This one was a challenge!
A 6 year old AMD 3990x Threadripper system came in for what was supposed to be a simple pump replacement after it stopped working. But once I opened it up, it was clear this was anything but routine. Coolant had leaked throughout the system, and the fluid had degraded badly.
By the end of the process, it went from a soggy mess to a like new system (filters included).
What happened:
Oddly enough, the system initially passed pressure testing⦠until I moved the hoses. Thatās when the real issue showed itself, 2 out of 3 EKWB 45° rotary fittings began leaking under movement.
At that point, the job turned into a full teardown, deep cleaning, rebuild, and retest, with a new pump and fittings.
The entire loop was disassembled:
⢠Block and pump housing were taken apart and cleaned
⢠Radiator and fittings were flushed using specialized fluids
The setback:
We did lose 4 out of 8 RAM sticks in the process.
They were thoroughly cleaned with electrical cleaner and air dried for about 3 days, but itās likely coolant was retained in the heatsinks. This also made troubleshooting more time consuming since isolating the working modules is a little slow with 8 sticks.
Final outcome:
The client opted to move forward with 128GB of RAM, with the option to expand later if needed.
After a BIOS update and full system stress testing, the system was shipped back in like-new condition. I decided to stick to my original labor charge despite this curveball.
