So , for all of experts on this forum pls help .

So I have Radeon 7770 wich I put in my friend PC , but fans wont spinup and it dosent get that hot and performance is awful . I installed msi afterburner and CPU CLOCK reads 0 and Memory Clock reads 0 also RPM FAN reads 0 PSU in that PC has 6pin plug for GPU also I checked 12v and 5v rail on that psu while pc is runing with 7770 and on 12v it reads 12.25 and on 5v rail it reads 5.5v. I installed Win 10 pro 64 bit fresh install . Same thing but when I put it in my PC it works just fine .

Friends PC
C2Q Q8400
4GB DRR3
HP COMPAQ DC8000

My Pc
Athlon X4 750K
8gb ddr3
msi fm2 a55

once the gpu detects high temps the fan should spin, no matter the afterburner settings

can you make spin the fan? too hard to move? too much dust inside the pc and gpu specifically?

the fan could very well be dead, so a replacement fan could be required, especially possible on a old gpu
