3 out of 5 eggsNot quite cool enough

Pros: Very quiet; just what I had hoped for to do my audio recordings with. No fan noise in the background.

Cons: Not cooling enough for my usage. I have a AMD FX-8370 which is overclocked and just watching a video causes the CPU temperature to shoot up to over 60C. I tried to do convert the format of a video and the computer shut itself off to protect the CPU after less than 30 seconds. This also happened when I was simply trying to import photos into my photo organizer, ShotWell.

I tried the converting the video again with my overclocking removed and within 20 seconds my CPU was up to 68C; which is when I stopped the conversion. Without overclocking, just idling, the temperature is setting at 40C, and after watching a 3 minute long video the temperature was setting at 56C. If you have an AMD FX-8370 and are just doing text editing, and casual web browsing then this could work for you; but if you have an AMD FX-8370 then you are not just doing text editing, and casual web browsing. If your CPU uses 125W of power spend your money on something with at least 4 heat pipes on each side.

Other Thoughts: I carefully followed the installation instructions which stated to spread out the thermal conductive paste, and was sure to make the surface smooth. This is could have been a bad idea since if a small void was present then it would have trapped air and reduced the paste's effectiveness. I'm planning on removing the fan and paste, then reapplying in a five drop pattern. If this fixes the temperature problem then I'll update my review (or if editing isn't possible, I'll post another, if I can).

3 out of 5 eggsCould use a better manual and fan

Pros: Excellent cooling potential,

Cons: Included fan is not inherently that quiet, rubber holders are awkward to mount, and instructions are decidedly unhelpful.

Cooling stack is a bit tall for smaller cases, make your measurements first before you buy.

Other Thoughts: During install if your CPU socket is near to your RAM slots (typical on uATX motherboards) install your RAM before you mount the cooler. The cooler hangs over the slots and you'll end up having to un-mount it to get your RAM in.

Additionally, don't take off the backing for the non-conductive stand-offs except on the side facing the nuts.

2 out of 5 eggsMissing backplate, loud fan.

Pros: Fits an older Enlight midtower case perfectly, comes with heatsink paste. Well built.

Cons: Backplate necessary to attach the unit to my motherboard was missing from the box. Fan has only three pins, your motherboard has to support voltage control. Instruction manual could be better.

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.
