A compact spiral heatsink for those with more moderate cooling needs, the EFZ-92HA2 is currently the best selling retail heatsink in the world along with its bigger sibling, the EFZ-100HA2. Over half a million units shipped monthly, this is a great heatsink for anyone looking to replace their stock cooler with a little more oomph and a little less noise. The EFZ-92HA2 is just 56mm tall with the fan and fits in any 2U rackmount case along with just about any small home theater or small form factor case out there, it's just that small! A universal mounting bracket supports the widest range of current AMD and Intel sockets, including the latest multicore Phenom and i3/i5 processors.

SilentX has included an Effizio 92mm fan with 3rd generation fluid dynamic bearings for years of reliable performance and no need to purchase any additional fans. The installation process is easy with a typical install time of under 10 minutes and does not require the removal of the motherboard.

1 out of 5 eggsThe worst thing I've bought in a long time

Pros: This is one of the cheaper heat sinks it is fairly small, it comes with an AMD AM2/3+ to intel LGA115x/775 cooler adapter, and It looks cool enough as a paperweight.

Cons: This cooler has some serious faults:
The fan on this thing is not PWM, so it blows at full speed all the time, the contact plate on it is REALLY rough, so the contact between the CPU's heat spreader and the heat sink is not good enough, the fins on it are SUPER flimsy, a light tap on a hard surface can bend them, and, at least on the one I got, there were some fins that were stuck together.

Other Thoughts: This CPU cooler is utter trash. I thought this would be enough to cool an Intel Core i5 4690K at stock speed better than the stock heat sink. I was wrong.
At idle, temperatures stay at around 38-43ºC/100-110ºF, and under load it went all the way up to TJ Max (100ºC/212ºF) and it starter to throttling by about 25% to avoid burning itself to death, unlike the stock cooler, which had the CPU at about 94ºC/200ºF under load.

I would NEVER recommend this product to anyone, unless you'd like to try an AMD cooler on your Intel CPU and don't mind paying full price for a piece of plastic.

3 out of 5 eggshope the next one is better

Pros: low profile and quiet

Cons: arrived with heat sink blades bent. Mnfctr box un harmed so it shipped from factory like this. Poor quality control. I had read a of a few instances of this in reviews but tried it anyway.

Newegg gave me an RMA automatically. I asked for a replacement. Item was out of stock so the gave a refund instead. Chat found that it was in stock now so I ordered a new one 3 day shipping (shipping charge refunded by Newegg).
I will let you know when I receive the next one if it is okay and how it works.

1 out of 5 eggsWorse than worthless

Pros: None, unless you want to get practice changing heat sinks, cause you will put it on, and take it right back off.

Cons: This looked similar to another brand, and it was cheap, so i thought i'd try it. Big mistake. My dual core AMD usually runs a bit hot. Around 130 F or 50 C. With this product the CPU temp went right past 130 (50C) and was still going up at 148 when I powered it down. Put the stock AMD heat sink back on and it's back to running 126 F right now. As other have said, fins are very flimsy. A copy cat product that just doesn't work. Now to see if i can RMA the junk.

Other Thoughts: Penny wise and dollar foolish. I should know that when the price seems too good to be true, is probably is.

2 out of 5 eggs

Pros: light, "low profile"

Cons: Well...the negative reviews were true: I couldn't get the assembly out of the box without mashing some of the heatsink fins to the point that they made contact with the fan. I used very light pressure. The only way to pick it up seems to be by the blades of the fan itself. Additionally, the sink fins hang over the closest memory bank of my motherboard (MSI A55M-E35). I think the RAM modules would still fit if I placed them before the heatsink, but that will never happen. ...

Other Thoughts: comically, this "low profile" cpu cooler is 1.5x-2x LARGER footprint than the stock cpu cooler (AMD A8-5500 Trinity Quad-Core 3.2GHz AD5500OKHJBOX), and the vertical difference is negligible. I'll never know if the silenx fan is as wonderfully quiet as reviews have stated. I trust that it is. I don't care.

it's possible to bend the fins back so that they don't interfere with the fan, but they look awkward at that point and, as I never got to mounting the thing, I've no idea what effect, if any, it has on performance/sound.

the 2 eggs is because I believe it's quiet. the deductions are for flimsy design and overlarge diameter heat sink on a cooler specifically designed for HTPCs (e.g., mircoATX and other space cramped applications).

3 out of 5 eggsYou get what you pay for

Pros: Any noise it makes is not noticeable inside the case.
Solid install feels very secure- too secure.
Comes with multiple pegs, a mount and some thermal gel. The thermal gel comes in a small, plastic baggie.

Cons: The fins are incredibly flimsy. To the point of if you hold them (as they are the majority of the surface) you WILL bend them. Install Carefully.

The unit has a very, very rigid bracket that mounts to the stock AM3+ socket. I installed it while it was placed on a static mount flat on a table, no flex- and I was still kinda scared I was going to break the board with the pressure I had to apply to get it seated.

As the title states, you do get what you pay for. Don't know what I expected out of this unit, but I think I'll be using my stock heatsink that came with my CPU until I can get a better quality cooler.

Other Thoughts: Brand new PC build featuring an AMD FX-4130 Zambezi 3.8GHz Socket AM3+ Quad-Core Desktop Processor - the CPU runs at about 50-55 degrees Celsius under this cooler and no load. This can easily jump to upwards or 65+ under a basic load and gets pretty warm while running any more demanding games.

This was under stock conditions- but the ASUS M5A97 LE R2.0 AM3+ that I bought to pair it with comes with some pretty robust OC features, and I chose to bump the CPU up to 4.2 with the basic OC utility, which the board claims to be a relatively stable and safe clock. The temps remained pretty much the same with the OC enabled.

2 out of 5 eggsNo any better than the OEM

Pros: It fits, easy installation, and comes with grease...

Cons: Won't cool any better than the one AMD sent with the processor.

Other Thoughts: Fins are realyl thin and will need straightening after installation.

5 out of 5 eggsExcellent budget heatsink.

Pros: With the stock heatsink installed on an AMD Llano 2.7 GHz Unlocked Quad Core APU the temperatures in idle were around 20 Celsius and under heavy load at 55.
After installing this heatsink and sealing with some Arctic Silver 5 paste temps at idle were around 15 Celsius and around 45 under heavy load.

Cons: I wouldn't recommend this heatsink for overclockers or for CPUs clocked above 3.5 GHz as the temps can get pretty high at that rate.
