Wouldn't the upward airflow to the dual rad and back 120mm provide enough airflow to deal with the VRM's?
The VRM heatsinks on most enthusiast boards would be enough to cool them semi-passively I would have thought.
If the VRMs are nestled around the CPU socket then they're still designed to be air cooled, unless they're pre-tied into the water cooling setup.
Most everything is a take off of original design practices simply because they have no idea what cooling the consumer will actually be using so the old standby design setup is used and it is performance designed to utilize the cooling of stock CPU cooling.
Intel and AMD motherboards are designed exactly the same way.
When a 120 rad occupies the standard 120 exhaust setup on a case, the airflow is actually impeded by the radiator fins, so that airflow really does not cool the VRs down on the motherboard itself.
You have to make provisions to cool those voltage regulators, or suffer the consequences, wondering if what you're running is good enough and knowing it is, is two completely different things.
It's been a known fact since the early days of water cooling, that once the stock cooler is removed some cooling has to take it's place cooling the motherboard VRs, but today it seems to be completely disregarded.
Until the motherboards VRs overheat and fail and they cannot figure out why.
The CLC CPU coolers getting so popular today don't have fine print warnings regarding this?
They should have!
Isn't it covered in the water cooling sticky?
It should be!
