Re: Processing Speed.
A radiator and two giant fans won't do you any good - you see, your computer needs quite a lot of fans if you even wish to overclock past 2% of the processor's speed. Here's what the fan setup should be:
At the very least, one fan in the front (though preferably 2) at the size of at least 80mm; at the very least, two fans in the back the size of 80mm or one fan the size of 120mm. This is crucial: whatever the setup, there must be a low air pressure in the casing, meaning there must be more air being forced out than air being forced in. If you have two fans in the front running at a higher speed than the two fans in the back, your case will have a high pressure and that will cause over heating. The CPU fan must be extremely good (not talking a cheap $20 - more like in the range of $40-$50) and you must apply the right amount of thermal compound.
That's just a small bit of it... though if you don't have all of that done, then theirs no way you can get past 2.25GHz without overheating.
Happiness is not about being perfect.
It is about seeing beyond the imperfections.
