Cleaning The Sh!t out of My Water Cooled PC

Scroll this

Arctic Panther, my custom water cooled gaming PC that has been built and re-built over the years, is clogged with residue — so it’s time to clean it out!

  1. Why use a dye in the liquid if you get gunk other than make it cool to see

  2. maybe you should of re assembled the blocks and put them in the cleaning loop.

  3. Micro-center USED to be a good place to get cheap computer stuff. Now they're MORE EXPENSIVE than Best Buy. The only thing they can offer is convenience. If you want good parts for cheap and can wait, order online. The markup at the store isn't worth it. Love the ApeVape shirt though.

  4. Paul… a lot of time not to just have completed the entire flush; using step 1.

  5. Hey Paul, in the video it looks like you spilled fluid on the Gamer's Nexus Mod Mat. It also looks like that fluid was potentially Phosphoric acid. If that was the case, how well did the mat hold up to the fluid?

  6. Phosphoric acid is the stuff in cola. Diluted down I wouldn't be super worried about getting it on you. At 90% or something though I'd be careful with it.

  7. pro tipp: use a electronic toothbrush (ultrasonic like pulsonic) for cleaning 😉

  8. So many people commenting about "glad I went with air/AIO" like they ever would have gone with a custom loop anyway. It's not about convenience, that's not how hobbies work. Some of us enjoy building more than gaming, too.

  9. Great video as always. Anyone figure out the name of the ambient song in the background?


  11. 10:00 We went from PC and tech stuff to trying to bring alive some kind of creature built of random people corpses

  12. while paul was looking like was gonna do some breaking bad cooking dogie takes nice nap without a care aww cute pupper and s/o right hand man joe

  13. 10:47 One of the last PC Power & Cooling PSU's…

    I'm still using mine from 10 years ago.

  14. Paul Next time please show us the performance difference before and after cleaning the sh!t out of your pc…

  15. Mayhems: "it has been developed to clean you (sic) radiator's (sic)" = lol

  16. Yet another video showing why PrimoChill's Vue is not worth the effort unless it's purely in a show PC that's only run a couple hours a day.

  17. OR dont use fucking any type of colouring because this is the mess you will be faced with no matter what lies the manufacturer fill your stupid head with

  18. How do you keep the o-rings on the monoblock from popping out or their recess during re-assembly?

  19. O-Ring + knife = leak. If not now, later. It’s always best to get new seals. They’re cheap.

  20. And that is why you use the stopper in the sink if you are working with tiny stuff like that.

  21. Hiro doesn't look in the least bit bothered by not having protective gear on.. just dog bed.
