Zgomotul curentului de aer din sursa?

[odin]

Salutare!Sunt nou p'aci dar ma chinuie si pe mine zgomotul produs de PC.
Am reusit un compromis cu ventilatoarele de pe proc(Gigabyte de aprox 90mm,blue) si placa video(stoc,de pe 9550aka9600 de la GeCube),hddul e silentios(seagate barracuda 7200.7 de 80GB).Am schimbat fanul de la sursa cu unul mai silentios(nidec sau delta-12v,0,14A-traiasca PCurile second de firma!), am decupat grila de protectie de la acest ventilator.
Ce ma termina este zgomotul produs de curentul de aer ce se formeaza in zona sursei de alimentare.Ce ati reusit la acest capitol?Am avut niste probleme si ma gandesc sa schimb sursa de alimentare cu una de firma si cu fan de 120mm;partial si in speranta ca o sa fie mai liniste.Ce ziceti?se merita?Pt ca in principiu un ventilator mai mare functioneaza la o turatie mai mica,dar baga acelasi debit de aer.Si tocmai aerul e problema.Ajuta cu ceva faptul ca sursa are peretele extern in fagure?
Poate stiti undeva si niste reviewuri pt silentiozitate.
Merci anticipat!

Incearca sa faci un muffler pt sursa. :D

sau daca tot o desfaci poti sa pui un Spire clearblue sau un arctic cooling de 80mm silent si ai rezolvat o mare parte din probleme, asta presupunand ca ai deja grila de sarma pe sursa.
oricum eu pt asa ceva voi merge cat de curand si imi voi lua un seasonic.

...oricum eu pt asa ceva voi merge cat de curand si imi voi lua un seasonic.
gargamel uită-te cu atenţie la un Silverstone Element sau Akasa 80+ în aceeaşi bani de S-12 430. ;)

[gargamel]

din ce am vazut akasa-ul e ceva mai zgomotos ca Seasonic-ul... dar nucleul Enhanced e ok.. tinand cont ca e acelasi cu Zeus parca nu?

[burebista]

... dar nucleul Enhanced e ok.. tinand cont ca e acelasi cu Zeus parca nu?
Nope. Zeus sunt Etasis, Strider şi Element sunt Enhance, cu menţiunea că Element e bazat pe noul Enhance 80+ (ca şi noile Akasa 80+). Aici (http://www.jonnyguru.com/PSU/Element500/) un review la Element 500 (în caz că mi-ai scăpat postul (http://www.computergames.ro/forum/showpost.php?p=36121862&postcount=14) de pe CG). ;)
Cât despre zgomot, dacă eşti din Bucureşti, cel mai bine e să le asculţi cu urechea ta.

[gargamel]

acum intrebarea vine... un review pt akasa?... ca nu am reusit sa gasesc.. folosesc tot ADDA??...

[burebista]

Habar n-am de Akasa (nu prea se-nghesuie lumea la review-uri :)) dar atâta vreme cât Element-ul e cu 8 RON mai ieftin :P şi ai şi review la el cred că se uşurează alegerea...
Cât despre fan la Akasa cred că o fi tot Akasa... Cel mai bine e să-l întrebi pe QD.

[gargamel]

da.. dar ei nu au element... extreme au element dar nu e plus e ala simplu

[burebista]

gargamel stăi oleacă. Sursa mamă certificată 80Plus Enhance ENP-5150GH (http://www.enhanceusa.com/file/72_specification.pdf) are 2 puişori: Akasa AK-P050FG8 - 500W (http://www.pc-coolers.ro/) (la QD) şi Silverstone Element ST50EF (http://www.extreme-computers.ro/produs.php?cod_produs=1149833928619) (la M.A.D.), aşa că oricare dintre Akasa şi Element este la bază noul Enhance.
Alegerea uneia sau alteia ţine fix de gustul/urechea ta.

[gargamel]

pai de aia ca ma bagasei si pe mine in ceata ca le stiam cam la fel... dar la akasa nu am vazut review-uri.. asta e partea trista

[gargamel]

gata
sunt detinatorul unui Element de 500W care urmeaza sa fie montat :D... bye bye annoyng sounds :D

[Net_Devil]

Impresii impresii

[burebista]

Subscriu la cele spuse mai sus. :D

[gargamel]

impresiile ar fi urmatoarele...
1. e muuult mai silent decat vechea Delta de 350W.(cred ca momentan singurul vent care se distinge este cel de pe placa video <un Leadtek A6600GT TDH>)
2. e la fel de grea ca vechea Delta (2.5kg)
la tensiuni nu ma pot baza pe senzorii de la mobo ca tot timpul au indicat aiurea..... adik variatii chestii trestii...
3. nu e sursa din linkul trimis de tine (acea 80+), dar scrie pe ea ca e tot >80%
4. Cred ca e tot Enhanced tinand cont ca ei le cam fac sursele celoor de la Silverstone.
singurul minus care ar fi pt mine in momentul de fata este acela ca mai pot folosi priza master.. ca nu imi mai scade consumul in momentul in care e in stand by de ce???...... are sistem de protectie si merge ventul pana se raceste sursa?.. ca altfel nu imi explic.
ce nu inteleg este de ce sta procesorul mai sus si cu tot s2kctl-ul meu care facea treaba bine nu mai scade sub 50C.....hmmm iar inainte statea pe la 46-47C

[gargamel]

Hi Bordan,

indeed there are two quite different PSU.

