140mm case fans... - Page 5

post #41 of 50
Thread Starter 
OK these fans are weird.
As with any fan I install I check to see the speeds at every setting so I can pick my fan curve in the BIOS.
I booted it up at the fans were set to the lowest 12.5% which I default to...and they read 0rpm.
I thought that's odd, PWM fans usually just go to their lowest PWM setting when it's too low as long as the header isn't set to off...so I looked...and they were spinning...
O...K...

So yeah the BIOS readings at each setting are...

12.5% - 0rpm (they're actually spinning, I don't understand this!)
25% - 200rpm (that's more like 10%! This is the minimum PWM speed on the spec sheet)
37.5% - 560rpm (still 200rpm off what it should be)
50% - 930rpm (OK! That's close enough!)
62.5% - 1250rpm (spot on perfect)
75% - 1550rpm (a bit high but well within reason)
87.5% - 1780-1800 (same again)
100% - 1960-2000rpm (that'll do! smile.gif)

So yeah...the performace up to and including 37.5% speed is...strange to say the least.
Also causes a bit more of a headache trying to set a custom fan cuve but hmm...

I don't know. Sounds a 'bit' drastic to me. tongue.gif
These the Vardar F-140ER, correct?
Will be interesting to hear your impression and see data. thumb.gif

Your jokes are just like mine, now I know how I make other people feel frown.gif
I'm not gonna stop...but at least i know tongue.gif

Yeah the F3-140ER...my initial impressions are the screw holes are wrong and need fixing and the fan speeds at the low end of the PWM range are just WRONG...

So normally I'd set my fan curve to idle at ~600 and when it's slightly warmer ~800

With these I can get them to idle at 560 which is fine but 930 when it's a bit warmer which may be a bit much...
It remains to be seen though in actual use at night when I want my quiet tongue.gif

So at the moment 37.5% @ 40C (lowest temp the BIOS will let me set to), 50% @ 45C, I might end up making it 50% @ 50C to get them to spin lower when it's warmer...ehh...

If it was accurate it would have been much better as 25% = 500rpm, that would have been perfectly acceptible then 37.5% would be @ 45C and 50% @ 50C...

Every other PWM fan I've used has actually matched what it is supposed to be so at 25% it would be around 25% speed, 37.5%, 50% would be all more or less what they should be but the speed control on this fan is really out of whack...
I might swap the cables around to see if the second fan reads more accurately, that'd make sense!

Not finding fault here so please don't take this wrong. What are you basing your 12.5, 25, 37.5, etc percent on? Is it actually the percent of total non-pulse rate or is it just something showing on a screen from software for mobo? Same can be said for actual RPM reading based on software readout saying it's % of speed. Both the PWM signal source and receiver software and hardware are programmed, and there signal / pulse curves are not necessarily linear.

Best example of this I have is TY-147 vs TY-14A fans. Same fans with different curves giving TY-147A not only a lower idle speed, but at lower RPM all they way up to about 1000rpm @80% where PWM/RPM ratio progressively increase as PWM% increase to full speed.

Getting a decent fan curve with these is hard work smile.gif

I thought I'd managed to get them running at ~1200rpm @ 60c but then they slowly went up to 1300...needs more work...

Definitely gonna set 50% speed @ 50c rather than 55...62.5% @ 65 maybe? then 75% @ 70

Regarding the R5's included fan screws - yeah I ended up getting a $7 box of screws at Home Depot, the Everbilt "Electrician's Machine Screw kit" which includes a TON of #6-32 screws (from 3/4" up to 3" in length, 370 pieces total).
Warning: Spoiler! (Click to show)

I'm including a picture of the 1" #6-32 and the 1-1/4" #6-32 to compare to the default Fractal R5 screws.
The Fractal is 1-1/8" in length, as you might have guessed. The extra length on the 1-1/4" is plenty to screw in your fan of choice haha.

Nice visual and physical explanation. thumb.gif
Could I use it in my Define fan post?

Is that a post about being a fan of the Define or a post about Define fans? wink.gif

Just FYI, the silly mounting system only exists in the Define R5, the Define R4 and Define S use different mounting mechanisms. The R4 because they mounted in a fan bracket and the Define S probably because there's no HDD cages so fans can be attached screwing from the inside of the case.

You do know, we all like a little alic but none of us like a smart alic. poke.gifbiggrin.gif
