So the ram, one side has a sticky double sided tape and the other heat pads that are sticky that goes across the ram modules. Memory operates at temperatures that do not need any kind of cooling in a regular pc case. What you see in terms of aesthetics on ram is purely that and carries no performance benefit.
The ram so won't be stencilled yet or anything like that but I have already given one stick a second coat of white and will put the purple details on shortly before the white dries fully. I will show you a before and after once that is done
When im spraying what I normally do is mask up everything near to the edge so everything apart from the areas you want is covered then at the edge you want a fine line 2 or 3mm masking tape, ive run out of the tape that give a nice edge though and don't know when that will show up. I am going to just do the memory with normal run of the mill tape so we shall see what happens.
So to jump an ATX psu to run some fans or whatever like I am in that pic you need to do this:
then turn it on and away you go. Do not do unless you know what you are doing.
