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? 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. The Corsair iCUE H150i ELITE CAPELLIX liquid CPU cooler provides extreme performance and flashy RGB light shows. It sports a graceful design using a slender 360mm radiator paired with three 120x25mm magnetic levitation RGB fans. The base uses a split-flow copper cold plate with 128 micro-skived fins per inch. Skiving provides excellent thermal transfer and having such a high density will provide a lot of cooling performance.

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. When it comes to thermal resistance, Corsair’s latest AIO cooler initially seems to be slightly outperforming all of the 360 mm coolers that we have tested to this date. The average thermal resistance of 0.0808 °C/W is almost identical to the figures we received from the recently released NZXT X73, with Corsair’s MagLev fans giving the H150i Elite Capellix a small advantage in terms of acoustics. The base of the H150i Elite Capellix features a brushed copper cold plate which arrives with a patch of pre-applied thermal compound. The inside of the cold plate makes use of a set of dense, micro-skivved cooling fins to the tune of 128 fins per inch.User error - many parts for the system builder to correctly install and maintain, where AIOs are factory built and sealed. Just more pieces to have awareness around. rubix_1011 said:Meaning, if we were to provide cooling by comparison across the same decibel range for multiple cooler comparisons? Ex: "Here is how A, B, C and D coolers compare by thermal performance when running at 35dB?"Exactly. Lot of youtubers review fans this way. 50% and 100% or RPM does not cut in as depending on the fin shape and number, a lot of variables can come into picture. Something like 35 db, 40 db, and max RPM would be nice. Whatever you feel is "barely audible dB", "OK - not so disturbing dB" and "max RPM cooling" settings would be great. Many of the previous solutions from Corsair to hit our lab for testing have floundered in thermal results, leaving us with little choice but to remove points from the awards with a heavy hand. However, with what we have seen with the H150i Elite Capellix, with chart-topping results in extreme mode, and top-five finishes in balanced mode, sways our perspective of what to expect when it comes to the new Corsair sealed AIOs! So much comes in the box, which you are left wanting nothing when it is all installed and ready to run! 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. The Corsair iCUE software worked perfectly for controlling the fan speeds and RGB lighting of everything, while also showing the pump RPM. Another nice feature is the included iCUE Commander CORE can readily accept up to three more RGB fans. Installation is a breeze, as everything is labeled very clearly and supports basically every AMD and Intel processor released in roughly the last decade.

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.felicityc said:iCUE is a terrible software with obnoxious CPU overhead, buggy design, less control than other software, zzzz i hate icue and saying icue is the biggest + with the builtin command center no one liked or wanted (gee wonder why its included) makes me definitely go look to ekwb and just cut my own loop, might as well learn now With 16 RGB LEDs on a modern pump head design, the ELITE series deliver great cooling with the looks to match. 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. All ELITE CAPELLIX XT AIOs include pre-applied CORSAIR XTM70 Extreme Performance thermal paste for maximum heat transfer from your high-end processor to the cooler coldplate.

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. Meaning, if we were to provide cooling by comparison across the same decibel range for multiple cooler comparisons? Ex: "Here is how A, B, C and D coolers compare by thermal performance when running at 35dB?"

Possibly that is the reason. This morning I monitored the liquid temps on the pump starting the computer out cold (22deg celsius) and it gradually climbed on idle up to 35 deg celsius. The gradual heat increase from the gddr6 of the 3090 heating the case? Corsair's new H150i Elite Capellix is creating a bit of buzz, but not just for the reasons you might initially think when we mention the words ‘new AIO cooler.’ The H150i Elite Capellix’s performance aligns well with other 360mm AIO coolers in the marketplace. And Corsair adds value by including a Commander CORE hub / control module that provides system builders the flexibility to extend control and management of their PC beyond that of the cooler. Support for the iCUE H150i Elite Capellix covers all of the current processors! AM4, sTR4, and sTRX4 are supported out of the box for AMD, while on the Intel side, there are 115X, 1200, and 2011(V3)/2066 support. The last bit in the chart covers the five-year warranty. To make it even better, the depth of control and all of the options at hand using iCUE is astounding. What makes it a step above is the inclusion of motherboard and GPU lighting control! Anything RGB can be controlled with iCUE, so you no longer have to mess with multiple software suites, and there is the fact that the flow of colors in certain modes is synced so much better than was possible for us before Corsair stepped up their game! The Corsair H150i Elite Capellix seems to be getting the best thermal performance out of every similarly sized AIO cooler that we have tested to this date, outperforming NZXT’s X73 by a whisker. The performance seems to be fairly stable across most of the load range, offering predictable performance regarding of the load, with the exception of very low loads where the temperature difference is far too small for appropriate heat transfer between the mediums.
