Corsair H55 Water not pumping on i7 3770-k

[Fayzann]

Hi, I just installed H55 on my i7 3770-k
The water pumped well in the start and the temp stayed very good, but like after 6 minutes or so the pump stopped working. I don't hear the water pump now

Are temps increasing after 6 minutes?

Maybe the pump died? If the temps are increasing after that then it's probably the pump.
