Full coverage MOBO water block - overkill?

[caligrown1985]

Hello,

 

Long time lurker on these forums.  I have a question regarding my new build, and I can't seem to find a reliable answer anywhere.  I need more information regarding full coverage CPU water blocks, i.e. water block that covers the processor and chipset.  Are these types of water blocks overkill? Will they provide any noticeable performance improvement?  The reason I ask is because when I look at videos on youtube regarding PC builds I rarely see a full coverage block being used.  Is this because they are simply more expensive or are they designed for an enthusiast with money burning a hole in their pocket?

 

Thanks in advance!

Depends on case airflow. I had such a large loop on my old rig that the GPU AND CPU would run passively under light/medium load, fans kicked on under fairly heavy load.

 

 

But the chipset and VRMs got extremely hot, so I had to add some fans for case airflow. Using a full cover block would have avoided this.

Custom water cooling in general is overkill so putting the mobo in the loop is just extra icing on the cake.

Full cover blocks, are more for when you want your build to look extra good or for when you are planing a silent build that wont have much air flow.

 

If you have 10gig NIC or PLX chip on the motherboard, then it can be a good idea too cool them (if they get used a lot). Same problem as with m.2, a few minutes at the time is no problem. Half an hour or more and you need to start looking into adding more cooling.

Do you have an approximate figure for "extremely hot" versus the temp after you added the fans?

110 degrees dropped to 50 on the VRMs, chipset was like 90 and also dropped to 50
