High temps with NZXT Z73 AIO + 5800X3D (Radiator cool to the touch?)

[bruisedwayne]

Hello! Sorry to bother but I'd like to seek some opinions here. Wondering if my Z73 AIO cooler is having issues and if I should RMA it. I've been using it for a year.

 

Previously, I had a Ryzen 3600 and the temps were constantly at 70°C or more.

 

I have since changed to 5800X3D and re-pasted with a good amount of kryonaut. The CPU temps have never gone below 50°C and goes to about 89°C while on Flight Simulator

 

My ambient temperature is 24 degrees celsius (airconditioned room in the tropics). Not sure if it matters, I am running one 3840 x 1600 and one 2560x1440 display.

 

What worries me is that the temps do not improve even if I were to set the CAM pump and fan curves to 100%, the 360 radiator is always cool to the touch no matter the fan/pump settings. (cooler than body temperature).

 

According to CAM, the pump is spinning at 2300rpm at max, and I do feel some vibration on the tubes. There is an audible electrical noise even with the case closed when the pump is at 45%.

 

Also, during re-paste, I notice there's a mark on the cold plate that couldn't be removed with isopropyl alcohol, not sure what it means. I don't think it should affect the performance, right?

 

Feeling rather stumped, would greatly appreciate any input! Trying to avoid purchasing a temporary air cooler just to send it in for an RMA, if it turns out that this is a perfectly normal phenomenon.

This CPU runs hot but shouldn't really hit 89°C during gaming. 

I see it spiked to 1.3V which is weird because the CPU is limited to 1.25V which is also quite excessive and that's why people use Curve Optimiser to get it even lower and drastically reduce temps.

 

 

But it's possible that HW Monitor is just reporting things wrong, can you use HWinfo instead as it's much more reliable? 

 

Do you have SenseMi Skew in BIOS enabled or disabled? 

Depending on what it's set to it can drastically affect reported temperature even though the actual temperature may still be the same.

If the CPU were at 75+ the radiator should be, once the water heats up, at 50-60 or even more. Definitely not room temperature.

Both tubes should be warm, one slightly warmer than the other, not by a much. And water circulation should be felt.

 

Also, which motherboard and bios version?

Did you use the same cooler on the 3600?

My 3600x reached max 70°C in Cinebench on Dark Rock 4 (not pro). Maybe your AIO should indeed be RMA. Also note that the airflow in my 3600x pc was not great..!

it's the B550 Aorus Elite v1 (latest bios version F15D)

would curve optimiser decrease the performance of the CPU? 

 

here's a screenshot of HWinfo, not sure I understand what i'm looking at here.

 

as for SenseMi, I will need to check, let me get back to you on that.

When starting the program, you need to select "Sensors only" to show the temperatures, voltages etc.

Here you go!

OK, still spiking to 1.3V which is really weird. May be a bad LLC or something the motherboard does automatically.... not sure tbh.

 

Curve Optimiser moves the voltage/performance curve so that the CPU can boost to it's max clock at lower voltages, it's technically undervolting mixed with overclocking. Some motherboard have it built in into their BIOS on newest BIOS version but some don't and you have to set it up trough windows.

You set it up by selecting a negative offset with the max allowed value to be 30. For me 24 works on all cores which drops the temp by about 15 C and makes the CPU hit 4.45GHz all the time on all cores as it's sitting at around 70C and not hitting 90C anymore.

 

Have you changed your CPU only or did you reset CMOS after doing so to reset the motherboard settings to it's default state? Something may have been left messed up from the auto settings on your previous CPU.
