Any of these CPU coolers worth getting?

Its going to be summer soon and Australian summers can get pretty hot (not unusual for it to get up to 40°c), so I'm considering getting an aftermarket CPU cooler.

I'm expecting my CPU to start getting a lot hotter soon, plus I wouldn't mind upping the voltage so I can add the +.5 multiplier (to take it up to 3.6GHz).

I'm very restricted by room, so its been difficult finding ones to fit.

This is what I've picked out, tell me if you think any of them would be any good.

Here are my current temps:

Idle

Under load (these temps don't really look right (I thought they would be higher), have I done something wrong?)

Are you limited in height in your case or what?

Is your rear case fan a 120mm fan or capable of holding a 120mm fan? It may be worth it, if your budget allows, to pick up a Corsair H50 self-contained water cooling system.

It's not really "spending more on this PC" as much as it is investing on a CPU cooler that will work on future computers.

if you can find one.. Arctic cooling freezer 7 pro.. idk what they would fetch over there but here in canada one is about 35 bucks.. ish.. MAN are they a badass cooler.

they easily take my core 2 quad to the land of ice and snow.. figuratively speaking of course. runs fairly quiet too,

How about Hyper 212 plus? It's extremely great for its price.abuabed
