Found 11th May
About £5 cheaper than anywhere else, been looking around and they seem to be a little scarce, marked as end of life on Scan..

From the same seller as the recent Steelseries Rival 500 mouse deal, saw that and found the seller on ebay as well as Amazon. Arrived very quickly, no issues. The mouse was brand new, and I'm really liking it.

Decided to try and seek a couple of these out to potentially replace the Noctua NF-A15 fans on my D15s, as they suffer from some vibration and slight resonance issues. I think the HP-14 fans should be a reasonable substitute to them, as they have interchangeable corners that can allow for mounting into either 120mm or 140mm positions, and the D15s uses wires spaced for 120mm sizes to mount the fans.

I also happen to really like Fractal's fans generally, being a quiet freak I appreciate the very neutral tone of them, just a little low wind turbulence and none of those mid-high frequency tones that bother me so much. I have the 120mm version of these mounted on my Raijintek Morpheus II GPU cooler, and have been performing excellently, very quiet indeed and pushing air through the chunky heatsink very effectively.

Ah good spot. I guess you've got a little more protection going through ebay in theory, but there was no issues with that mouse I bought, and they seem to be well rated so that's a solid option too. Great if you wanted to kit out a bunch of radiators nice fans or something.
You can get the Corsair ML140 for about this price on amazon (if you buy a 2 pack). better fans than the fractal imho

Having used both the Corsair ML and Noctua fans for a little while, I find they're both prone to the odd resonant hum at certain RPM speeds. But with all the Fractal fans I've used I've never really come across that issue, they've a very consistent low tone generally. Also worth considering that the dual pack of ML140s is a little barebones; the Venturi comes with the interchangeable rubber corners that help to dampen any vibration into the case, plus a little y splitter cable (can't recall if the ML came with one of those). Also the Corsair fans are £23.49 for two (EDIT: oh there's two listings I've seen on Amazon, still a little more though), which is a little more than these. For maximum cooling, if you don't care about noise and just want the most airflow possible the Corsairs do have a very high max RPM though, something to consider.

The Corsair fan blade design is similar to the Noctua NF-A14, in that they are both a kind of general purpose fan, in between airflow and static pressure. For a front intake fan that might have to pull air through some dust filtration or other mesh they work very well, but for placement on a cooler heatsink or radiator the larger pressure optimised blades of the HP-14 should perform a little better. I swapped out the two ML120 fans that were on my Raijintek Morpheus II to a couple of the HP-12, and I think it was a noticeable improvement in noise and cooling capability and lower RPMs.

Between the Corsair ML140 and Noctua NF-A14 I would recommend the ML140, less noise issues overall from my time using them. I have found that the ML series does seem to need a bit of breaking in at first before come noises go away for whatever reason, probably due to the unusual bearing design. An ML120 used to make rather loud 'chirping' noises at low speeds for a while, but that just went away one day. And I think it's similar with the ML140, I'm currently using one of mine as a front intake as the air turbulence pattern seemed to interact a little better with some of the mounting apparatus in the front part of the case. Working well and is decently quiet for now.

For most people all of these are good options I think

At the cost of noise you can get the best performance if you use Thermalright TY-143 . I was lucky enough to get couple of this fans for £7 each from amazon sometime ago. At low rpm they push enough air staying very quiet and at high rpm airflow is much higher than 99% other fans on the market.They also have very high air pressure.
Cool, good to know there's another option for max performance

The 2x Fractal Venturi HP-14 fans I ordered arrived today, just got them hooked up in my system. Initial results seem excellent! Very good performance on the D15s, certainly no worse than the NF-A15s that were on there previously. Even though they supposedly have a 1cm lower diameter the greater static pressure design of the blades does seem to be making up for it. I'll have to see how they do over the coming days, but so far I've not noticed any real resonance or vibration issues. Doing a flat-out Blender render and the 2700x 8 core CPU is holding around 65c, middle fan is 670 and the front fan is 600 RPM (running fans at different speeds is a little trick to reduce potential resonance from constructive interference), and that's under half the max speed they can do, so plenty of headroom. I am running a -0.075 undervolt on the CPU though, to reduce temps further.

