Corsair SF600 fan replacement with 92MM Noctua

post #1 of 14
Thread Starter 
Hey guys, just finished this mod to lower the noise of my power supply. To be clear: the fan on the SF600 runs on a wattage-fan voltage curve, so decreasing temperature in the case does not help the fan speed. I believe that my lower-rpm noctua has enough airflow because my case has proper airflow and my ambient temp is usually low (external water cooling).

Here's the exact fan I used:
Noctua NF-A9x14

Pics:



Using the extension cable provided in the Noctua box and the wire from the old fan, I soldered this adapter that allowed me to simply plug in the new fan. After installation and tucking the cable away, the new fan works great. It starts with a higher wattage now, but overall the PSU is much quieter. A success!

The fan in the SF600 is most definitely dependent on PSU temperature, and in fact that is the only thing it depends on. There is a thermistor on the secondary heatsink that helps control the fan speed, and ambient temps as well as power draw (which in turn heats up the PSU) both affect it.

You should still be good though.

This post blows my mind. I have been debating between the SF450 and SF600. I wanted the SF600 for the extra power potential but I was leaning towards the SF450 because it is much quieter based on reviews. I then thought about swapping the fan. I knew it was of the slimmer type so being a Noctua fan boy I immediately looked to the NF-A9x14.

A couple Google searches later, here I am!

How has it been working out for you? I assume it is much quieter? Thanks!

SF600 is quieter at the same wattage drawn compared to the SF450.

Well, would you mind providing me a source for this?

Sorry, quoting you again.

I get why you said this now. Judging by Corsairs website, your statement is 100% true!

However, Iv'e read a few reviews and watched a couple YouTube videos where they specifically say that the SF450 is quieter than the SF600. Talks of the fan curve on the SF600 being too aggressive. I'm starting to wonder if maybe the fan profiles have been tweaked since the review / launch units.

My build is an iTX with a Skylake 65w CPU and a RX 480. Maximum power consumption at full load is under 300w. If the Corsair website is correct, the SF600 will only generate 15db with my system at full load and the SF450 will generate 20db.

I don't know what to think now. Reviewers are stating the opposite of what Corsair is saying.

EDIT: I know the SF450 is plenty for my build, however I don't want to feel restricted upgrading my CPU/GPU down the road.

Aris got a bad unit, I am guessing. Toms' sent it back to Corsair for checking last I heard and JonnyGuru mentioned that the Toms Hardware unit is not indicative of how it is.

These are my results, and they mostly match Corsair's graphs for the SF600:

PM'd you

I believe that my noctua fan has a higher starting voltage, and the fan doesn't spin at medium loads like the original did.
