Internal leak

What constitutes an internal leak? It occurs when coolant seeps between the channels in the water block while remaining within the main O-ring. This is often triggered by temperature fluctuations causing the Plexi to expand and contract and since most of our blocks do not use seals between the channels, the coolant can seep in the space between the Coldplate and Top Plexi, although this doesn't impact the water block's performance, it may lead to slight discoloration on the cold plate.

If you've encountered this with your water block you can follow the steps below to try to fix the internal leak, but please note that this may not prevent the internal leak from happening again in the future.

1. Confirm the Visual Nature of the Internal Leak:

• Ensure that the leak is indeed internal and is not going past the main O-ring.

2. Inspect Fitment of Plexi Top and Bottom piece (cold plate):

• Check that the top screws that hold the Plexi top on your water block are not loose, if any of them are, retighten them to 0.6NM.

3. Dissasamble and clean the block:

• Make sure there are no visible defects or irregularities in the Plexi or the coldplate that could affect the fitment.
• Clean any discoloration on the coldplate or the Plexi, you can use the steps in the following How-To video
• If you disassembled the water block make sure that you reassembled it correctly, you can find the picture of the assembly for most currently available blocks in the installation manual.

Implementing the mentioned steps can, in certain instances, reduce the likelihood of future internal leaks. However, it's essential to note that this approach does not offer a 100% guarantee for all water blocks, as some may remain more susceptible to internal leaks than others.
