AIO cleaing …
We have tried to do the cleaning with tools which are already in the household or can be purchased quickly and affordably in the shop around the corner in order to make it easier for you to follow up.
After everything lays disassembled in front of us, we take a small brush and clean all parts of the cooler / pump unit under tap water. For example, you can simply buy a cheap toothbrush from the discounter.
The radiator connections can be cleaned as far as the brush reaches, but the radiator would not become clean from the inside.
Therefore, we have chosen a simple solution in which the pump helps us: in a provisional-cut hose we push a small piece of the rough side of a sponge.
The sponge catches impurities as soon as the coolant circulates. In addition, we fill the AIO with a solution of citric acid, which is normally used for de-calcifying.
The cleaning setup looks a bit adventurous, but since the cleaning of the water cooling will take only a few hours, this does not disturb us further.
After about 2 hours we were curious about the result and guess what, it was a complete success!
We then reassemble the AIO water cooling and of course fill this time with corrosion-protection coolant instead of citric acid 😉
Here is a detail of our method fixing the springs:
The result …
We tested the AIO water cooling again with a 12V power supply. Alternatively you can of course use also an old PC power supply with a small load and then connect two special pins, in order to start the PC power supply. In our forum you can see the PSU Pinout to start a PC power supply.
The result of the AIO maintenance is awesome, the pump sounds much more silent and more even than before. What remains is the low buzzing noise which is typical for AIO water cooling.
Here is again the sound of the AIO before the maintenance:
Here is a sound of the AIO after the maintenance:
In addition we would like to improve the AIO now a little bit 😉
