Corsair iCUE H150i ELITE CAPELLIX Liquid CPU Cooler (33 Ultra-Bright CAPELLIX RGB LEDs, Three 120mm ML RGB Series PWM Fans, 400 to 2,400 RPM, Zero RPM Mode, Corsair iCUE Commander CORE Included) Black

Product Information

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. 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.

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. 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. 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.

EXTREME PERFORMANCE THERMAL PASTE

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. Are these liquid temperatures normal? Or perhaps the 5900x just runs hot and this is a sign that the coolant is doing its job?

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. 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. 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. 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. 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 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?
