Improving P150HM GPU and CPU fan cooling performance (instaling 2 extra fans)!!!!!

carton

mb later, it is just a prototyp to find out if all works like i want it to work)

 

Heh, so with the raised fans you have some ramsinks under those?

 

im so close to finishing my big 3d printer, i will be able to basically print a whole new case for my p150hm, and one of the things i hope to improve is the cooling, i plan on upgrading the whole cooling mechanism for improved airflow, and increased strength on the screen and better ergonomics, like rounding the front edge where your hand gets cut when typing. then im going to upgrade the crap speakers and sub woofer. i also plan on making a piece to fit in the battery slot while im at home, maybe it will have some fans in it or something, that would be a good use of the space. also i plan to integrate some flip out feet to prop the back of the laptop up with for extra airflow.

btw i did this hole thing with adding some fans a while back, but i couldnt find any thin enough to fit on the gpu, so i had planned on printing a little air duct to shoot some extra air but i never got around to it. btw when i did my mod in the summer in az with a room temp of 30c i was overclocked running bf3 at 53c haha it was amazing and loud.

 

@aduy

When your 3d printer is done, would you sell its services? Like if someone made something in CAD, or what ever program you use for that would you sell its services to people? I think it'd be cool to be able to make new cosmetic items for a laptop.

 

If you wanted to test out a few designs while waiting for the printer, I have a Makerbot Replicator 2X that we're always looking to put to use. I'd be willing to try some things out for ya if you shoot me over some files.

 

Best off having the fans on the outside of the case and ramsinks on the GPU otherwise the flat surface of the heatsink wont offer much.

 

i am finaly ready with my mod, here the result:





MSI Combuster (15 min)

before:
max gpu temp.: 92° C

after:
max gpu temp.: 76° C


max gpu temp (OC 1040/1350): 88° C



3DMark run (Fire Strike)

before:
max gpu temp.: 70° C
max cpu temp.: 77° C

after:
max gpu temp.: 60° C
max cpu temp.: 76° C


Aion Online (1 hour)

before:
max gpu temp.: 81° C

after:
max gpu temp.: 66° C

 

haha nice work buddy, its fans galore!

Nice mate - Sounds like it is working

But - can you explain how the Fans are connected or where the Fans are connected to get their working power? In your picture is a small red USB like Interface is this correct?

Maybe it is possible that you Write me a pm in german also?

 

Looks like you might now be feeding the CPU fan your hot air.... You might want to add some vents on the edge in the middle.

 

powered and controlled via my CM Storm cooler.

yes you are right, i need much more vents...

 

Hehe nice, thank you..

3PIN Molex Splitter => 1,79 EUR


3 PIN Molex to USB Adapter => 1,79 EUR


And then 2 of these fans each 2,97 EUR:

Seems legit.. ;>

Idea:

By using smaller fans like 60x60x10mm

install 4 copper heatsinks extra on CPU and GPU, then cut 2 holes for the fans in the backplate, the wires of the adapter should fit through the inside and then install it like you have done it with your 3 PIN Adapter. Can connect the USB Adapter then to my Zalman N3000 ;>

The fans can be exactly fitted to the holes by using hot glue - then it is also possible to use dust filters and protective grilles and the notebook is almost mobile and can be used on a desk also

 

thanks, but i already have a 3d printer, im just designing a bigger and better one, you know printerception. also the 2x is probably too small to make the size of parts that i plan on making.

 

I think youre CPU cooler is too small that's why you don't see too much improvement.
Anyway those fans are 5v or 12v?And what RPM's are?
BTW very nice and clean mod!!!!Good job!!!!!!!!!!

 

It's the air pathing that we discussed, you don't get that problem with no back cover.

 

GPU: 60x60x10, 12v., 4500 RPM
CPU: 40x40x10, 12v., 5000 RPM

may be its is realy to small, but im to laizy to change it now


here version 2.0 of my mod:
- added more vents
- closed some gaps to prevent hot air flow to other parts of notebook and from gpu to cpu
- build new booster





MSI Combuster (15 min)

76° C => 74° C




3DMark

GPU temp: unchanged
CPU temp: 76° C => 73° C

Intel XTU (CPU stress test, 10 min)

mod off: max cpu temp. 86° C
mod on: max cpu temp. 82° C

 

Hm, maybe you could make the foil mod to improve the airflow through the copper fins of the heatsink - temps should go down with the mod.

 

1.You are using very slow fans.
2.you are using 12v fans from 5v USB ?!?So running them with only 5v,they are not running the full potential of youre fans.(12v =5000rpm.5v=1000-1600rpm:confused2 and on the top of that youre CPU fan is small.
Try to find 5v fans trust me you going to see huge difference :wink:

 

Just be aware that the power draw will go up to if you are feeding it off the mobo.

 

fans with more rpm will cause to much noise

normaly I use 12v power supply from my cm storm cooler (i can control the fan speed with it also), usb ist for the mobile use

ps: this mod don't really works like i wanted: the hot air don't leave the notebook completely, i'm now looking for solution of this problem.
