Scan 3XS Vengeance Aura SLI – PC Review

Scan 3XS Vengeance Aura SLI – PC Review

Scan 3XS Vengeance Aura SLIWe’ve already taken a look at the new Intel Coffee Lake processors, and the Scan 3XS Vengeance Aura SLI is the first machine to arrive with one of these new chips inside.

The new rig uses the Core i7-8700K, but that’s not all – it also overclocks the 3.7GHz chip to a whopping 5GHz, and pairs it with two monster Nvidia graphics cards.

Scan 3XS Vengeance Aura SLI PC Review – Components

The Coffee Lake CPU is the star of the show inside this machine, and there’s a lot to like. The 3.7GHz core can usually hit a Turbo speed of 4.3GHz across its cores, but Scan has tweaked it to run at a monster 5GHz – a huge boost.

That overclock is a bigger leap than manufacturers managed on last year’s Core i7 chips, which tended to top out at 4.8GHz or below. The new chip doesn’t just offer more speed: it’s got six cores that support twelve threads, which is a significant leap from quad-core Kaby Lake chips.

The new chip brings more cores and more speed to the table, and its six-core design means that it’s designed for work rather than play. There are plenty of high-end productivity tools that will benefit from six cores, but very few games need more than four.

The i7-8700K doesn’t just make an impact with six cores – it’s made waves by introducing that level of technology for less than £400. That’s a big drop down from the ten-core i9-7900X and the sixteen-core AMD Ryzen Threadripper 1950X, which both cost nearly £900.

Scan 3XS Vengeance Aura SLIScan has slapped the i7-8700K inside an Asus ROG Strix Z370-F Gaming motherboard. It’s got the new Z370 chipset and the revised LGA 1151 socket, but both parts are almost identical to last year’s Z270 hardware – they’re just required because the core-packed Coffee Lake parts require more power management.

The board is familiar elsewhere, but that’s no bad thing. It’s got the usual mix of metallic heatsinks and programmable RGB LEDs, and it’s got beefed-up SupremeFX audio, a secondary M.2 slot and a pair of empty memory sockets.

There are PCI-Express x1 slots free, a hefty shroud over the rear I/O and USB 3.1 Gen2 Type-C and A connectors at the back of the board.

It doesn’t have on-board buttons or a POST display, but the wealth of hardware inside this machine makes this a moot point – they’d hardly be accessible anyway.

The power supply is suitably beefy, too. The Scan 3XS Vengeance Aura SLI is powered by a Corsair RM850x unit that offers a fully-modular design and 80Plus Gold certification.

Scan 3XS Vengeance Aura SLIThe six-core processor is designed for productivity, and so is the rest of the hardware inside the Scan 3XS Vengeance Aura SLI. Only the toughest tools will make use of 32GB of memory, and there’s a 500GB Samsung 960 EVO SSD and 2TB hard disk.

There are two GTX 1080 Ti GPUs in this machine, which means 22GB of GDDR5X memory and a mighty 7,168 Nvidia Pascal cores. They’ve got a significant overclock: their factory-boosted speed of 1,569MHz has been further improved by 50MHz by Scan’s engineers.

The Scan 3XS Vengeance Aura SLI costs £3,799. That’s a lot of money, but it still looks like good value when placed alongside some rivals.

The CyberPower Ultra Threadripper Xtreme had a sixteen-core processor and a slightly lower cost of £3,469, but it only had one graphics card. The home-grown Scan 3XS Carbon Fluid Extreme SLI had two GTX 1080 Ti cards, but it had an overclocked Core i9-7900X, and had a price of £4,950.

Scan 3XS Vengeance Aura SLI PC Review – Design

The Corsair Crystal 570X is being used all over the place these days. Its tempered glass side panels, honeycomb plastic and extensive dust filters are familiar, but they don’t suffer for that familiarity – instead, the Corsair just continues to look like one of the best ATX cases around.

Scan 3XS Vengeance Aura SLIThe Scan 3XS Vengeance Aura SLI uses the red variant of the Crystal 570X. The thumbscrews, plastic accents, PSU shroud and honeycombed plastic behind the glass panels are all red. Scan has also programmed the three intake fans, Corsair Hydro H100i V2 cooler, high-bandwidth SLI bridge, graphics cards and motherboard to all glow with shades of crimson.

