They are not designed to be cooler fans and will not perform as well as stock fans do.

*Their spec for static pressure is only 0.9mmH2O. I want that much or more for my case fans and more like twice that for cooler fans. Remember static pressure is H2O measurement when the air stops moving.
*I also find it hard to believe their spec of 98cfm @ 1000rpm for a 15mm thick fan. .
* The top 140mm fans (25mm thick) push high 80s cfm @ 1300-1500rpm.
Same goes for their 9-18dBA spec.

Could you give me a link to the source of your temperature graph please?
I would like to see what their test proceedure was.

The performance specs on their site and that graph don't add up.
Their website specs shows this 15mm thick fan having fairly low static pressure, low noise and CFM way above normal. for 25mm thick fans.. even at much higher rpm.
The graph shows a 15mm thick 140mm fan with performance way above normal for 25mm thick 140mm fans at 1000rpm

Sorry, but I'm finding it very hard to believe it's as good as they are claiming.

Why do Caseking.de bundle them with a Megahalems then?

http://www.caseking.de/shop/catalog/Prolimatech-Blue-Series-Megahalems-Dual-Ultra-Sleek-Vortex-Edition::21642.html

And I'm not looking for better performance. My 2x P14 on my Noctua is NOT PWN and run 5v all the time. I'm looking to change these with BLACK PWM fans (because of looks) and under load i dont mind the fans to ramp up.

They look awesome and even if they are only 15mm, they must perform better at 12v than my P14's at 5v..?

I just got tired of Noctua colors ruining my theme

They are good fans, but i want black fans now. Changed all my casefans too.. Only the 2 CPU fans left! I'm open for suggestions for PWM fans that fit on NH-D14

You could also look at the Scythe SlipsStream/GlideStream and the EKL Alpenföhn WingBoost2 fans. If you dont mind the white blades, the Thermalright TY.-147 would be a good and cheap option.

But why dont you just buy the Prolimatech USVs and compare them to stock fans and write little review, so we all van learn a little more about them

Thanks for the link Elohim
I can not see any way this Prolimatech 140mm 15mm thick fan @ 1000rpm will outperform the best 140mm 25mm thick fans on the market. Granted it has more blade to help help with blade surface area.. but it's running 200-500rpm slower than most others.

No idea. Maybe because that's what Prolimatech supplied them at the best price?
Notice they are running push/pull.. this helps overcome low static pressure and helps keep airflow through the cooler. On NH-D14 you can do this on only one tower and will have a 10mm gap between fan and other tower in the middle.

Going with PWM fans is a good step forward. They are all I run now.

Very possible but you could run your P14's at 12v too.

And now we get to the meat of your reasoning. You want something that looks nicer.

I agree with Elohim and lugal; look at some other black fans.

And you can control PWM case fan speed very easily by using a PWM splitter with molex socket.. and case fans will run same speed as cooler fans if they are same rpm range fans.

Well guys, I hate eating crow but have to admit the more I find out the more I like what I'm seeing with these Prolimatech Ultra Sleek Vortex. Although there isn't a lot of info about them I'm not finding anything negative and the below data is impressive. Still want to try them to see if they backup the data.

Another review http://www.technews.lt/naujiena/n/a/prolimatech_ultra_sleek_vortex_14.html



and another
http://dvtests.com/?p=12514

* 120m3/h ~70CFM
Test at 5V:

At the first test conducted at 5V the fans provided average airflow level of 64.8 cubic metres per hour at average 660 revolutions per minute. At these revolutions per minute the fans were absolutely silent.

Test at 7V:

After I increased to 7V the fans reached maximum 855 revolutions per minute and remained silent while providing average 85.92 cubic metres per hour. Really impressive to be honest.

Test at 9V:

The third test conducted at 9V and the fans were rotating with maximum 990 revolutions per minute with airflow level of 100.32 cubic metres per hour. At this test there was a tiny noise from the air passing through the propellers. There was no noise coming out from the motors.

Test at 12V:

The last test done at 12V and revealed the full capabilities of the products with average airflow level of 120.48 cubic metres per hour working at only 1140 revolutions per minute. The noise from the air passing through the propellers increased just a little bit.

& OCN http://www.overclock.net/t/1411249/review-comparison-prolimatech-ultra-sleek-vortex-14-vs-scythe-gt-ap-15

Thinking of buying one as a side exhaust (the blade design is basically that of an exhaust, after all) but it's sometimes cited as noisy (no idea since it's 1000RPM max) even if it performs well and looks nice. It's a shame it is $20 (+shipping in some cases).

THx for the links AlphaC. But tbh the fan speed is really not all that interesting, especially if you compare such different fan designs. The USV obviously pushes more air at relatively low rpm due to havin 17 blades instead of only 7, but that also produces more noise at that speed...

Nontheless it seems to be a decent fan especially if one needs a slim fan.
 
#22 ·
Definitely a good fan. At first I didn't believe it was as good as it is but these reviews definitely prove it performs very well.

Thanks AlphaC

A friend borrowed me one to test was planning on MK-26 + dual vortex 140, pretty decent fan for its thickness, very quiet at its lowest rpm, but my GTX780 cant control them with the included Y splitter/adapter from Prolimatech. I did manage to test it on FanXpert2 in case someone is interested on its PWM range of operation

 
#25 ·
Apropos OP's question (no longer active, I know) I would recommend an NF-A15 PWM for the middle fan of an NH-D14. The NF-P12 seems to be the best front fan. It is now available as PWM, which I also recommend.
