TechPowerUp checked out the XFX Radeon RX 7800 XT Merc 319
A quote from the article:
The factory-overclocked XFX Radeon RX 7800 XT Merc 319 comes with a powerful triple-slot, triple-fan cooling solution that uses a metal shroud instead of plastic like on many other cards. The cooler runs much cooler than the AMD reference version, by over 20°C, and noise levels are greatly improved, too.XFX Radeon RX 7800 XT Merc 319 Review
