Graphics card temperatures general range from 40C to 80C. Most high end graphics card such as R Series and GTX10 Series typically display temperatures 50C-70C and up to 80C-90C during loading. We design heatsink and fan assembly specially to reduce the temperature as much as possible. If you are having a trouble with heat, we recommend turning your fan speed up to 100% loading and adjusting your voltage and clock speeds at the optimal performance of heating ratio.

No, the video cards must be matched to properly implement SLI. The two cards can be from any manufacture, as long as the GPU and memory type are the same. For best results, ARKTEK recommends to use the same brand cards and same model to avoid problem and compatibility issue. For example, two units GTX1060 6GB will work even if the cards are from different manufacture. However, a GTX1060 6GB will not work with a GTX1050Ti 4GB, as the GPU is different.

The temperature is depend on the installation environment, e.g. case fan, airflow. However a temperature below 105C or 235Fis workable for all ARKTEK graphics card normal operation.

There is limitation of 2 monitors only in Windows XP. Please upgrade the operating system to Windows Vista/7/8/10 for 3 monitors connection.

SLI (by NVIDIA) and CrossFireX (by ATI) are two of the more interesting technologies offered by GPU manufacturers.
In reality, they’re variations on the same concept: linking two or more graphics cards together in the same computer to help share the burden of high-end gaming and massively increase performance overall.
This idea is sometimes referred to as GPU-scaling. While each technology offers minor features they both operate in largely the same way: two cards get installed into your machine.
In addition to their PCIe connections to the motherboard, they also connect using a “bridge” cable so that they can rapidly communicate to each other.

Start by opening your computer case on the side that holds your motherboard and other components.
Look for your PCIe slot. It’s likely your motherboard has several similar looking slots – you want the longest one with the plastic retention latch on the end of it.
Now for the actual installation – carefully slide your graphics card into the PCIe slot, taking care to make sure its ports are sticking through those openings on the back of your case. You may need to use a little force to seat the card correctly but be careful not to strong-arm it too much. Make sure the card clicks into that little retention bracket on the end of the slot – normally it will do so, but sometimes you need to pull the bracket out a little with your finger.
Once the card is fully seated in the slot, secure the back of it to the case using the same mechanism that used to hold those metal brackets (usually either screws or some kind of latch). Finally, most gaming-class graphics cards require a dedicated connection to the power supply, so be sure to plug in your power supply leads if necessary.
Once the physical installation is complete, you’ll most likely need to log into your computer and install drivers for the new card. Until you do, your computer will default to a generic driver so don’t be surprised if you boot up and your machine is set to a low resolution – once you install the real driver that should fix itself.
Finally, one last safety warning: remember that your motherboard and graphics card are both circuit boards, and are therefore extremely sensitive to static shocks. Make sure to ground yourself either with a strap or by touching the metal frame of your case.

All warranty enquiries should be first directed to your initial place of purchase, depending on the initial purchasing store’s or retailer’s or e-tailer’s distributor’s warranty policy. To qualify for repairs or replacements under the warranty, it is required that customers provide proof of purchase. This should include the original invoice, documentation, or application form. Please note that a serial number is also necessary for a warranty check.
