i5 fan for moderate OC?

[Auraomega]

I realised how much I've overlooked getting a fan for my new build, been looking at some reviews but I can't tell what's good price : performance and fits i5.

I've been suggested 2 things so far:
Coolermaster Hyper TX3
Arctic Cooling Freezer Pro 7 Rev 2

After seeing a comparison of coolers I've had a look at the Zalman CNPS9500 with bracket.

Now though I'm totally confused what I should/shouldn't get; so I come to yee, oh cooling board, for some friendly advice It needs to fit i5 (obviously), and it needs to fit in my case (NZXT Lexa S), if the company has a history of supporting coolers for new socket revisions, that's also a bonus. My budget allows ~£20 but if a significant boost in cooling power/drop in sound can be achieved for a little extra I'm willing to scrape the money together.

For that budget I think the Freezer 7 Pro is about the best your gonna get. The comparison you linked to is for a completely different socket to i5, which can have a suprising difference to cooling performance in some cases. You'd be better off find a comparison when theyre actually being used on i5 processors

Ah ok, I just assumed they would all be the same difference because heat is heat

I'll probably go for the Freezer 7 then, I can always upgrade in the future if I need to.

EDIT:
What about the Coolermaster Hyper 212 Plus, it's in the same price bracket and reviews look good for it... unfortunately I can't find a single review comparing the Freezer 7 with the Hyper 212, I can find different reviews from different places, but apples and oranges on systems means the results are useless to me.
