Oct 4, 2016. #2. From the sounds of it, it sounds like air possibly? It also sounds like an old HDD reading/writing. Because it's an AIO cooler it is a bit more difficult to get air out, one person said "Shake it whilst the pump is on" but that doesn't sounds like a good idea.
This is a common problem that many people face. Radiators are not supposed to make noise, but if yours does, it might just need some maintenance. A couple of easy fixes could rapidly get rid of all that racket. There are many reasons why a radiator might be making noise. Some of the most common reasons include: There is an air leak in the system
Close the drain, then the pressure reducing valve. Repeat for each zone. FInally, re-open the line valves for each of the zones and at the boiler; and return the zone valves to automatic position. And then make sure you have reopened any line valves that you had closed.
A burning smell is actually one of the most common that emits from electric radiators in particular, especially in the case that they are being turned on for the first time in a little bit. Dust can form inside radiators during times they are out of use, and if not tended to before they are switched back on, the newly fired-up rads will burn

When the computer boots up, all the fans start spinning but this humming is distinct from the rest of the case fans. It sounds similar to if you sit next to an osculating table fan - how the sound of the hum changes as the fan rotates toward and away from you but the tempo is quicker. It also tends to get louder as the computer heats up - it

It sounds like the clicking noise is not the radiators, but the pipes expanding and contracting. The clicking noise is sometimes due to the pipe moving in the clips that are holding it, or maybe where the pipes are touching a joist and making this clicking noise when it expands when the heat comes on. The radiator cannot actually create a buzzing sound as there are no moving parts in it. Buzzing is usually caused by vibration, which comes from a moving part. The moving parts in an AIO are the pump and the fans. My suggestion is to eliminate them one by one. Start by unplugging the fans first. See if the buzzing goes away. it is normal to hear/feel the water in the radiator and it should be okay. When i was building my pc (i have a ek aio) i was able to hear the water when i moved the radiator. If you are concerned about leaks as long as theirs no water on the outside you should be good. 1. eclark5483. This noise control article series discusses the diagnosis and cure of heating system noises, including heating equipment noise, heat piping or ductwork noises, radiator noises, steam pipe banging, and steam radiator vent noise control. We describe just about every single noise that might come from or have to do with building heating systems. 9yBeLUq.
