5900x/3090 benchmarks and cooling thoughts

Received my new PCS system recently, borrowed a Zotac 3090 (500D SE, 32GB RGB Pro Vengeance 3200mhz, H100i, HX1200 PSU, 570-F Strix) . Big difference from my old i7 -3770/Radeon 7850 (!). Played the first half of RDR (just) on low everything at 1024x768, now gone straight to 4K ultra max settings (60hz) with the new rig. *Might* have noticed a difference haha

System is running hot and noisy on 4k ultra settings (Zotac 80C @ 80% fans), CPU up around the same temps, H100i temp 45C. I'm going to add in another LL120 as a rear exhaust with the aim of bringing this down a bit. The system is silent unless under load. If I'd had my time again I would probably have ordered a H115i but it was incompatible with the RGB RAM which looks great in the case and I'm not going to run ultra very often anyway. Have a 6800XT Sapphire Nitro+ due to arrive on the 28th December. May help some though to know that if you use this case (which is gorgeous), the standard cooling model 3x LL120 (intake) and 2x ML120 H100i combo may not be quite enough if you plan to max everything out. Nice to try out a 3090 but it's overkill for what I need it for. Have chosen the 6800XT to future proof VRAM further down the line (16GB over the 10GB of the 3080).

Interesting results on Timespy DX12:

As delivered:
score 17,682 (graphics 18,689, CPU 13,547, 45.51 FPS)

PBO off, Ryzen Master auto o/c:
score 17,657 (graphics 18,723, CPU 13,350 44.85 FPS)

PBO on, Ryzen Master auto o/c:
score 17,509 (graphics 18,534, CPU 13,335, 44.80 FPS)

PBO off:
score 17,625 (graphics 18,697, CPU 13,306, 44.70 FPS)

Offset voltage (-0.2), no oc:
score 16,687 (graphics 17,540, CPU 13,085, 43.00 FPS)

As I'm not an overclocker anyway, I'll probably leave it in "as delivered" mode now.

One question I do have - I've set up HWinfo to exclude the iCue components as they are known to clash, but after excluding the iCue the CPU fan sensor on the MB is showing a crazy high 4500-7000rpm. Is this a false reading as the H100i is installed?

Are you sure it's the CPU fan and not the pump?

Here's a current grab below from HWinfo (been idling for past 30 mins or so) H100i pump temp is currently 28.9C but has risen as high as 45C when I was gaming in ultra yesterday :

Also, never bothered with sensor analysis with my 10 year old machine so new to HWinfo - does that chipset temp of 66C look normal?

Thanks for your help mate

When did you order the 5900x?
2:02pm on launch day 5th November. Originally ordered without GPU, then I added in a 6800XT at 1.58pm on that launch day, so was probably one of the first to get that bagged. However, went back to non-GPU build a couple of weeks ago (live chat told me they were pessimistic about getting XT6800s before Jan) and it moved very swiftly after that. Build/test/despatch within 48 hrs. Also of note the build day start matched the date from the automated emails right from the start. So I'm confident that PCS are doing as good a job as they possible can right now.

Potentially silly question, are the fans fitted correctly and correct orientation?
Cool air coming in from the front 3 LL120s and heat being chucked out of the top by the ML120's on the H100i so yep I think so! I've never been able to game at anything above medium settings before so guess a bit of extra heat and fan noise is to be expected at settings that high.

Sometimes the CPU pump is set to low in iCue, make sure it's on balanced at least as that gives a significant thermal reduction whilst still being quiet.

Yep I noticed how quiet the pump was, left in balanced all the time and fine tuning custom curves for rest of it now. That's made a difference already rather than using quiet mode which is anything but quiet if the temps are allowed to spike (y)