Will report back if there's any issues, but Fractal really seem to make some kickass fans. Recommended.

I would be interested to know if temps/noise were better or worse as I am looking for replacement fans for my D15 due to hating the colour scheme like so many others, these could be perfect if they perform on par or better than the stock fans.

That might give an idea of how they look, apologies for the poor picture. I haven't done any proper scientific testing back to back with these and the stock Noctua fans, but so far I would say that they are at least on par if not better in cooling performance, and better in terms of noise, certainly less low vibrations being transmitted through the heatsink. I don't care about looks at all, I just want things to perform well and be quiet, so I couldn't say whether I think it looks any better like that.

It's not too surprising if they perform a little better than the NF-A15 fans I think, both the heatsink towers are rather thick, so having a good amount of static pressure from the fan will help to push air through more effectively at lower RPMs.

Very pleased so far, your mileage may vary of course. But at that price I would say go for it

They're Okay replacements on the D-15 if you don't mind performance drops and higher temps.

I wouldn't recommend for overclocking or anything as I tested these out and had a good 3-6c increase with these fans over the stock ones, and as my temps are already high I can't really use as replacements. Looks like I might have to stump up the cash for the Chromax ones if I want black fans.
Edited by: "MisterFresh1980" 15th May
Err I haven't seen any performance drops or higher temps with these, did you compare them at the same RPM? Mine never really have to get over 700 RPM, the Noctua fans would be the same or slightly higher speeds but a little more noise. They have the same max RPM as the A15 fans, lower airflow probably but higher static pressure which definitely helps with a fat fin stack.

I guess your use case must be much different to mine, maybe pushing at the limit of the cooler? In that case I would certainly try and lower the voltage, or settle for a lower overclock if it's that crazy. But I don't know what CPU you're trying to cool there.

Yeah I might try again and do some better testing later before and after to see if I can get some more reliable numbers I can't see why they wouldn't perform similarly unless the airflow is a factor, the fans look good and are well made and are quieter than the Noctua ones so would be good to use. It's an Intel 8700K at 5ghz and it gets fairly hot! May have to delid although never done that before and wasn't keen but I have heard it can really improve temps.
Ah yeah, the 8700k does get mighty hot no matter the cooling unless it's delidded. The thermal paste under the IHS is certainly the limiting factor, JayzTwoCents did a video recently with a 4x 480mm radiator loop - youtu.be/Q2S…5
The GPU was like 5 degrees above ambient under load, while the 8700K was still getting to the mid 80s....

It could be that if you are having to max out the fans to keep the chip cool at full load (seems likely), then perhaps the greater airflow might win out, while at low RPMs perhaps the Venturis would do better. I might do some more scientific testing myself just to be sure, I've got a 2700x which is soldered, so should show pretty well how good the cooling is. I'll probably set it to 4.2GHz, 1.4 volts and 800 RPM for each set of fans, and see how well they can do.

I've experienced similar issues with the Coolermaster Fans, a certain speed will produce vibrations that are not correctable. You can 'tap' the fan to stop the vibration, but no amount of rubber stops it.

Fractal fans all the way, good noise (basically none) and all you hear is the air moving.
My case came with a couple of fractal GP-14 fans, one of which makes this annoying ticking noise (albeit not that noticeable). I also didn't think the airflow was amazing.


So I spent a small fortune on two of the much hyped Noctua fans; NF-A14 PWMs. What can I say? The packaging is wonderful and gives a very 'premium' feel, however they make an incredibly annoying hum / resonating sound in a certain RPM range. A google search showed I was not the only one experiencing this. Unfortunately that RPM range just so happens to be around where I would have liked to run them for optimal air flow! Any faster is too much (and just plain noisy) and any slower is not enough. So I went back to the fractal fans, the slight ticking is far less annoying than the droan from the Nocutas.

If these HP14s are similar to the GP-14s I have then they are a good buy at < half the price of a Noctua.

I also have some Nanoxia 120mm PWM Deep Silence (650 - 1500 rpm) fans which are excellent. But I can't vouch for their 140mm versions.

