Fanless Ultra Powerhouse PC by EndPCNoise

Sidney · 24th February 2006, 08:49

EPCN offers a number of systems in several series. The unit submitted for review comes from their Powerhouse series, and it is one of the most elaborate offered: A large, completely fanless, high performance system housed in the Zalman TNN-500AF case, PSU and cooling system. It's not a system of high interest for the average PC buyer, but it is certainly of interest to most readers of SPCR — or anyone needing a truly quiet PC. This is the first system End PC Noise has submitted for us to review.

The measured SPL went up from the room ambient of 19 dBA@1m to 20 dBA@1m when the EPCN PC was turned on. The HDD seek noise rarely deflected the meter's indicator by more than another decibel.

The DVD-RW drive added the usual whooshing noise when it was used. During the initial scan of the disk, the noise was fairly loud, reaching 40 dBA@1m. In a secondary speed level reached about 40 seconds after disc insertion, the noise level dropped to about 30 dBA@1m. In normal play mode of a DVD or CD, typical noise was not audible.

A) Find myself a 19 dBA house.
B) After all the time, money and efford spent; the DVD Drive makes too much noise.
B) 20 dBA from a system has no fan and CD/DVD drive while there are 18 dBA fan advertised.

A=never going to find one
B=give me a break
C=believes no one

The only time the PC is noiseless for sure = turn it off.

just use their dBA values to compare other hardware tested at their site; those values are comparable and ok

if I breath heavily in at 1M from dBA it goes above 30dBA btw

Never said the dBA value was off.

Just people are getting silly; breathing normally to a person sleeping next to you = >30 dBA? ..... and people are still getting marry and continue to sleep together, yet they go spend money on a 20 dBA noiseless PC case

uhm.. you did say their values are off, since he's measuring this <20dBA in his kitchen

Aaah, the noise you're producing, that's breathing or what ?

In his kitchen? 19 dBA? A kitchen!!! with refrigerator and gas oven kind of kitchen??? No way .....

White noise in a regular constructed house, 19 dBA, no way. He needs to go to an audiologist; an approved sound room to test his meter. Or, show me the calibration or certified calibration before I accept it.

I must be plugging my ears with hearing aids and couldn't hear anything during the 10 years I worked as Materials Manager responsible for all purchases and production inventory control.

@Lazyman: it's an ex-kitchen, only used for testing now, no active appliances in there
