So as you said the only difference about ml240 and the 240 is that the one have rgb and the other no is better to take the one that is less money right ? So as i said in my country here is the RGB version and something else the kraken x62 is more money so if i give more money is not better performance??? And better quality liquid cooler ??If you mean Masterliquid 240, they'll all do good job even with best OC. I prefer Cooler Master for easy mounting and connections.
For the best performance oc and temperature kraken is better from ml240 ?If it was some hotter running CPU, there may be some difference between all coolers with similar configuration but my old 1700x and now 2700x are just fine even with my CM Nepton 140XL (Single radiator) even at full OC:
