Èske PC yo fanlès kounye a yon achte sansib? Mwen fè yon anpil nan anrejistreman son ak lide a nan yon PC vrèman silans se bèl anpil. Pyè

innovations resan yo nan mache a PC yo te konsakre nan pwodwi pi bon mache PC yo fanlès, menm si ki pa te aktyèlman objektif la. Konsantre a te sou pwodwi mens laptops ak tablèt, men sa yo gen pwoblèm gwo disip chalè. Intel aborder pwoblèm sa a pa piti piti diminye kantite lajan an ki gen pouvwa bato li yo konsome. Koulye a, yo pa jwenn kòm cho, yo gen mwens bezwen pou fanatik.

Pou egzanp, yon processeur Desktop trè vit tankou Intel Nwayo i7-4960X la gen yon TDP (tèmik pouvwa konsepsyon) nan 130W, ki se cho. Laptops itilize yo gen 45W oswa 35W processeurs, ki te tonbe nan 15W 17w pou machin mens. Nwayo M seri Intel an pote ki desann nan 4.5W. jodi a, menm bon mache bato Intel Atom ki baze sou (souvan Pentium oswa Pentium marque) kouri nan 6-10W.

Gen dezavantaj. Lè bato sa yo jwenn cho, pèfòmans yo gen yo dwe etrangle, oswa yo fèmen tout ansanm. Sa a se amann pou itilizasyon tanzantan tankou pwosesis mo ak Navigasyon entènèt. Sepandan, bato sa yo, se pa apwopriye pou travay pwosesis soutni tankou koreksyon videyo ak bank, epi yo te kapab ki ap lite ak melanje odyo ak koreksyon.

Konbyen fanatik?

Yon PC Desktop pwisan ka gen twa oswa plis fanatik. CPU ak pouvwa ekipman pou la ap gen fanatik pwòp yo, ki fè yo pral jèn grafik kat ak GPUs (grafik inite pwosesis). Youn lè kon sa, fanatik ka separe pral sikile lè kenbe kondui ki gen kapasite ak lòt pati rezonab fre.

Natirèlman, laptops mens ak tablèt kouri soti nan pil, Se konsa, yo pa bezwen pouvwa ekipman entèn. Ni yo gen grafik separe kat: yo yo souvan genyen GPUs entegre ak processeur a, tankou nan "Intel entegre Integrated Graphics".

Si ou pa bezwen yon anpil nan pouvwa, Lè sa a, gen anpil nan ti, PC yo bon mache ki itilize teknoloji yo menm jan ak laptops mens. Yo yo se swa fanlès, oswa fanatik yo se prèske mue, eksepte lè se processeur a mache twòp.

Sepandan, si ou bezwen pèfòmans segondè pou travay tankou koreksyon videyo oswa Gaming grav, Lè sa a, li la toujou yon defi. Ou ka bezwen yon rezèv pou fanlès pouvwa ak apwòch plis inovatè nan refwadisman. Men sa yo enkli tiyo chalè - Ki se de pli zan pli komen nan laptops mens - epi pafwa likid refwadisman.

Mini PC yo ak nettops

Si ou vle yon bagay ti ak bon mache, gen nan multitude la abityèl nan chwa: pou chèche "mini PC"Sou Amazon.co.uk vin pi plis pase yon mil rezilta. Pou chèche "nettop PC"Jwenn yon pi fasil pou metrize 34 rezilta, paske tèm sa a te sitou tonbe soti nan nou. Se pa tout machin sa yo, se fanlès, men pifò ta dwe kouri tou dousman si se pa twò chaje.

Moun tipikman tache sistèm sa yo plat-ekran televizyon yo kouche: yo ap amann pou difizyon videyo, trape-up sèvis TV, ak senp informatique. Yo kapab tou kouri Spectrum, MAME ak lòt Emulation jwèt.

