The one in my sig, except the card was at 495/1350 during that run . I'll probably run it once more before it gets too warm out, I want to try it with one of these newer drivers .

Alright K6 here is what I am talking about.

Take this cooler:


And match it up to this box:


The cooler sucks air in the top and pushes it out the front I already have the cooler but alot of the air is blown out the sides of the laptop because it has nothing to channel it to the vents in the bottom even though its not direct it still drops the temps 5~7 degrees C I just want it cooler and this is what I came up with still havn't put it together.

Hmm... that's what I thought you were talking about, but let me just make sure. You have this plexiglass triangular box that fits like a wedge under the laptop to prop it up. The three holes on the top of it correspond to the CPU fan, GPU fan, and memory vents. In the back is that cooler (pacific breeze, yes?) that pumps air into the box. Here's what I'm saying. I'm betting that that cooler pumps in much more air than the two laptop fans pump into the laptop, and therefore you will have positive pressure within the box. This will push some air into the memory vents, but, in the end, the air will start to accumulate and only be forced out through the cracks. The air will therefore become stagnant and the hot air will again accumulate, bringing you back to square one. Of course, this is just my hypothesis, you're welcome to test it as I very will could be wrong. Also note that the cooler draws in air from the top, which is where your laptop exhausts its hot air, so that cooler isn't a very good design to use with our laptops anyway. However, you could try another design that props the laptop up in the back and creates a wall between the back of the laptop and the bottom. Then you could put that cooler on the CPU side of the laptop and it could blow sideways clear underneath the laptop. That's something to think about . Anyway, I like your concepts, keep at it

Clean/Cooler air conducting Cooler for GEN2

Here's my cooling project that i've completed awhile ago.

The objective of the project was to create a way to throw cooler air directly into the 4 vents on the base of the GEN2 (namely, 2 active vents on the side and 2passive RAM vent). So I found an old heavy duty monitor stand (get them for $10.00 on ebay). They're perfect for the project because they're designed form a plastic mold allowing one to create hollow air passages leading up the the top. Basically, after cutting up the stand, I glued a ventec 2 fan Cooler to the bottom so that air that COOLER and CLEANER air circulating under the stand is thrown up into the 4 vents. COOLER because the fans are taking air from the freely passing cooler air that's flowing below the cooler and isolated from the HOT GEN2 (sitting on the desk normally warmer air that's trapped btw the GEN2 and desk keeps being blow up). CLEANER because I open my GEN2once in 3 months to find the 2 copper fins almost dust free. I found that most of the dust comes from the desk surface (which is not far away from the fans). I've also added dust guards (mesh) over the fans which catch most of the crud (which I blow away compressed air once a month).


Now for the tour:

Here's th top view of the cooler. The 4 holes are correspond exactly to the open vents. The 2 round holes cool the RAM


-----------

Here's the underside of the cooler. It has two giant fans. Notice the plastic sheets on the sides covered up the holes. The fans can be seen from the 2 RAM vents on the tops, so they're throwning some air directly upwards to cool the RAMS. Then leading to the side and then back along the edges (there is a cavity, you can't see) air is shunted to the 2 intake vents on the GEN2.

------------------
I liked the results so much that I was planning to make one for the XPS1 (my other lappy). So here's an fresh underside (without any work done to it) showing the airflow using a diagram.


----------------
Here's the cooler toggles showing from the back.

--------------
And a different view from the back and under. The cooler came with a notch to adjust fans speeds or a switch to turn it off. Plus I get a 4 USB slots. The fans can be USB driven, but I normally like running it with the provided Vactec adapter (since it runs a full power).


------------

I've also sealed the vents with window sealing foam (the black things around the vents) so that minimal air escapes from being sucked up by the "inhaling" GEN2.

And there's the baby cooling herself off......



My idle temps are 32 for the CPU and 42 for the GPU. I've not removed any services (48 running) and 33 processes started so the CPU Is busy but cooler.

Ahhh, yes, very nice nkhan , I've seen that before. How is it for typing and daily usuage? Also, do the fans push enough airflow into the side vents so that the fans in the laptop dont have to suck air through the cooler?

