Dirty water block?

[Pikatchu]

I have a Corsair CPU block for my AMD CPU.

 

Recently, I have notice air bubbles building up from my custom loop. The inlet side of the block is clear and bubble free, but the outlet side have air bubble escaping. As time goes, more and more bubble appear.

 

Is this due to a dirty block? Do I need to just flush the block? Or I have to dissemble the block and clean it?

just take and rotate your case around a bit to dislodge those air bubbles. You can also slow your pump down as well, this can help as well.

It has been running bubble free for the pass 3-4months, just recently it started to have bubbles again. No fluid changes or flushes for few months.

You could have a hairline crack in the block or fittings that lets air in but won’t leak water.

I have found some time to drain the loop, then changed the fitting.

It seems like outport of the CPU block is still generating air bubbles.

 

I will probably buy a new block and see the results, thanks!