Even the PSU’s major power cables are individually threaded with red and black coverings, and the memory is red too.

The case looks fantastic, and the Scan 3XS Vengeance Aura SLI is impressively tidy, with neat cables routed in straight lines. It offers exceptional build quality, although it’s certainly on the large and heavy side – this isn’t a system that will be easy to take to LAN events.

Our only concern is that there’s not much expansion room. The handful of free PCI slots and SATA ports on the motherboard are hidden behind the beefy graphics cards, and there isn’t much room to add storage. It’s a familiar issue with the Crystal 570X, but it’s not much of a concern – anyone buying a machine like this won’t need to upgrade it soon, if at all.

Scan 3XS Vengeance Aura SLI PC Review – Performance

The overclocked six-core processor is a beast. Its score of 26,509 in the Geekbench multi-threaded test is one of the best we’ve ever seen. It’s enough to scythe through demanding work applications and multi-tasking scenarios, and only the beefiest processors are quicker.

Scan 3XS Vengeance Aura SLIThe sixteen-core AMD Threadripper 1950X inside the CyberPower Ultra Threadripper Xtreme was about 1,000 points faster, for instance, and the ten-core i9-7900X inside the Scan 3XS Carbon Fluid Extreme SLI scored more than 30,000 points.

That Core i9-based Scan was more than £1,000 more than the Scan 3XS Vengeance Aura SLI, though, and the new Coffee Lake-based Core i7 isn’t just attractive because of its lower price. It’s better in single-threaded applications, too.

The revised architecture and significant overclock helped the i7-8700K motor to 6,262 in Geekbench’s single-threaded test. That’s the best result we’ve ever recorded – more than 1,000 points ahead of Core i9 and Threadripper chips and their lesser single-core speeds.

The well-balanced, overclocked chip score 5,017 points in PC Mark 8, which is one of the best results we’ve ever seen.

The processor’s six-core design proves potent in multi-threaded applications, and its overclock means it’s better than most in single-threaded tools – which makes the Scan 3XS Vengeance Aura SLI a well-balanced machine for almost all intensive tasks.

Only those who run the toughest software will need anything with more cores. We’re pleased to see that the CPU is bolstered by good storage, too – the Samsung SSD delivered reliably rapid read and write results of 3,068MB/s and 1,730MB/s.

Scan 3XS Vengeance Aura SLIThe graphics cards are no less impressive. Unsurprisingly, the Scan 3XS Vengeance Aura SLI had no issues with 1080p or 1440p benchmarks, and it was hardly a shock that it cut through the 4K tests. It hit a minimum of 71fps or better in every game, and its best average was 158fps in Shadow of Mordor.

Those scores are sometimes a little better than the Scan 3XS Carbon Fluid Extreme SLI which also had two GTX 1080 Ti cards, no doubt thanks to the better processor and hefty GPU overclocks.

This machine will not struggle with any gaming task, whether it’s 4K, multi-monitor, VR or widescreen. Importantly, it will also handle any graphically intensive productivity tool.

Scan’s overclocked components push the machine’s thermal design, though. The processor’s peak temperature of 94°C is about as high as we’d like, and the Scan 3XS Vengeance Aura SLI produced a low, evident rumble when running tougher applications.

It’s not a disaster at all, but we wouldn’t want that processor any higher – and you’ll certainly know that you’ve got a powerful PC in the office.

Scan 3XS Vengeance Aura SLI PC Review – Conclusion

Scan 3XS Vengeance Aura SLIThe Scan 3XS Vengeance Aura SLI is a superb system. The six-core processor provides ample multi-threaded pace, and the huge overclock delivers more single-threaded speed and better balance than other machines with multi-core CPUs.

There’s loads of memory, two monster graphics cards, great storage and a fully-featured motherboard. The case looks the part, and the Scan is relatively quiet considering the power inside.

That’s all great, but the £3,799 price pushes this machine out of reach for many people – and that’s fine, because this isn’t a machine for the average gamer or home user.

If you do frequently use high-end productivity software for design, streaming, video production or anything else, though, the Scan offers stunning pace. Only a few people can use this much power – but if you’re one of those folks, then few machines are as good as the Scan 3XS Vengeance Aura SLI.
