New(?) "Quiet" PSU-My fan is bigger than your fan!

Fat Bunny · Post by **Fat Bunny** » Thu Feb 19, 2004 3:57 pm

There is a new review at Overclockers of a Super Flower/TTGI PSU with a 14cm

fan. Maybe a good candidate for a quiet PC or review? Does anyone have any experience with these?

IMHO....If you got one, but found the fan unacceptable, you'd be stuck. That being said, the inside of an ATX PSU with a 120mm fan, is plenty cramped. With a 140mm fan where would everything go?

Who knows, maybe this is the future of PSUs.

Looks potentialistic.

Bluefront, what if the 140mm fan is no thicker than say the 120mm inside a Fortron?

Well I suppose the height of the fan is probably the same....but the width is almost that of the PSU itself, adding further restriction to an already cramped airflow. In order to get a 120mm fan in most PSUs, the size of the internal heatsinks is cut back.....for sufficient airflow I guess. Having a 140mm fan in there, just makes it worse.

id buy it cuz its green!

But really, anybody see pix of that guys case! He has a watercooled rig and he STILL has more fans in his computer than me, I mean, these people are crazy! The funny thing is that he has a UT2003 decal on it, while my computer with only 2 fans in the WHOLE thing runs that game at 1240x1024 perfectly... overkill, maybe just a little...

ps: please note the fan on the northbridge!

So are we, just heading in a different direction. But, yeah, most people on the OCForums think 30dBA is inaudible.

You know... for 22" monitors... sometimes 1280x1024 doesn't feel as nice as 1600x1200

... (at least on games I play)

After seeing this guys rig, I also would be wary of his claim of "inaudible at the lowest setting" He mentioned 2000rpm for a 14cm fan, that is easily far from inaudible. IIRC, the panaflo 80mm at 12v is 1900rpm, and fan noise vs rpm only increase with size, larger fans need even lower rpm to match the noise level of smaller fans at the same rpm. This unit is probably FAR from quiet.

I think thats a fan for his MOSFETS on the left side of his mobo, his NB is watercooled from what I can see.

A very good point, 14cm fans are very non standard, it would be extremely difficult to find a more quiet 14cm fan to replace it with if you found the stock fan too loud.

Bleh...even if you assume it is silent, who wants a power supply with led lights?

Light pollution is as bad as noise pollution....I don't want to see my power supply when the lights are off and I'm watching a movie.

All PSUs are inaudible when you have half a dozen of high-powered case fans.
And 2k rpm on a 14cm fan? I find the Papst 4412FGL (12cm) clearly audible at anything over 1k rpm.
Me thinks it will sound like a hurricane.
Really the last site you should look for silencing advice is OC.com.
Unless you think a fan at 4k rpm is barely audible

There is a guy called Chris McQuistion who contributes to OverClockers and he has written some pretty good silencing tutorials for them;

Step-by-Step: How to Build a Cheap and Quiet AMD Dually

Step-by-Step: Building a Quiet PC From The Ground Up

Step-by-Step: How to Quiet those Hard Drives

Personally as a noobie I found all of the above articles helpful.

Regarding the 140mm Supr Flower PSU, for one I would like to know for sure what the relationship between fan rpm and the 3 positions of the controls switch are. If the lowest is 2000 rpm then sure, it will sound like a banshee, but if 2000 rpm is the highest and the lowest is 600 rpm we can maybe it has some potential.

BTW my Antec expensive POS PSU runs the fans at around 1900 rpm and I find it too noisy but my wife dosen't, there is just no accounting for taste!

I'm an overclocker and I visit OC.com and OCforums and I just can't see any similarities between their notion of silence and the SPRC one.

I am not an expert on silencing , but I know my Antec PSU is considered silent by 99.9% of all overclockers , I HATE its noise @ 1700 rpm , it creates 95% of my PC's noise (currently looking for replacement).
Same goes for the Papst 4412FGL , they all find it inaudible @12V , I find it just tolerable @7V.

I used to have 14

fans in my PC , including a cpu fan @5000 rpm... Even an F-16 was silent compared to that

.

Any silencing advice on OC.com should be taken with a grain (or bucket) of salt.
