CPU overheating with Enermax LiqMax II 240 water cooler.

[Heianir]

Hi, im new here, trying to figure things out. So this thread's tittle is self-explanatory, and you can check the system I'm running in my profile description.
Sorry for my english in advance, not my native language but I'll try to elaborate.

The thing is, i've been running this PC for only a year and recently my Cooler fans started working real loud - that got my attention to - why is it so?
Turned out my CPU is overheating under moderate load (playing Overwatch or any other shooter game i.e.) to approx 70-80 degree celsius.
I re-mounted the pump with some fresh thermal paste, but it didn't help. My system keeps overheating (as I'm writing this it's on 60 C with only the browser running). At booting it is around 45-50 C, which cant really be normal, right?

The questions are following:
- the cooler is at fault? One of the tubes is way hotter than the other...
- is it something to do with the motherboard?
- could it be software-based malfunction (viruses?)?
- airflow problem? Shouldn't be the case since Fractial Design cases (pun unintended) are really good at preventing that.

I'm open for any suggestions and advice from you guys.
I haven't been OC'ing it at all btw.

You could try and plug the water pump into a different fan header and see if that works. I would try the CPU-opt fan header or check to make sure it's properly inserted in the water pump header.

I'd just RMA it. It obviously worked fine for a year, and it has a 2 year warranty.

The 2 tubes temperature differences concerning me a bit the. Can someone elaborate how it should be with AIO wasted coolers in that regard?
Btw thanks, I will try to re-plug the pump and see how it goes!

One of the tubes carries the hot water away from your CPU to the radiator, the other carries cooler water from the radiator back to the pump/block.

Yeah, but the loop temp equalizes to within a degree or two. You wouldn't feel the difference in temp just touching the hoses.
That rad is plugged.

Sounds like the pump is slowing down in a death throw

Either there's resistance in flow or the pump is dying or dead. I would also recommend in RMAing the AIO.
