Corsair H100i Pro RBG vs Noctua NH-U12S (Ryzen 5800x)

[Pikatchu]

I have upgraded my CPU to a 5800x for a month or two now, was running it with my U12S.

Due to high load temps with the U12S, I have switched it to a H100i Pro RGB hoping to lower temperatures. (I already own the AIO, did not buy one just for this)

The conclusion is that, no thermal change at all!

 

Cinebench R23 30min test peaks my thermal at 85C, under both coolers.

During games, this is the only slight difference, U12S stayed around 70C while the AIO stayed around 67C.

Casual web browsing still see temperature vary from 35C to 50C.

All the test were ran with a -0.0875 voltage offset.

 

I understand that the 5800x is known to be a hot chip, and it was my first hot chip to deal with. (My past CPUs were 4790, 8700, both non-k)

I plan to go custom loop just for my CPU, but I am not sure if it will make much of a difference since the AIO performed on par with an air cooler.

So there’s a few things to note that matter with this.

1. The surface of the cpu ihs, could be bad so that it’s not making enough contact to transfer more heat

2. The components on the motherboard not getting enough airflow

3. Is this deviating from other similar systems and cooling configurations

NHU12S vs H100i Pro in this case is like burgers from McDonalds US vs UK
If you want better temps, get a 280/360mm aio or a NH-D15 (reccomended)

The 5800x can take advantage of more cooling with more boosting. 

Did CB R23 scores change?

Nope, the same after 30min run.

1. After check paste spread, it looks okay.

2. As far as I know, from hwmonitor, motherboard component is under control.

3. This is where it gets confusing. There is a lot of different temperature report out there, but my is near average. Though, my is undervolted. Which is why I just try it myself and post the findings.

I am switching back to the U12S. The pump is generating a low hum, too noisy.
