4. They are noisy is you don't spend more money to buy/add/change fans
5. When they leak water they can destroy hundreds of dollars in PC hardware
All of the above has been confirmed by countless hardware review sites so it's not really debatable but that won't stop fanbois from arguing their subjective opinions.
The Corsair H100 is the only current CLC that offers equal thermal performance to the high end HSFs and the H100 is still a poor value and noisy unless you change/add fans.
If in spite of the above facts, you are Hell Bent on owning a Corsair/Antec or other brand of CLC - By all means knock yourself out. The HSF Police will NOT come to your house and arrest you for making a poor CPU cooling decision.
BTW, I have seen zero reports of mobo issues with large, high end HSFs so I don't see that as an issue though case or RAM clearance can be an issue.
Points 1, 2, 4, and 5, are pretty much meaningless.
Thermally inefficient? They are very thermal efficient, even when compared to the top end dogs. They may not win by a large margin, even losing sometimes, but they are definitely thermally efficient.
They are not a poor value. They are priced very similarly, and even if they cost $10 more that $10 cost to me is worth it so you can actually SEE my computer inside my case. I'd rather not have someone look into my case and be like "nice heatsink bro", because that is all they can see.
99% of the time they are going to be very silent. I am aware there are cases where people have had noisey pump motors, but for the most part they are very silent especially when paired with silent fans
Same thing goes for leaking, as with all hardware there is always bound to be defects. Leaking is another very
slim chance to ever happen with those units.
Point 3 can actually be taken into consideration since silent fans can get quite expensive especially when added on top of the already premium you are paying for a closed loop system, however IMO I still think they are pretty damn silent without buying third party fans.
Anyways, air and closed loop aside.. I believe the best option would be a custom loop IF he is willing to throw down a little more money. It'd offer the most superior performance while maintaining near silent operation(especially if he didn't even bother using a fan, which is totally doable) and then it'd also give him a lessen in building a custom loop of his own.
