Currently I have two different akitio thunder 2 setups and one runs with 970 (will be referred as setup 1) and other with 1060 (will be referred as setup 2). 970 uses a more basic cabling setup and it has wire mesh paper tray cut attached. The other one has 8pin male connector replacement for the adapter socket and drilled surface. In this post I would like to do a quick comparison in between those two for cooling and performance. BTW, I am just an amateur who enjoys playing rc toys, completely have an unrelated profession and wanted to build egpu setups as a hobby. Also, I have many macbooks around me and wanted to expand their lifespans increasing their graphical design, gaming and cuda computation capabilities. I could not have gone this far without @Dschijn @Nando @goalque and @seefew s setups and descriptive posts. To start with for sure you will need Akitio thunder 2 or preferably Thunder 3 and also a graphic card. I decided to fit graphics cards in to the boxes in order to carry them around with a camera bag (cheap canon or nikon camera bags are perfect to carry akitio setups and their adapters). My must have tool kit list: 1. Dremel rotary tool (even the cheapest will do the job), dremel work station with. Proxxon and bosch also have similar tools but the key is head should be capable of holding small cutting wheels for hobby crafting. 2. Soldering station capable of at least 350 degrees Celsius (if you are going to replace akitio thunder 2's adaptor socket you would need at least 350 for sure). 3. Heat gun to wrap cable tubes 4. A multimeter to mesure 5. Glue gun 6. Welding kit (if you will cut/expand the front but still make it use the front grill) Consumables: 1. Zip ties 2. Solder wire 3. Glue gun sticks 4. 2.5mm Drill bits (at least 20 for case drilling required) 5. Dremel metal cutting wheels (at least 5) and couple grinding and polishing heads. 6. PSU cables (18 AWG or something like that) Used parts and pieces in my Akitio setups (I have no endorsements or something like that from the brands but I will just write them so you guys can found them easily): 1. Frozencpu connectright 8pin male eps 12v p8 connector ( setup 1) $2.98 2. 4pin male and female connector (to attach capacitors with fashion) $0.55 each 3. Gold plated female and male pins - 4 pack and $0.99 for male and $0.99 for female 4. Mod/smart full pin removal kit (to remove back pin connectors if you will mess the cabling) 5. Full automated ksd9700 series thermal switch to attach to front fans (I preferred 70 degrees) 6. Noctua nf9x14pwm 92 x 14mm pwm fans $21.95 x 2 (you can fit 2 of those beasts and yes they are a game changer) 7. Moddiy.com 8-Pin CPU/EPS Male Header Connector - 90% Angled - Black 1.99 USD (setup 2) you need at least two in order to get couple extra long pin legs 8. Moddiy.com Mini 4-Pin GPU to 2 x 4-Pin PWM Fan Adapter (to connect noctua fans to graphic card's pwm socket to have digital spin controls) $5.99 9. Dell 220w DA-2 Ac Power supply adater $23.99 or Corsair sf450 mini psu $89 (Dell da2 are what I prefer for my setups but for larger graphics cards sf450 is the ideal) 10. 4700mf capacitors (I used 4) $0.8 each 11. 12v swich (I used round led switch for my setup 1 and stick switch for setup 2) $0.4 12. PCI-E 8 PIN Y SPLIT TO 90 DEGREE RIGHT LOW PROFILE PCI-E 6 AND 8 PIN (you can make one by yourself or buy one from ebay) 13. Cheap 60 x15mm fans (I used two of those) $4 Cabling for setup 1, takes around 4 hours to complete (I am going to describe only the difference between other setups posted in the forum): 1. Easiest way around is expanding low profile 8pin connector's cable to somewhere around 15-20 cms in order to make an L shape starting at the top where gpu's power socket rests and take it down to the akitio's power adapter sockets. At this point you can reduce the cables to one yellow and and one black and solder those two to the back of the power socket. Image below is from my setup 2 but it represents where you should solder the yellow and the black. 2. Bend left leg of the graphics card and place a 8 pin male connector and solder each yellow and black cables to get only one of each and solder those two cables to back of the akitio 2's power socket. So in total you would solder 2 sets of cables to the back to power the graphics card and to power the akitio's card using the power coming from the 8 pin connector. If you are using a psu such as corsair sf450 you can use all 4 black and 4 yellow cables to power the board but if you will use dell da2 you should use one for the power switch and other should be blank so only 6 cables will power the card. (this step is extensively described in other posts) 3. Cut back of the two plates in a rectangular 8pin shape using dremel rotary tool and steel cutting wheel. This step just requires attention but it is very easy to do in 3 minutes. Just use a pencil to draw the shape and slowly cut the plate. (image was on top of a document so I did a quick edit) . 4.I used a round led switch for my first setup and attached it to the front of the case. To fit the switch I first created a small hole with a 2.5mm drill bit and expanded that using a round dremel rotary head. Then attached one cable to one of the 8pin connector's line's to power dell da2's switch line and grounded it to one of the 3.4v sockets as the yellow cable at the right hand side of the card. 5. Cover all cables and sockets with tubes, or hot glue gun. Cabling for setup 2 takes around 4 hours to complete: 1. Using the soldering iron remove the existing power socket of the akitio from the board. Heat it from the back legs and it will drop. 2. Organize legs of Moddiy.com 8-Pin CPU/EPS Male Header Connector in order to match the holes. I soldered and grouped legs of 2s to fit only one positive and one neutral leg. 3. Soldered two separate cable lines to the legs to power gpu and attached a Y SPLIT TO 90 DEGREE RIGHT LOW PROFILE PCI-E 6 AND 8 PIN 4. Soldered 4 capacitors to 4pin connectors via cable then attached them to other soldered pair. 5. Soldered one yellow one black cable to the board in order to power front fans and soldered ksd9700 thermal switch to the black cable. 6. Paired two front fans cables with matching cables and soldered to the yellow cable (step6) and empty black cable coming from thermal switch. 7. Cover all cables and sockets with tubes, or hot glue gun. Ventilation for setup 1 takes around 2 hours to complete: 1. Cut the exterior of the box using steel cutting wheels following rectangular shape among yellow and blue sections of the diagram 2. Cut a rectangular mesh grill from the paper holder and slide it in to the box. 3. Stick mesh grill with a epoxy or weld it in. 4. Apply black spray paint (I took it to a auto paint shop for proper painting) Ventilation for setup 2: 1. Cut the front inner side in a rectangular shape to fit to 60mm fans on top of each other. To be able to do so you should weld sides of the front sides so it does not come apart. Place two fans. 2. First hit with a sharp steel to create small holes (punches) following the diagram. Then drill thousands of 2.5mm holes using dremel work station and rotary tool. (This step took my 22 hours) 3. Clean holes with sandpaper and paint. (In the attached image I was using it with the setup 1) Post will be edited soon...
Hi everyone, I have gone through a lot of pages of this forum (related to eGPU and overclocking) and they really are very useful but not able to find anything good for my laptop. My laptop is Alienware M14Xr1 with following configurations : Intel core i7 2860QM Nvidia GT555m (3GB) 8GB primary memory 1600Mhz 750GB secondary memory 7200RPM (698.4 GB usable) 900p screen I want to use a eGPU setup in my system. Could anyone please tell me whether it is possible or not to use - In my system there are following ports available - 2xUSB3.0, 1xUSB2.0, 1xHDMI1.4, 1xMiniDisplayPort, 1xVGA, 1xEthernet1000mbps, (I think none of these will be helpful in eGPU setup ) But i have heard that if you remove your wireless card then you can plug in your eGPU there. Is it true, Please anyone share your experience with me related to this setup.
