You definitely have at least a couple of issues going on here. First, the 3.4 duals run rather hot to begin with, but to save yourself money, try playing around with a couple of items in your BIOS first: 1) Make sure that any dynamic overclocking settings in your BIOS is turned off. Those programs almost always cause reliability/stability issues. 2) If the first doesn't help much, try lowering the voltage -in small increments- of your cpu core. Alot of people don't know this, but some processors in conjunction with certain mobos actually like less than the spec voltage regs. My 3.0 HT cpu overclocked to 3.37 is more stable at a higher voltage on my 945 msi board than my friend's cpu, same processor, same overclock ratio, but on his Abit board, his became stable when he turned his voltage down below spec. A can of air to blow out the fan is also a cheap possibility. If none of these help, and your fan is simply too loud, you have several options, some of which were stated above: 1) You have to cool down that processor or else it will burn out quickly, so a better heatsink/quieter but faster fan should do the trick (keep in mind that it's often best if the cpu fan runs constantly -processors like engine manifolds wear when temperatures fluctuate- 2) You could go water-cooled, it's very quiet (usually) in comparison to heatsink/cpu fan combos, and nowadays, is comparable in price to some of the better cpu fans out there. 3) If you want to raise the eyebrows of your roommates or guests, you could 'mickey mouse' your machine in many different ways like the pair stated above 4) Although very spendy, the stability and longevity that a sealed thermal case will bring may outweigh the cost in many a gamer's eye. The prices for sealed cases is still very high, but if you need some serious cooling power without all the noise, a fridge case is the way to go 5) Lastly, I would not recommend using a vacuum cleaner on your pc. As someone stated above, the static discharge could have any number of unhealthy effects on your hardware.
