H150i 360mm temps on 9900k?

[FirstMateCapnJamesMchord]

I'm hitting 30-40c on idle and 51c in league and 65 max.  From what I've seen liquid cooling temps are supposed to be 20-25c idle and 30-35c max.

I am getting similar results on 6900K with Corsair H115i 280mm. This is normal for 8c/16t CPU like that, especially if overclocked with higher voltages. 

 

To get 30-35C max under load you would need to have a very powerful custom watercooling loop in well ventilated cool room, and considering how poor the heat dissipation is for these CPUs compared to GPUs, this is probably not even possible without below ambient cooling.

That would be custom loops I think, and even then in ideal conditions like you mentioned.

 

I have a 240mm rad for my 2700x and run about 28c when doing normal working loads like browsing, forums etc. Under load Max i've seen it do during gaming is mid 50's I believe. 

 

3-4H stresstest aida64 gave me a 77c average

you won't be getting close to the temps you want without a delid and probably a proper good custom loop

these are averages really (for idle temps), the liquid in your cooler will be the same as your room temp, so your idle temps will depend on where you live.

also i wouldn't worry about idle temps that much if you're happy with the load temps.

 

and yeah there's no way you will get 35C max with even an overkill custom loop, unless you live outside in -C weather..

9900k is a hot running chip

I have an EKWB custom loop (9900k & 2 x 1080TI's) using 420mm PE & 240mm PE radiators (both running a push/pull configuration with Corsair ML series fans) in a Phanteks Enthoo Luxe T/C case. It's near winter here at the other end of the world and my liquid temperature is currently 25°C. At idle-ish, the CPU is sitting at 29°C & the GPU's are steady at 25°C/28°C (they're plumbed in series) with an ambient of ~19C.

 

When I first built the loop last year, I ran some tests (15 minutes runs with a 20 minute cool down between each test cycle to normalise temperatures) using Intel's XTU CPU stress test & Heaven Benchmark (Extreme preset) to heat up the components to get a baseline. The fan curve (not too aggressive) is set to respond to the liquid temperature (using a Phobia 10kΩ inline temperature sensor) and results were performed at stock voltages & frequencies:

 

Ambient temperature: 21°C

Combined Test: XTU & Heaven run simultaneously

From what I have typed above, aiming for what you've seen would only be possible at a stupidly low ambient temperature with the silicon lottery winner CPU both lapped and under-volted. Your temperatures (if accurate) are pretty darn good as it is.

What are your ambient temps?

I do not know how to check.
