Defective Radiator? (rattling noise inside)

[Nebu]

Hi,

My new radiator arrived yesterday. (First time watercooling) and I'm not sure if this is normal..

Well my Alphacool NexXxoS UT60 has a rattling metal noise when shaken or tilted... I'm pretty sure this isn't normal. Sounds a little like glass.

I have attempted to flush it out using hot water to no avail. Searching the internet a review of the radiator mentions this issue but not much more.

This was purchased through *another company*, not Overclockers...

So is this normal? Should I send it back to *another company*?

Thanks.,

rattling within the radiator pipes or the rattling of the fins on the frame?

I think within the radiator pipes, how can I tell?

Tbh it sounds like a combination of both, the fins are attached to the pipes, if a pipe is loose the fins rattling off the radiator cage would make a noise.

I'd send it back if in doubt.

Edit: Just given an RX120 and XTX360 a shake and both are completely solid, no noise.

Thanks a lot, I'd rather be 100% safe.
