Built my first PC 3 ish weeks ago. I noticed right from the start that there's a weird rev sound like if an engine started in a car. It's not very loud, it's just short bursts.
Looked into my case, and noticed that my gpu fans sometimes stop spinning, and when they did spin, they did it in bursts.
Is this normal? Should I be worried?
Thanks.

A lot of graphics cards will have their fans stop spinning when the card is below a certain temperature to preserve fan life, usually around 50 C. This means that if the card is under just enough use to keep it around that temperature, it will heat up enough to turn the fans on, which cools it down almost immediately. So yes, this is the correct operation.
That said, there are a few things you can do about it, since I know it can be pretty annoying. You can let your computer idle the GPU lower, a lower frequency will mean less power draw and less heat. This could be done through a overclocking utility, or through nvidia's control panel, as it won't underclock if it's set at "maximum performance" on the power settings. Through the overclocking utility, the fan curve can also be set to activate at a different temperature, or hysteresis can be added, which could lead to the fans turning on for longer periods of times, but less frequently.
Set a custom fan curve (stepped, double click on the graph so it's digital) and enter a hysteresis value.
What gpu?
2070 Gigabyte
Thats been known to do that. Return it if possible
Is this very bad..? Others tell me that the GPU slows down fans when it’s cool enough.
To add to this, in CSGO, when I’m REPLAYING a demo ( Tasking on my PC because CS demos are terrible ), it does it only when the demo is playing and not while paused.
Not really. You should prolly just set a custom fan curve, and shouldn’t face many problems. However, I would recommend EVGA next time over gigabyte. For one gigabytes warranty is non transferrable, and makes reselling a bit harder. EVGA is also renowned on their cs as well
Is this during heavy gaming sessions or just idle / light tasks? Alot of new GPUs don't turn on their fans till they hit a certain heat temperature. Your GPU may be reaching the auto turn on fan temperature and then turning them off once it cools down below said temperature then repeating the auto turn on after a while.
