Antec Kühler H2O 620 CPU Cooler not working (Complete Newbie)

Hello, so I've been having some trouble with overheating with my computer recently (probably due to the weather). However as I didn't experiencing these issues when I first got my computer, I thought it was the dust getting to it.

I noticed that my GPU AND my CPU was both overheating on different occasions. Therefore I did a spring cleaning by wiping almost every single fan in sight, mainly my
-GFX card (MSI N580GTX Twin Frozr II) fan (one was not spinning well probably due to the lube haven't lubed it yet)
-and my CPU Liquid cooled fan. (Antec Kühler H2O 620 CPU Cooler)

Well after doing some cleaning, I noticed some problems with my CPU cooler. The fan was blowing much harder, everything was cool and good however, my CPU was still extremely hot.

I tried doing some research and it was quite confusing.

Basically, I think the pump isn't working / something is faulty.
One side of the pipe is extremely hot, the other isn't at all. Fan is blowing well, CPU is stil extremely hot (overheated).

If anymore information is required please do ask.

Additional Information: My computer kept overheating 5 - 6 times in an hour, maybe it has something to do with it. I read something about the pump being shot.

Thanks for reading my post and hopefully there is a solution to all this. :(
