VRM Temp spike to 124c
VRM Temp spike to 124c
Hey everyone! I'm talking about my overclocked i7 9700k running at 5ghz. During an AIDA64 stability test, my VRM temperature jumped to 124°C and there were power and current spikes too. I think this might be my high LLC setting (level 6), but it looks like a pretty big spike. Is this typical or something unusual? I've attached some pictures to clarify everything. Let me know if you need any other details. Thanks!
What board are you using? That chart/info is only relevant if there's a sensor on the board (and a sensor in the appropriate place!).
A 9700K at 5GHz, even at moderate load should have VRMs >38'C. So, if the "current" figure doesn't look right.... I wouldn't put too much weight behind the spike that's shown.
It's an Asus strix-e z390 gamin, I haven't installed a sensor. where should i put it?
The motherboard contains sensors in multiple locations, mostly where space allows, among various parts like between components, near the CPU socket, close to VRM units, and next to SATA controllers. Few parts actually include thermal strips in their design, unlike CPUs or GPUs which have them. I’m not sure if Aida64 is helping you, as I can’t recall a recent PC with a cooling fan reaching 10k RPM or a chassis fan spinning from low at 316rpm to nearly 2600rpm. It seems Aida64 likely uses AVX technologies in its stress tests, possibly with a 0MHz AVX offset for that specific configuration. This could significantly raise temperatures and affect power consumption. I’d recommend verifying these findings using HWInfo (not Hwmonitor!) and checking the sensor data only through the box. Using Prime95 v26.6 with a small FFT would be a good approach.
Thanks for the reply! It's strange that HwMonitor is displaying my CPU fan readings inconsistently, even though only my AIO 3 pin is connected—it doesn't actually control the fan. I also had a negative 2 offset for AVX instructions. My main worries were about VRM temperature spikes and current levels. I set power limits to max in the BIOS, but it's not normal for such a high jump. I'm considering getting HWinfo instead of Monitor. What are the differences? Thanks again for your help!
Hwmonitor is still available, though not updated often. It has been around for a long time and is well recognized. Created years ago, before many upgrades such as Sata, USB 3, pcie became standard on motherboards, leading to many confusing issues with incorrect addressing. With the increase in motherboard complexity, Hwmonitor now misinterprets signals like the 12v rail as 8.32v, tmpin4 as 255°C, and tmpin6 as -125°C—values that are physically impossible yet the system still functions. The author couldn't determine the source of the tmpin readings; the primary temperatures included CPU, VRM switches, Northbridge and Southbridge chipsets, with possible variations in combination. For LGA1156, Southbridge was only present on AMD boards, while Northbridge used to handle RAM/VRM/PCIe terminals and has since been replaced by PCIe as the memory controller moved to the CPU. I've observed some of these tmpin values measured, matching sensors close to a Sata controller at the bottom of the board near a fan header.
Hwmonitor once performed well, but its performance has significantly declined. Hwinfo now greatly surpasses it.
