Having just done an upgrade from AM4 to AM5, I have started to feel this pain. A simple mobo, RAM and CPU swap is turned into a 5-6 hour ordeal. Getting the heavy arse rig on the operating table; drain the loop; flush the loop; clean everything up; remove old components; install new components.
New components' socket isn't in the same spot... Curse repeatedly at how much longer this is now going to take. You've got it all in now and don't want something DOA. Cart the rig back to your desk for a test POST because you don't want to build and fill the whole loop only to have to remove and drain it again.
The new components are all good. You tell the missus that nothing is DOA and you can finish the job. "You're still not finished?" She remarks. She knows nothing of your pain. Cry deeply inside.
Migrate the rig back to the operating table. Time to make two new tubes from a limited amount of leftover tubing giving you a handful of goes at the perfect bend despite having not done it in 4 years. Totally **** the first bend (call it a warm up). Nail the second and third bends, cut the tubes down to approximate size. Measure them accurately and cut to size. Ream the ends; test fit; prepare to cheer or cry as the moment approaches. Clench your arse cheeks as you force fittings onto the tubing you have so expertly crafted. The moment of truth. Push in place and tighten down... Success. They fit perfectly. Enjoy this small victory by having a drink and loosening your sphincters.
Fill the pump, activate the pump, stop pump. This is now the mantra of your life. Rinse and repeat over and until she stops gargling. Pick up your stupid heavy, filled with water rig, give it a tilt and shake. She gargles some more. Question all of your life's choices whilst you're shaking a 20kg computer around like an orangutan with a big rock. Cry deeply inside again, but this time, harrowingly weep to the sounds of the air bubbles escaping your apparatus of plastic and silicon. Put the heavy thing down.
"I should leak test this for 12-24 hours." You don't have the time for that crap; you've got other things to do. Tell yourself you're a fool for still having a loop in 2024 - you could've easily done this on air by now, eaten dinner, and watched at least 5 episodes of Taskmaster. Sell all of this junk to some other computer alchemy practitioner living in the ways of old. Buy an AIO like everyone else on the Internet and say ZeRO mAiNTeNaNce to yourself repeatedly. Continue to question what you have become and why you are still doing this to yourself. Nonetheless, you're in too deep now.
Run it for 5 minutes. No leaks. "If it's going to leak, it would've leaked already!" Move the stupid heavy, filled with water rig upstairs back to your desk. Power her on and plug in your army of peripherals loathingly.
Start messing around with BIOS settings and getting the lowest fan curve known only to the secret society of custom water loops in 2024. Bask in this long forgotten knowledge of old times that you are privy to. Listen to the sweet nothings of silence serenading you as your fans don't even turn. Was it worth it?
It always is.
