PSU under 80$ for fan swap

ZMAJ · Post by **ZMAJ** » Fri Aug 10, 2007 3:31 am

Are there any PSUs known for easy and good fan swapping and taht doesn't cost more then 80$?

My system is x2 3600+, 1 HDD, 7600GT...

fan which I would use is:

Xilence 120mm red wing
voltage: 12V
start voltage: 6V
fan speed 1400rpm
airflow: 68CFM
noise: 21.2 db (this must be lie coz 120mm 1400rpm fan cant do so quite...)

is Seasonic/BeQuiet! StraightPower{DarkPower/FSP GreenPower available in your country?

ZMAJ · Post by **ZMAJ** » Sat Aug 11, 2007 5:17 am

seasonic/be quite/Fortron green power are available.

I wont buy seasonic becouse I've had it, and it was producin buzz.
Be quite is too expensive.

Fortron greenpower is model FSP400-60HLN and it is pretty cheap.
I've read review on SPCR with FSP400-60HLN and on pictures I've seen pretty small heatsinks so I thought this PSU is not good for modding... or am I wrong?

jaganath · Post by **jaganath** » Sat Aug 11, 2007 6:35 am

your system consumes 100W max.FSP400-60HLN is ~80% efficient at that draw. power dissipated in PSU will be ~20W. your fan will easily dissipate 20W of heat.(use this equation to work out exact CFM required)

I was wrong. PSU on SPCR review was GLN, not HLN which is avaliable here.

I think I need to use this 2 formulas but Im confused with DT:

CFM2 = CFM1 (RPM2 / RPM1)

CFM = 3.16 x Watts / DT (Â°F)

DT is ambient temperature of my room?
if my room is 20C is that 53F?

and what if my system is OCed (3600+ @ 2800mhz) is power consumation getting much bigger?

PSU on SPCR review was GLN, not HLN which is avaliable here.

only difference between GLN and HLN is AC voltage input; GLN=100-240VAC, HLN=220-240 VAC.

DT is temperature rise across the power supply (normally between 5-10C).

how much did you have to increase Vcore to get 2.8GHz?

ZMAJ · Post by **ZMAJ** » Sat Aug 11, 2007 8:22 am

none (1.312V is def.)

voltage increse is needed above 2830mhz, and maximum stable is 3050mhz with any voltage... won't go higher.

its brisbane btw.

ZMAJ · Post by **ZMAJ** » Sat Aug 11, 2007 3:50 pm

hmm

I've tryed to use this formula but Im getting crazy small numbers.

CFM=3.16xwatts/DT(FÂ°)

-- 3.16x100/63 and then I get number 5...

Any chance they carry the fanless fortans there?

We got fortron Zen 400W here but its too expensive for me (165$).

I've decided to buy FSP400-60HLN and make a fan swap.
I've read already in old posts that 1 guy here has made a fan swap with FSP400-60GLN (he used Yate Loon D12SL-12)

Fan I will use will be:

-Xilence Red wing
-or I will maybe buyChieftec AF-1225S (which is actually rebranded Yate Loon D12SL-12)

I think maybe its better chiftec fan becouse it starts around 4.5V (im not sure of this becouse its not on offical site, but I've read that on some forum) while xilence starts at 6V.

Only thing which concerns me is that this PSU has really small heatsinks.

amjedm · Post by **amjedm** » Sun Aug 12, 2007 9:50 am

I would try the Yate Loon/Chieftec fan rather than the Xilence fan. IMO the Xilence won't be quiet whereas the YL is a tried and tested fan.

Fans I've used in Seasonic 400W Tornado and Forton 350W psus

Sharkoon Silent Eagle 1000rpm
Aerocool Turbine 1000rpm
Coolermaster (can't remember the rpm exactly - around 1000-1200)

The psus I've modded had bigger heatsinks than the one you want to mod.

ZMAJ · Post by **ZMAJ** » Sun Aug 12, 2007 11:44 am

Xilence is tested fan in croatia and its known for good ratio cfm/silence, but I will use Yate loon coz it has smaller start voltage.