The ST50EF plus is not available in the market now. The will come into stock Hamburg in about two weeks.

The price for both is different too. The recommended end user net is higher by + version for about 8 €.

Please take all specification form our home page.

deci sunt 2 surse diferite.... cea din review-ul tau si cea de la extreme. Nu ma vait.. singura problema pe care o am este cu consumul in soft-off care mi se pare enorm. Sa vad ce raspuns or sa imi dea baietii de la SilverStone. Sa vorbesc cu M.A.D. poate mai dau o diferenta si trec la un S12 500W.. dar mai intai sa vad ce imi spun ei, ca sa nu ma apuc sa arunc cu banii degeaba.

[burebista]

Buey, astia-s bolnavi cu capul. Cind m-am uita io pe site-ul lor (acu fo' 3-4 zile) nu era nici urma de 500 Plus. Era numa 400 si 500. Acuma vad ca au mai intercalat un 500 Plus cu aceeasi cutie ca 400 (simplu fara Plus).
I'm puzzled, o sa-l intreb si pe ala de pe SPCR ce-i cu fantoma asta...
Intre timp pune si tu raspunsul de la Silverstone...

LE: Tot raspunsul oficialului Silverstone de pe SPCR:

Hi Pitt, thank you for the question. The difference between the ST50EF and ST50EF-Plus is in the efficiency at low and full load levels. As you may already know, the ST50EF-Plus is a 80 PLUS officially certified PSU so it is capable of greater than 80% efficiency at 20%, 50%, and 100% loading.

While the ST50EF is 80% efficient under most circumstances, it drops below 80% efficiency around very light and full loading conditions. Although a difference of 3% ~ 4% may not sound like a lot, the effort to get over 80% at all loading condition is quite challenging technically (hence the cost difference).

If your system operates between 150W ~ 400W then the difference between the two Element 500W power supplies is almost nothing. However, if your system operates outside of that range, the ST50EF-Plus will give you a small efficiency adavantage and the oppurtunity to earn rebates from the 80 PLUS organization (for system integrators only).
Cu alte cuvinte mult zgomot pentru (mai) nimic...

[gargamel]

mda.. si daca ma uit la 80plus.org la certified apare ST50EF simplu.... fara nici un plus.. asta e partea tare.
http://www.80plus.org/docs/datasheets/Silverstone_SST-ST50EF_500W_80PLUS_Report(1).pdf
despre faza cu consumul in soft-off nu mi-au raspuns nici pana cum cu toate ca mi-au zis ca in 1-2 zile imi dau raspunsul.

Hy!
Anything new?... i want to know if i will have to go with my PSU back to the retailer who sold it to me... and ask for another one...

Hy!

I have recently bought an 500W Element PSU (ST50EF).
My old PSU was a Delta Electronics Giant Power 350, Passive PFC.
since i have changed my PSU i am dealing with some problems using my master surge protector. The problem looks like: i put de PSU into the Master, I switch on the PSU power button and the peripherals are all off. Good. I put my PC on, and next off (soft off mode). The peripherals are still powered. I am rotating the button on my master for maximum power (84W).. and nothing.. my peripherals are still on. weird. Then I try the same thing with my speakers (Logitech X530 74W) in master mode. I put them on, and i am playing with that master's wheel to set the proper power of switching. Whith these at maximum volume, but whith no audio signal, my master detects the power around 25-30W. If i go up.. the peripherals are OFF. So i don't know what to say.... is this PSU getting more power in soft off than my speakers running??... (my master can be set between 18W and 84W). If this PSU is sucking more than 80W in soft-off... there is a biiig problem. Can you help me to solve my problem?...
Thank you.

raspunsul de la silverstone :rotf:
Dear Sir :

We are very sorry to reply your question so late.

We are not many sure what is “master surge protector”

Can you list your hardware component to us .

And it will be better to send us the product web address of your master surge protector.

Thanks you very much.

Oricum am rezolvat problema. Am vorbit cu M.A.D. si am luat un Seasonic S-12 de 500W ... s-a rezolvat problema.... oricum cred ca era din cauza ca surse precum Silverstone, Tagan si alti producatori de top aleg 3A pe +5 Vsb, iar Seasonic are la fel ca fostul Delta 2A.. cred ca de aici au venit toate aiurerile... oricum consider ca am pus mana pe o super sursa.
