I want my dad to have a flawless experience noise-wise, so I'm aiming at getting an aftermarket cooler where I'll either go into BIOS and disable the fan completely and remove it and use passive cooling, or set it to only 300-400 RPM with the fan curve and a voltage adapter.

Problem though is that I have no idea where the sweetspot is for this, I don't want to grab something way to overkill and make him waste money, neither pick something performing so bad I might just use the stock cooler.

Any recommendations?
 
To be honest, the Intel stock cooler is pretty quiet by itself. Unless the CPU is under load, you won't be able to hear it most of the time. The stock fan has PWM, which means the motherboard can spin it very slowly to moderate noise. There are certainly many aftermarket coolers that do better, but I would try out the stock cooler first and see if that is adequate.

As far as passive coolers go, it's pretty tough to passively cool a CPU. Even a tiny bit of airflow makes a huge difference, so it gets pretty expensive to go fully passive.
 
I've been looking into the Gammaxx 200T, but 900 RPM minimum is a bit high for my taste, bu I guess I could pair it with a 12V -> 5V adapter to cut down the RPM. If I set the fan to DC and not PWM it should work right?

Also, does anyone know its performance vs the stock fan? Been trying to find info on it vs the stock fan so that I don't waste money on something that isn't good at all, but I haven't found anything.
 
The gammaxx fans are pretty quiet at 900rpm mate in all honesty.

& if you want to run lower rpm than that then go for the gammaxx 300.
The fan is the exact same but the heatsink has about 50% more surface area .
It offers a lot better thermal dissipation because of that.

& yes getting the fan down to 5v will run it at 450-500rpm - although I think that it may require 7v to start the motor on boot (which incidentally is about 900rpm).

Performance vs the stock fan ?? Even at 900rpm it'll knock close to 20c off max temps.
 


900rpm on one fan might be loud.
900rpm on a different fan might be absolutely silent.

I think you're overthinking this.
Get either the Cryorig or the Gammaxx. They will both work admirably.

And you can't really determine until it is in your system, in your case, in your room, listening with your (or dads) ears.
The stock one might even be fine.

And for silence, I hope you're using SSD's. A typical HDD is likely more noticeable than either of those two coolers.

That's a 3470 7 minutes into an Intel burn test load.

985rpm is the lowest I can run it (does say +/- 10%)

Inaudible .
 
Honestly about the same - you are being massively over cautious.
Buy the gammaxx 300 , try it, if it bothers you (it won't by the way though , the psu will be noisier) buy a noctua redux

& swap the fan.

At worst it cost about the same as an evo in total & will be much quieter because it goes all the way down to 400rpm.
