In Need of a CPU Cooler

[Pritam2K17]

Hey I'm from India...I have AMD FX 6300 and it is on stock CPU cooler..But IDK why(Maybe because i'm using a cheap thermal paste) my CPU temp is 50'C in BIOS!
I have a 120mm Fan beside the CPU cooler(attached in cabinet), so u can tell me any liquid coolers also..but i have 155mm CPU cooler height restriction(For Air coolers) in mah cabinet...
Thanks in advance.
