Yeah... I have the same concern. And also worry about the heavy weight of cooler. Okay cooler is usually around 1kg by itself. Top cooler even weight more (IMO crazy), which bring real concerns to me.

And you are right about large heatsink blocking internal components and create accessibility issue.

I like water cooling for its 'clean' look inside casing. However, I read many forums that water cooling suffer leaking and spoilted pump issue. Well, I guess it is just the same thing like car version.
Is lowyat really selling Phanteks PH-TC14PЕ ? Btw, the brand design looks like just copy D14 and other models... very similar.. Maybe no more room for creativity...
For motherboard, I am thinking of Z170X, which I like the Gigabyte Gaming 3 as it is very beautiful. I likes its use extra stronger material for the slots. And not to mention having 2x PCIe M.2 slot.

While for processor, I am looking at the plain i7 6700 with K since I never overclock my processor.

Guys, any suggestion on water cooler that is known to be realible and easy to clean? Or i7 6700 stock cooler actually sufficient? 

Next questions, normal usage... stocket cooler how much higher temperature than aftermarket? 10 degree only? Not sure worth or not...

Or any other suggestion that is not over kill in term of weight? But still way better than intel stock? And also easy for cleaning 

Wait a minute... you mean you using i7 6700 stock cooler and normal temperature is only between 32-36 degree? In air-con room?

It sound like I should use stock cooler?

Ok.. I finally bought it.

I wanted the stock cooler... But when I look at its size especially fitted on other actual system, I cannot help but really feel like a joke with its tiny heatsink.

I really cannot use the stock cooler. I felt too unsecure with the tiny size. Thus I end up topping up my budget by getting the Hyper 212X, which at least the size make me feel more comfortable. And the weight of 500 gram should not harm the board as well.

I saw someone with D14 and D15. The size is over kill...
