Cooler Master Seidon 120V Watercoolin damn noise ?

[WeylandYutani]

I had this one 6 Months now and it worked fine, it wasnt my desicion to buy it, it only bought it to have one before i get a Corsair Watercooling system. Yesterday it runs fine except the noise it always do with a bit gurgling sometimes because of air bubbles in the radiator.

The compressor now makes a noise like when you hold a small stick against a moving bicycle tire, a really weird noise. First i thought it makes it because it gets really cold this night but it doesnt stop after one hour, it only stops sometimes for a short time. And when it stops it dont do the default sound, it does the default sound but much more faster and a bit louder.

I have no idea whats in the compressor so i have no idea whats going on, is there a ball bearing in it or what and is there a way to repair it, what ever is going on there ?

I had it at a molex connection and plugged the pump now directly on the chasis fan connection, the loud noise is gone but it still does a noise but a different one, maybe thats normal. The last noise wasnt constant it as like trrrrrr trrrrrrr and now its only rrrrrrrrrrrrrrrrrrrrrr constantly with much less noise.

Maybe the connection doesnt had 12V, i cant tell because its a fan connection splitted in many parts.

Edit: ok it still does that to me, the noise is coming back, it stoped for a short time after switched the plug to the chasis fan connection.

Contact CoolerMaster and explain any issues u are having; they could replace it if they deem it is an issue worthy of replacement. Most common issues with those cheaper AIO Liquid Coolers is the pump noise and being faulty. I honestly do not understand why anyone would buy them. $150 or less is laughable for a good liquid cooling setup.

Edit: checked all my cables and it was a 4 pin Molex to 3 Pin Connection with only two Pins in it what is the Default 3 Pin Fan Connector with only 12V so everything is right at this point. So the Pump is really faulty, maybe the achse or mabye the bearing i dont know but it never does that noise and its really loud, i mean that loud that i can hear it through my big Headset with high Volume.

I already contacted them and still wait for an answer.
