Lucru esential care le-a scapat celor care argumentau comportamentul mai bun al HDT-urilor pe i7.

Poza de mai jos spune totul, cantitatea de caldura iesita din comun (in oc) generata pe o suprafata mica transforma procesorul intr-un mic reactor nuclear, nici un HDT nu i-a facut fata pana acum, doar Thor's Hammer a reusit (la limita) evitarea atingerii throttle-ului.

Oh yeah baby...check this out....265mm patrati suprafata pastila Nehalem, 781 milioane tranzistori. Suna periculos, nu-i asa? Nici un HDT nu-i face fata, nu? Dumnezeul temperaturii procesoarelor, nu??? E stai sa-l vezi pe frac'su cu 240mm patrati suprafata pastilei si 1170 milioane de tranzistori. Nu degeaba Intel au facut cooler stock cu heatpipe-uri si prindere cu suruburi special pentru Gulftown

Dar in situatii stock, faptul ca acei tranzistori sunt mai mici si functioneaza la voltaj mai redus nu compenseaza intr-o oarecare masura densitatea dubla? Alaturi de suprafata de disipare mai mare, nu contribuie la rezultate mai bune pe i7 fata de 775 a unui HDT?

(it's an honest question)

In situatii stock nu prea ai de ce sa schimbi cooler-ul box, poate doar pentru silentiozitate

Discutia e complexa dar ca si observatie practica un hdt care a mers prost pe 775 a mers prost si pe 1366, de exemplu Boss 2.

La fel, Thor's Hammer a mers bine pe 775 si a dovedit un comportament bun si pe i7.

Chiar daca acest comportament mai bun (in caz de tdp mic) exista, sporul de performanta obtinut nu va transforma un HDT prost pe 775 intr-unul bun pe i7.

Pentru a intelege mai bine cum stau lucrurile trebuie precizat ca cel mai mult conteaza in obtinerea unui transfer termic maxim (ihs/baza) contactul pe suprafata die-ului.

Testele mele au demonstrat in toate cazurile acest lucru. Daca pe suprafata die-ului contactul nu este bun (stratul de pasta este gros) restul este apa de ploaie, veti vedea un experiment practic (in urmatorul articol), cu Venomous X, care va demonstra acest lucru inca o data.

Daca pun un fenrir pe un sk775 si ii dau oc la proc va fi totul ok, nu?
Daca pun racire pe un i7 si dau oc la proc iarasi va fi totul ok, nu? (cu un WB mai de calitate, gen Acetal extreme)

De ce tot insişti cu Fenrir ăsta nu înţeleg? Ai variante mai bune... atâtea...

Cu un overclocking moderat (fara a creste prea mult voltajul) ar trebui sa fie ok Fenrirul si pe 1366. Oricum depinde foarte mult de urma de pasta (cum calca baza pe ihs), de turatia ventilatorului...

Am mai spus ca Titan Fenrir merge ok pe 1366 la tdp mic dar problema este ca nu are in pachet sistem de retentie pentru sk 1366.

Hai sa mai repetam o data:

-varianta de Fenrir disponibila la noi nu are prindere pentru 1366.
-sunt sanse mari ca performanta pe 775 sa fie mai proasta decit cea pe 1366.
-exista coolere mai bune si mai versatile, Baram sau Flex, la un pret foarte ok.

Daca imi voi lua sk i7 voi investii in Water Cooling. Baram iarasi pare interesant. Ii interesanta constructia sa. In teste iarasi are scoruri ok.
M-ai dat peste cap acum. Am gasit teste cu Baram, este cu 2 grade mai rece decat Titan, pe acelas proc.
Ambele imi plac, iar acum nu stiu ce sa aleg. voi face o lista cu pro si contra. (

DIn faptul ca pe Baram merg 2 ventilatoare il (si acele 2 grade mai putin) voi cumpara.
Multumesc ca mi-ai spus de el.
Intr-un fel sa meritat sa bazai atat cu Fenrir-ul acela, multumita lui am gasit acum unul mai bun.

Foarte "performantul" 212+ are fail in 27 de secunde, nu la extreme TDP.

E Slipstreamul de 1600. Ca si comparatie coolerele decente mentin temperaturi sub 90 de grade la 1.47v. 212+ fiind testat la 1.41v.

Da, 22c si 1600rpm erau acolo, insa voltajul masurat cu MM digital e mai mare (1.47v)

Aici sunt 22c/1200rpm (aceleasi setari, ambient etc..ca si in testul cu twin towere)

Cel mai bun "scor" de pana acum: fail in one second, cam doua secunde dureaza pana dau drumul la prime.

17c ambient, PK-1/2x6000rpm
