RMA ON SAPPHIRE RX 6900 XT

I have filed an RMA with NewEgg to return the Sapphire Toxic Radeon RX 6900 XT after it failed. I am not sure but it appears that too much heat caused the card to fry perhaps with the card on the performance setting. I tested it on two other machines, card is DOA.

I recall that the machine was very warm on top of the CPU water cooler suggesting there was a lot of heat in the machine. The Corsair Obsidian 750D Airflow Edition has dual front fans, one rear fan and the H115i water cooler adds two exhaust fans. All of the fans are 140mm which is typical with full tower machines. The amount of heat suggests the video card even with a custom fan profile could not handle the thermal load. Sensors showed the card was 85°C which is typical for modern cards and the custom fan profile had fans at 100%.

The Sapphire Toxic Radeon RX 6900 XT is available with a large 3 fan water cooler. While the 750D can handle this, it would require the removal of all of the hard disk cages. The X690 with 4 M.2 slots would top out with expensive 8TB SSD products. Pricing for Sabrent SSD products has been brutally expensive. So this option would cost in excess of $5000. Hard disks are a lot less costly.

I have returned to using the EVGA RTX 2080 while I consider what to do looking forward. It does suggest I need to fix my hard disks to make sure they are all working properly. I found a new BIOS for the MSI X570-A PRO yesterday so it’s now out of beta and ready for Windows 11. Once I recover my $2500 invested I intend to simply bank it pending a reconsideration about giant video cards.

NewEgg provides a PDF copy of the RMA label making it very convenient. With a glue stick it easy to repurpose the shipping box to send the unit back. The packing tape makes it fast to seal boxes securely for shipping.

I also bought a new pop rivet tool so I would have a better model than the old one I have now. The new one has 4 sizes while the one I have only fits one. This cost $20 shipped so it is not a brutal cost for new tools. The tool box has lots of equipment for repairs of desktop and laptop machines. Pop rivets are not individually expensive but large sets can be pricey.
