yeah tunix-tx3 is the best value for money..

i did some research when i was looking for thermal paste.
tunix-tx3 was one of the best. i bought one n satisfied.

u can google and compare of all the thermal paste u can find/buy.
then decide

dont worry, none taken.

the higher thermal conductivity, the better it transfer heat between the cpu and heatsink.

for example tuniq tx4 has 6.53w/mk
