It seems the Intel vs. AMD "Heat War" has no end in sight, in the immediate future at least anyway. The CORSAIR H150i has been my "tried and true" cooling solution for a while now. A quick "back of the envelope" calculation revealed something a bit scary to me. 1. The newest generation of AMD and Intel chips seem to require heat removal capacities that will exceed even Quad Radiator + 2 liter reservoir cooling capacities unless a water chiller is added to the loop. 2. Without monitoring the aforementioned hypothetical cooling solution, one could quickly reach the "radiator bottleneck constraint" whereby even the Ford Wind Tunnel fans would do no good in terms of keeping the heat from gradually increasing beyond the CPU thermal shutdown limits. 3. I believe Thermosyphon Technology will be required in order to support sustained, very high overclocks on these high performance chips. Therefore I... ...started building a Single Stage Dual Phase Active Refrigerant-Based Thermosypon. Currently, it can run the newest Intel 10-core chips at 5.3 GHz for 24x7 operation without getting the Blue Screen of Death. I will report back with more info later on, if there is interest.

OK finally! Sorry for the long delay between posts. I did not bookmark this forum's URL and I had experienced another hardware complication as well. The only way I could get all 3 fans of the Corsair H150i to spin faster than the default "quite mode" of about 400 RPM was to do the following: 1. Locate a strange cable with a Micro-USB Hub connector on one side and a 10-pin monstrosity on the other end. 2. Attach the MicroUSB side to the Corsair H150i and the 10-pin connector (with many unused connectors) to the motherboard. 3. I had to download the CORSAIR ICue software from your site. 4. The "Performance" tab on the ICue program allowed me to specify the max setting, which spun the fans as high as 1500 RPMs and the pump speed even faster! This lowered the temperatures from 97C to about 92C when running all 8 cores using a stressful prime number "sieving" application which was looking for 10-million digit prime number candidates. So all's well that ends well. The computer is running much cooler now, even under the harshest tests on all 8 physical cores on the Intel i9-9900KS.

Ok here they are. First boot and first run of the morning. System was nice and cool at start. Temps are usually higher. I know the voltages are on the high side. This is for 5.1 GHz. I'd just like to get the fans on the H150i to spin faster. They are hardly moving. The airflow over so much surface area of the fins could DEFINITELY lower the temperatures, even for a short test such as this. I know there is an asymptote out there, but I am nowhere near that on the heat curve. Just so you know, I've done some crazy experimental stuff, such as 2-stage 2-phase passive thermosiphon cooling: I've coupled heat exchangers to two Corsair H100s coupled to two cooling loops; one liquid, one vapor. I just "missed something" when I hooked up your H150i this time around. I am a "tinkerer" which means I am bad at following directions. And this is the case I built for the i9-9900KS. I made it big enough to house a quad-radiator at the top if I need it, but I started with the Corsair H150i. You can see it is pretty big. And sturdy as can be.

All 3 of the fans are kind of bundled together and connected to one SATA power cable. There is a 3-pin connector of which only one pin is apparently a data delivery line for fan speed control. This is connected to the CPU Fan Header. So my guess is all 3 fans are spun at the same speed ... but from ... where? Any idea?

Thank you, I will double check that as soon as I can. And here is a screenshot showing the temperatures. I read the "FAQ" post about the water-cooled radiators and I saw a mention there, but didn't make the connection until seeing your post! Thanks again.

My current system, an Intel i9-9900KS, overclocked to 5.1 GHz (and sometimes 5.2 GHz) is scoring in the 5200 to 5300 range on Cinebench R20. You can see a video of the Cinebench run here: [ame= ] [/ame] The temperatures get high, over 90C sometimes. I thought I had the fans set at 100% in the BIOS on my Corsair H150i but they seem very quiet and never throttle faster. Is there a BIOS setting on my ROG motherboard I am missing?

You need more monitors and larger speakers :)

Greeting to everyone. Just wanted to thank CORSAIR for making an awesome cooler. The triple radiator (H150i) in my custom build is shown in the YouTube video below. I also used a CORSAIR 1200W power supply. And I think you will like the build log. I designed everything, the case, the custom mounting brackets for the internal monitor and the slide-in tray to hold the wireless keyboard and mouse, even the power button. The case is made out of aluminum and plexiglass. The CPU is an Intel i9-9900KS overclocked to 5.1 GHz on all 8 cores. Could not have done it without the awesome cooler, so thanks again CORSAIR. Enjoy! [ame= ] [/ame]
