How to stop my graphics card from overheating?
So, if your graphics card is overheating, it’s likely that your computer case isn’t getting enough fresh air or access to cool surfaces. The solution might be as simple as moving your computer away from the wall and hosing it down with an “external bay” fan. If you don’t want to disturb your set-up more than necessary, try giving yourself a little breathing room by turning off some of those peripherals (PSUs, fans) on the backside of the card. Simply open up Antec 300 prototype PC case and remove any 2x 120mm outtake fans from inside the chassis. This will now allow for more airflow throughout performance components such as coolers and GPUs in these tight enclosures like Antec 300 or Antec Eleven Hundred.
If you are still having overheating problems, it might be time to consider getting yourself a better CPU cooler. This will allow you to run the CPU at a lower voltage and hence reduce heat output.
Also, it is recommended to keep your computer up-to-date with all the latest drivers and BIOS updates for your motherboard.
