Going back to what started this whole air vs. water debate...a guy was asking about what he needed to cool a 1700 for help with a purchasing decision given that he already has an Evo. My stance was that he does not need to spend the extra money for reasonable overclocks. I stand by that.
That said, I don't disagree that custom loop > AIO > Air

Sadly for cooling i have just stock cooler(wraith spire),i had previously on my old system and hyper 212 evo and read that was same as this one.
My 2 request advices would be wich cooler to get.My first choice would be Noctua nh-D15.Is an AIO better than that one?My 2nd point is the psu.I have a Corsair RM650x and for cpu i had just the 8 pin and not the +4 one.For overclocking do i have to change my PSU?
I tryed some OC,didn't succeded to get more than 2400 stable for ram and 3.8Ghz on cpu.
My settings are:
CPU core voltage 1.33125(affraid to put cpu on high voltage as i do not to have a short life but willing to listen to advices, i am just a beginner in oc)
VDDSOC voltage override 1.20
DRAM voltage 1.35.
Thank you for your help
Then this happened.

If you live in a cold climate I agree with you, but fact is id never be able to keep my processor under 60C without my aio water cooling setup. I know people praise some of the Noctua brand air coolers but honestly water is where its at for consistency. It is a fact for me in NJ tested over many years. Some people dont have the luxury of cold ac in the home all the time and it vastly affects overclocks during the summer.
4 GHZ is a pipe dream for me on an air cooler, with this h100i v2 I could stay at 4 ghz if I wanted to, but I decided not to 24/7 due to the voltage, im happy at 3965 1.38 voltage with no LLC, this 8 core is going to chug away at games for years to come
So, I turned on the baseboard heaters, and turned up the voltage until I got out of my comfort zone...which was 1.425V, with overshoot being above 1.50V. I couldn't pass IBT AVX Max at 3.875GHz. I settled on 1.400V @ 3.85GHz for this test.
Initially I was going to get it 30° in my apartment and do my testing, but in the interest of not wasting power (or sweating my balls off), I did my testing with an ambient of about 25°C (~23.5°C closer to the floor). If you want to correct for summer temps in places with no AC then go ahead and add 10°C to the ambient/load temps. The delta should be the same.Warning: Spoiler! (Click to show)
BIOS 0604 Settings:
- CPU: 3850MHz (154 FID / 8 DID) @ 1.400V (Offset + 0.2125V)
- LLC: Level 1 VCore, Level 1 VSoC
- RAM: 2400MHz 12-12-12-32 @ 1.25V, SoC @ 0.93V
- Everything else: Auto
System draw @ idle: ~95WIBT AVX: 13 runs @ 12587MB,
- Speed: 180.5 GFlops
- Total system draw: 305W peak
- Ambient: ~24°C
- CPU: 71.4°C, VRM: 63°C, Chokes: 84°C
Didn't get that error this time which is nice I guess.Warning: Spoiler! (Click to show)
So...if you plan to run IBT AVX on maximum @ 1.4V and pump out >180 GFlops (210W above idle) in the summer time, and you're okay with, say, 80°C CPU temps, then I say an Evo is enough. Again, I don't disagree that an AIO or custom loop wouldn't give you lower temps or that lower temps aren't a good thing. But do you need
to spend another $100+? That's a personal choice. I'm just providing some real world data.
I also started up F@H to provide some data on a more realistic scenario. Heater's still on right now and I'm seeing over 24°C where I measured before on the side of the case.F@H,
- CPU Usage: 78 - 89%
- Total system draw: 225W
- Ambient: ~24°C
- CPU: 62.0°C, VRM: 47°C, Chokes: 62°CWarning: Spoiler! (Click to show)
Aaand I went ahead and paused the folding to get a couple Cinebench 15 numbers just 'cuz.Cinebench 15
- Performance Bias in BIOS: Auto
- Single Thread: 156
- Multi Thread: 1702Warning: Spoiler! (Click to show)
So to summarize:
Is a 212 Evo sufficient for an 8-core Ryzen @ 1.4V during IBT in the summer? Yes.
Is it sufficient for even higher voltage in a more realistic scenario? Yes.
Is water cooling better than air cooling? Yes.
Are lower temps better for your CPU? Yes.
Is a 212 Evo sufficient for "extreme" overclocking? Probably not...but I wouldn't recommend it for that case anyway.
Does bardacuda have dust bunnies under his desk? Yes.
EDIT: Forgot to set folding power to "full" for that test. Took another pic with it on full, but the heater is off now so ambients are a little lower (maybe 1°C). It doesn't seem to be stressing the CPU any harder anyway though.Warning: Spoiler! (Click to show)
EDIT2: Found a better work unit. Measuring 23.5°C on the side of the case at the moment.Warning: Spoiler! (Click to show)
