A compact spiral heatsink for those with more moderate cooling needs, the EFZ-100HA2 is currently the best selling retail heatsink in the world along with its smaller sibling, the EFZ-92HA2.

The EFZ-100HA2 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 100mm 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.

5 out of 5 eggsLow cost low profile cooler

Pros: Cost, compatibility, height from cpu is less than my more expensive low profile cooler.

Cons: Can be a little loud.

Other Thoughts: not for a 125 or 130 tdp chip, 100w may be too much.

3 out of 5 eggs3/5 bc

Pros: Fit my 1155 socket fine, fan works and still works after over a year ordered it for under $10 free shipping 5-7 day shipping and showed up next day.

Cons: the fins on the cooler are big, the cooler sits very low and is wide.

Other Thoughts: I had to bend one side of all the fins so that the cooler would fit because my ram was getting in the way. Still does what its supposed to atm running a loaner i5 at 3.8ghz and temps even under heavy loads are always in a safe zone.

1 out of 5 eggsSilenX EFZ-100HA2 100mm 3rd generation fluid dynamic bearing Effizio CPU Cooler

Pros: Inexpensive. Low profile design.

Cons: Didn't open the box until a couple days after receiving the cooler. Box is perfectly intact, not even a scratch on it. Unit inside is not so fortunate.
It looks like someone hit or dropped this unit, causing almost 1/3 of the fins (which are very thin and flimsy) to become bent or misshapen. Kills the ascetics. The fan still spins without hitting any, but it looks like Quasimodo's face.

Other Thoughts: Would RMA but not not sure it's worth shipping back for a $13 refund.

1 out of 5 eggsSilenX EFZ-100HA2 100mm 3rd generation fluid dynamic bearing Effizio CPU Cooler

Pros: price is cheap

Cons: 1 not quiet!as loud as the sock cooler when they are running at the same rpm

2 does not lower the temperature, even at max fan speed (2400 rpm)

3 poor installation manual, very difficult to secure the latches, especially when there is no clear instructions on how to do so.

4. it has 3 pin connector, many motherboards can't control the fan speed with 3 pin connector
5. the brand name "SilentX" miss led people to thinking their product would be at least quieter than the stock cooler, but they are NOT!

given that this cooler is louder than stock cooler, can not lower the CPU temperature even at max fan speed, may not work in terms of fan speed control with many motherboards, I don't see any reason why anyone would want to buy this cpu cooler. It's a complete waste of money and time!

Shame on SilentX!

1 out of 5 eggsNot much over OEM fan

Pros: Easy installation. Very quiet

Cons: Although it has a lot of surface area and SHOULD provide enough cooling, that really is not the case. Thermal transfer is diminished due to the distance from the fan to the fins. Your better off spending more for a 120 mm cooler with more direct air flow. (I'm an expert in thermodynamics btw)

1 out of 5 eggsNot as good as the stock fan...

Pros: Cheap

Cons: Much, much louder than expected
Doesn't cool as well as expected

Other Thoughts: Bought this for an AMD FX-8350 processor, as aftermarket coolers are always better than stock, right? Wrong. Even at the highest fan RPM the stock heatsink/fan was quieter than this one, and even at 25% speed it cooled more effectively at the same loads.

That said - if you got an FX-8350, don't waste your time. It comes with a Cooler Master heatsink that rocks. If you got anything else, I hope you don't mind a lot of noise.

4 out of 5 eggsOkay, Nothing Special

Pros: Does a good job with my 955. Temps are unchanged from stock.

Cons: Hard to clean dust from behind fan, have to remove the fan/motor to get to it.

1 out of 5 eggsComplete waste of money

Pros: It looks nice.

Cons: This fan sucks because it has a 3-pin connector. Unless your motherboard can sleep down fan voltages, this thing is going to run at full power and is extremely loud. Not impressed at all.

4 out of 5 eggsDecent

Pros: Looks cool. It's cheap. Really quiet.

Cons: Mine came with bent fins that I had to straighten out. I don't really think this better than the stock cooler I had. The processor runs about 5 degrees hotter than the stock one did. (I was using a 8350 stock cooler on a 7750 Kuma - just plain loud)

Other Thoughts: The main reason I got this was not for over clocking or anything intense. I had a client that was complaining about the noise level so I got this. No complaints so far from customer.

It is rather wide. It almost touches the first stick of memory.

This is a good product. Has very limited uses though. I would recommend this for any HTPC/LP setup.

3 out of 5 eggsIt works

Pros: its cheap, quiet and pretty easy to install

Cons: There is no copper core on this heat sink. I wouldn't recommend putting this on a higher voltage CPU (77W). The heat transfer would be questionable. I have mine running on a i7-2600S and havn't had any issues.
