CPU block vs Monoblock

Hello guys,
is it worth to buy Monoclock instead of CPU block ?
What is benefit of Monoblock ?
 
A monoblock cools both your CPU and the VRMs - voltage regulator modules - responsible for delivering power to your CPU.

Practically, monoblocks are seldom worth it. VRMs are designed to run hot, and usually equipped with adequate heatsinks to handle the thermal load. Watercooling them might help you eke out those last few MHz in a fully-tuned manual overclock, but only if power delivery due to hot VRMs was your problem to begin with, which is unlikely.

Additionally, monoblocks may not mount to your CPU's IHS as well as a regular CPU block. This is because the VRMs are surface mounted to your motherboard and the CPU is "floating" in a socket. The monoblock cannot move higher or lower with your CPU like a regular block can in it's spring mount, because it has to make contact with the VRMs which are at a set height. There are additional manufacturing tolerances at play in the IHS's final z-height. I actually had an EK monoblock that didn't make contact with my CPU at all after I relidded it. Most people won't have that problem, but it is an inherent one to monoblocks - the height and clamping force are non-adjustable.

Monoblocks are mainly bling.

I couldn't have said it better myself. One final note, is that monoblocks are specific to the motherboard they were designed for. CPU blocks can often be used on both Intel and AMD CPU's, or modified to support additional CPU's and sockets with different mounting brackets.

Absolutely. A CPU block will last for years and years. A monoblock will last until you change motherboards. Also, monoblock selection is very limited. They are only made by a company or two, and typically only for high-end motherboards which, ironically, already come equipped with the most robust VRM cooling solutions from the factory.

And as a result of the above, monoblocks are basically for looks.
 
Thank you very much! I have ASUS R6E and looking for monoblock but after that topic is better to stay with my CPU block.