Nan fen a ki ba, gen sistèm bon mache tankou fanlès la Voyo Dous Mini PC. Sa a gen yon 1.33GHz Intel Atom Z3735F, 2GB nan memwa ak 64 GO nan depo chip eMMC ak yon pò 4K dmi pou sèlman £ 89.99. Li nan pi espèk a menm jan ak yon antre nan nivo 10in Windows laptop oswa 2-an-1, men san yo pa klavye a ak ekran. Li kouri yon 32-ti jan Windows 8.1With Bing (prezimableman vèsyon an gratis), men vin yon ajou gratis nan Windows 10.

Cyclone Sumvision a se yon altènatif pi bon-li te ye ak spesifikasyon ki sanble pou £ 98,50. Nan jigabit briks seri se tou vo yon gade.

Si ou vle yon bagay plis pouvwa anpil, gen nan seri a Eggsnow nan fanlès, aliminyòm mini PC yo. Men sa yo enkli Nwayo i3-4010U oswa Nwayo i5-4200U vèsyon ak 4GB nan memwa ak yon SSD 64GB pou £ 212,99 ak £ 248,99 respektivman. Sepandan, yo ka pran jiska 16GB nan memwa, jiska 256GB SSDs, epi jiska 1.5TB kondui difisil. Ou te ka achte yon baz Nwayo sistèm i3 pou £ 156,99 ak anfòm memwa pwòp ou yo epi SSD.

Modèl yo Eggsnow konpetisyon ak Apple la Mac Mini, which starts at £399 for a Core i5 system with 4GB of memory and a 500GB hard drive, and tops out at £799 for one with 8GB and a 1TB drive (or £1,759 with all the upgrades). Sepandan, the latest 2014 Mac Mini has soldered-in memory and is due for an update.

Quiet PCs

Building quiet PCs used to be an art that involved specialised components, such as fanless power supplies and liquid cooling, added damping for rotating drives, and paying attention to the airflow through the case. I assume Chillblast still does some of this. Sepandan, things are easier today, because companies can start with barebones cases like the Shuttle and small ITX motherboards, or just use a tiny Intel NUC (Next Inite nan Computing).

The NUC usually includes a large heatsink and a small fan, so I would not expect an off-the-shelf version to be silent. Sepandan, some companies have designed NUC cases that, in essence, work as large heat sinks. Li evidan, you wouldn’t run one in a confined space, but in normal conditions, they can radiate enough heat to stay within the TDP limits.

Quiet PC’s UltraNUC is an example, with systems being built-to-order in the UK. Nan UltraNUC Atom version starts at £325, while the Abel-cased UltraNUC Pro fanless starts at £595. Quiet PC also offers many other silent or quiet PCs, media centres and entertainment systems, so you might find something that suits you better.

Aleutia’s R50 Fanless – “carved and crafted in the UK” – is a robust but classy-looking NUC variant. Sepandan, it’s really intended for industrial and commercial uses. An R50 standard with a Core i3, 4GB of memory and 60GB SSD costs £599. Aleutia also sells a T1 nettop “Eco PC” with a Celeron J1800 and 2GB of memory for £349, or with 4GB, a 120GB SSD and Microsoft Windows for £499. Tiny Green PC is an alternative supplier.

In all the above cases, double-check to see if the price includes a copy of Windows. Most do, but some mini PCs are sold without an operating system for people who want to run Linux.

Last words

Most modern desktops now run quietly, except when stressed, and the trend towards low-TDP Atom processors and SSDs is making them even quieter. (You can check the TDPs and benchmarks of different chips at Notebookcheck’s Comparison of Mobile Processors.)

The questions you now have to answer are (yon) how much power do you need, ak (b) how much are you prepared to pay for silence?

If you want to make recordings in the same room as your PC, bear in mind that a mouse-wheel may make a clicking noise – yes, I’ve been caught out by that – and keyboard use is probably out of the question. There are times when a touch-screen has the advantage of being quieter.
