liquid cooled heatsink mod m11xr3

heureka everybody, :thumbsup:

just want to show you my homade heatsinkmod.

the problem:

- temps gone insane high on the alienware m11xr3 i5, cpu tems were up to 94C and gpu 84-86C

the intention:

- do some liquid colled heatsink mod
- use old parts
- keep system portable and fully operational
- spend as less money as possible
- dont do serious damage to anything

thats what it looks like after 4 days workings about 4-6 hours a day.
the most useful tool was the dremel its realy a incredible tool, i loved to use
this device because of its varios options.

the results:

what ive did was took an old arktek cpu cooling block that a friend gave me because
he didnt had any use for this thing. then ive took a old heatsink from my old toshiba sa40.
the plan was to attach parts by soft soldering but testing results were horrible due too im not
really experienced in work with soft soldering. so in that case i decided to took epoxy resin.
a few days ago i orderd from ebay 2x 12V modelbuilding pump with 4mm outer aperture, 2m of 6mm outer
and 4mm inner gasoline hose, 4x 4mm to M5 muzzle, 5x tubes of heatsink plaster. then i bought from the
hardware store a 150x200x0,3x copper metal plate and a 150x200x1 brass metal plate a 6mm and a 4mm
brass pipe. unfortunatly
the 1mm copper metal plate was gone that ive seen two days ago while lurking around hardware store.

other things like tools like the dremel, cutter knife, screwdrivers, epoxy resin etc. were already available.
i was inspired doing liquid cooling mod from another german guys youtube video doing liquid cooling on his
acer laptop, what he was quiet doing very well. so after all consumption items arrived from ebay i started tear
down m11xr3 by the help of a nice youtube tutorial vid. as power source for the pump ive decided to take a
adjustable mains adapter.

after testing pump on diffrent voltages i made a gauge of the orginal heatsink by using the 1mm brass plate.
then i attached a casing for the fan made of the 0.3mm copper plate. it took a long time to make things bend things and
make everything fit. the aluminium and copper cpu block were bond to gauge with heatsink
plaster. the link betwen the two pipes where water should flow through were made off 2x 2cm brass pipes that
were attached with epoxy and final with some heatshrink tube to make sure everything is dry and clean.
the muzzels where bit problematic cause even epoxy dindnt want to fix it. the problem was i need to cut muzzels an space
to gpu connectors where really short, about a mill or so. the solution was pattex 2k stabilit express, a tip a friend gave me.
this stuff is perfect for modeling and attach smooth pieces together its just brilliant to process.

in the end i had to align the orginal casing and fill up gap from muzzels with heatsink plaster !

 

here is the rest...

 

the results:

after 10min of temps get really high up to 94C in gaming session somtimes to 96C.



this is what it look like



this is first time i powerd on m11x



temps go shortly up up to 87C when load with few prozesses.



temps stabilize after 1 to 2 min to 63-68s



with watercooling on 7-9 Volts or so (mains adapter is a little weird) -> still not on full voltage
temps get to nice constant 40-41C

 

temps on idle and low prozesses are between 58-63C

veah nothing broke

 

Wow, this takes Steampunk to a whole new level.

 

hehe your right, didnt want to win a beauty contest, its a child just a mother could love

and sorry for bad english ^^

 

LOL, that's an awesome mod. Thanks for sharing!

 

thx, np was fun to bring this up

 

some update with graphs from quick test on temps in office use/idle. need to say i took additional cooling pad like i used to do it before and not used liquid cooling.

temps rise to 70s when app is started like browser in this case and drop quckly to 60s

temps on idle, loved the last part of the graph ^^

as quick review ican tell so far, temps on gpu without using watercooling are nice and stable around 40s, think this easy to track back
on to the massiv copper thermaltake or arktec heatsink that sit right on gpu. the aluminium heatsink from the sa40 seems not to act
that persistant on temps, maybe proper copper block will be more effectiv. all in all graphs of cpu average shows nice grade, gpu is fine
and constant with tiny peaks. according to apps that have started, temps rise up to 80s and fan kicks on from average to really hard noise level (didnt pick up rpm yet). at more load it could take a few minutes to stabilize to 60-70s.

did a short test with dayZ yesterday and fps goes max to 22 fps normal to few high settings.

confirm tests with liquid cooling as far as proper liquid coolant is orderd.

if there is some time i will go on and make radiator from old desktop pc heatsink and maybe perforate
enclosure and attach an old hdd fan adapter where cpu and gpu is located...
