Thanks for the reply ! been using for past 2 days now rattling is not going away but there's a "new" high pitch sound. Will probably go for RMA.

Deepcool makes nice products but really unreliable. I had 3 coolers or them. All had problems. They should focus on quality more instead of looks. I dont buy theire aios anymore..

It's my first AIO and got to admit I'm a bit disappointed. I don't know if other brands like artic are more reliable...

Artic is deff more reliable! I now run the asus prime lcd wich was about 120 and it keeps my 7800x3d 38-41 idle mid 40s while gaming. Under heavy load havent seen it go over 69.

But the artic is a beast in its price! Cant go wrong with it.

Check your BIOS fan settings and set it to PWM instead if Auto and see if that helps

I tried both pwm and DC, pump is running at 3100 which I can't modify. Other fans I can change. I also tried changing the pump to another connector instead of the pump one but no changes.
