Watercooling for eGPU?

Recommended Posts

Hello Tech Inferno eGPU community.

Just doing some research and wanted to know how many people here implement watercooling into their eGPU rigs.

Reply below if you do or you don't and why! If you do, what enclosure do you use?

I don't think I've seen a water cooler egpu guide posted here yet but if someone did one and documented their build log I'd love to promote it to the front page as a featured article.

There are a few obstacles to watercooling an eGPU:


1) Quite a few people want a compact setup (as evidenced by the modded Akitio Thunder2 boxes and mITX GTX970s or lesser cards), which is defeated by the addition of a radiator. If someone makes an eGPU setup in a case based off a mITX case then space is less of an issue and a 120/140/240mm rad can be easily installed (depending on case). That way an all-in-one watercooled card can be easily used, or a custom loop built.

2) eGPUs are already rather expensive. Adding a water block, pump and rad on top of this (or splurging for a card watercooled out of the box) makes an expensive project even more expensive.

3) People who opt for eGPUs typically wish to improve the performance of their existing laptops, or like the portability of a laptop for their main rig, while having a more powerful graphics in a "dock" of sorts. This isn't the typical high-end enthusiast, who would probably opt for a desktop to start with. We're happy with not-quite-desktop performance levels which are none the less usable, as opposed to seeking the bleeding edge (although, as always, exceptions exist).


As to how I'd do it: I'd grab a small mITX case, stick in a 240mm rad, the PCB from the Akitio Thunder2 or the Rocketstor, a PCIe riser to the card and an ATX PSU. The PSU powers the pump, card, Thunderbolt PCB and whatever else I'd stick in there. It isn't complicated, just expensive, and in my opinion rather pointless.

I don't see why you can't have a watercooled eGPU if it's some kind of non-reference card where the manufacturer has all-in-one watercooling as standard on that card, and the pump is built-in (http://www.corsair.com/en-us/landing/hydrogfx).


As for the fan, you could probably just have it directly connected to a 12V or 5V rail on the PSU. Perhaps add in a potentiometer to adjust its RPM.


I'd happily do this if I had an AIO watercooled card, so if anyone wants to send me one, my address is [censored].

My latest eGPU was a EVGA GTX 980Ti Hybrid running in a Cooler Master Elite 130, worked great and had awesome temps.

Even installed a fan speed controller in the 5,25" bay and reduced the speed/noise of the pump and let the fan on the radiator spin slowly.

It seems that it's pretty common to mod a CPU liquid cooler onto a GFX card: http://www.overclock.net/t/1203528/official-nvidia-gpu-mod-club-aka-the-mod




As it is, under Furmark at 1.050V (-0.025V from factory voltage) and 810 MHz core clock (+13MHz from factory clock), my GTX 580 SC runs at 87C, 85% fan speed (I use a custom fan curve), ambient temp 30C. It runs stable at 888MHz core clock (+91MHz) at stock voltage, but I don't run it at that setting for fear of overcheating.


I could definitely get a higher overclock tho, again, if not for fear of overheating.


I would love to try this out on my 580... If I weren't such a cheap prick who doesn't want to pay even $50 for a used liquid cooler.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      The GPU works, The PSU works, The system works. [individually they all do work]
      The system works perfectly fine without the WLAN card.
      When i put the system to sleep and hotswap the mPCIe riser and WLAN press something on the keyboard.. Restarts.
      Will shutdown in roughly 27 seconds for those 27 seconds it works just fine like how it normally would on external monitor.
      When i shut it down and plug the riser and switch it on, same story. 27 seconds.
      I don't even see a error. I get to login screen directly. I used DDU already.
      I timed it. no matter what i do if i use the eGPU, External monitor it restarts instead of pause-play. I have 27 seconds.
      Need help!

      I got the exp gdc beast 8.5 got all the connections right... laptop boots up... fans turn on the gpu.... device manager detects gtx 1060 with a “ ! “ in a yellow triangle. Now what to do.... i tried to do the bios mod.... but realised that i have 3.07 version. 
      1 is there any way to get this done without the mod?? 
      2 if mod is the only way... kindly help me with step by step instruction in laymans terms... i m not a techy... so i might not understand technical terms.... altho i am interested... but learning yet. Please help.

      Has any company out there launched a laptop with an external MXM port? 
      Just curious since with the boom in the gaming laptop market and some companies launching eGPU thunderbolt enclosures, isnt the MXM faster?
      Is it because of licensing issues? or hardware problems?

      Hello guys ...

      i wanna make sure that everything is going to work fine with my laptop so i got some questions

      First of all my laptop is Lenovo Z51-70
      CPU: I5-5200U 2.2ghz
      iGPU Intel HD 5500
      dGPU:AMD R9 M375
      Ram: 8GB (will raise it to 16GB)
      HDD: 1TB stock one
      SSD: 120GB (for my games and windows only)

      now i investigated  a little about eGPUs and found that i need a M.2 or thunderbolt, i've found that my wifi card use a M.2 a/e key aka ngff, so i will be using the GDC Beast NGFF version

      to the bad part / question part

      What do i need to know other than the stuff above?
      what is the white-listing thing? i found on support forums that my laptop support some wifi cards only and it's bios cann't be modified according to bios modifying forums (not here)
      in same time saw some posts on reddit that says if ur bios have UMA graphic option then you will need to disable PAX / WIRELESS and enable UMA and it will work fine, the question is that true?

      i wasn't able to find anyone who did it on Z51-70 i found only 1 post on reddit for Z41-70 (which after research found that both are using same M.2 a/e key slot and also same bios... but the one who posted only replied that it's recognized with some errors and never replied back with any updates so still not sure about it.....
