Would like guidance...

I have a Toshiba Qosmio X305-Q701. I have upgraded the processor and installed a secondary fan, it was always my plan to put liquid cooling in this beast. Anyone with experience in laptop modding or liquid cooling for notebooks, I would appreciate your guidance in this matter(parts, sizes, and efficiency).

 

Liquid cooling for laptops is a big NO. Because there is no space inside.

 

I think you will find otherwise on mine. I have measured a space inside of 6 inches wide, 3/4 inches high, and 7 inches length, inside mine. if I took out the two heatsinks and the two fans, that almost doubles. So there is that potential space there. By the way, I asked for guidance on parts, not someone to tell me that it cant be done. The same was said about my fan mod, and now I am able to overclock further than anyone else with my model, and do it safely. So now with the success of my first mod, it's on to the next step.

 

actually it may be possible.
Its going to take a lot of modding/warranty voiding.

You should look at probably 1/4" to at most 3/8" tubing for the circuit.
Usually cpu waterblocks are big, you may want to try using northbridge or gpu waterblocks instead.
Mounting them may be hard, so you may have to build a custom mounting plate.
As far as a pump, it would probably have to be external. I am not a water cooling guru, but from what I see, most water cooling pumps are large.
The smallest i have seen is in the NorthQ 3590.

You may want to check it out.
Danger Den has awesome stuff, as does EK, but finding something which will match and fit is the real challenge.

A CPU water block is going to be significantly thicker than a normal heat sink (you’ll need special mounts, and a custom block) + then you need a lot of space for the radiator, what about the pump ? not to mention all the tubes, clamps etc... Good luck fitting all that in to a notebook.

Water cooling a notebook is not impossible, actually I can remember reading about a company designing a water cooling system, but IMO doing a custom mod at this point is almost impossible, unless of cause you want it to make it like a desktop (have all the parts outside the notebook).

 

The radiator and pump will be the hardest things to fit, then you'll probably need a water tank of some sort, as you don't want a too small amount of water going around and around making it heating up too fast, as i think you want a watercooling-system that is very effective.

I'd say it's doable, but i'd say it wont have so much portability/mobility after the mod is done


Use the waterblocks you could find that seems to fit fairly good with your original mounting holes and size of dies. Then the smallest possible connections.
There should also be some sort of minimal waterpump that should be enough for that size.

 

maybe you could do something more hybridized.
Instead of using a full blown water cooling system, maybe have some way of installing a hollow copper cube atop the cpu. If that cube was filled with say 2 table spoons of water, that would drop temperatures quite significantly, even without a pump.

You would still have the standard heatsinks, but in addition, small reservoirs of water. It could work, since water has such a high specific heat.

Really ? Water has a high heat capacity, but very low heat conductivity. Therefore I don’t understand how having a small amount of still water on top of a heat sink can be a good thing. Sure, for the first few minutes it may seem to perform better, but after a while I think it will only trap heat and reduce the heat transfer across it. I could be wrong here, but do you know any such hybrid cooling device that use only a tiny bit of water ? A tablespoon or two can only hold a very small amount of heat.

 

How bout stuffing desktop cards and mainboards into the notebook. Would be fun for you if it worked out.

Heat pipes will work better, IMO.

 

Wouldnt it be though. I mean, thats where mobile computers are headed anyways.

 

I can't see it, but I might be wrong again!

 

I don’t think laptops will be getting watercooling units anytime soon; I mean these days all new technology is pointing to cooler and energy efficient chips.

While Apple is trying to patent an old idea, seems like guys from NEC has already built one 5 years ago.

 

Yeah I saw that about a year ago, too bad that it never became standardaized. By the way, I've been researching, and apparently I dont need a radiator, since its such a small daisy chain. Also Coolermaster is set to release a whole new line of low profile liquid cooling accessories. So I'm still searching and researching, but the Cooler Master gear looks promising. When I'm done, I will post screens, in order to benefit the enthusiast community.

 

In the meantime, I'd like to just give a big thanks to everyone who contributed.

 

So minus the fans and heatsinks I have measured 6 inches back to front, 1.8 inches top to bottom, and eight inches wide, of free space for an internal solution. Or 8"(Width) x 6"(Length) x 1.8"(Height). I am already shopping for parts to try. Ambitious? Yes. Impossible? Not at all. Here are the parts. If all the specifications are correct, then I still have room, for the gpu block. There is a hole in the MB underneath the GPU where the fan takes in air from the bottom of the laptop.
