Zdravím Zakúpil som si tieto ventilátory,sú tiché,otáčky sú približne 1400ot/min. Ale čo sa týka odoberaného prúdu na 1 ventilátor,výrobca udáva 0,16A,čo je 160mA,podľa prilepeného štítku.Meral som elektrický prúd a u mňa bol nameraný prúd 1 ventilátora približne 50mA,čo je rozdiel 110mA. Takže prietok vzduchu nebude udávaných 28CFM,ale podstatne menej. Z toho vyplýva,že výrobca zavádza.Upozornite na to výrobcu,nech si opraví údaje a to odoberaný prúd v mA a taktiež pritok vzduchu v CFM. Ďakujem.
