Hardware Specification Information

Why is it some information supplied by manufacturers doesn't make any bit of sense whatsoever, and just causes more confusion for the end user?

I'll give you a prime example - a nice PSU from xigmatek linked below

http://www.xigmatek.com/product/power-nrpmc851.php#3

Now, note the following stated on the specifications on that page ;

Cooling System :: 140mm Fan, 2300RPM ± 10%
Noise :: 16 dBA at 1300RPM

Now I know that 2300 rpm - 10% is never ever going to be near 1300 rpm.

So what is the actual noise levels of this product when it is in use with the fan running within the 10% margin of the 2300 rpm speed ?

It's like saying that the PSU operates at 0 db ... when it's switched off that is.

:angst:

Maybe its suggesting that 2300 is the max RPM for the fan, give or take. Where as the 1300 RPM stat is showing what it actually runs like ? 1300 RPM seems a reasonable fan rate for a 140mm fan.

On hardware specification maybe you could pass on the message to include what PCI-E power requirments certain graphics cards have, i.e. 6-pin, 8-pin, 6/8-pin x2.

Either a typo or marketing flim-flam.

Hey you're the shop guys - you can ring them up and get a real answer :p

I would read it as saying that 1,300 and 1,400 rpm are the min and max speeds, and have given the stats best reflecting each value - i.e. airflow at max speed, noise at min speed.

It's equivalent to a car manufacturer telling you the 0-60 time and Extra-Urban mpg figures - both are (in theory) true of the car, just not at the same time.

Judging by the other PSU specs on the site I'd say that that's not a typo. Possibly it's a way of comparing noise across a range with varying speeds, pick a reference speed and measure the noise level at that speed.
