Question about PNY RTX 4070 Super Verto fan speed issues.
Question about PNY RTX 4070 Super Verto fan speed issues.
Hello,
I’m just getting started with hardware diagnostics, so I hope this helps clarify what’s happening with my GPU.
I own a PNY RTX 4070 Super with dual fans (new in September 2025). It hasn’t lost any FPS, there are no visual artifacts or crashes. However, recently the fans have started spinning at full speed in a high-demand mode. Normally, when games like Cyberpunk 2077 run at maximum load, the fans spin between 97-98% with speeds around 3100-3200 RPM. The temperature remains within acceptable limits—around 75-78°C for the GPU and 106-110°C for the hotspot.
Recently, I’ve observed a change in its behavior. Either one or both fans switch to full-speed mode at 3600 RPM, producing a loud, jet-like sound. This lasts a few seconds before returning to normal and repeating. Interestingly, the fans seem to go into this extreme overdrive without any noticeable jump in GPU usage or temperature increase, as they can operate at 3100 RPM even when the GPU reaches 78°C, then instantly switch to overdrive without a corresponding rise in heat.
I’ve checked both manual and automatic fan speed settings:
- Manual curve: shows Fan #1 spinning at 3600 RPM.
- Automatic curve (VelocityX): also indicates high-speed operation.
- Idle system after booting Windows: confirms normal idle speeds under load.
- Fans running at 3150-3200 RPM without a corresponding temperature rise.
I’m not concerned about the noise, though it’s noticeable when it reaches 3500+ RPM. The sound is steady and consistent, but it becomes more pronounced above 3500.
This situation wasn’t present a month or two ago with games like The Last Caretaker or Subnautica—those fans definitely draw attention, and it was too distracting for focused gaming.
My system specs:
- CPU: Ryzen 5 7500F
- PCB: MSI MAG B650 Tomahawk
- GPU: PNY RTX 4070 Super 12GB VERTO Dual Fan
- RAM: 64GB DDR5
PSU details requested. Check recent logs in Reliability History/Monitor or Event Viewer around the fan speed issues.
PSU: MSI MAG 850W 80+ Gold (A850GL)
The PC was assembled using all new parts during Q3/Q4 2025; the only remaining older components are a few SSD drives from my previous system.

Reflecting on past experiences - most of the time Razer Game Manager Service and REDILauncher (from Cyberpunk) are experiencing crashes.
I think it's best to manually adjust the fans to 100%, which brings them to 3,200 rpm, so the 3,600 is just an internal reaction to an emergency situation, though I'm not sure what specifically causes this response.
Game related issues - correct?
Uninstall the games to determine if the fan problems continue or change.

This: "the only 'old' parts are a few ssd drives from my old system."
How many is "a few"? Configuration?
Makes, models, capacities, how full, how connected, model, capacity, how full?
If the problems continue then disconnect all but the boot drive. Focus on stablilizing the build.
Then carefully add back the other drives one at a time allowing time/a couple of restarts between drive additions,
Thank you for the update. Please maintain clear communication.
Users typically keep fans idle at 0RPM during standard Windows, YouTube, or Netflix use, or they spin at low speeds (800-1000rpm).
The overdrive fan spinning feature activates only when the GPU is under heavy load in games.
Regarding the older hardware – my old PC had four storage options:
1. A 4-disc drive (second slot on PCB): Samsung SSD 970 EVO Plus 1TB (70% free)
2. Three SATA drives: Samsung SSD 860 EVO 500GB (90% free), Samsung SSD 870 EVO 1TB (60% free), Crucial CT500MX500SSD1 500GB (30% free)
3. A main new drive – Samsung SSD 990 PRO 2TB (NVME slot 1 on PCB, 60% free)
I’ll remove all but the boot drive and await further instructions.
Drives not connected, no updates.

Reading back:
What exactly are those "specific conditions" regarding "Auto Mode"?

I don’t rely heavily on benchmarks or similar tools. Most people just gather data in Windows, maybe do some calculations and try to make it more visually appealing. It’s useful when the output is neatly organized and easy to grasp, but it can also be exaggerated or mislead.
I often question measurement precision, error margins, significant figures, and so on.
For example: what are the limits for minimums, maximums, averages? How were they measured, and how precise was the determination?
Trying to input a parameter to two or three decimal places might not be very meaningful if the actual measurement has an accuracy of one or more units.
I won’t dismiss such methods entirely—some users find them valuable and informative—but I remain careful not to become too fixated on any single measurement or result.
"Measure with a micrometer, mark with chalk, cut with an axe."
Stick to the fundamentals and keep the overall context in mind.
Yes, disconnect drives leaving only the boot drive. Observe system behavior and performance. If everything seems fine, gradually reintroduce other drives one by one. Give time and allow restarts to see if fan speed issues return.
Experiment with swapping fans to check for changes.
Use the tools, but don’t lose focus on the core issue and its symptoms.
It looks like another bad case and a poor airflow issue. Fans spinning at 3200 rpm to maintain 75-78°C and a hotspot of 106-110°C is a problem. My Asus Dual 4070 uses a custom curve: 40% fan at 40°C, next slope at 75% at 75°C, last pin at 85% at 100% fan speed. It never exceeds 72°C with 72% speed and runs in the 60-65°C range during folding and most games. Case and cooling setup?
