![]() SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). Then I am 99.99% sure flash it is the only way to fix it. SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. Otherwise, it won't work properly.īut if the fan still spin up and down after stress test. If no more fan noise, then it means your card need something to stress it EVERYTIME after you boot to desktop. using Firefox), then try to stress it for few seconds and do the test again. If you can hear the fan spin up before stress test (e.g. Just in case the power control bug not just affect the PCIe & PSU fan, but also make your card unable to correctly stay at low power mode.

If you can hear the fan spin up and down when browsing in Firefox. Also, you can keep scroll down forever (particular useful for this test). It's quite demanding (as a webpage), and can use lots of VRAM. One of the easy test is browning Facebook. If the fans turn on, the problem then is located in the Power Supply Unit (PSU) of the original Laptop or Desktop. To verify if the problem with the fans resides in the power supply, one effective test is to connect the motherboard (That includes the GPU) to another power source. But when the noise signature keep changing, it's very easy to catch your attention. Test Number Two: Checking the Power Supply. In fact, if the demand is bigger, and make the fan keep spinning at a faster RPM, you may not notice it at all. Therefore, you will able to hear the fan on and off. In some case, it's just strong enough to trigger the fan to spin up (keep jumping above and below the "fan spin up threshold". When you scrolling up and down, the GPU and the associated VRAM actually work a bit harder than "just display something (2D idle)". Since all modern browser use GPU to accelerate. ![]() ![]() Some GPU come with a very aggressive fan profile.
