Did a little more digging about the CM 412 Slim and CM 212 EVO cpu coolers. There is a progression of changes to arrive at the CM 412 Slim not to be completely confused with the 412S which is a 412 Slim with an earlier fan setup. Now that one is completely confused there are a couple of things to realize.
The 412S and the 412 Slim are the same basic cpu cooler when the fans are totally dis-regarded. The fins and heat pipes are the same for the 412S and the 412 Slim. CM has opened up the distance between the fins on the 412 series, which means less fins in the same distance to be used for the stacked fins. They have opened the distance between the fins to decrease the noise. Close together fins require more fan pressure to force air thru the fins and thus more noise. Increase the distance between the fins and you essentially get less noise in general.
Okay to fans on the 412 series of CM cooler. The 412S has a pretty slim single fan trying for added clearance for surrounding parts and pieces. The 412 Slim has two even slimmer fans than the 412S's single fan.
So what does all of that changing around get as a result. Well most likely not nearly enough cooling to push an FX-8350 very much in an overclock.
I don't normally like to see reviews of a cooler I am interested, in done on an Intel setup. The FX processors are HOT. Or make that really HOT. But this review I am going to link did the testing of cpu coolers on the Ivy Bridge 3770K processor and they run hot as well.

I particularly was interested in this linked test because of the number of coolers they did test and the fact that the cpu was overclocked to 4.6Ghz AND they tested the coolers at a normal Vcore for the 4.6Ghz clock but they then upped the cpu Vcore by a goodly amount to really heat the 3770K up. IT DID TOO.
Here are the cpu coolers they tested.
Cooler Master GeminII SF524
Cooler Master Hyper 212 EVO
Cooler Master Hyper 412S
Coolink Corator DS
Corsair H100i
Corsair H60
Deepcool Assassin / Alpenfohn K2
Gelid Tranquillo
Gelid GX-7
Noctua NH-D14
Noctua NH-L12
Scythe Grand Kama Cross Rev. B
Scythe Katana 4
Scythe Mugen 3B
Scythe Ninja rev 3B
Those five underlined cpu coolers were the ones I was most interested in seeing tested. Why? Well the much beloved CM 212 EVO was in the test along with the 412S (predecessor to the 412 Slim) which should give an idea of the 412 Slim compared to the CM 212 EVO. Well it does if you can reason logically outside the box. I say that because we pretty well know the H100 nor the H60 have enough cooling power to allow an 8 core FX processor to be overclocked by very much at all. IF the CM 212 EVO falls pretty far behind the H-100 coolers when the 3770K processor is pushed and tested, then you can be pretty much assured that no 412Slim has a chance to really cool an overclocked FX-8350 in a warm climate.
You can read all the hype for each cooler tested and then you will finally get to the real meat of the test article. The last three pages I believe it is. The lay the graphs all out and list the coolers in order of their "cool". At the lesser Vcore'd test at 4.6Ghz everything looks rosey at IDLE. Now look at the LOADED temps. Oops. Loaded changes things dramatically and quickly as to what cooler has any cooling brawn.
Ah the next to last page gets really good. They jumped the Vcore on up at 4.6Ghz to really make that 3770K processor put out the heat and it does. Look at how the coolers are ranked now with the the cpu at idle. Humh! Now look at the cooler ranking under load. Oops, the beloved CM 212 EVO is fading fast still. So too will the 412 Slim in all likelihood. And especially so when latched on top of an FX 8 core processor in a hot natural climate.
And then there is the conclusion page which I did NOT even read. I draw my own conclusions since I can read and comprehend graphs.
If this user can afford and has any access to some real cooling, then he needs to find it and use it or he is on a road to likely dissappointment in the speed he can attain with any chance for good temps and extended stability. Good forturne to you with air-cooling in your warmer climate.

EDIT:
I see the user had shown the CM 212 EVO is back in stock. No problem. Like I said the test article DID include the CM 212 EVO anyway. Same rules and outcome will apply.
END EDIT.
