Bottom of the case has been drilled to high heaven
3.)Bottom case fan intake has been nearly fully grinded(sp?) away
4.)Have added copper heatsinks to heat pipes and heatsinks.
-I did not add as many as forge because I do not like the heatsinks not fully touching. Many spots only have enough room for half of the heatsink to stick to and I don't feel comfortable with having it part on and part floating. I don't like the chance of a conducting mettle floating around. Also I did not put heatsinks on the parts that I could not fully clean because again they will not stick as well and I don't want to chance it. Also I used the SEKISUI thermal tape. It appears to stick and conduct better then the stock Sony tape. The Sony tape seems to work fine but forge said SEKISUI is better and it appears to conduct more from a couple tests I have done.
5.)I have modded my cooling pad to use 3 92mm Vantec Tornado fans. At 12v and 1amp(?) they put out 119CFM. I am right now using an AC adapter that is 5V 2.6amps So the fans are probably running at ~40% capacity, which is good because they are still very annoying . They are still quite loud but I bet they are pushing still ~150CFM, which is much better than the unnoticeable maybe 10CFM the cooling pad was doing. The cooling pad btw is a Rosewill from Newegg.
-I took a 12V legacy cable that was laying around to extend it a foot(the fan cabled from cooler) and then cut and spliced a 12v rail off my old PSU from a desktop. I attached everything so that I can unplug it when I want to and attached the 12V rail to the AC adapter that I also spliced.
6A.) I replaced my fan with almost identical fan and have it powered at full speed (5V). Night and day difference in temps.

Few more possible mods I have not down due to laziness and too difficult.
6B.)Moral Hazards registry hack for the case fan. (I most likely will be doing this I will be throwing in a 920xm and overvolting my gpu for even higher clocks)

7.)Pelter cooling mod....possible but a pain.
8.)liquid cooling...get a desktop
9.)a few others i haven't listed yet because they are just dumb

Don't have screens shots because I never took any before I started.(note this has the standard Rosewill cooler with no mod)
Temps before mod.
Using ASUS stock clocks of 500 core 1250 shader and 800 memory with disabling throttling you would hit 105C in less then two mins running Prime and FurMark
Room temp back where I used to live were like 64-74F.

Don't have screens shots because I never took any before I finished. (note this has the standard Rosewill cooler with no mod)
Temps with case drilled mod
I drilled the case and fan intake...drilled/cut/grinded(which ever method you use).
I could run Prime and FurMark with overclocks 580 core 1450 shader and 950 memory and hit ~90C give or take depending on room temp, which is a huge increase with just a quick and easy mod.
Room temp back where I used to live were like 64-74F.

Temps after I finished with everything listed above
I don't have room temps because I don't have a temperature thing but it is quite warm right now because I have room heater on full blast. Note the temps before when I lived somewhere else were like 64-74F. In this room it is much warmer then that...maybe 75-80F (I need to turn the heater down because I am starting to sweat lol)

Running with CPU overclock of 140 FSB and GPU of 580 core 1450 shader and 950 memory I idle at ~44C CPU and ~50C GPU. When it is cooler in the room aka with heat off it will idle ~39C CPU and ~45C GPU.

When running F@H (same % of utilization as prime and Furmark)
I am getting 63C CPU and 76C GPU When the room is cooler I run at about 59C CPU and 72C GPU...maybe less at night when it is cold outside and heat is off. Also note the case fan is only spinning at 3350RPM as to when the temp was at 90C or higher the case fan is going 5500-6000RPM If you registry hacked the case fan you could get the temps down a good bit more.

Note I recently was running 145 FSB and it was fine for like a few days but then I started getting BSOD once a day so I turned it down to 140

EDIT: This is a post I made in NBR F@H thread. I am reducing the OC for CPU while folding during the day because of temp concerns.

Before I only folded with CPU and now added my GPU and i think the temps are too high to have both running. It is either CPU full OC and folding or a medium CPU OC with GPU folding. I dont want to burn out my CPU with doign this 24/7. Funny how my GPU was the overheating problem and now with all the mods and upgraded CPU the CPU is now the problem lol.

