Can some1 tell me if a Cooler Master V8 GTS would fit in a case H530 Lenovo?

Yes it would fit, but that's not what's important. The Lenovo H530 computers come with 4 different processors with different sockets. The Cooler Master V8 GTS however, works only with the LGA 2011-3 socket, so you have to check which socket your CPU uses.

A custom PC case does not offer a specification of CPU cooler height, and besides which, you would not see the LED's of this cooler with the side panel door in place. The Cooler Master V8 GTX is a tall height. I have to believe that with the narrow computer case just like Dell, HP, Acer, etc of only 6.89 inches wide, a 6.6 inch height CPU cooler Can't FIT with the side door in place and instead sticks out the side of the box without the door panel.
It is mathematically impossible with only 0.29 inches from the bottom of the CPU cooler to the outside of the box at the other side including the circuit board thickness, mount standoff, and metal.

You are either adding it without putting the side panel back on, or rebuild into a much wider case with a side panel window to see it.

There's no cable management in the H530 either. The cables from the power supply interfere with the CPU cooler. I can't see the motherboard parts clearly. You really also need a better power supply and computer case.
