I am planning to upgrade my PC soon to a SB set up. Currently these are the parts I am thinking about upgrading to: CPU: i7 2600k Motherboard: Gigabyte GA-P67A-UD5-B3 RAM: Corsair DDR3 Vengeance, 1600, CAS 9-9-9-24, XMP, 1.5V HS&F: Noctua NH-D14 These are all fine, but I am concerned with the motherboard. I know it's a good motherboard, but I think it is a little out of my price range for the non-extreme type of over-clocking I am planning. (Around 4.5 GHz) The main reason I went for this motherboard is that it has 3 case fan headers which would cover all of the fans in my P182 case. If it wasn't for that I would have gone for the GA-P67A-UD4-B3 as this is more than adequate for all my other needs. Around £60-£70 more just for an extra fan header is a bit much to swallow though. With the amount of people on here that test many different motherboards and are much more tech savvy than me. Is there another board that anyone knows about at around the price, performance and reliability of the UD4 but with the extra fan header? If not I will probably save the cash, get the UD4, and put up with the fan on the rear of the case running full pelt all the time. It will still be quieter than all three Silent Typhoons running at full pelt. I should mention that I will not buy ASUS motherboards due to a very bad customer service experience I had with them, and by extension I won't touch ASRock either. The second bit of advice I need is regarding CPU temps. What is a safe temp to run a 2600K at for a permanent 24/7 OC?
