Corsair H115i pro

[Fanatical Meat]

Thoughts guys? Quiet is more important than cool (but cool has value)
I’m freaked out by heavy air coolers and want a water cooled nerd project.
Deepcool AIO coolers look good too mainly because the anti leak thing but per my reading corsairs software is better/easier.
Ideally I’d like to have the pump speed automatically adjust
It would be nice if the fans changed red if running too hot which I think Corsair supports otherwise RGB fans are useless to me.

Are you a human?

Small point / comment. In a liquid-cooled system there are two adjustable items that affect heat removal and hence the internal temperature of the CPU. One is the pump speed, the other is the rad fan speeds.In such a system it is VERY difficult to adjust BOTH of those continuously and automatically, since they interact so closely and have different response times. Without a sophisticated control algorithm, independent control loops for those two will end up "fighting" each other by trying to correct for what the other one did. So almost all such systems do the much simpler algorithm. They keep the pump speed fixed (normally, full speed all the time) and do all the control of CPU internal temperature by changing only the RAD FAN speeds. To some extent you can make a modest change to that if you understand the system. You could intervene and set the pump speed to a different lower speed manually as long as it still is fixed that way, not changing constantly. I expect this would cause the average rad fan speed to increase to maintain the heat removal rate. But as long as the fans can keep up with the removal rate required to maintain the CPU internal temperarture at target, it will still work. Doing it his way would run your pump slower and reduce pump wear over the long term, but it will also limit the max cooling rate, and hence potentially impact the CPU operating temperatures at very high workloads.

Thank you above makes sense, I thought it was weird that pumps didn’t have sensors to just adjust automatically but you have a good point because there is temperature of the cpu, liquid, radiator and fan speeds/pump speed which all add to the complexity. Makes good sense.
What is you opinion on the H115i?

My opinion would be based solely on the specs. I don't have one of those, nor of another competitive product, so I have zero relevant experience. I hope other real users of such can offer opinions. Just a small note of caution: most users love what they have, and have not had the opportunity to make comparisons over the long term for performance and lifetime.

If you're really not 100% sure you want to do an AIO I'd say air is better for silent operation. D15 with a proper fan curve is virtually noiseless. That said I don't think you can go wrong with the 115i.

More of a nerd project, I know decent air coolers are more than adequate and have fewer parts to break.
This is a wants vs needs thing. I want it.

Just put together this https://forums.anandtech.com/threads/680x.2570766/ with a H115i. Quiter at the moment than the D15 and some antec fans it replaced.
