So I just upgraded my GPU from a 5700 (non-XT) to a 3070FE and after installing it and all drivers, I noticed my CPU idle temps and load temps increased dramatically. While they are all still within acceptable range, the sudden increase has me concerned something else may be going on.
My CPU is a 3700X with stock cooler, mobo is a B550, and the GPU is the only thing that has changed in my system. I did have to upgrade the version of HWINFO I was using since I could not get the old one to see the 3070 and the new version had the setting for "Power Reporting Deviation" which got me doing some research. No other settings were messed with other than changing the CPU fan curve in BIOS while trying to drive the temps down.
With the 5700 installed, my CPU temps would be the following:
Idle = 36C
Load = 65-68C
Stress Test (CPU-Z) = 80C (after 60 seconds)
Multi-Tread Score = 5480 (CPU-Z Reference = 5433)
Single-Tread Score = 512 (CPU-Z Reference = 511)
With the 3070 installed, my CPU temps are the following:
Idle = 43C
Load = 78C
Stress Test (CPU-Z) = 92C (after only 10 seconds...I immediately stopped it)
Multi-Tread Score = 5321 (CPU-Z Reference = 5433)
Single-Tread Score = 468 (CPU-Z Reference = 511)
Prior to this version of HWINFO, I never had the "Power Reporting Deviation" setting, but understand it only means something when under full load. These are the number being reported:
Idle = 92.8%
Stress Test = 49.3%
CPU PPT 53.171W
CPU PPT Limit 60.4%
Something else I've noticed is that the spikes have become much more frequent and more noticeable than before. Just opening Chrome and typing this sees spikes to 69C and average spikes in the upper 50C/low 60C when it would never get above 55C during normal tasks. Now the spikes are going from 44C to 58C to 42C to 69C and they seem to do it constantly...and they're lingering at those higher temps for several seconds whereas before it would be a quick spike then back to normal.
Ambient room temp is 25-27C, which is a bit hotter than normal, but it's been hotter in the past and this was never an issue. I put a floor fan blowing directly on the case and the idle temps have dropped to an average of 38C from 43C...still doesn't help the increased spikes when using Chrome or other applications, though.
Could changing a GPU affect CPU performance this much? My 5700 was a blower style card, so perhaps the 3070FE is creating more heat in the case (this much, though)?
Does nVidia software use more CPU than AMD? I have not tried putting the 5700 back in, but I suppose I can when I have some extra time just to see what happens.
Any other thoughts of what might be causing it?
Thermal paste issues?
Failing cooler?
Faulty sensor?
Windows "Power Options" issues (I did notice a change in these with a Windows update recently...just don't remember what I had it on)?
I'm hoping it's just something simple and I'm overthinking it.
EDIT: I tried to attach a screenshot that shows HWINFO, Ryzen Master, and Cinebench R23 all running, but it would not upload...here's a link, instead. Note that Cinebench was only running for 24 seconds before these temps were reached. Before, it would be running for minutes before ever getting close to 90C. Unfortunately, I do not remember my stats from before.
