i realize tat pmmonkey like blue color alot. eveything tat can mod definitly is blue...

I bought that from Coolice, he got it from uglyvamp.

It's not that I like blue alot, it's just for matching...
And this, is because of having extra spray.

Wah, calculator also not spared.. What's next, the whole house?

m i d only 1 here a slow bummer? or did we juz realized dat dj.eRicZzz is pmmonkey's big bro? bwahahahaaha


btw pmmonkey, izzit possible to position the si120 d other way round? d heatpipes gives better result if it is position at the bottom, instead of on top... juz a suggestion tho

i'm modding this casing too,excatly the same....hehe.....

TS,the fan not from i-cute casing meh?

Anything which I think I won't destroy in the process.

dj.eRicZzz is my lil bro.
About the si-128, I'm not very sure if the bottom position will affect the performance much since the concept of heatpipes is to conduct heat from the hotter side to the cooler side. Which means the angle doesn't affect?

Now correct me if there's another concept behind this thermal conductivity thingy in heat pipes concept. Then I'll gladly learn more.

The fan which came with my iCute casing is not LED fan. It's just a plain black 120mm fan.

There is some effect, as heatpipes conduct heat by the concept of hot fluids flow upwards, and cold fluids flow downwards-a heatpipe is basically a pipe filled with fluid. Better designed heatpipes have a wick/capillaric wall structure to minimise the effect of gravity, but the effect is still present somewhat.

As I remember, it is vacuum inside the heatpipe. Thus, I believe there wont be any serious effect.

There is fluid, either liquid or highly compressed gas. Definitely not vacumn. Search allngaps past threads for one on a heatpipe that exploded.

*coughs* Hot fluid doesn't flow upwards. That rule only applies to gaseous.
About the fluid flowing back via capilary action... if that's so, then the orientation of the heatsink really doesn't matter. Otherwise, it's best to position the heatsink whereby the heatpipes are at horizontal level.

It cannot be vacuum... because vacuum does not conduct heat.

Really? Try this.

Boil water in a clear container using a flame concentrated towards one side of the container. Put a few small pieces of paper in the water (about the size of coins). Tell me what you see.

Guess that i am wrong at that vacuum part.
But then, positioning of the heatsink will only have slight improvement/differences since heatpipes works based on capillary action.
It all depends on the heatpipe fabrication and quality. Some heatpipes just have low capillary action.

"The use of heatpipes also significantly contributes to weight reduction, since they are provided with a thermal conductivity of as high as about 10,000 W/m·K regardless
of their extremely small apparent specific gravity, i.e. approximately 2 g/cm3 for a heatpipe of 6-mm in diameter"

gaseous oso fluid.. fluid mainly divide into two.. liquid state and gaseous state.. n yeah both will flow upward if there's different in temp.. the hotter will move upward but only if in no force condition (steady state)..

So now... what I'm gonna do is... make an experiment of whether the orientation of SI-128 affects the performance. And thus, solve all the arguement. Sit quietly and wait for the results!

Cool. I'll be watching this.

no, seriously.

but... yeah make sure u get one that doesn't end up a meltdown in chloroform! I'd be interested to get one that works well with chloroform. I didn't dare try the normal plastic ones yet.

It was hard work taking out/fixing in the heatsink. Had to take out the whole mobo because the clips are so freakin hard to be pushed in.

I rotated the heatsink 180degrees so that the heatpipes are at the bottom, like what r4ydc24 suggested. And tested it for one whole week.

And what I got was:
Idle: 44
Load: 51

Before that, it was:
Idle: 45
Load: 49

A little update here on what I've done within the 1 week.
A fan controller.

The components:




Will update on the casing cover later.

Looks like in your case the accuracy of how you mounted the heatsink is a bit inconsistent. Thats a lot of variation even for the same heatpipe orientation. But I guess the point is more or less proven.

Nice work on the fan controller. Using a 78** series regulator?

New mod coming really sooooooooon.

Still collecting all the hardware, modding parts/stuffs that I need.
Planning to buy some tools... and hopefully borrow some.
( hint hint verz)
Instead of creating a new thread then abandon it for a month or so, I decided to put it here first.

Old old old, 8-year-old P3 case.


Emptied




Flattened


Hmm... not sure when I'll be able to mod this full time.
But I've already had big plans, written down ideas and drawn sketches.
Best kept unknown for I'm still dreaming about certain things.
Secret link

Concepts and plans have yet to be finalized cos I'm unsure if I can get all the things I need...
