Corsair H100i RGB Pro has questionable performance?

[Clippy]

I have a Ryzen 5 3600 Cooled by a Corsair H100i RGB Pro XT. I use my PC to stream and game at high settings and at one point with the stock cooler it would reach approx 85-90 degrees while at max load which is why I decided to upgrade cooler, that and asthetics. When I first installed it, I would always see my temps idle around 25 degrees and peak around the 50s or 60s, Not a long time ago my pc had to be reset and I had to install a new version of ICue (went from version 3 - 4 i think) and now temps Idle at 45 but still peak around 60. I thought it might have been thermal paste but after swapping a case and motherboard, temps still idle around 45. Does anyone know if the issue is with ICue, a fan curve, or something else. All temps were taken with Ryzen Master and is running currently at stock speeds.

It's because of Ryzen, how the CPUs operate. You can't avoid it.

Could you elaborate on what you mean?

It's just how Ryzen CPUs work. No matter what you try, the CPU will boost highest at lower current and in a basically idle state because it's allowed to use up to 1.5v automatically.

It's best to just accept the idle temperatures because they're basically impossible to avoid without seriously gimping your CPU's performance. Getting a better cooler only allows the CPU to sustain higher clocks for longer than with a sub-par cooler, it won't improve idle temperatures on 7nm Ryzen by much, only the load temps.

Don't even think about manually setting your voltage either, because for most 7nm Ryzen processors, anything above 1.2v could be potentially lethal to the silicon in some heavy workloads, causing slow degradation of the silicon and ruining the chip's ability to boost as high as it could when you first bought it. Tons of users have already done this because they thought that using closer to 1.3v or more was safe. The absolute ceiling of safety is between 1.2 and 1.25 volts at max current, whereas in an idle state the max is usually closer to 1.5 volts because higher current is the worry, not the voltage itself. That's why you'll basically never see your max boost clock in heavy loads and only at lighter loads, where the FIT allows the CPU to use enough voltage to boost as high as it can.
Don't become a statistic, just ignore the idle temperatures and forget about it. It's not worth worrying about.

While I can only guess as to the idle difference of 20C, it's really meaningless in and of itself, because load temperature is what matters, and that stayed the same (and 50C to 60C is really cold for a Zen 2 or 3 under load as well).

Chances are though, it was a result of something that happened with whatever the "PC reset" refers to, as it's such a vague term and could include a new Windows install (as well as changes of programs and their settings), BIOS settings reset (fan curve is a good guess), and so on, but again it's honestly inconsequential anyway. Only load temperatures matter and they stayed the same.

Either way, it was 25 degrees right at first boot after installing the AIO as far as I could tell from the OP, which isn't really out of the ordinary because the liquid isn't heated up.

If you run load or let the system run for a bit, you'll always get to the "true" idle temperatures and idle temps will pretty much always be hotter, all of the 7nm Ryzen chips are like this. When I first boot my PC up after it's been off for a bit, my idle temperatures start in the low to mid 30s, but then after a little bit it starts to hover in the 40s.

I don't even think that's necessarily exclusive to Ryzen either. I've noticed that on my GPU as well, where if I check it immediately after a cold boot, it's a bit colder than checked at idle, say, hours later.

I was just presuming OP was comparing like for like. If it changed, something changed with the PC reset, likely a fan curve or setting somewhere in BIOS or a program.

It's definitely something that AMD suffers from across most of their newer products. Granted it'll be a problem for everything but not to this extent.

without a overclock you are idling a little high nothing at all to worry about but def a little
high.make sure your AIO pump is at a constant 100% and set your fan curve to ramp up right away its easier to keep cool then to try to cool it down.

I could tell that you're an Intel user without even knowing your system specs. Like I said, it's how Ryzen processors (since Zen2/7nm) run at factory and automatic settings. I've experienced the exact same situation with my 3900X and thousands of users have complained about high idle temperatures across the internet and looking for a solution, but there is none.

I've tried aggressive fan curves, it really doesn't make a difference because at auto settings, your CPU will just be able to sustain better clocks and will just maintain very similar high temperatures. Idle temperatures can actually worsen as well because it'll constantly fluctuate; the CPU will boost with 1.5 volts, get too hot, downclock, cool down, and repeat.

There's only 3 solutions:
1. Manual voltage, ideally up to 1.2 volts as most of AMD's 7nm processor FITs usually don't allow more than around that voltage when running Prime95's small FFT torture loop. All depends on what your own Ryzen 3000/5000 series processor allows during that loop (the lowest voltage sustained and tracked); if the range was between 1.18 volts and 1.24 volts then your safest option for a manual voltage is to not exceed 1.2 volts. A heavy enough CPU load at very high levels of current being drawn by the CPU with too much voltage can gradually degrade the silicon and make performance at factory/auto OC settings worse over time in addition to making a manual OC more unstable as the silicon degrades. For Ryzen 1000 and 2000, around 1.36v was perfectly safe because it was a less fine manufacturing process, and Intel processors can handle similar voltages easily because of Intel's process. When Intel drops down to 7nm and lower, it'll suffer the same problems that TSMC 7nm does.

2. Disable all boosting and suffer major performance loss in exchange for better temperatures.

3. Just accept it for what it is. It's how these CPUs were made, and it's unavoidable if you want your CPU to be 100% safe, as the CPU is protected by the FIT only when using Precision Boost which is always active with the factory settings (no manual OC active), but disabled when forcing a set voltage.



TL;DR -- Since Ryzen 3000, it's just a fact of life for AMD users because of how AMD had to design their chips since shrinking the nodes they were using from 12~14nm TSMC to 7nm TSMC. It'll only get more constrained as AMD drops down to 5nm later on. These node shrinks help bring better power efficiency and better processors, but it also has significant risks when it comes to current and voltage. 7nm Ryzen processors have high idle temperatures because the Silicon Fitness (FIT; health management that protects the silicon) limits voltages based on how much current is being drawn by the processor, and since there's very little current being drawn when the CPU is idle, it's allowed to use up to 1.5 volts freely, which is where the advertised max boost clock comes from; a bursty single-core load when the CPU only needs to run a single core.
This is something that can only be understood once you've experienced or seen how 7nm Ryzen operates with your own eyes. Most Intel users don't know because this is an "issue" that is pretty much unique to processors using a very fine node, and Intel has yet to bring even 10nm to desktop.

I more meant the idea of something being cooler right after boot up as opposed to later, even though both are idle. What you're later describing more like the wider swings of temperatures Zen 2 and Zen 3 can show (both during "idle" and to a lesser extent load).

Since OP was referring to "idle peaks" I presumed they were comparing like for like though, and didn't just glance at it the first time and get a low instance, and then later and get a high one. Of course, that may be what happened.

Even I've seen idle temps as high as the 60s with a good 360mm AIO. Granted there's twice the cores and threads in my case.
