Is Arctic Freezer 7 Pro good for Quad core CPU?

I see many people are trying to get Q9550.

I am also getting Q9550 but im not sure whether I should
buy Arctic Freezer 7 Pro or buy something else.

it looks like Arctice Freezer 7 Pro works almost perfectly with dual core cpu such as E8400. At newegg, there are some heavy worshipping going on. On the other hand, I can rarely see any quad core users in the reviews.

So how is Arctice Freezer 7 for Q9550 assuming that I am going to overclock it to 3.4? Should I stick with it or should go for more expensive cooler?

It's a good cooler if you have space constraints, but if you can fit a 120mm fan tower in your case it will be better. The freezer pro 7 will probably accommodate that OC with that processor, but it will definitely be warm. I'd spend just a few more dollars on a xigmatek s1283, or the s963 for a 92mm solution. Those, I think, are the best bang for the buck.

probably not as warm, but definatly warmer then a S1283 or a sunbeamtech core-contact freezer.

ACF7P is a good cooler even for overclocking around 3.2GHz using a quad like Q6600.

BTW, ACF7P is applied with either MX-1 or MX-2. I suppose all the new ones are pre-applied with MX-2. I got this info off of Arctic-cooling.com