Here in croatia we have fortrons:

- PNF (I had 1 and it had bigger heatsinks then HLN/GLN but its not 80+)
- HLN
- THN

but well jaganath said HLN/GLN so it will be (+ I've read that 1 guy from this forum (nick is mattthemuppet) has already modded it with yate loon)

I have bought the PSU (FSP400-60HLN).

Fan is loud... like I've expected, but PSU+exhaust air is cold in idle (didn't try load yet)

Only problem is that cables are really short (specialy ATX cable) so Im not sure if they will fit in new antec P182 which I will buy in some days...

A Blue Storm 350W I bought for a build had very short cables. The motherboard only reached when I plugged in the ATX converter

unfortenetly I couldn't do a fan swap on FSP400-60HLN becouse there is no 2pin connector but red/black cables from fan goes right in the "board" where all PSU's components are...

it would be too complicated fan swap and I don't want to risk.

I think I will buy Seasonic S12 430W (old S12 not SII) or Corsair VX450 so I may do a fan swap on some of those PSUs

Is old S12 430W good for doing a fan swap? (I will use Yate Loon D12SL-12 fan)

Putting a sleeve bearing fan in any 120mm fan PSU is not good for longevity and not so good for noise either. Why? Sleeve bearing fans are not good when positioned blowing up or down, because the oil tends to pool, and the end of the shaft is essentially unsupported. Rubbing noise and high friction wear are common. Sleeve bearing fans are recommended only for vertical position. See Anatomy of the Silent Fan.

Note that there are no PSUs that use sleeve bearing 120mm fans. I'have not encountered even one in nearly 6 years of testing PSUs. Does that not tell us something?

The S in the model name -- Yate Loon D12SL-12 -- tells you it's a Sleeve bearing model. The L tells you it's low speed.

Besides, with the S12-430, there's no need for a fan swap. It's already very quiet. You could only do very slightly better by going with a slower fan... and risking shorter life.

Didn't early Seasonic S12's had YL's sleeve bearing fans? Before changing into dual ball bearing fans in revised version?

jaganath · Post by **jaganath** » Fri Aug 17, 2007 8:17 am

yes; also in some old Nexus PSUs (NX-3500, 4090, and 9003).

I'm not saying sleeve fans are optimal for PSU use, but if the user is not going to stress the PSU and it's a brand new fan it should last at least a couple of years, and stay quiet right up until the very end.

Yes, for a very short time... No prizes for guessing why.

You're right, I stand corrected. My memory is obviously faulty.

I still would be VERY cautious about sleeve bearing fans in the down/up position. I've heard what they can sound like.

ZMAJ · Post by **ZMAJ** » Fri Aug 17, 2007 2:13 pm

@ MikeC:

well I didn't know that issue about sleeve bearing fans becouse I've seen alot people have used right this YL D12SL-12 for moding their PSUs, and alot PSUs had YL but medium speed model D12SM-12 in (seasonic S12 430w, fortron FSP400-60HLN etc.).

I've had seasonic SII-12 and I wasn't pleased with it's quitness...
My computer is viruatly silent except HDD and PSU.

btw. I can't get old seasonic so I guess I'll have to go with corsair VX unless som1 has better solution for me.

Post by **MikeC** » Fri Aug 17, 2007 2:39 pm

The Corsair VX450 is just about identical to the S12II-430. Only the label and maybe one capacitor differs.

I've just found that my favourite store in croatia is selling USED Enermax Liberty 500W and Tagan super silent 480w TG480-U01 which they've fixed or something, + they give 3 year warranty on it.

Price is very good (90$ for each while usually its 160$ for enermax and 135$ for tagan)

shell I buy some of those PSUs?

ZMAJ · Post by **ZMAJ** » Mon Aug 20, 2007 6:20 am

I bought that liberty coz I read that many of users has done sucsesful fan swap on it.

I must say that this PSU in idle is quiet like seasonis SII-12 in idle.

Seems like a bargain
