Default Probleme Sapphire 280x

Am un prieten cu placa asta defecta!
Gpu vrm1 ajunge la 90+
Miroase a ars...

Nu stiu daca trebuia sa fie asa distanta intre vrm si radiator, din ce vad pe google pare sa fie ok
Oricum se incalzeste in 25 sec la 90C

Se mai poate face ceva?

Idei?!

VRM-ul la 90 grade nu reprezinta o problema, care este defectul exact? Din ce vad in poza a doua s-a ars un etaj de alimentare.

Pai vrm 2 are 25-30C
Placa se oprește!
În idle!!!
pornesc pc-ul și imediat miroase a ars! Apoi intra in win, pornesc Aida64 și are deja 80+, apoi ajunge la 90 imediat!
De asta m-am sunat colegul! Că mirosea și s-a oprit!

Asculta putin la asta... cica tipul ala de VRAM (mosfet) se incinge foarte, foarte mult.

Probabil ca in timp, din cauza raciri slabe si a faptului ca vram-ul este inghesuit pe PCB, nu a mai rezistat si a pocnit (scurtcircuitat), din cauza asta miroase a ars. Nu sunt electrician, dar e cam clara treaba...

GTX 1070 clar este mai buna daca vrei sa le compari. Insa la 1080p un GTX 1060 6gb se descurca fara probleme si ar fi variant cea mai buna ca pret/performanta.

acel vs era raportat la sistem si TV, NU prea vad cum va putea beneficia maxim de 1070 pe 1080p. Iar 600 ron in plus pot folosi la altceva.
dupa niste calcule, am comandat acel MSI 1060 6 gb

Normal ca la 1080p nu l-ar fi ajutat foarte mult acel GTX 1070, ar fi fost overkill, placa aia este mai potrivita pentru 1440p ca sa stoarca tot ce poate din ea. :P

ia un 1060 6gb , il am si nu a pus placa in cur nici un joc daca nu dai prea tare cu AA-ul, 1070 cred ca e o idee overkill pt 1080P iar diferenta de bani dintre 1060 si ea o poate baga in altceva.

Aia sint mosfetii DirectFet, racirea de face prin contact cu capsula.

https://www.google.ro/search?q=direc...&bih=515&dpr=1

Design flaw, sau chiar (mai degraba) inductor in scurtcircuit sau cu spira in scurtcircuit.

Daca era tot vrm-ul cu probleme nu era doar o faza aiurea.
