4 out of 5 eggsNot To Bad

Pros: The heat sink itself is great cools great has copper piping that’s it for that

Cons: The setup is very confusing but did figure it out I do have 10 years of building computers but the instructions should be clearer. The fans on it anrt great they are held on by rubber things that slide on the heat sink wish they were plastic clips or something else they are not touching the heat sink either I think they should be for more cooling. But not bad for the price will probably go back to another brand but would buy again if needed and if the money is right

5 out of 5 eggsAlmost perfect

Pros: Cools infinitely better than stock FX-8320 heat sink. Keeps CPU near 40C at full load with good airflow. Got 4 of these on sale.

Cons: The fan setup is poor. The fan should be closer, to provide better cooling, or at least shrouded. the rubber mounts are not convenient, and there are no screw holes.

Other Thoughts: A great buy for its price.

5 out of 5 eggs750k @ 18.5 C idle

Pros: Great for the price.
Comes with pretty decent thermal compound.

Cons: None.

Other Thoughts: Shipped in a box that keeps the hardware separated from the heatsink to ensure there are no dings in the heatsink when it shows up. I have had to return heatsinks because of that before.

1 out of 5 eggsBeware about the fan!

Pros: The cooler itself does the work as the most other devices like this

Cons: The fan has just three pins and there is NOT a word about this in description! It is not silent at all and sounds like a rocket, I don't understand how it is possible to claim in specifications different ranges if the fan is not capable to be controlled by power management!

Other Thoughts: just purchased a fan with 4 pins from other seller, will definitely avoid this manufacturer in the future

5 out of 5 eggsCool: check. Quiet: DOUBLE CHECK

Pros: You will never know this thing is running.

The temperature capacity is FAR FAR higher than any OE cooler that I have worked with.

Cons: It's a little big, so check the dimensions of your case.

The mounting mechanism for the fan, using rubber pins, is obviously meant to absorb vibration. What it amounts to is a pain in the kiester.

Other Thoughts: The Hyper 212 EVO was strongly recommended to me by several other professionals for the following applications. I am very glad I went with the SinenX. My customers saved money and you can't convince me that the Cooler Master performs any better.

I had a custom-built security DVR in a customer's office that was transcoding 9 channels of full 1080 around the clock. The CPU was working so hard that the fan was awfully loud, and the case was exhausting frighteningly hot air. With this cooler the fusty air is still pretty hot, but the CPU temps are much more sensible and you can be within 20 feet of the machine without getting a migraine.

I used another one in a headless pseudo-server that lives in a smallish cabinet with a lot of other equipment. Even with push-pull fans at the top/right/rear and bottom/left/front of the cabinet and very little CPU load, the ambient was too high and causing the CPU to cook and the OEM CPU fan to run like a turbine. Since the cabinet was in a 12'x12' office where someone has to work 8 or 12 hours a day, they were going crazy from the noise. With the EFZ-120HA5 installed, you wouldn't even know there was equipment in there if it weren't for the push/pull fans.

I'm sure the Hyper 212 EVO is a very capable and very quiet cooler, but if you are sitting on the fence and $10 matters to you, get this one.

3 out of 5 eggsGood, but fan has a fatal flaw

Pros: Good mounting, solid build quality, even gave me extra screws and springs.

Cons: Fan is three pin and doesn't support pwm on modern systems.

Other Thoughts: The heatsink is solid and mounts very cleanly. I actually like it better than the coolermaster 212 it replaced (fan failed). It is not as heavy so my board isn't bowing anymore, and it has a much better and more solid mounting system. Now my issue, the fan is a three pin fan that has no pwm and therefore no speed control on my i5 / lga1155 system. I think that a cooler listed for these systems should have a pwm fan since you can still plug a pwn fan into a 3 pin board. That said I was so happy with the heatsink that i chose to just replace the fan on it and keep it. In regards to temps... this guy is only a couple degrees off what the coolermaster 212 did, when you consider it has one less heatpipe and less weight/material thats pretty good. I have a non=oc i5-2500 and under prime95 for 10 min I never went over 50c and i idle in around 32c.

4 out of 5 eggsGreat temps, few problems.

Pros: Fantastic Temps, Comes with the ability to add an additional fan for a push/pull config, and near silent.

Cons: Assembly is a bit of a pain, some quality control issues; a few of the nuts had damaged threads, making them near impossible to use during assembly, and unfortunately the AMD nuts are quite unique, so I really just had to muscle one of them on (They included one spare bolt, but 2 of the 5 had damaged threads.). And finally, the backplate was a little bit warped, I didn't realize this until I had tightened it down and realized that my Motherboard was quite warped, after loosening the bolts some it's returned to near normal shape, this is a pretty big deal, you probably could straighten it with a hammer, but...a flat back plate really is a mandatory.

Other Thoughts: Improved temps on an AMD Athlon X2 7850 Black Edition Kuma 2.8GHz from 28 C idle to 18 C idle, and 60 c 100% load to 43 100% load (was using a stock cooler).

Gave it 4 eggs cause to me, the temps are what really matter, but in terms of quality control I would give them a 1-3 egg score.

2 out of 5 eggsInstall is not easy

Pros: Comes with everything you need. Design is satisfactory. Copper heat tubes in direct contact with CPU instead of inside aluminum. Fan is quiet. Inexpensive.

Cons: What a mess it is to install, but i guess you get what you pay for. Parts needed for install are located in the opposite vendor bag. The fan is too big for the heatsink and is attached with rubber posts that wiggle out... I ended up zip tying it to the fins. The instructions were not clear and definitely needed because of all the "options" for CPU types. The parts were a guessing game when it came to figuring out which washer was what or things like what bag the screws for attaching the bracket to the sink were in. I ended up using the adhesive discs between the plate and the mobo and the metal washers for the top. My choice based only on logical processing not from the instructions. The face of the heatsink had hairline gaps between the copper and the aluminium. Easily overtightened. It was a guessing game as to creating even pressure over the CPU without stressing the board. Wished it could have used the very well designed asus mobo clip-in brackets for OEM AMD2/3 style heatsinks.

Other Thoughts: For its cost, it seems to work well once you get it installed. 97°F with an AMD PhemonII X6 (which is usually overvolted and runs hot by default). If you're doing a cheap update to an older PC this is still worth it. It is very tall so you will need a full sized case for this.
