Laing DDC-Pump

Hello,

i recently bought this pump: https://www.alphacool.com/shop/pumpen/pumpen-laing/5080/laing-ddc-pumpe-12v-ddc-1t-plus
because my old one stopped working. I replaced the old pump then and everything was fine for a few days. Now the pump is still functioning normal. If it turns on that is.
Sometimes the pump does not start and my pc shuts down because of it when i start it.
I tried pluging the pump directly to 12V without turning on my PC and it shows the same behaviour. I plug it in and sometimes nothing happens at all and in all cases where it turns on it has a massive delay of up to 10 seconds.
I don't think this is normal and my computer does not seem to be the issue since it also doesn't work on a 12V Adapter properly.

Should i refund the pump for a new one?
