Without water-cooling. With the water-cooling on.
-
Under the CPU I used liquid ultra. Under the GPU I used Thermal Grizzly Hydronaut.
-
Finally my water blocks has arrived! I got 3 different water blocks by accident. But I will make it work anyway. I took the thickest one and soldered it on top of the CPU heatsink. The technique I use will I explain later.
-
Am I done? NO! I have a big big suprise coming up. When it arrives and I have installed and tested it out I will show you what I have made, Actually I have two new water cooling mods comming up. One may be a little hard to make, the order one will blow you mind. The only thing I will say, is you will be able to use the stock air cooling together with the watercooling, making it possible to still use the Alienware without the watercooling!!! The first part of the mod have already arrived, now I am just waiting for the last package.
-
The conclusion is that this watercooling increases the performance alot!!! Also the fans on the water cooler newer speeds up. The water temperatur never go past 32 degrees. Small update: I had to reposition the thermal sensor because it touched the pump. It made temperatur rise to 51 degrees even without hocking it up to my laptop. Now it measures the temperatur coming out it instead.
-
The biggest bottleneck now is the power supply. When both my gtx 980m runs at full speed the CPU throttles to 800mhz for a brief second and goes back up to 4.9 ghz again. It does not really affect the FPS. Maybe in more CPU heavy games. "Now the problem is, that the power supply cannot keep up and the performance is dropping"
-
Because a stress test isn't a realistic load on the CPU I tried overclock it even further, and test under normal load. I managed to overclock it to 4.9 ghz!!! I played Star Wars battlefront and the temperature and performance was amazing!!! "4.9 ghz stable with normal temperatures!"
-
Now here comes the fun part that all have been waiting for. The performance. I use Artic MX-4 thermal compound. It is very good, but not the best for overclocking. My room temperatur is about 23 degrees. Idle temperature Overclocked to 4.4 ghz. After 30 minuts with stress test, it never got any higher than 80 degress. That is amazing!!! Specially because I do not use any overclocking thermal paste!!!
-
My first solution didn't work out, I could not put the laptop back together. Not enough space. So I decided to make a new heatsink and connected two single pipes heatsinks into 1 heatsink. I put som rubber tube at the end of the pipes, glued it together so it would connect the two pipes. It was hard as fuck soldering every together, if I had a second chance I would have done it differently. If any one would make this mod, just buy the two piped heatsink on eBay, drill/cut the ends put something around them and glue the hell out of it to keep it from leaking.
-
I am having a 2960xm i7 Stress testing for 30 minutes with the water cooler only running at idle: Constant 4.4 GHz on all 4 cores Max temperature 84 degrees. Water temperature max 46 degrees. This is insane! I already have the three piped CPU cooler but i cannot hold 4.4 GHz for more than few seconds before it throttles.
-
While I am waiting for the water block to arrive, I have already made the processor water cooled.
-
I tested if it was working, by filling a bowl with boiling water and dumped the tubes into it. After 1 hour the fans was still running at idle. The temperature went from 26 degrees Celsius to 38 degrees Celsius. And yes I changed the water 2 times. I also tried covering the fans and when the temperature raised to 51 degrees I let it spin up to full speed and removed the cover. The temperature went to 38 degrees again fast.
-
Also I connected the thermal sensor to the main board. Instead off the outside board. It is the black wire with tape around it. I connected the sensor to the reservoir, through the same hole as the power cable for the pump.
-
This is how it should be connected. But as you can see I removed it. I made it way more simple. Now I can connect 12v power directly.
-
Modifications: To understand why I modded this device you need to understand how it is supposed to be connected. The power connection goes to the slot adapter. At the slot adapter you connect the main power and the thermal sensor. The thermal sensor should be connected to the CPU???? Stupid system I think.
-
Yes I have just bought a koolance exos-lt, and made some modifications to it. Now I am waiting for the water blocks to arrive. The shipping is very slow! Koolance exos-LT

GTX 980m not detected in my laptop MX18R2

To update the bios: I expect you to have installed alienware OSD (on screen display) and alienware command center. If not you need to do it first. 1. Open windows 2. Press FN+F7 (I/D GFX) 3. Follow the on screen instructions. 4. Now you should have disable the gtx 980m and only running on the intel graphics. 5. Download Rufus: https://rufus.akeo.ie/downloads/rufus-2.18.exe 6. Watch this video from 00:30 to 01:10 7. Now you are ready to flash the unlocked bios. I assume you downloaded the unlocked bios and have a .rar folder called m18xr2-SwicksModv2.rar Inside there is a READMEFIRST.txt Follow the steps and everything will be fine. If you have a question about one of the steps just say so and I help you. -

First, yes you can flash the unlocked bios. BUT to be sure, before you change it switch to the integrated graphics. If anything goes wrong you can always restore the bios by a blind recovery. Next, if you should upgrade your processor you should choose: I7 2920xm I7 2960xm (I have this) I7 3920xm I7 3940xm All is overclockable. -
I found this water block from a, Thermaltake CL-W0052 Tide Water. It is only 8mm thick. Maybe it could be squeezed in anyway. I found a usb drive there is 8 mm thick. Nope it can not be squeezed in. The keyboard will be bended too much.
-
Between the cover and GPU there is 5 mm
-
Now another thing I was wondering about, was the GPU memory cooler I accidentally broke off. It is just barely connected to the copper pipes, also it is made of aluminium. I was wondering how much heat the heat pipes removes from the memory. I took a working NV100w heatsink and heated up the memory cooler. Alot! The conclusion is as you see on the picture I could easily hold my hand around the heat pipes. There is almost nothing being transferred. Leaving me with new ideas.
-
Okay a quick update on a Sunday. I have been reading alot about how heat pipes are constructed how they work and if they can be faulty? I have been thinking how I could test if I broke the heat pipes when I bended them. Then it hit me! Heat it up with a candle and feel if the heat travels through the pipes. I straighten one pipe to measure the length, it is 135mm long. The two bend pipes got very hot very fast. I was happy to discover the still could transfer heat. How ever the pipe I straighten out was definitely broken. While the two pipes I bend was too hot to touch the last one was just starting to get warm. So yes a heat pipe can be faulty.
