This will be a short comparison between Arctic Cooling Freezer 64 and Cooler Master Hyper 212 Plus. The CPU to be cooled is quad Phenom II. I bought a Phenom II X2 555 Black Edition, and not only it unlocks to all 4 cores, but also overclocks to like 4 GHz, quite simply the best CPU in price vs performance I've ever bought It also runs stable with C'n'Q on and voltage on auto, probably thanks to smart automatic voltage by ASUS M4A87TD motherboard.
Now, I've had this Hyper 212 sitting in its box for quite a while but finally got to installing it today. My old cooler, Freezer 64 which I had from my previous PC build isn't bad, but not enough for overclocking a 4 core Phenom II.
Hyper 212 Plus:
Temperatures at 3.2 GHz (no overclock)
Freezer 64 / Hyper 212+
Idle (downclocks to 800 Mhz): 38C / 35C
After 20 minutes of Prime95: 54C / 47C
20 min of Prime95 + Furmark: 59C / 51C
OK so even with the old Freezer 64, temperatures are acceptable. The max temp for this CPU is 62C so 59C is a bit close, but no game is optimized enough to give a consistent 100% CPU + GPU load like Prime95 + Furmark combo does (loading GPU generates more heat in the case).
Note that fans aren't set to run at 100% all the time, but rather ASUS "Q fan" is on in BIOS, meaning fan speed depends on temperature. When testing with Prime95 + Furmark Freezer64 already maxes out at 100%, but Hyper 212 does not.
Temperatures at 3.8 GHz
After 20 minutes of Prime95: 60C / 55C
20 min of Prime95 + Furmark: 66C* / 59C
*With Freezer64 I didn't finish full 20 minutes. Temperature kept rising and I didn't want to fry my CPU.
In the end I decided to drop the frequency to 3.7 GHz for everyday use, both to reduce the temperatures and because my motherboard seems to automatically disable Cool and Quiet if CPU is higher than 3.7 GHz (likely due to increased voltage).
I actually like C'n'Q because in Windows it automatically downclocks to 800 MHz or 2.1 Ghz (depending on load) = less power usage, less noise, less heat, and you help teh planet by using less energy (And it runs stable despite OC).
About Hyper 212
Now a short review of things I didn't like about the Hyper 212+. The installation was somewhat annoying. You can see the instructions in this official (?) video:
Well, I didn't have a long and thin screwdriver like that, and couldn't reach the screws with a regular screwdriver because the heatsink was in the way. I ended up having to do it with my fingers, and afterwards with a screwdriver sort of from the side, not fun.
Second, the base of the heatsink is rough and there are gaps where the heatpipes are inserted, I tried to fill them with thermal paste but of course it would be nice if it was smoother.
Finally,this thing is much louder than I thought. I can understand it would be loud under load, but even at low RPM it's got this annoying buzzing noise. Maybe my (old) case is partly at fault due to vibrations or w/e but this fan definitely isn't as silent as I thought. Maybe I can replace it with another fan in the future, since it's simply clip on fan that can be switched easily.
For the good things, well, this cooler definitely doesn't have the best performance, but it might have one of the best price vs performance ratio, and it's probably one of the best cheap coolers that still does a great job. You can find out a bit more about Hyper 212 on my page about Phenom II coolers.
Next I plan to replace my old case with something cheap like Antec 300, hopefully that will help more with cooling my CPU as well.
