Is this normal? My VRAM has 2 different tempertures

It's fine.

VRM1 may refer to the VRM which powers the actual GPU chip, and VRM2 may refer to the VRM which produces the power for the memory chips.

Often it's a single VRM controller (chip) which can be configured in a specific configuration, like for example 6+1 phases - the 6 phases produce the power for the gpu chip, and the single phase produces power for the ram chips.

 

RAM chips typically consume little power, let's say 10-20 watts maximum, so it's only natural that the chips which form that single phase would heat less to produce those 10w

The gpu chip can consume 120-150 watts, which is split across several phases... in my bogus example of 5 phases, each phase would produce 30 watts. as those 5 phases are also closely packed together, the heat produced by all those 5 phases is more concentrated, so it's natural that those phases will heat a bit more and will not cool as fast... therefore the average temperature will be higher.

The actual chips that form those phases are designed to work up to 125 degrees celsius, but manufacturers usually do their best to keep the temperatures below 100 degrees Celsius, because above around 105-110c degrees the circuit board material can be damaged over time.

 

As for the GPU chip itself, the RX 5xx series chips are designed to handle up to around 90 degrees Celsius, and most RX 580 cards have their BIOSes configured to automatically adjust the fan speeds to keep video card as quiet as possible while keeping temperature below around 70-75 degrees Celsius. 65-75 degrees Celsius for the GPU chip is perfectly fine temperature, safe, it's ok for long term use of the video card.

But if you want, you can go in the control center AMD makes and adjust the fan curve so that the fan will run at faster speeds and keep the card cooler. There won't be any benefit just your piece of mind that the card is cooler.

My graphic card is Maxsun RX580 2304SP with 8G VRM

The complex charactor in the picture means “celsius degrees”  or C.

Under 90% situation, GPU VRM1 is always much more hotter than GPU VRM2, is this normal?

I was playing fortnite and GPU VRM1 is 79degrees but GPU VRM2 is 30 degrees, and the cooling fan was running at 100% speed

The temperatures are fine,

but i am not sure if the fan speed is normal for this graphics card.

so..i dont have to worry about the tempreture difference between VRM1 and VRM2?

Not at all,It's all fine :D
