Hi all, basically i m not a very technical guy when it comes to hardware and graphics card was looking to try some overclocking to make full use of my 4870x2, can someone help me with this qn? 1) If I am gaming like 5-6 hours, is it safe to set the fan to 100% throughout the whole time? will the fan like burnout if i do this too often? 2) What is the normal or optimal temperature my graphics card should be, i m getting 70'c now when i m running a game like say warhammer online 3) Is there any threads that really teaches me the very basics of overclocking or maybe some websites that sort of makes things simple to understand? 4) o and if possible, can someone like recommend me some safe specs for overclocking. Something that is reasonably safe.