With CPU at 65 TDP and 260m at 580 1450 950 I am running at 72-75 CPU and 71 GPU. I might look into repositioning my cooling pad to directly blow into my case fan. I have always wanted to build a custom cooling pad but that would be a pain.



ABOUT OVERVOLTING GTX 260m ON G51j
It is not possible via vBIOS please see this forum thread for an explanation. You can do a hardware mod to overvolt but for experienced people only. (requires soldering parts on) Honestly, not worth it because the card is so old.
http://forum.techinferno.com/asus-g...a1-vbios-its-my-bios-can-someone-help-me.html

 

Wow...haha those are a lot of mods for just an old lappy. I guess it's worth it. I'm only comfortable doing repasting. Seeing other peoples huge drops in the owners lounge I was like..wow I need to do this. My temps didn't change but I guess that's mainly cause of the paste. I didn't think IC7 would be that much of a difference vs AS5

I'll give this job about 2-3 weeks to settle and if I don't see any difference, I'll order some IC7 and do it again.

 

remember as i said earlier drilling that hole from that fake vent will make a night and day difference. That is the biggest change you can make. Plus add ICD with that you really dont need to do any other mods if you don't plan on overclocking and running F@H 24/7 on it

Also you are using throttle stop too right?...to get ride of that crappy throttling?

 

Updated some more photos after i got my 920xm to work!!! I'll be adding all the info missing this week

 

those neat copper vga ram heatsinks are great but sometimes they need to be cutted in order to fit inside some notebooks. enzotech heatsinks are better, really high quality stuff, they need to be cutted too.

some more things you can do:
-use Sekisui #5760 the best thermal adesive in the world.
-sodimm ram heatspreaders
-side fans to suck the air. a couple evercool ones will do the trick.
-connect a very small fan inside the notebook. like those for northbridge.
-expresscard fan.

 

yea my notebook doesn't have like any room inside lol. What Sekisui did i use? lol

you know the difference in numbers? I'll look later tonight in ebay on which one i bought. Also you got a link to the fan that sucks air out and those heat spreaders? I used the ones i did because they were cheap. those zalman ones look awesome but 1 dollar a pop is garbage. Also they wouldn't have fit i think. Also are those northbridge fans heatsink plus fan?

 

about sekisui there are several tapes the #5760 is the best one.

about fans sucking air I was talking about this stuff:
Evercool NB-MA1 Magic Notebook Cooling Fan at Xoxide!
::EVERCOOL Thermal Co., Ltd. ::

no room inside? you sure? remove the ODD if you give it little use. you can even mod it to add more stuff like IO ports.
Mini PCI-e USB 3.0 Express Card 2 Port NEC chip | eBay
there are many ideas.

have you checked small fans? even a 15x10mm fan can make a huge difference.
Evercool 25mm X 10mm 5 Volt Fan - (EC2510M05CA) - FrozenCPU.com
there are many sizes of fans with 10mm.
those northbridge depends on what you get but imo you can't fit any northbridge cooler. it's way too big.

pcmcia fan, can be adapterd to expresscard:
Xtatix Portachill XNA-PC20 Portable Laptop Cooling Fan at TigerDirect.com

 

i wonder if a fan would help inside....i got a million holes already and I have close to 150-200 CFM blowing underneath it.

btw have you seen a power supply that has at least 3 amps and can vary its voltage? I tried one from walmart it was all the way to 12v and had 2 amps but didn't even power one fan...was total garbage

yea the express card thing wont help me. my cpu and gpu are on the otherside and i doubt that'll make a difference with everything i have done but neat idea in some cases.

Do you know of any small fans that use the internal power supply...mine is going off of external source at constant voltage right now. So my internal fan power is free

 

imo ofc if you are using a cooler it doesn't matter much if you have an internal small fan. but anyway everything helps. just like ram heatspreaders...

small fans that use internal power? none. you have to find some power source. maybe from an usb port. if you don't feel like to soldering the mobo (I never do that due to warranty issues) you can try to get the power from a mini pci-e to usb card.
this will work:


as for the power supply, just get a fan controller.

check this post it might help you:

eh i may find one i guess. You know that little itty bitty power source? Mine is open so i'll have to try to find one lol. First though i need to build a custom cooler to work better
