Temps and Fan Noise on 5800X and H100i

Hi,
I bought a Ryzen 5800X and Corsair H100i Elite Capellix last week and I have some concerns regarding the temperature and the fan noise. On idle, the CPU's temperature is about 40c (on Ryzen Master), and the cooler noise barely noticeable, but on load (especially when playing games), the CPU's temperature can reach 70c with loud fans noise. I can’t tell the exact decibel level but from iCue it spins higher than 2000rpm.

I already set the q-fan config in bios to be ‘silent', selected ‘quiet’ fans profile on iCue, and limiting fps on the Radeon app but it doesn’t help much. I use a standard thermal paste (Cooler Master Regular) but I don’t think it’s better than the pre-applied paste. I live in Jakarta and room temperature can reach 30c, although it can be lower when I turn on the air conditioner, normally I only use it in the evening though.

I’m thinking about swapping the fans with the quieter ones but not sure to choose between value or performance products. I saw this comparison video on youtube (and hear how loud the stock ML120 fans are) and I think I’ll choose between the value Arctic P12, be quiet Silent Wings 3, or go with the Noctua NF-A12x25.

But I have some question before making the buy:
1. Between the 3 fans I mentioned, which should I buy in terms of a balance of value and performance? Especially on the noise level on load? If there are better choices please tell me.

2. The H100i included fans (ML120) are connected with this hub that’s powered by a SATA port and connected to a USB 2 header, while the CPU fans port is occupied by the pump. Where should I plug the replacement fans?

3. Does a ‘performance’ thermal paste really makes different results comparing to a regular paste? If yes, I’m thinking to buy a Noctua NT-H2, or is there a better option?

Please help, thanks in advance.

Ultimately, you'll have to decide if noise is a greater concern than temps.

I'm noise conscious to a degree, so I'll tolerate higher temps for less noise. You may be the opposite.

Noctuas are very quiet and usually come with Low Noise adapters than can make them even quieter. I've never seen the need to use them so far.

Presumably, your BIOS has some degree of fan control as well. That's a good place to start and may make low noise adapters unnecessary. You should be able to get the fans to spin near 500 rpm or lower without adapters.

I do use Noctua paste, but would be hard pressed to tell you it is noticeably better than another product.

If you are interested in traditional case intake or exhaust fans that are restricted by an ordinary grill or nothing at all, I'd consider the Noctua S or A series.

If the fan will be blowing into something more dense, like heatsink fins, maybe lean more toward Noctua P or F series.

The Noctuas probably would NOT be the best choice if temps are your highest concern and you need to move a lot of air......but for a given volume of air, they are extremely quiet.

Maybe you can get some use out of this pic; it's a test run by Ed Hume a few years ago.

"LNA" means using Noctua low noise adapter.

"ULNA" means using Noctua ultra low noise adapter.

I use neither of those, just the standard cable.

I just reviewed some of my notes....if blowing into a heatsink of some type, I'd probably get a Noctua P as first choice...if noise conscious. Second choice would be a Noctua F.

Either of those would be noticeably better into a heatsink than the S or A series.

Thanks Dude and ignatzatsonic for your replies.

I try to maximize my cpu (and especially my gpu) with high settings on games, tbh I did freak out when the cpu reaches 90c. But then I read articles and a lot of people saying that temperature is normal.

I think I prefer a balance of performance and noise, I chose a 50% fixed fans speed percentage on iCue an hour ago and played some games. The fans are quieter now and the temperature at 90c (max), I'll do some testing to maybe lowering the temperature a little bit more.

Considering it's for an aio radiator, so Noctua P or F will be a better choice? There are Noctua NF-F12 on my local store. With 1700 rpm and 22 dB(a) specification. With you more leaning towards a low noise config, what do you think about these fans?

All things equal, the P....going by my prior notes. And from memory.

Graze the Noctua web site.

But not by a large margin. My Noctua U12S air cooler came with an F12, so Noctua thought it was suitable for a heatsink, rather than a P.

I've never owned a P and am not sure if a P comes as standard equipment on any Noctua cooler. But as of a couple of years ago, the P had the highest static pressure (slightly more than the F) and was therefore the marginally better choice when pounding on something dense like a heatsink.

In a real world test, you might not see any temp differences between the F and P...each situation is different, just like your sensitivity to noise.

If you can get a P online at near the same price as the local F, I'd get the P, but I wouldn't have any qualms at all about the F.

They are all "quiet". I'm using an F as a front intake blowing into a simple grill and can't hear it at 4 feet and 500 rpm.

Any of them are going to be audible as you get up around 1000 rpm or get closer than 2 or 3 feet.

The S and A are better choices as standard intakes or exhausts where high static pressure isn't needed.

I’ll do some research on both the P and F series, thanks.

Then again, that is with fans set fixed at 50, so I would take the noise, or look at swapping out cooler. Just my opinion the choice is yours

Good options are Arctic cooler, or Kraken

I already reseated the pump, with a standard thermal paste. I think I’ll ask Corsair directly if these temperatures are normal or not.

The noctua a12x25 will probably be your best bet for performance and noise level for a radiator. Though costly.

My go-to paste for which I have obtained best results is Thermal Grizzly Kryonaut.
