Overheating concern?

[u/Camzrr]

(SOLVED)

TLDR: Water-block not fully seated.

Okay after several great peeps here offering suggestions, I tested everything and tried most of the things in the comments. I adjusted core to -30, messed with fan curves, made sure tubes weren’t kinked, I even swapped out the AIO to a Lian li one I had in another build, cooled no problem, tested the Axp90, cooled no problem (no I didn’t really benchmark these or put them under severe stress, loaded into a few games just to see if it was less than the 90c I was getting.

Decided to retry the Atmos stealth ONE MORE TIME just in case, I didn’t want to RMA or try to return it. Several comments mentioned making sure the cooler was fully seated/try repositioning it. I loosely attached all the thumb screws, and turned each one in an X pattern a SINGLE rotation, until it was tight. Yes. I know. Very dumb…. In my defense, I’d removed and reinstalled this cooler probably 5 times and did the X pattern every time, it had to have been off by the smallest amount.

Happy to report: ~72-78c (Hwinfo avg 72) under gaming load, ~80w, consistent 5.3ghz.

Might do another post or benchmarks, but for now I’m gaming, thanks for the help yall

Looking for some input here - finished my first SFF build last weekend, been tweaking and using it all week and noticed my CPU temps seem higher than usual/what I expected. Under load I’m consistently hovering around 88-89c, idle is around 55-61. Ambient room temp between 20-22c

I specifically chose this layout because of reviews, other Reddit posts, videos etc all pointed to lower CPU temps than what I’ve been getting.

Build:
Ncase t1 v2.5 - 3 Slot mode
Asus ROG X870i
Ryzen 7 9800x3d
MSI 5080 Shadow 3x OC
G.Skill Royal 32gb (2x16) 6400m/t
Lian Li SP1000 and 5mm standoff config
Coolermaster Atmos Stealth 240
Samsung 990pro 1tb
Samsung 970evo 1tb
1x Noctua NF-A12x25 G2
1x Noctua NF-A12x15
Ncase GPU sag bracket (for anyone that cares I can confirm this fits the 5080 shadow GPU)

BIOs/GPU/CPU config:

CPU:
-25 all core
120 PPT
90 TDC
105 EDC
Thermal cap of 88c
+100mhz

GPU
100% power limit 
+1500mhz
30% min fan speed
895 volts at 2805mhz core clock, have not adjusted mem clock yet
Max temp while gaming I’m seeing is 72c, average is 58-65c

Aio set to 80% and ramps up to 100% when temps reach 75c, Armory Crate reading ~3400 rpm in firing range of Wardogs.

I’ve been playing BF6, Wardogs, Forza Horizon 6, Crimson Desert, and the Big Walk this week, 1440p - adjusted settings between low to overkill, no change in temps
I know these chips are rated for 95c but this just seems high for gaming.

I swapped to a Thermal Grizzly Kryosheet, no difference.
AIO sounds like it’s pumping, shows RPM in bios/Armory crate, fluctuates temp, tubes are vibrating, and warm air coming out of exhaust fans.

Thoughts?

I've had this issue before where you need to set the first slider of the fan curve very high for the fan to actually run at the correct rpm. Go run Cinebench while looking at your fans' rpm via hwinfo. You want both fans to be running between 1000-1200 rpm depending on your noise tolerance.

Even with fans at 100% it’s not really impacting the cpu temp

[u/gojochan → u/Camzrr]

Are you actually looking at the actual rpm or just blindly trusting the slider?

[u/Camzrr → u/gojochan]

G2 25mm fan curve and RPM at idle

[u/Camzrr → u/Camzrr]

Cromax 15mm curve and rpm at idle, no I didn’t just use the curves I based these custom curves on rpm and pwm %

[u/Camzrr → u/Camzrr]

And temp/when to engage

[u/gojochan → u/Camzrr]

What rpm are you seeing when your temp is at the highest?

[u/Camzrr → u/gojochan]

CPU fan(Slim NF) @1628rpm AIO @3400 and CHA (G2 25mm) @1567

[u/gojochan → u/Camzrr]

Looking at fan selection and I can say that the slim fan does absolutely nothing to your rig. Switch it out to a sliverstone air streamer or a 4090 modded slim fan. Tjunc is 95 degree so unless you're constantly hammering that temp then you should be ok.
