Some GPU come with a very aggressive fan profile. Since all modern browser use GPU to accelerate.

Control Fan Speed Macbook Pro Bootcamp Macs Fan Control - control fans of any Mac & Boot Camp! Kris Ivan How to control fan. There is a way you can control your fan's speed and power to prevent this from to choose the 'Macs.
When you scrolling up and down, the GPU and the associated VRAM actually work a bit harder than 'just display something (2D idle)'. 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'. Therefore, you will able to hear the fan on and off. In fact, if the demand is bigger, and make the fan keep spinning at a faster RPM, you may not notice it at all. But when the noise signature keep changing, it's very easy to catch your attention. One of the easy test is browning Facebook.
It's quite demanding (as a webpage), and can use lots of VRAM. Also, you can keep scroll down forever (particular useful for this test). If you can hear the fan spin up and down when browsing in Firefox. Then I am quite sure there is no solution in MacOS apart from flashing your card (with a more gentle fan profile). Anyway, you may still try to stress the card a bit after boot to desktop. Luxmark for 10 seconds is good enough.
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 before stress test (e.g. Using Firefox), then try to stress it for few seconds and do the test again. If no more fan noise, then it means your card need something to stress it EVERYTIME after you boot to desktop. Otherwise, it won't work properly. But if the fan still spin up and down after stress test.
Then I am 99.99% sure flash it is the only way to fix it. Some GPU come with a very aggressive fan profile. Since all modern browser use GPU to accelerate. When you scrolling up and down, the GPU and the associated VRAM actually work a bit harder than 'just display something (2D idle)'.

Click to expand.I just bought a Sonnet Breakaway eGPU and MSI RX 580 OC and it's already driving me nuts just using the web browser or Visual Studio Code; the fans spin up briefly every time I scroll. It makes me wonder about the long-term durability of this setup with MacOS, at least for the GPU fans. There's no way to adjust the fan speed with Macs Fan Control. Edit: Nevermind, this setup spanks the integrated GPU in the early 2015 13' MBP so hard, there's no going back. The CPU runs much cooler now in clamshell mode when driving two monitors.
Getting 60+ fps on Shadow Warrior at 2560x1440, and I can work on Unity and Web projects smoothly in 4k now. Been using an Apple TB2-3 connector and it's been flawless with 10.13.3.
Macs Fan Control allows you to monitor and control almost any aspect of your computer's fans, with support for controlling fan speed, temperature sensors pane, menu-bar icon, and autostart with system option. Software solution to noise problems such as those caused by iMac HDD replacement, or overheating problems like those found on a MacBook Pro.
Set any constant value to any fan (e.g., minimum). Control fan speed in relation to a temperature sensor (e.g., 3rd party HDD).

Macs Fan Control worked beautifully with High Sierra and Snow Leopard (dual-boot disk). The app lets you monitor the temperature of all sensors (MBP 6.2 has 12) and then control the fan speeds. The app allowed me to discover that the GPU diode temp sensor was only working intermittently, which likely explains why the SMC stopped controlling the fans. Now I can control each fan independently with a working sensor of your choosing or set them manually. The app also lets you revert to auto mode, which returns control to the SMC, which is of no use in my case. On a side-note, I also found that replacing the thermal grease on the GPU and CPUs helped a lot (used Arctic MX-4).
