At your ambient temperatures, I'd use an Afterburner "fan profile" and NOT a fixed setting on the fans, for those days it gets hot - and I would avoid overclocking ANYTHING.
Make sure the fan profile hits 100% at no higher than 80 degrees C when you set it up, then I'd say have it drop 20% for every 10 degrees C below 80.
Where the heck are you that you see temps in the 50 C range (122 F for those that don't grok Centigrade)....
I live in Rajasthan in India and this much temperature is normal here during summers, it's 9:30pm now and still the temp is 42degree Celsius.Make sure the fan profile hits 100% at no higher than 80 degrees C when you set it up, then I'd say have it drop 20% for every 10 degrees C below 80.
