I'd say your red screen was probably a direct result of the failed overclock and extreme GPU temps you were experiencing and the card may even be damaged at this point. Try removing any overclock, if the card is still functional, and if you're lucky enough that the card still works, don't overclock until you have sufficient case cooling to keep the GPU cooler supplied with the necessary inflow of cool air needed for it to do it's job. If you have good case cooling, including at least one intake and one exhaust, and preferably two or more intakes and two exhausts, then you're either...

I have not overclock anything yet i always check my gpu temp when im gaming and it never exceeds to 60c., I do have a aftermarket cooler for my cpu and it never reaches 40c even when im gaming for my case i have aerocool strike x one with 2 fans at the top. I do plan to oc but im still reading guides online.
No. Rear fans should not be intake. Your configuration is all screwy. Front, bottom and side fans should be intake. Top and rear fans should be exhaust, unless you have a top mounted power supply which changes the rules somewhat.
Side fans should be intake, however, your case has three front fan locations if you remove the front panel. I'd highly recommend using those before using any side fan locations. Actually, installing two front intakes in the lower two of the three locations there, and one side intake might be the best and cheapest option. These would work fine or you can get higher end PWM models if you wish:
