Best 140mm fans for radiator.

clone · 11 Jan 2019 at 13:32

When I had the old model evolv I used the stock fans and found them lacking the power to use a lot of air.
I boxed the stock fans in the x as I got a good deal on the 5 red led MLS and they push a fair bit of air on low,and I've now got the option in the summer when it gets hot I can run them faster to cope.

Yeah, the Evolv X comes with 1200rpm variable voltage fans while PH-F140MP we can buy are 1600rpm PWM fans .. that is 25-33% more airflow/static pressure from real PH-F140MP. Considering PH-F140MP have simialr performance and costs less than 1/3rd what MLs' cost at £29.99 each against PH-F140MP 2-pack for £16.26 it's no surprise OcUK has a hard time keeping 2-pack of PH-F140MPs in stock. I'd much rather spend £8.13 than £29.99 for a fan.

Which MLs did you get, the 1200rpm or the 2000rpm models?

2000rpm ones I would have just bought some more phantek fans but as the MLS where on the MM I got them instead.

I have the Silent Wings 3 PWM (BL067) Max 1000rpm and it seems to not be very silent at low rpm, I can hear it starting to make a quiet but low frequency noise at below 500rpm and it gets louder the faster it spins. I always thought that it was near silent until I put it into a silent case and now it's the only thing that bothers me. So I may look atthe ML140's myself.

Arctics are good though and cheap.

I have those SW3 fans like yours and mine are very quiet at 500rpm.

Thanks for the info. Guess you are in the lucky group that MLs work/sound good for. I almost always use fans that have 300-800rpm more speed than I normally run them. Heck, I've used 2500rpm fans that never ran over 1150rpm, even during heatwave summer days at full load. Well, once in a while I would do a shock and awe and turn off all fans at full load for about 5 minutes to get temps up to about 85c, then start case and cooler fans back up and they would spin up to 2500rpm :eek:

for maybe a minute before starting to slow down and be back to normal 1050-1100rpm in a few minutes.

All of my systems go from idle to full load temp almost instantly .. take less than a minute to be within a couple degrees of maximum temp, and in less than 2-3 minutes temp graph line is flat at full load temp until dropping back to within a couple degrees of idle temps in same couple of minutes.

I just bought another SL3, now I have two 140mm SL3's on my GPU lol. They don't go above MSI fan speed of 16-17% at 100% GPU usage for 30 minutes (45% MSI fan speed is 100% fan speed of 1000rpm).

So running the games I play it should never need to go above these speeds and now my computer is inaudable over my speakers.

I will get water cooling in the future so I dont have to mess around with a lot of fans. I've spent £150 on getting it quiet over the last year or so (different fans etc) should have just water cooled it. One day I may live somewhere where I can shut the thing outside the room.

Not sure why I buy exactly the sane fans and some hum and some are silent. Ive returned about 5.

My Evolv X fan config is 3 x NF-F12 iPPC 2000 PWM that came with the Ryujin 360 mounted as a top radiator exhaust and I added a further 3 of the same model as from intake with a NF-A14 iPPC 2000 PWM as rear exhaust.

Very happy with noise and temperatures.

Sorry to bump this old thread, maybe someone is watching, but I have 2 x phanteks ph-f140mp's which I bought in china, as many say they are awesome, and were 5 quid in china, and they only seem to spin to 1350rpm. They do not have any writing on the sticker, just the phanteks shiny silver name sticker. I heard someone say before that the ones WITHOUT the naming on are the cheaper ones they put inside their pc cases, do you think I have those?

Also, IIRC, the packaging had written on them ph-f140mp @ 1600 +/- 350... What does that +/- mean? clearly its not they can spin over or above that 1600rpm number.

I have to say they are pretty silent even at 1350rpm, silent up to about 1200. I can heat the air but my nh-c14s is still cooking @ 85c whilst gaming... only 1 on there atm, in pull.

They were the ones with underscore bk at the end of the product code as well IIRC. They do have the rubber mounts on them and are pin PWM.

Is this the fan?

yep. but without the version number on it

Do you know what the +/- means? I see that on a lot of fans and i swear it was on these as well, but dont have the box now. I was hoping for a 1600pwm fan. dont mind a little noise, as usually blast the volume from a hi-fi when gaming anyway

I guess the fact the spec sheets @ 1600rpm +/- 250 and my max rpm totalling 1350 isnt a coincidence

You said +/- 350 in your first post and now +/-250.

I said IIRC which means if i recall correctly... And then stated the spec sheets so I'm guessing I didn't recall correctly... Looked at several boxes of the fans, see +/- 250. do you know what that means?

maklabouhlel · 12 Sep 2020 at 01:21

1600-250=1350
1600+250= 1850

So the fan can run between 1350-1850rpm.

UUmmmm Ok... My maths isn't that bad, but thanks... I guess? I'm asking what does the 250+/- symbol mean that you seen on fan spec sheets. Have you noticed it before? Theres a number next to the rpm with + symbol above an underscore.

Every other fan I have owned goes up to the stated number.

+/- means allow for deviation from the quoted rpm.

maklabouhlel · 12 Sep 2020 at 01:37

I think I know what you're asking. It means plus or minus.

You're sure? I thought that but every other fan I've ever owned has a deviation of like 1-50rpm, I'd say 100 absolute max... Isn't 250 a little excessive and like said, a coincidence? It's an exact number. Wow thats crappy... So If I want 1600 rpm in future I should buy a 2000?

Yeah it's what i thought too... but in 15 years of building pcs ive never experienced it. I know noctua mention +/- 10 percent

Anyone wanna buy some 1350 rpm phanteks? Theyre quiet as hell