The intakes sit inside my exhaust vents and just running by its self with out the boxs it cools the laptop good to Test it last night I put tap around my laptop sealing it to the desk. I got another 2~4 degrees C doing this so I am assuming that by forcing the air into the laptop instead of just blowing it across the bottom it should cool it better.

If it works then go for it. I was only hypothesizing; the only real way to tell is to do it, and it seems to work so far .

K6, I read your facinating post about the custom cooler you made (with the two fans cooling the Gen2) and was inspired to venture on a water cooled laptop project (just for fun, and I'm not going to argue it's practicability as it defeats the purpose of mobile system).

My XPS Gen1 sits like a fat fart all the time on my desktop, so mobile has never been an issue since I plopped the sucker on my desk (2 years ago). I've got two options for cooling this laptop. Actually, I'll try the easiest first (1) then the more challenging on (2):

OPTION 1) I'm going to connect an Aquarius II Water cooling system to cool the CPU (its' a 3.4 P4 PressY). The GPU (9800M with successfully 16 pipelines opened) is also Shimmed up (with a mod that I've explained here, you can see the temps a low, however, at the cost of added noise from the fans.


Look for nkhan:
http://www.notebookforums.com/showth...=130091&page=4


Well, overall temps are much lower fans need to keep blowing to keep temps to 52 (CPU) and 52 (GPU) on idle. The culprit is, of course, the Prescott CPU which can easily idle at 62 (if I turn fans to slow). Yes, I could change the Prescot for a NorthWood; but that's not so much fun as water cooling.

So, I've got a hold of a couple of .43" inch (1.1 mm) thick Water blocks that might just fit (with a little modding). Koolance makes some really thin ones.

I purchased an extra XPS HS Assembly (with double fine to cool the CPU and and a chamber which runs FAN 3's air out the back). I think (not sure) that with a little imagination I can mod the HS to accept a Waterblock on top (ALONG with the Heatsink/fins assembly still intact. This should hopefully result in a cooler running XPS as a cooler CPU will mean fans slow or off most of the time.

For those who don't have the XPS Gen1, this lappy is quite thick and thus has room for a lot of imagination. It has a huge Battery compartment and 3 monster fans (which can all me replace with a little inguenuity with either one of these.

--A Waterblock without obstructing the Keyboard.
--A Freeon Air COmpressor chamber
--A larger fan with radiator
--A peltier project Tijgert at Notebookforum is at this one).


As for the Water Pump (the Aquious 2 pump just might fit in the battery compartment along with the radiator. They won't fit completely because they'll stand up while the top half's of the pump and radiator will fill the space left by the battery. The bottom half will be sitting in a cavity of a customised Cooler stand (I've already made one with with fans for my Gen2 laptop. see link below)

http://www.notebookforums.com/showth...80#post1841380

Since it's raised, all I need to do is cut whole in the right bottom side fo the cooler for the PUMP/RADIATOR assembly (to sit). Fans in the cooler will be made to blow cool air from under the cooler into the compartment thus adding to a cooler system.



If (1) is successful then, I'll attach OPTION 2:

(2)I'll attach the waterblock to an External EXOS-1 Koolance Cooling system which I just won on Ebay for $175.00.

I'm searching for an alternate current source to run the 12v water cooling systems (as the USB give 5v only). I'll probably need one adatper 12 Volt (5 amp) to run the pump and 2 fans (2 in cooler and 1 attached to the Radaitor). Anyone, good at electricity. What voltage (amps) do I need to run the following (see (a to d):

Two fans in the Cooler (both adjustable and depending on how successfully the waterblock cools, probably remain off most of the time):

(a) Thermaltake 12V Smart fan (blowing air up into the vent of FAN ONE (GPU Fan on left))
(b) Thermaltake 12V XBlower fan (blowing air into the cavity where the aquious II pump and radiator sit)

And the 3rd fan on the radiator:
(c) 80 mm Thermaltake 12V Smart Fan (will replace the slower Fan that comes with the Aquarius II radiator)
And of course the :

(d) 1 Aquarius II Pump


Let me know if you got any better ideas or suggestion?

eh, i used it and thought it was pretty junky, too slow to heat up, bad for fine work, and trying to unsolder stuff with it needs at least 3 hands.

their commercial is ridiculous too, they greatly exaggerate the time required to cool. I'll take a regular soldering iron anyday, cord and all, but to each his own.

