Trying to figure out thermal throttling

[Ophir peleg]

Hey guys, 

I bought new computer and build it myself -> 

AMD 5800x - No OC

AORUS B550 ELITE V2 

32GB 3200Mhz 

H100I RGB PRO XT

antec 750HCG  

GTX 1060 3GB

coolermaster TD500 mesh (with 3 front fans and 1 output fan) 

 

I'm getting thermal throttling - I'm using CPU-Z for stress CPU, and HWiNFO64 for monitoring, and I am always in 90c and up to 4300MHz on the cores... 
I tried to put all the fans on full speed and see if they changes anything, but getting no change... 
I'm thinking maybe the CPU cooler isn't strong enough for 5800x? 
or am I missing something?

 

another issue that I'm getting is when I turn the fans on BIOS to Normal I do not hear them ramping up, but when I am on Full Speed they are hearable  

Thanks guys!

The 5800X gets extremely hot, because it's a 105W TDP CPU with only a single CCD, so all the heat output is focused on a very small area inside the IHS. I don't think there's any way around that, but at 90°C you're not yet in thermal throttling, it's just boosting less. Real throttling would be sub 1 GHz, so it should be fine performance wise. Are you using the AiO as intake or exhaust?

The BIOS-profile "normal" might limit the fan speed, it's probably more of an everyday use profile for less noise, not an extreme cooling profile.

Are you 100% sure you took the plastic film off the CPU block before mounting? I'd get some isopropyl alcohol to clean off the CPU and block, and some fresh thermal paste and try remounting it.

hmmm, pretty sure, yes.. but switching the thermal paste is a good idea! thanks

90C is the limit with the 5800X for my understanding - so it can't go above.. 

the AIO cooling now is exhaust, but I tried with intake also and same performance, from cleaning wise I need to switch to intake hahaha, I'm too  lazy 

 

for the BIOS-profile - on the curve it seems like it should go up to 100%

same problem with the cooler as intake with the fans as push?

 

then ur hitting a big thermal wall

Just changed the AIO fans to be intakes, but no sign of change.. 
This cooler supposes to handle the 5800x, am I wrong?

Yes but maybe not at 1.475v   its kinda much. (under 1.4  is recommended)

The 1.475v is maximum -> Volt when running CPU-Z Stress is 1.225 

I'll change the thermal paste and update performance

Your cooler should be totally adequate, theres always something better but a 240mm AIO shouldn't hit the 90s. Is your pump running at 100%?  Always a chance theres a bad mount too its happened to me before could be that simple.

ok but what if 1.2v is a thermal throttle volt
