Alright guys, under the tree this year for me was a brand new Corsair H60, and some Noctua thermal paste. Rushed to install my new cooler and booted into Windows to check the temps...they were higher than usual. Checked the fan was plugged in and some other rubbish stuff, but I had to re-seat the block - it was only touching half the CPU! Now properly installed, my 2500K is much cooler; 30 idle and 45-48 whilst broadcasting and playing Killing Floor (50% usage). Now, I also recieved a new SP120, so I plan to have a push/pull config, but I want some advice. Currently, the fan is pulling cool air from outside and pushing it through the rad. Is this efficient for the rest of my components? Also, with both of the fans does it matter which is pushing and which is pulling? One last question, would it be worth using the Noctua pasted or dealing with the one applied by Corsair? So far I'm really impressed, for only £60 it seems like a great deal, even though it was a tight squeeze in my case for some reason...anyway, advice shall be appreciatted!
