[SOLVED] Dissemble Old palit geforce gtx 470

[Poorsigmaguy]

I just got palit geforce gtx 470 for 35$ but temp is getting at 91c in cold weather so i just wanna change the thermal on it as this card is 10+ years old n still in sealed condition but i can't get the heatsink off i removed all the screws but heatsink is still rock solid

Sorry i just opened it using force heatsink was stuck because no one opened it since past 10 years