Then you used it wrong, it heats up in ~0.1sec and cools in at most 4 seconds.

nkhan, I'll take a look at the XPS1 service manual and see what I can do. Btw, your links dont work, I think you included the ellipses (...) in the url.

K6, Think the first link works now.

Ok, for those still wondering if I was really serious (though, i agree that the idea of water cooling a laptop is laughable), here's the picture (below) of the Heatsink. But one may argue that the XPS (Gen 1) is more like a compact Desktop (that sits flat and comes with an attached monitor and a a heater that's sufficient to warm a one room apartment).



If you've actually seen one of these cpu heatsinks of the original XPS, you'll find (that if you remove a metal cover - not shown) there is a block fins (also removed) about 1 cm high where you now see the rectangular copper shim (see pic above). I had to use the oven to heat/loosen the fins and then weld the thin copper shim (on which I've placed (not attached, yet) the water block.

The whole process of melting it all together involves the use of multiple C-Clamps and preferably some metal bars and flat-nose vise grips. It's important to make sure that the pre-welded pieces don't fall apart when heating (so the the clamps/grips are indispensible tools).


Once you remove the fins (they'll come off intact, so you can use them elsewhere) underneath you'll find the 2 copper pipes. The copper shim should be applied and then a flat (2 inch wide) supporting bar should be place on top of the shim. After that, I used 2 medium sized C-Clamps to apply equal pressure on the bar so that the copper shim melts down onto the base (and at the same time squashes the 2 copper pipes so they flatten and make room for the shim to sit flat). The pipe are very soft and can be flattened under pressure (esp when hot). While applying heat, I kept tightening the clamps (caution: use gloves) so that the copper shim is snuggly sitting on the heatsink's base.


Give it about 1/2 hour of heat (while all clamps are on) to weld together and then let cool. The copper will loose it's color (that's a good indication that it's hot, so don't touch it).


I've (just) placed a Koolance CHC-A05 water block on top. Notes it's 2 pipes are sticking up a bit and might (hinder the keyboard) so I'm expecting another (flatter) block soon in the mail. I could alway dremel the a part of pipes since they're almost an inch long.


Once i remove the fins, I've got a space of 2.5 X 2.25 X 0.80 inches for a water block. Let me know if anybody knows a good waterblock to fit the area?

This is just the beginning. I'm still waiting for the Aquious II water cooling kit to come.

I haven't thought about how to hold the block down, cause I've not finalized on the type of block to use. But there is cover that fits on top of the heatsink in such a way to direct air from the 3rd XPS fan to the back.

If I can somehow (keep the cover on top), I'll have an AIR plus WATER COOLED XPS. The 3rd fan will help cool the waterblock from the outside though, and I'm not sure how effective that'll be.


If you have any suggestions, please let me know?

Wow, nice work nkhan! I guess my only question would be did you make sure that there is a metal on metal connection (solder or welding) between the heatpipe and that copper shim? I guess I dont full understand the process/design.

K6, there's no AS5 in there at all. And yes, that shim is really welded well onto the heatsink base. Basically, now the two copper pipes (leading out to the fins) are sandwitched between Dell"s original square shim (which sits on the CPU) and my rectangular shim on top (that you can see).

Btw, I managed to alter the angle of the 2 pipes sticking out of the waterblock by heating and hammering it down. So now it should fit in the laptop with the keyboard in place.

I'm thinking making my own waterblock that will actually use the copper shim as it's base. Will require a welding torch and that way I'll be able to make a wider block that will cool more surface (then the one you see in the pic).

K6, I'm curious to know what to put between the waterblock on the shim. Should I use AS5 or is there something better? I also have thermal pads (shinestu once- if I remember what they're called).

Let me know what you couldn't understand. Sorry, I've not got pics of the original 'unmodded' heatsink