TLDR: I found Noctua expensive and over rated.
Edited by: "Cov1986" 16th May
Yup, exactly my findings; Noctua is quite a bit overhyped IMO. I have noticed very slight ticking from Fractal fans, but only when you put your ear close to them, completely not audible in a standard closed case. Most fans have a slight tick to them actually, I guess down to the way the motor switches to keep it spinning or something. Hums and resonant tones are way more irritating.

The GP-14s are solid fans, I suspect if they came with the case then they are the standard version, there's another version with X2 in the name that has the same bearing as the Venturi fans; "High grade LLS bearing with class leading 100,000 hours MTBF". Have a slightly quieter sound, though both are great.

Great video just shows how how hot the 8700K is though.

Right so I have extensively tested and the difference in my set up between the orig Noctua fans and these is about 3 degress cooler with original fans, but I am running at max benchmarks here and this is my fans on pwm running pretty much full., and cpu at 5GHZ on all cores no avx offsets with 1.34 adaptive voltage applied.

So heavy bench marking

89 degrees max with Fractal fans
86 with Noctua and lower averages

So not a massive difference but when your nearly 90 degrees because Intel decided it was okay to continue with their terrible thermal options on the 8700K even though it has more cores and threads it is a enough for me for need that 3 degrees drop.

I actually believe my 8700K temps have got worse from when it was new, like the CPU itself can't be cooled as well now as it could when I first got it so hoping it's the crap underneath making bad contact.

So I have been brave and ordered a de-lid kit and Thermal Grizzly conductonaut to attempt my first de-lid and void my warranty on my expensive £300 processor because temps just aren't acceptable. Hopefully once delided I would have much better temps and be able to use these fans without a second thought or worry about a 3 degrees difference.
Edited by: "MisterFresh1980" 16th May
Interesting, yeah I guess when you're needing to run at that max RPM to keep it cool the greater airflow at that speed would surpass the need for high pressure. Did you also check the ambient temperature between the two? Can make a big difference to results, though a little tricky to check for accurately.

From a Kitguru article testing airflow vs static pressure fans - "I would suspect at a lower fan speed, the static pressure models would open up a bigger performance gap between their airflow counterparts as they can push air at a higher pressure. It is likely that at 50% fan speed, the airflow fans are still capable of pushing enough air to cool the heatsink/radiator, but this may not be the case at a lower rpm."

That's just a supposition though, I'll have to test it out with my system when I get time. I'll probably try something like 500/800/1100 RPM testing between the Fractal and Noctua fans, at a fixed frequency and voltage. Just anecdotally I think the Fractal fans are working out better for me just now, noise is pretty low for sure.

The thermal paste thing is really annoying, why I'll be sticking with AMD until Intel can sort it out.

What benchmark software are you using? Some of them, like Prime95, generate unrealistic levels of load and heat.

Mine is delidded and I use a big air cooler @ 5GHz 1.33v. I have a fractal case which is fairly restrictive but have 4 intake fans. I see an average of 81c with peaks into the high 80s with Prime95. In my view something like AIDA64 is more representative and generates lower temps. In my actual day to day use including gaming I peak in the high 70s but the average is much lower.

The 8700k just runs too hot. I got 100c peaks on stress benchmarks prior to delidding and often saw averages in the 80s when gaming... madness.

I think I may try getting an AIO water cooler to see if that improves things. If nothing else it would be nice to get rid of the huge space hogging heat sink that makes it impossible to do anything to the mobo without removing and reseating the cooler each time.

Was using the latest Realbench to benchmark seems to stress it high enough to test out cooling quite well, uses avx but not as bad the others. If I use AIDA64 without avx I am fine but with avx can get spikes in the mid to high 90s

Yeah ambient was spot on the same both times, I ran it a few times as I was so hoping the fans to perform on par.
Well I thought I would report my de lid temp results - quite a ridiculous temp difference that I didn't expect at all, finally got the guts and time to do it this morning and I am shocked at the results I have got a 20 degrees temp drop so benchmarks that was causing 85 temps are now 65, 90s temps are now 70s I am so happy I did it.

After 6 full runs of realbench where I used to get hot up to 90c and my cpu fans were loud as hell I got a max of 65 degrees and cant hear the cpu fans which is an insane difference.
