Need advice finding a CPU cooler that will fit in my computer

I am looking for a new CPU cooler. At this point in my PC's life, I don't feel that the CPU's stock air cooler is cutting it. I've been hunting for a better CPU but it's been a struggle to find a better cooler that will physically fit in my computer.

I feel that part of the problem is that while I'm reading the heatsink dimensions on websites like Newegg, I'm not sure what those dimensions actually mean. Perhaps the cooler's I'm rejecting based on their dimensions would actually fit? Are many of them more slim in form closer to the CPU and RAM and get bigger as they project outward from the motherboard?

I'll start with my system specs (built in 2010, GPU upgrade late 2014)

NZXT Gamma Case
Gigabyte GA-M68MT-S2P AM3 Board
AMD Phenom II 965 BE @ 3.4 GHz w/ Stock Cooler (undervolted)
OCZ 600W 80+ PSU
MSI Twin Frozr GTX 760
8 GB G.Skill Ripjaws DDR3 RAM
1 TB Seagate HDD
5 Case Fans - One in back (Exhaust), two top (Exhaust), one side (Intake), one front (Intake)

Here are some measurements I took. This is how much room I'd have available relative to where the CPU is located:

Between side panel and motherboard: ~193mm (168mm with a case fan on the side panel)
Between RAM and the back of the motherboard: ~93mm
Between top of motherboard and stuff below CPU: ~120mm
Height of G.Skill Ripjaws RAM next to CPU: 40mm
Motherboard CPU Cooler Weight Limit: 450g

If I can find a better CPU cooler, wonderful! It would be a bonus if it would allow for some overclocking.
 
Solution
For a maximum height did i find this:"168,5mm". Get something under that like the H7 mentioned above. Or a 120mm aio watercooler like the Corsair H60.

The Cryorig H7 looks like a good solution to my cooling problem, but the TechPowerup review says the heatsink alone weighs 577g. Per the Gigabyte website, the heaviest cooler the board can handle can't be more than 450g in weight (just added this info to the original post).

If I got this cooler, I could try and solve the weight issue by using a pair of wire ties to somehow support the free end of the cooler from the top of the case.

I've thought about getting the Corsair H60 water cooler, but I feel that would introduce more points of failure to my system, be it the pump dying or a leak forming.

I ended up ordering the Cryorig H7. Once I get it mounted I'll report back here with results.

Right now as I'm surfing the internet, HWInfo64 says my average "CPU #0" temp is 38 degrees C with a minimum temperature of 26 degrees C and a maximum temperature of 58 degrees C (that was during a CryEngine-based MechWarrior Online gaming session). As I'm typing this now, my current temperature is 43 degrees C.

I just got the Cryorig H7 yesterday. I will probably install it tomorrow or Sunday.

While I was waiting for it, I realized that my motherboard/EasyTune 6 was using a lousy fan speed/temperature curve for my computer. Once I adjusted that I got better temps with the stock heatsink. My computer didn't break 55 degrees C while gaming. Right now the temp is at 44.

I have to figure out how to start ET6 when Windows boots that way I don't forget to run it each time. Otherwise, is there a better program for automatic CPU fan speed control?

Can open taskmanager->tab boot->click file->new task-> add easytune (use the proper name)




Look first in the bios for settings regarding the fans.You could also try speedfan,but haven't used it for a long time so can't say how that works these days.

So installing the Cryorig H7 was quite an adventure, and I learned a few things.

When I pulled the stock AMD heatsink out of my machine last night, my CPU went with it! I soaked the thing in 91% rubbing alcohol overnight and trying separating the the CPU from the heatsink with floss, a razor blade, and a pocket knife. None of that worked. What I ended up doing is heating up the heatsink with a hair dryer until the copper contact plate reached about 60 degrees C (monitored with a concrete/asphalt testing thermometer). I tried twisting the CPU off the plate as recommended in my research, but that didn't work. Finally I pried it off with a flathead screwdriver. It came off with a pop! I was afraid I ripped the CPU free of its heat cap, but fortunately it all came off in one piece. I proceeded to clean the AMD thermal paste off both my old heatsink and the CPU. I also fixed some bent pins with a jeweler's screw driver.

Installation was a bit difficult as I elected to not remove the motherboard from the machine. Instead, I removed both of my RAM sticks and the GPU, and disconnected the data cable for the CD drive and the power cable for the motherboard. With the case on its side with both side panels removed, I applied a pea-sized blob of the supplied Cryorig CP7 thermal paste to the center of my CPU. I then positioned my case half hanging off the table so I could seat the H7 properly on its new mounting screws and screw it to the board from the backside of the motherboard. Even then it took shoving my fingers into the tight spots between the H7 and the motherboard to get the mounting bracket on the H7 positioned properly on the screws. I tightened down everything equally and started putting my machine back together. I even rerouted a few cables to clear up the inside of my case.

I fired up the computer hoping that all went well and now I'm typing this using my cooler CPU. Guess we know how this ended :)

As I'm typing this post, my CPU temperature is 26 degrees C! Wow, what a difference from 44 degrees C doing the same thing! I'll post more temperatures as I spend more time with my new cooler. Maybe I'll attempt some overclocking later.

I do have a small concern with the fan that came with the heatsink. It has a small wobble a low RPMs, but near max speed the wobble disappears. There is no grinding, whining, or any mechanical noise indicating a problem, and the fan is actually a little louder than the AMD stock heatsink (it whooshes more even at 512 RPM out of about 1600 RPM max).

Anyway, here's what I learned:

-Remove stuff around the CPU when replacing the heatsink and/or CPU. It will make stuff easier!
-If you get a CPU heatsink with preapplied thermal paste, remove the past and use your own. It appears that manufacturers who provide thermal paste preapplied add too much, causing the paste to ooze out and causing problems with the processor being dreadfully stuck to the heatsink.
-Having a case where you can access the back of the motherboard to get to the CPU heatsink mount is a major convenience. I'm glad my NZXT Gamma case has this feature!
