Weird Clicking Noises From Corsair H75 Liquid Cooling Module

[Falstad007]

The module attached to the CPU begins making this strange clicking sound after being left on for more than five hours, and it gradually grows to the point of being unbearable.

Funny enough, if the system is shut down or put to sleep and then immediately booted back up, the sound disappears.

Anyone else had any issues like this with liquid cooling?

It could be a number of things. If it comes and goes, it could be air bubbles going into the pump. That's not a good thing and can cause damage over time as the pump will over-rev when it has air in it.

Another thing is that it could be thermal expansion from the CPU warming up the water and increasing its volume, which can put some pressure on the pump housing. This is probably more likely than the air if it's a well used unit. Remember, these are closed loop, meaning air and water tight, so I think it is the water expanding. That explains why it gets worse over time too.

There's not a lot you can do with either issue, you'll just have to RMA it if you can't get used to it. If it's out of warranty, either you'll need to get rid of it or deal with it.

Yikes... I'd err more on the possibility of air bubbles being created, as I would assume a heat related issue would persist even after the system is turned off and immediately rebooted.

When I get home to a system with sound I'll be able to listen to it. Air bubbles is pretty unmistakable, so I should know pretty quickly.

That definitely sounds like air bubbles. Regardless, this shouldn't happen considering these closed loop systems are pressurized and this may indicate a potential leak. You should probably RMA it if you can.

Definitely bubbles.

I remember having this problem when I bought my H80i a few years back. It was a common problem back then for all Corsair AIO's, so search around.

First, check your motherboard settings and make sure nothing is throttling power to the pump. If you have any fans connected to the pump itself, remove them and try connecting them directly to the motherboard, or connect them to molex power.

If none of that works, request an RMA. Some people had fans that drew too much power, others (like me) got a bad batch of units.
