Almost 90?! My stock wasn’t reaching that high. It wasn’t going above 83 for stock. Currently clock at 1875 MHz and 825 mV, my temp is stable at 74.So I am in the midst of finishing my 3080 FE build and I can definitely echo what @Maeiourk and @PorKOON did:
I unscrewed the end of the PCIe Riser and I added a mobo standoff to the existing standoffs, which pushes the card out towards the case
This actually helps with aligning the ports in the back and the card is very nice and stable in there
Currently working on undervolting - when pure stock, temps peaked at 89°C with throttling down to 1635 Mhz but so far at 950 mV, I'm getting clocks at 1800 MHz and temps at 81°C - massive improvement!
