Maximum fan speed at temperatures under 47°C
Maximum fan speed at temperatures under 47°C
Hey everyone, I’ve been facing this problem. Living in a colder climate means my PC tends to run cooler in the morning. When I turn on the system, the GPU fan cranks up until I reach temperatures above 47°C—sometimes even 45°C. It slows down quickly, returning to normal only after a while. Before that, it makes a loud jet-engine noise. I’ve adjusted the fan settings, tried different methods, and even booted heavy games for a few minutes to raise temps to around 50°C. Then I close my laptop and start my day, but I’m worried it’s stressing my card. I can’t afford a new one, so I really need a fix soon. I’ve attached a screenshot of Task Manager and my Radeon card, but the RPMs are all zero—yet they’re clearly maxed out. I’m currently running Second Life at 102 FPS in the background and using the Eve Online launcher. Any tips would be greatly appreciated—I’ll give it everything I have.
Install MSI Afterburner when needed, adjust fan speed directly or build a custom curve.
I'm going to try that again. It seems I might have used MSI after Burning Board, but I noticed this starting up. I cleared it and kept going, but I'll give it another shot. Thank you for your quick reply—I'll update you soon. The image below displays my FPS and GPU temperatures/usage, but the GPU still shows 0 despite the Radeon label. The Task Manager shows 100% usage, which is confusing. I'm convinced, but fans are running at full speed. I'll attempt MSI in a minimal setup now.
Have you adjusted the fan speed to around 40%? Some cards restrict operation below a certain level, and pushing it too low could trigger a firmware error that makes the card suspect fan issues. This is why fans are usually set to full power—engineered for easier startup. The knobs on most fans default to Off-High-Med-Low to give them a strong initial push. Also, have you explored the Fan Control software? It works well in another system with an older RX 580, allowing precise fan management there. Just avoid setting speeds below 35% as the fans may shut down and struggle to come back up until they reach about 70%.
You adjusted the fan speed to 45% and managed to halt the back GPU fan. The first GPU fan started up but didn’t increase, while the second remains quiet. It seems higher speeds might help the system manage cooling more evenly.
When only a single fan is experiencing trouble, the issue may lie with the fan connector. If you've disassembled the card, it could mean the component was slightly shifted, causing the speed control pin to lose contact. In rare cases, if the fans have been vibrating over time, the connector might become loose due to movement from other parts, requiring re-seating.
I attempted the fan control program, but fan #2 didn’t respond during testing. I set the speed to 0, yet fan 1 continued to operate and respond slightly. My next move is to check how fan 2 behaves now—since it’s not reacting, it seems it can’t detect any signal.
Sure, I can help with that. After taking apart your old card, you can likely skip reapplying thermal paste if you do a thorough clean. Just make sure the surface is clean and dry before installing the new one.
If you don’t have to take off the cold plate from the GPU, the thermal paste should stay put. But if you do need to remove it, you’ll likely need to reapply it. Which model are you working with? Sometimes these devices have fan connectors along the sides, allowing access without taking the whole card apart.
