Be quiet silent loop water cooler fail

Be quiet silent loop water cooler failed after only a few months

The installed water cooler

With the very hot weather in the United Kingdom this summer we decided to try to improve the cooling on our computers by replacing our air cooled heatsinks with a sealed loop water cooler system.

At the end of July we purchased a pair of be quiet Silent Loop AIO 240mm water coolers from https://www.quietpc.com/bq-silent-loop at £115 each to install into our workstation computers which we use for both work and VR gaming.

The initial installation of the cooler systems went without any issues but after approx. 2 months the cooler in Andrews computer started making grinding noises and so we thought there could be air in the closed loop so we refilled and removed all the air from the system but the problem remained and after a few hours of running the noise would turn to a high pitch squeal like a metal to metal worn bearing noise.

We removed the cooler from the computer and fitted the old air cooler back into the machine and everything was quiet again!

Raidator block

This week after only 77 days use, the be quiet Silent Loop AIO water cooler in my computer started to make the same noises and despite removing the pump and radiator and rotating the components with the pump running to try to move any air in the  loop, the high pitch squealing was still there and after a hours use on the computer it started to also make a loud rattle and vibrate badly.

Another problem I found with the radiator block fans was when they would run above 40% speed they would resonate badly and vibrate.

I have now replaced the water cooler with an air cooled heatsink again and the computer is now quiet.

The manufacturers website shows that the silent loop has a “3-year manufacturer’s warranty“ but unfortunately we did not keep the boxes for the cooling systems so we cant return them as they are both clearly faulty but need to returned in their original packaging.

After this experience with water cooling, we are going to stick with air cooled systems in the future.

Same problem here with Be Quiet! Liquid cooling AIO silent loop, it seems that Be Quiet! Discontinued all AIOs and will swap yours for an air cooling system of your choice. A big let down really as you will have to send your AIO back to them and wait for their decision...I'm buying a Arctic Freezer 2 AIO instead now, I've seen a lot of positive reviews, good price excellent performance.... And the rattling noise seems to be rather common amongst silent loop AIOs ...

Same here, 6 months after installing silent loop it starts making some very loud rattling noise from time to time. Contacted Bequite! And they are acting as if it's the first time they heard about it.tbry offered a replacement with a air cooler if I send it back and let them inspect my silent loop... I will never again buy a Bequite product. Shame on them

You're mounting it wrong. watch Gamersnexus' newest video on proper radiator placement.
