static pressure fans thst are better than the Arctic PWM pst fans ?

I have the cooler master masterliquid 240 Lite and i like it, i use Arctic P12 PWM pst fans and they are really good

I wanted to have more cooling power for my ryzen 7 2700x (im gonna change to a ryzen 4000), so i bought 2 Noctua NF-F12 PWM fans.

A couple of thing i can say about the noctua fans they are very expensive and somehow more noisy, since i can hear some noise i didn't hear with the arctic p12 pwm pst fans, mostly above low speed 900-1000rpm or higher but also general i feel the fans are not as silent as the arctic P12 fans, even at 1800rpm the arctic fans are more silent than the nocuta at 1500rpm

The 2 i used are now used as case fans together with arctic p14 pwm fans

Now to my big question, which static pressure fans are better than the Arctic PWM pst fans and with no hum,high pitched noise, what so ever, i don't want to buy Notcua NF-A12x25 fans, i think they are way to expensive

There isnt any, other than the nf a12x25. The p12 are the next best thing after them. The p12s are almost as good as a12x25, despite price difference, brand and ppl being skeptical about them.

Watch this after min 11:40

A12x25, and GTs are the only fans I'd rank as top tier.




Not sure about the noiseblocker eloop though.






Want to try the P12 tbh. I wish they sell the P12 CO (double ball) in packs of 3 or 5 though :[

Eloops are a bit on the noisy side compared to them. And i do agree with you.

They are very similar in performance, because they are very similar in design.

The A12x25 it's literally a copy of the GT and the p12 emulates that very well with less blades.

buy a better cooler not faster noiser fans.

Issue is P12 looks like it's made from cheap plastic from the pictures, I haven't had the time to buy one and test myself though.




At what application does the NB Eloop beat the GT and A12x25? Video shows that the directional air is straight / uniform instead of most fans dispersing the airflow over wider area. Though I don't think this would matter much on a radiator or case fan use where all slots are filled (ie: if panel can support 3 fans, we populate all).

NF-A12x25 are one of the very best, but also very expensive. While their impeller looks similar to GT, it is definitley not the same impeller. Noctua spent several years developing NF-A12x25 impeller getting an impeller with very close clearance to housing and minding a material that didn't stretch / expand out as rpm increased and rub on housing.

What are your 2700x temps? Even better what were they with P12 at same speed / noise level as NF-F12? I ask because results is a good comparsion test to gain knowledge of Arctic P fan performance, noise levels, etc. Do you per-chance have a sound meter?

If you can't keep CPU cool enough with these fans the problem is probably not the fans, but your CLC. CLC use the cheapest possilbe waterblocks and cheapest possible pumps with no publish specs. So we have no idea what their flow and lift (pressure) ratings are. Almost all fans have pressure and flowrate in their specs, but there are only a couple CLCs that publish this information. Indepenent testing has found they flow about 40-60L/h, about the same flow as health adult urinates. By comparison AIOs like be quiet! Silent Loop, Aisbaer AIOs use an Alphacool DC-LT pump rated 100L/h and up to 0.6m H2O lift. Swiftech H220 pump is rate 1050L/h and 4.4m H2O lift, and new Drive X3 pump is rated 660L/h and 2.8m H2O lift. Most popular custom loop pump, the D5, is rated up to 1500L/h and up to 3.9m H2O lift.

Long story short, your problem could easily be your CLC can't draw heat away from CPU fast enough and/or can't move that heated water to radiator fast enough.

I completely agree with this and recommend the same.

Did we pass into an alternate universe?

Yeah....the little girl hentai avatar is really creeping me out....

Im gonna return the cpu tomorrow.

I get at 4.0ghz around 85-90c and mosfet can go as high as 100 c or more, 200 or more watt being used in different stress test

Stock it only boost up to 3850mhz, that's why i tried 3.9,4.0 and 4.1ghz but also beaoce my goal was above 3.9ghz

I considered an air cooler to get more airflow around the vrm and mosfet but thought it would make more sense to go for a ryzen 3600 since i has an adequate cooler for that cpu.

Coolermasters AiO is straight out weak, 100C on mosfet sounds like either garbage tier VRM or air trapped in the case. Or both.
