Corsair H115i RGB Pro XT liquid cooler review

do you have super strict stability tests to run 1.35V ? I ran mine @ 1.26V and it was fine for gaming, handbrake or streaming (using nvenc) which is the intended use of the cpu anyway
I say this because obviously then you'll get lower Watts and temperatures, maybe I just got lucky with my 9900k...or simply got a stabler memory (memory no1 cause of failure when overclocking, just downclock yours to 2133Mhz or whatever and you'll see your system is suddenly very stable)

I own the H115 rgb platinum (older model) and it works great my only minus would be the pump that vibrated more than other aio and thus was hearable (maybe a defect ?) also that pump in the older H115i made Aida64 and other monitoring apps completely crash icue commander pros (when it worked fine with a H150 360mm) I hope they fixed that in this version
other than that I also ran my amd 3960x on older H115i rgb platinum thing for 1 month (until I received the parts for a custom loop) and it worked "okay" but using the cpu 100% in cinebench and the like would give me 90°C (stock settings) if you have one already you can use it on threadripper (pretty much the hottest cpu you can get 250-280W only for the cpu !) but it won't be "great"

Hi Hilbert

Would you say Wprime 2.10 is a good real world temperature test? So if I can get below 80c on Wprime on 5ghz with my 9900k, would you say that is safe for 24/7 use?

My 9900k needs 1.32v to be completely stable at 5ghz. But it can reach 90c after an hour of AVX stress testing like Realbench etc.

I've got a Corsair H150i, and my ambient temp is normally 28-29c (air conditioned room)

Honestly I've been running 4.8ghz at 1.24v, the temps are like 15c better overall. I just feel a bit uncomfortable with high temps just for a 4% performance bump.

9900k power consumption when performing stress tests with AVX depends on RAM performance.
Therefore, it is very interesting for me to find out what power consumption the 9900k has in the author’s test. For example, my 9900kf 5GHz 1.35V at 16 threads consumes more than 220W, RAM 4270MHz cl16

I think it is a very representable test ergo we use it, run 1024M and do that a couple of times. I am looking at different ways to stress for future articles, however, most applications tend to become a bit too viral to be called a 'real-world' test. I find wPrime to be quite representative for CPU load.

What I am trying to say is just like with testing GPUs, you can run Furmark and go completely viral on the GPU, as a program that works - but is that a real-case replication of real-world temps, I tend to think that is not the case. e.g. you are not driving a Ferrari 350 kph all the time either.

BTW I would not like it any proc running 80c 24/7 at 100% load. But for burst load, that's fine.

Aweseome thanks Hilbert!

I just ran mine at the same 1.35v and 5ghz and got 80c package, that's at around 24c ambient and also with Kryonaut. I would've thought a H150i might do 77c roughly like the Eisbaer, but alas the Eisbaer is victorious lol!

Do you do these tests with an open chassis? Or do you close the chassis as you're testing? I still rock an old school Cooler Master Haf-X lol, it was closed in my testing.
