Both AIOs use the same generation of Asetek pump, which is more than capable of handling the heat output of an AMD Ryzen Threadripper or Intel Core i9 processor, especially when paired with a massive 360mm radiator. A major difference here is the type of fans used. The Elite Capellix comes with three ML RGB series blowers, while the more expensive Elite LCD has ML ELITE fans. Currently the radiator is set to top intake, with the bottom case fans also being intake and the sides being exhaust. I originally had the radiator set to exhaust with bottom/sides intake, but tried reversing it in hopes of remedying the issue. This is actually the second Elite Capellix AIO I've gone through; I returned the first due to a noisy pump, though it also had high liquid temperatures as well. Ambient temperature is ~22 C, it's winter time and in a basement. From a cold boot, the coolant starts at 25 C and constantly creeps up from there. I've tried setting the radiator fans to both exhaust and intake which didn't seem to make much of a difference. I've repasted this CPU about five times now as well. Install the 4 Intel standoff screws into your motherboard. Make sure all 4 screws are tightened until secure.

However all that said, when I ran the O11D as a dual 360mm radiator exhaust and completely passive intake from the rear and bottom, my idle coolant temps were no where close your levels. My max load levels were about your idle temps in the Winter with a similar 22C ambient. Something isn't quite right. The part I don't like is with the glass off and a 22C room ambient, it should take deliberate gaming load or hours of idle time before you should see a coolant temp creep to +13C over ambient and frankly I don't think it should ever be +13C over ambient at idle in that case. The Corsair iCUE Commander Core XT Smart RGB controller is brilliant for hooking up all your fans and RGB lighting with up to six channels for each. For RGB LEDs on the AIO itself, you'll find some on the pump housing and included fans. The former can even be upgraded with an optional LCD kit. In setting fan speeds, this is much simpler as we can define the PWM control of the fan to be exactly 100% or exactly 50%, which is a precise measurement of the fan RPM with very minimal average fluctuation over time. How does this compare your internal case or room temps? Most people will idle about 4-7C above the room temp, but this is very case and power level specific. Someone with a TR on High Performance in a glass box is going to be quite high, while an old Sandy Bridge that drops to 0.60v and stays there will be quite low. This seems to be where you are losing ground.

With the side panels off and at idle, the coolant temp reaches about 34.5 C (Balanced preset) or 38-39 C (relaxed custom curve). So about 2 C cooler. This seems abnormally high, as I also have an NZXT Kraken Z63 280 mm AIO attached to my 4790K in my old build and the liquid temperatures stay sub to low-30s on a similar fan curve to the Balanced preset. I'm not sure whether Corsair is using a different type of coolant that heats up easier. On the Balanced preset, my CPU temps are pretty normal in the 30s - 40s while performing mundane tasks with occasional spikes to the 50s/60s. On my custom relaxed preset, it idles closer to the high 40s once the coolant heats up. It seems like these fans aren't very efficient at cooling the radiator, as I have to run them at max speed for 10 minutes or so to get the coolant temps down to the low 30s. NOTE: Your cooler pump head should have thermal paste already applied. If you want to use your own thermal paste, make sure you thoroughly clean the cold plate of the pump head and the integrated heat spreader (IHS) of your processor with isopropyl alcohol and lint-free cloth. Setting a fan curve in CAM that mirrors iCUE's Balanced preset, my liquid temps now sit at 29 C idle and get up to 35 C max under load after an extended Cyberpunk session. This is much more in line with what I expected. CPU temps have also gone down about 10 C across the board, now idling in the low 30s and 40s while barely going over 70 under load (mostly stayed in the 60s while gaming). 50% fan speed will peg the liquid at 35 C, though if I opt for something more silent like 30% fan speed, the liquid still only reaches about 38 C under load.

Everyone seems to be making all-in-one liquid CPU coolers, and Corsair has been in the business for many years now. Most AIO solutions make use of Asetek's pump and AIO design, including the Corsair H150i Elite Capellix. It's almost identical to the Corsair H150i Elite LCD, aside from a few notable differences (namely that display).

OUR BEST PERFORMING RGB FANS

Processors have become far more powerful over recent years with more cores and better efficiencies throughout the manufacturing process. Still, AMD and Intel are in a constant struggle against heat output in the attempt to extract as much performance from internal components as possible. This is where AIO liquid coolers come into play. Yeah the Delta for gaming doesn't necessarily Alert me. FWIW I took the fan filters out and it did make around a 3 deg celsius improvement. Room temp is 71deg F or 22 deg celsius. So having an idle temp in the high 30s seems strange.

Also, setting to a decibel 'value' also isn't entirely accurate and can leave a larger range for operational limits. Example, there might actually be a variation of +/-300 RPM where the measurable difference of a single decibel is seen, but 300 RPM is actually a significant difference in the amount of airflow being moved. 1200 RPM and 1500 RPM actually end up performing quite differently. It becomes difficult to replicate test runs without variables based on decibel levels alone as the same measurement of 35dB for one test can easily fall outside of acceptable deviation.

PÁSESE AL LCD EN CUALQUIER MOMENTO

Are these liquid temperatures normal? Or perhaps the 5900x just runs hot and this is a sign that the coolant is doing its job? ML might make a slight difference (1-2C), but not really worth fussing over unless you are at a specific temp limit. The delta for gaming (39 to 50C) is basically at the +10C I generally quote as expected. It's the 39C baseline that is higher. You may want to go to a manual fan curve. Even the quiet one will blast the fans at 40C and that is idle. If the interior temp is also 39C, there is nothing you can do with the fans to make it less. Once your cooler is installed to your motherboard, it is time to connect the fans and pump to the iCUE Commander CORE.

over ambient at idle seems too high for me. It seems like you have the radiator as top exhaust. So bottom and side are intake? This seems like too much to be a airflow issue, but take of the large side glass off at idle and see what happens.

EXTENDED TUBING AND EASY INSTALLATION

The gpu will certainly heat up the inside so the Cyberpunk results don’t surprise me. The prolonged time after gaming at high temps suggests environmental heat, but can also be a restricted cooler. How does the 48C compare to something like the motherboard sensor or any other internal temp data? This is great in concept, except that the reality is that not every cooler manages to reach the same dB level at peak operation or lowest noise levels as every other cooler. Some coolers are not seen to operate at 35 or 40dB while others easily exceed it. These same coolers in comparison also
