The card comes with dual BIOSes, which you may toggle via a switch on the Nitro+’s edge. You can use Sapphire’s Trixx software to check on the status of your fans. Those fans remain idle when the Nitro+ is under light loads-even in the menu of games-and use Sapphire’s Quick Connect technology for easy replacement if needed. The fins are aligned with the length of the card to help dump hot air out of the back of your system.Ī pair of large, dual ball-bearing fans infused with blue LEDs are centered in the card’s attractive blue shroud. The 54-fin heatsink is augmented by a pair of 6mm and a pair of 8mm heatpipes. Starting at the core, Sapphire switched to a new thermal paste that it claims improves thermal conductivity between the GPU and heatstink by 30 percent. Sapphire relies on its flagship Nitro+ custom cooler to tame the RX 590.

But as you’ll see in our benchmarks later, Sapphire’s card manages to meet or even slightly exceed the Fatboy’s performance in games, thanks to its memory overclock and potent custom cooling system. That’s also slightly slower than the 1,580MHz XFX Fatboy on paper. It ships with a 400Mbps effective memory overclock, and the GPU clock speeds hit 1,560MHz, a slight boost over the 1,545MHz reference spec. The Sapphire Radeon RX 590 Nitro+ pushes performance even further. If the card is at fault though, definitely do exchange it, perhaps you're unlucky to get a faulty card (quite unusual for a Nitro+ model to be faulty though).ĭepending on where you purchased your card, if at a retailer, you could easily get it exchanged, if online, you're probably going to have to go the RMA route - which country are you from? If in the UK (and other European countries), you can just get an exchange or refund where you bought it from without needing to go through manufacturer RMA procedure.Here’s how all three of AMD’s mainstream graphics options compare spec-wise: AMD

If you're still having problems it could also be another issue, perhaps PSU related? Checking your profile, you have a 520W Antec PSU? Would be ideal for you to give out complete specs of your pc. It might also seem odd but sometimes monitoring software can cause problems too, especially with new devices so try without using trixx or afterburner for the purposes of stability.

The best thing to do is just test everything under defaults, remove any overclocks on your system. they turn the fans off until the card reaches a certain temperature which can be as high as 60°c). Temps are fine if they're at 70°c under load is a normal temperature really, especially if a pc has poor airflow (they are slightly higher than you would expect but not that bad, I'd be more worried if they were 80°c and above) as for idle temps, 50°c isn't really a problem, modern cards tend to idle at higher temperatures these days because of things like zero fan technology (i.e.
