Switching from custom loop, back to air cooler.

I would like to chime in here and say as for water-cooling, the reason most people who set up custom loops claim that the noise profile is not different from either a high-end air cooler or a 240mm and up CLC lies in how the fans are set up. In my specific case, I base my fan curves on the coolant temperature and not the CPU temperature (like most people). This is based on the fact that the radiator is there to remove the heat from the coolant, and the waterblock over the heat source acts as the medium for the coolant to move the heat from said heat source and to the radiator. So, it makes far more sense to me to set up my fan curves based on coolant temperature. This gives me two advantages: 1) I can set the fans to very low RPMs and still get similar temperatures compared to running them off of the CPU temperature, and 2) the transition between higher RPMs and lower RPMs is very smooth, and linear, so I don't get those sudden spikes in fan RPM transitions.

 

If I was going to build a work computer, then yeah, I would want to air cool the whole thing to make servicing faster, and remove the inherit risk of damaging components from a leaking CLC or a custom loop, even though both solutions (all their components for the latter) are built to tight tolerances.

That's a good point. Maybe if I intently listened to my PC, or measured it with some sort of device then there would a difference, but there isn't enough of a subjective difference for me to notice.

What do you use to measure coolant temps?

I use a Bitspower G1/4 temperature sensor plug connected to a Touchaqua G1/4 T-Fitting (2 Female, 1 rotary Male). This is connected to the outlet of my pump/res combo. For fan control and thermal monitoring, I use the Asus Fan Extension Card and plugged the fans into one header (with the provided 3-way fan splitter that came with my EK-KIT P360). All fan curves are set up in the BIOS, eliminating any need for additional software for control.

 

Fans are Corsair ML120 twin-pack fans. IIRC this is my fan curve setup:

 

Minimum: 20% Duty Cycle @ 30º C coolant temperature (reason why I set the coolant temperature this high is my ambient room temperature tends to hover around this range)

Middle: 55% Duty Cycle @ 40º C coolant temperature

Max: 100% Duty Cycle @ 60º C coolant temperature

I've never seen that Fan extension card before, that thing seems pretty interesting. 

Looks like it's only supported on ASUS boards

Yes. Some of their motherboards has it bundled. My Asus ROG RAMPAGE V EDITION 10 came with it.

I don't think mine has one. Asus i370 gaming I believe it's called. It's the z370 mitx board. It did come with this thing for wi-fi however. Which I thought was a nice touch, even though I use an ethernet cable.
