will Cooler Master Hyper 212 Plus/Evo fit in this mid-tower case+micro ATX mobo? if not then plz recommend other HSF

as the title describes, good sirs

some background story:

I'm planning to upgrade to i7 3770k, but I read everywhere that the stock HSF is sucked. afraid of my future CPU longevity, I want to buy an aftermarket ones. Cooler Master Hyper 212 Plus/Evo (is there any difference between Plus and Evo btw?) is often mentioned everywhere as the best bang for the buck. but after reading the dimension and see some pics, I think it will not fit into my rig?

my spec:

case: Simbadda SimCool SMC-5817
pretty much unknown brand in the West, this is a mid-range price for casual users to mid-range non-enthusiast gamers. full metal casing, except the transparent part on the side panel is made from plastic. it comes with its own (not pure, but up to) 430w PSU, but I switched it with Corsair CX600, 600w, 80 plus bronze, builder series v2 a long time ago. plz refer to the attached pics for dimension and air flow.

mobo: Asrock B75M

it's a micro ATX form mobo. and it's a B75 chip. bought it when I was still very new to computer stuff, so it was kinda randomly bought. I only knew Asrock is good, the price was okay to my wallet.

I know I wouldn't be able to OC the i7 with this. but I don't mind, I'm pretty much a casual user, I don't understand well how to OC, though I'm interested in it. the only stock available at my local store for LGA 1155 i7 is the K series one. I'm fine with this, only around 6$ higher compared to standard 3770 price. the extra 1000 Mhz is cool anyway. I don't have more money to buy a Haswell, because I have to buy a new mobo then. so I'm kinda stuck with my current mobo, which I think is not too shabby?

Okay, now let the pics speak:

so what do you think, good sirs and ladies? will CM Hyper 212 Plus/Evo fit? I think it will not, since my case width is only 18 cm. if that's the case, then what good brand and type of HSF will fit? the smaller ones, I think. it could be another type of Cool Master or other brand, as long as it's got the same good quality, ie. achieved low temp will be the same, and same/close price range (slightly higher is okay) with that Hyper 212.

I know there are a lot of brands and types out there, so many that I'm overwhelmed, I don't know where to start. so I thought I better ask you guys and girls, user to user. because users know best by experience.

also I wish for the HSF to be not too hard to install. of course, I'll have the store guy installs it for me on the first time purchase. but for instance, a year later, I might want to clean my case and the components, I hope I won't having too much trouble in disassembling and reassembling, and applying TIM on the HSF.

btw looking at the small sized case and mobo, by installing a big heatsink hanging over there, won't it add extra heat or blocking air flow, coz it's using extra space inside the case? just thinking out loud.

also, the fan TDP is important. as I've mentioned above I'm using Corsair CX600 along with these components below, so I hope my PSU can supply enough power.

- MSI GTX 970 Twin Frozr V
- internal HDD Hitachi 500GB 7200 RPM (upper one in the pic)
- internal HDD Seagate 1TB 5400 RPM (below one in the pic)
- LG DVD-RW (seldom used nowadays)
- soon-to-be-bought i7 3770k
- soon-to-be bought RAM Corsair 1600 4Gb x2. I think I'm gonna buy the standard chip form ones, not the ones with fancy heatsink, as I'm afraid it'll hinder the HSF? there's no differences in performance, right? standard and with heatsink. the heatsink one is only good for OCing I think, which I will never do. besides the standard ones are cheaper obviously.
- 2 standard 8 cm fans: 1 on the side panel (came with the case), 1 on the bottom front (random brand cheap fan). both are fast.
- 2 standard 12cm fans: 1 on the side panel (random brand cheap fan, kinda slower just a bit compared to other fans), 1 on the back (came with the case, fast)
- 1 better and faster Deepcool 12cm at the front
- sometimes I plug in two external HDD 1 TB USB 3.0 (watching movies, copying/moving files, never while gaming)

so, what kinda low temp I would get with an aftermarket HSF? idle 20-30C? full load 50-60C? as I've mentioned a couple of times above, I won't do OCing, or rather my mobo won't allow it maybe a measly 400Mhz up from the BIOS, but again I think I won't do this anyway. I think this i7 is already fast enough for now? well, I'll do it 2 or 3 or 5 years later maybe, when newer games are already too demanding for my rig

for reference, my GPU temp on idle is around 33C when the AC is on, 35-37C when the AC is off. on load (gaming),I've seen 65-67C the highest, regardless the AC is on or off. the temp is actually lower when I play Tomb Raider, and higher when I'm playing The Evil Within. obviously graphics-wise TR is more complicated than TEW, but again TEW is badly optimized anyway. btw is this GPU temp good or... not so good?

my i3 2120 temp is around 38-41C when the AC is on, add 2-3C when the AC is off. on load (gaming) I've seen 70-75C the highest. I use stock HSF as the pic shows. this bad temp is my fault. recently I cleaned the heatsink, then just put it back onto the CPU without cleaning the old TIM, and reapply new TIM. I thought I'm gonna sell this i3 and get i7 soon (2 days top, depends on the reply here though) anyway, why bother as for the temp b4 cleaning the heatsink, I don't know. I became educated in monitoring temps just recently

I got all temps through MSI Afterburner. I'm not sure if I can trust it? what's better program? I've read RealTemp, CoreTemp, not sure which one is better.

thank you. awaiting good replies
