Noctua NF-F12 Noctua NF-F12 The NF-F12 at first looks pretty standard, without anything different but when you take a closer look, this fan has some interesting features. To start is the impeller itself. Noctua call this a Heptaperf Impeller, its custom designed to work in tandem with the frame and has been optimised to achieve a perfect balance between power and quietness. In the fan its frame at the corners you will see a stepped area, this is the Stepped inlet design. It is designed to add turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments. This means compared to a normal design of fan, this should have a quieter intake noise and should do better in a pull configuration on a heatsink. On each corner of the heatsink you will find the extra-soft silicone anti-vibrational pads which are there to minimise the amount of vibrations that leave the fan while still keeping full compatibility. To the rear of the fan we see some pretty large changes when compared to a normal fan. First off are the eleven Stator guide vanes that straighten, channel and focus the airflow. This should allow the NF-F12 to rival the performance of a normal design fan running at much faster speeds. In the center of things is the new SS02 Bearing, Noctua’s second generation of this renowned and tested bearing. The improvement is the placement of the rear magnet; it’s placed closer to the axis to improve stability and durability of the fan. The bearing also features a metal bearing shell which is said to be made with the highest possible degree of manufacturing precision and is made entirely of Brass. The last two of the features are the custom designed PWM circuitry and Ultra-low power consumption. The PWM circuitry uses Noctua’s custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology which by smoother torque impulses reduces the ticking noise you often hear from PWM fans when running slowly. With this fan its Ultra-Low Power Consumption, it only draws 0.6W which is 50% lower than many fans in the same speed range. Compare it to a typical 2W fan and you could save half the price of the cost of the fan after five years of continuous use. The NF-F12 mounted on a Cooler Master Hyper 412S heatsink.

Noctua NF-F12 Noctua NF-F12 An NF-F12 ar dtús tá go leor caighdeánach, gan rud ar bith eile ach nuair a dhéanann tú a chur le breathnú níos dlúithe, tá an lucht leanúna roinnt gnéithe suimiúla. Tá Chun tús a chur leis an impeller féin. Noctua glaoch seo impeller Heptaperf, a saincheaptha a ceapadh a bheith ag obair i gcomhar leis an fráma agus tá optamaithe le cothromaíocht a bhaint amach idir foirfe chumhacht agus quietness. Sa lucht leanúna a chuid fráma ag coirnéil feicfidh tú limistéar céimnithe, is é seo an dearadh inlet neartófaí. Tá sé deartha suaiteacht cur leis an teacht isteach d'fhonn an trasdul a éascú ó sreabhadh laminar chun sreabhadh suaite, a laghdaíonn torann iontógáil toin, a fheabhsaíonn astú sreabhadh agus méadaíonn cumas trí shúchán, go háirithe i dtimpeallachtaí spás teoranta. Ciallaíonn sé seo i gcomparáid le dearadh gnáth de lucht leanúna, ba chóir é seo a bheith torann iontógáil níos ciúine agus ba chóir é a dhéanamh níos fearr i gcumraíocht tarraingt ar heatsink. Ar gach cúinne den heatsink gheobhaidh tú an seach-bog silicone frith-vibrational pads atá ann go n-íoslaghdófar an méid vibrations a fhágann an lucht leanúna agus a choinneáil fós comhoiriúnacht iomlán. Ar chúl an lucht leanúna a fheicimid roinnt athruithe móra go leor nuair a dhéantar comparáid le lucht leanúna gnáth. An Chéad iad amach ó aon cheann déag de eití treoir stator go straighten, threorú agus an sruth aeir ag díriú. Ba chóir go mbeadh ar chumas an NF-F12 a rival le comhlíonadh ag lucht leanúna dearadh gnáth ag rith ag luas i bhfad níos tapúla. I lár na rudaí a bhfuil an nua SS02 Bearing, an dara glúin Noctua de seo ar a bhfuil cáil agus tástála. Is é an feabhas an socrúchán an mhaighnéid chúl; é a chur níos cóngaraí don ais chun feabhas a chur ar cobhsaíocht agus marthanacht an lucht leanúna. An bhfuil le feiceáil chomh maith le shell bhfuil miotail a deirtear a dhéanamh leis an leibhéal is airde is féidir cruinneas déantúsaíochta agus tá sé déanta go hiomlán de Prás. Is iad an dá deireanach de na gnéithe saincheaptha an deartha PWM circuitry agus tomhaltas chumhacht Ultra-íseal. An circuitry PWM Úsáideann saincheaptha a ceapadh Noctua ar NE-FD1 PWM IC a chomhtháthaíonn Smooth Suimeanna caipitiúla Drive (SCD) teicneolaíocht a laghdaíonn ag impulses chasmhóiminte smoother an torann tic leat a chloisteáil go minic ó lucht leanúna PWM nuair ag rith mall. Leis an lucht leanúna a chuid Tomhaltas Cumhacht Ultra-íseal, tarraingíonn sé ach 0.6W atá 50% níos ísle ná mar a lucht leanúna go leor sa réimse luas céanna. I gcomparáid é le lucht leanúna 2W tipiciúil agus a d'fhéadfadh a shábháil leath an praghas ar an costas an lucht leanúna tú tar éis cúig bliana d'úsáid leanúnach.
