Best enclosed water loop?

[sgtsmokey]

I recently just bought a Cooler Master Nepton 240m, I expected significantly lower temps. What I get is between 77c and 86c using Intel Extreme Tuning Utilities stress test, I know this is normal as thermal throttling doesn't start until it gets to 100c. However this isn't a stock cooler! 

Idle is 22c, gaming is 55c, full load peaks at 86c. Whilst using almost every other piece of software I have, I expect to be around 55c. But I have to render 3D animations and a like for university. So whilst rendering animations it may be running at 86c overnight, not just for small burst of needed power.

I have the pump and fans on full too, so there is no room for improvement there. After having a 6970 with a stock exhaust fan that sounded like a jet engine powering up, full speed 120mm fans are pretty much silent to me so all fans in my system are always 100%.

So instead of tweaking around trying to discover the problem, if there was one. I have just came to the conclusion that the Cooler Master Nepton is just a poor device. So on that note, which is the best performing enclosed water loop you can buy as I will just go and buy that instead.

Any tips on making it better I will be grateful for

Been stressing the CPU for two hours now, still caps at 86c and floats around 80c

What were your temperatures like before installing this?
And have you overclocked since installing this or are you still at the same speeds as prior

Maybe try refitting the block - my temps actually improved once, just by tightening the block down properly.

You are right! The block isn't down all the way, However it is down as far as the screws will let it, there is a point screwing it down where there is no thread to go any further. 

i taken the block off and the thermal paste is literally a half compressed blob on the surface. I am going to take it off one more time and replace the thermal paste with a more premium one over the one that came with it. 

I am down to 76c now by refitting the block

I solved the problem guys, a simple and stupid solution. 

The orientation of the water block made the difference lol. I fitted it so the cooler master logo (clearly missing) was the right way and now it works properly and have a max load temp of 58c.

I had to change to a push air config to make the tubing longer to make it fit that way.
