Replace Kraken X41/x61 Fans with Phanteks PH-140SP?

post #1 of 11
Thread Starter 
I have some PH-140SP fans lying around and was wondering if it would be worth (better temps) mounting them on my x41 and x61, replacing the stock NZXT fans? I primarily want lower noise but don't want to sacrifice performance.

Side questions: I have a H440 case with a x41 in the rear and x61 on the top both as exhaust. Would it be better to have 3x 120mm intake fans or 2x 140mm intake fans? I again have the stock NZXT 120mm fans that came with the H440 and some spare PH-140SP.

Yes, i guess changing the stock fans with kinda quality fans (assuming the Phantkes models kinda have the same caracteristics) could help

I've had the NZXT H440 and also both the X41 and X61. Lets start with the case.

The NZXT H440 has slightly obstructed airflow, although the renewed H440 has better airflow.
I assume you have the normal model? The new H440 was released like 1 or 2 months ago.

In terms of 3 120mm fans or 2 140mm fans: I personally prefer 2 140mm fans for lower noise.
The 3 120mm fans will generate a bit more airflow and might cause a 1 or 2 degree temp difference, but it won't matter too much in terms of cooling.
I do prefer 2 SP fans in the front because the case is slightly obstructed and SP fans can really push the air through.
Of course airflow fans are great too and it really doesnt matter temp wise.

Honestly it doesn't matter that much, i just preferred 140mm fans as they are quieter but will perform slightly less in terms of overall airflow.

Now for the X41 and X61: the fans NZXT provides are really noisy, and i mean seriously noisy like a vacuum-cleaner.
They sound okay up to about 35% rpm, but at 100% they generate like 43 db of sound.

I would seriously consider replacing them with decent aftermarket fans; the phanteks are alright but something nicer would be great.
Perhaps some corsair SP fans as they are fairly quiet and deliver nice static pressure. In my country they also come as duo packs often which makes them affordable as well. But the Phanteks fans will generate a lot less noise compared to the stock NZXT fans

But in general: The NZXT H440 is a quiet case, but not the best in terms of airflow and cooling.
A friend of mine once replaced all of his NZXT fans with Noctuas (120 + 140mm fans) and had like a 1 degree temp difference which was a actually within the margin of error.

Could you detail me how the pump sounds ? (noreport pls, no hijack)

Hmm corsair fans have good 'tested values' but actually worse in real life:

The pump on both the X41 and X61 I had were making some pretty annoying noises.
I had an annoying rattle sound in both pumps and I literally tried everything in terms of fan headers and testing at what RPM the pump sounded best.
On the cpu_opt fan header, the one that always operated at 100% for pumps, it rattled like hell; this was audible with closed case.

I RMAd the X61 and got another rattle pump. Needlessly to say I will never purchase an AIO cooler ever again.
Oh I also had the Corsair H110i GT which was slightly better, but still had pretty noisy pump. I must say I'm also really sensitive to high pitched sounds coming from TVs, pc monitors and also pumps.

That's true, it was just an example smile.gif I've had Corsair 140SP and 140AF fans and they perform fairly good I must say.
I didn't really experience any real buzzing, but I usually run my fans at around 500-650 RPM max as I prefer silence of extreme cooling.
I'm now a massive Noctua NF-A14 fan fanboy (heuheu) as they are really, really silent at ~550 rpm.

It is quieter, but then again the NZXT H440 case is already really silent with all the heavy padding and lack of ventilation holes.
The NZXT H440 is build to be compact and also silent. If you really love low temperatures, the NZXT H440 is just not the correct case to buy.
You can spend 100 bucks on Noctua fans and it still won't be as cool as you'd probably like. You're better off buying a new case with that money that is meant to have great, unrestricted airflow.

maybe you could have asked for a few last RAMs, the nzxt X series is said to have some of the quietest cheap AIOs (excluding x31) when not faulty lol
what case setup did you use with the pump (push/pull ? top ? back ? front ?)

yeah right, i guess most 140mm- fans are quiet at such low speeds, maybe one day test the TY-147A a higher RPMs, i too don't really like noise and i felt like this was always whisper quiet no matter how high i cranked it.

I dunno man, OP said the fans were noisy, maybe better dba/airflow fans can help

Haha I was pretty fed up with all the RMAs. I was an early adopter though, bought it the second it came out.
There were quite a lot of people with the same pump noise at the time.

I used about all configs to experiment: top mount (exhaust) & front mount (intake) with push, pull and push/pull.
Basically it barely matter where you mount it, even in the front as intake. You'd expect the rad + fans to throw all the hot dissipated air into the case but temperature wise it really didn't matter.
Even the GPU didn't suffer from it.

I might just test them one day, but i'm really happy with the noctuas right now. Great quality, 6 year warranty and loads of goodies (extension cables, 7v, splitter.. Insane packaging really).
I switched to a custom loop like a year ago so no more AIOs for me, im all set thumb.gif

Thanks for the answers, appreciated.
IMO the difference werent so big between rad position as maybe you used the fan so slowly than it didnt maka a diff lol.

I wonder what the reference fan SPCR used to that outperformed NZXT's fans on the x61.

Here is my current airflow setup:

A friend of mine once replaced all of his NZXT fans with Noctuas (120 + 140mm fans) and had like a 1 degree temp difference which was a actually within the margin of error.

I have the older H440 model. The ventilation looks the same though compared to the old and new edition.

From your post, it seem like changing the fans will not affect performance much if at all (margin of error). If that's the case, I'll just optimize for noise then. Btw, I actually had the H110i GT and the Corsair fans it came with were VERY loud. In addition to that and the wonky Corsair Link performance, I had to return it and got the x61. I'm still waiting on that to come in but I have an x41 right now and it's pump is MUCH quieter than the H110i GT. I can run it at 70% without hearing it. At higher speeds, a slight hum noise is heard but will be drowned out with background/game noise.

That is your best course of action. The reasoning is actually pretty simple, and is why there is no magic fan for CLCs. To start, you have a very inefficient radiator specifically designed to work with higher rpm (and output) fans. After all, higher speed fans are significantly less expensive for the mfg than using a more effective rad material than aluminum. With that being the case, you essentially need to put the same amount of air through the rad to get the same level of performance, regardless of what fan is being used to push the air through. Since it is a very high fpi rad, most of the noise comes from the air passing through the rad - not from the fan, itself. As a result, it is very difficult to increase performance and lower noise simultaneously.

I hope that makes sense.
