I am have a Dell Inspiron 3520 with a Intel Core i3-2730 CPU. CPU is rectangular in shape.

How should I apply thermal paste? I am already having Cooler Master Mastergel Pro. Can I use this thermal paste?

    does the system use paste or a pad? You can't replace a thermal pad with thermal paste easily. Part of your question is a hardware/purchase recommendation, and is off topic. The rest of it isn't quite so I've edited it accordingly. – Journeyman Geek Dec 7 '17 at 2:16

The recommended approach is to remove the heatsink, clean up the existing gunk by using a cottonswab dipped in iso-propyl alcohol and place a small pea drop at the centre of the processor.

Once the heatsink is mounted, the pressure of the mount should spread it evenly across the processor.

This is how much I had applied for my i5-3470

Note that CoolerMaster recommends spreading the gel across the CPU evenly with the spreader but in my experience that causes more problems and it's easier to just put a drop and let the heatsink do the job.
