    I had to hard to swap motherboards (ASRock X399 Taichi failed on me) and now my 360 is noisy... like a fishtank. It sounds like someone is taking a shower in the other room or something. I had no noise from the system on the Taichi board, but have a ton of noise now.

    While I was swapping the motherboards, I didn't take the cooling fully apart, but I did lay the case on it's side to make it easier to work on. I wasn't concerned about air bubbles, since it's a sealed system.

    The only other thing I would think could cause it (besides something going bad... it's only a few weeks old) would be maybe different voltage to the point between the header on the ASRock and the one on my new board (Asus ROG STRIX X399-E Gaming). There are three different headers you can use. After reading this thread, I did what most do and plugged the pump into CPU_FAN and the radiator fans into CPU_OPT.

    Temps seem normal (32-32C for CPU) so far (no OC), but the bubbling is annoying. Anyone experienced this?

    I have the exact same setup and have no problems that I can detect, however I have 4 systems running in this room. putting my ear right up against the case though does not indicate anything more than a gentle hum from the case and rad fans

    I have so much stuff running in this room, it's a miracle I can even hear it. That tells me it's pretty loud. The main source of noise in here is my server rack, which has five Dell R710s, two Dell 1gbps switches, and two quanta 10gbps switches running... and I can still hear the gurgling.

    When you say you have the exact same setup, are you referring to just the cooling, or the motherboard as well? I don't see it listed in your signature block. If you do in fact have the same board, what do you have the pump and rad fans plugged in to?

    I don't know about the ASUS board, but I know on my ASRock Fatality I have the pump plugged into the port marked pump and set it to be always maxed out. Check the bios settings maybe the Asus is trying to adjust the voltage of the pump to reduce it's reported RPM as if it were a fan and causing issues. IIRC the Enermax instructions tell you to make sure to set the speed of the pump to max no matter what header you use. A simple way to test this is to run a short high load test like prime 95. If the temp goes up the board should ramp up all the fans it thinks it can control to max in a few seconds and if the noise goes away then that is the problem.

    That's actually a good idea. I'll drop Prime95 on and see what happens!

    The absolute hottest I can get it is 51C, running Prime95 on maximum heat. The fans are obviously louder. It's hard to tell if the burbling is any quieter... it's still there. Maybe 50% quieter?

    I wonder if I should try plugging the pump into the W_PUMP header and just put the radiator fans on the CPU_FAN header.

    It was definitely that header! I have it on the water pump header and it's quiet as can be. I can only hear the fans on a full load with Prime95 now. Thanks for the ideas. It's even cooler at idle, as well (28C vs 31C).

    For anyone using the Enermax LiqTech TR4 systems and an Asus ROG STRIX/Extreme/Gaming, do not follow the popular advice (pump on CPU_FAN and radiator fans on CPU_OPT). Put the pump on the W_PUMP+ header and the radiator fans on the CPU_FAN header.

    Gald to see it worked out. (y)

    FWIW I keep both my 280s on the w_pump/cpu_opt headers on asrock x399 and make sure to set those as water pump/DC-max and not fan mode in the bios. Asrock boards at least have this level of granular control on these kind of headers.

    It always reads around ~2800 "RPM" done that way which I assume is what the pump should read at full power on any other board. Radiator fans duplexed on a cpu header in PWM mode.

    that's most likely what the "issue" was, the header was set to dynamic speed instead of full speed.

    I didn't see that in the BIOS, but I could've missed it.

    in the bios's fan control section you should be able to set it to dc and then 100% to keep it at full blast. or something like that.

    Well it's definitely running a few degrees cooler, so that CPU_FAN header must be dynamic, like you said. However, I moved the radiator fans to that header after I moved the pump to W_PUMP. I don't mind the radiator fans being variable.

    If your pump's "RPM" is up around ~3000 that should be full power. (LPM is what actually matters if we could easily measure it)

    The DC mode and full voltage options is only available for some headers, but the bios for asrock x399 boards are all basically the same - the power option comes up after you change the mode from PWM to DC. Integrated pumps are meant to run all out but radiator fans on a cpu linked PWM header is my usual way too, no need to be louder when its idle.
