Would it be necessary to buy an aftermarket heatsink to OC an e2140?

[Ichigo]

is it necessary assuming I'm looking for it to hit 3Ghz?

And if I really should buy one, what do you recommend? Do you also recommend AS5 to go along with it?

If you're looking to hit 3 Ghz+, you'd want a good aftermarket heatsink. The best one for the money is probably the Scythe Ninja Rev. B; it comes close to the performance of the best air coolers on the market, but only costs $40.

A good aftermarket HSF is always a good idea.

But I am running mine at close to 3GHz with the stock HSF with no problems.

But... I have a side fan blowing directly on it.

Intel ships all the CPU's with the same HSF, including the 3GHz ones, so I guess they have full confidence in them.

In your case it would be more important to actively cool the NB, since you will be hitting high FSB numbers in excess of 400MHz.

I'm in Canada, so the Scythe would cost me $50 before shipping + tax, which makes my budget build a complete paradox. What about the Arctic Freezer 7 Pro? It'll only cost me $30 at a local shop and I've seen some graphs that show the stock thermal paste to be even a bit better than AS5. Additionally, I wouldn't need to buy an extra fan.

By the way, I'll be running the e2140 on the EVGA 680i TR series motherboard (the one with the quad core issues that don't affect me) and 2GB of OCZ DDR2-800 Gold XTC RAM. Is the NB hot on the mentioned motherboard? What kind of cooler am I looking for to cool the northbridge anyways? Any tips on overclocking my setup are appreciated as well.
