Hi, I just bought a diy computer,
intel i5-4430
gigabyte ga-h87-d3h
leadtek gtx650 2g
coolermaster extreme2 625 psu
wd 1tb
sharkoon t28
i am completely unsure on how to overclock and i am also worried about cooling as i am using the stock intel heatsink and cpu fan.
How do i overclock and not damage the motherboard?
can anyone recommend a cpu fan that is value for money and small enough to fit in the case? Have any of the above listed components have any known issues? thanks!
