Your link doesn't take me to the cooler...... But, that said, I just installed one of these at work. It went into an older system, with an i5 4th gen processor. They are kinda known for running fairly warm...... Running Prime 95, putting all cores to 100%, temps stayed under 70* C.
My major problem with liquid cooling though, is the coolant seems to mysteriously disappear over time.... and cooler efficiency degrades accordingly. I've seen a couple of these just this week....... Replace the cooler, and all the problems go away. These guys were 4 to 5 years old though..... so, for the money, I suppose it's pretty much worth it. On my machine, I run one of these. Yes, it's huge. But, temps stay stable, regardless of what I am doing, and the fins have a large enough separation, that it doesn't clog up with dust easily. (which is an issue in my 100+ year old farm house.....)
