watercooling kit making crackling noises?

ive had a swiftech 220 apex kit fitted for a few weeks now. but last few days im getting the best way to describe is crackling noises at random times which sound like its comming from the pump is this air trapped or something else its nothing major just a bit annoying for me anyway. any ideas please.

sounds like it could be cavitation which is what happens when you get air in the loop. Shutdown and see if any air gaps appear in the tubing. Try tilting the case gently and see if any air appears.

Could be air trapped in the pump,try putting the case on it side to remove the air.

No problem mate

Also unscrew the filling cap on the res,this will help bleed air out of the loop.

You can run the pump with the res cap open,you should hear a hiss when you unscrew it,just dont spill any of the water,i put bog roll round my res while bleeding.

i thought when i open the res it will bubble and overfill if it is still in motion?. my res is three quarters full will this solve the problem do u think doing this thanks for you help i apprechiate it

Can you elaborate on this please? I don't see how having the cap open will make any difference at all to bleeding.

Happened to me too.. it was a little piece of grit that made a crackling noise whenever it went through the pump, probably from the second hand rad I bought.

I'd empty it all out, and rinse through the rad thoroughly

yeah looks like im going to have to bleed and refill which is my last resort. i left res open last night and the noises have got a bit less and not as noisey its seems its getting better but very slowly?. will unscrew pump tommorow give that a shake and see if i can release trapped air that way.
