Hi i was looking for a cpu cooler, preferably liquid cooling, for my i7-4790k and my case is a haf x. Any good ideas? Thanks in advance
Liquid cooling is worth it if you wish to OC and get the most from your processor, which you obviously don't.
You can learn how to OC from the many articles and guides here on the Forum.
If your temps are at 80C consistently then degradation of the CPU will happen over time.
If your case will fit one, then get an AIO liquid cooler. There are many choices.
