Replacing the wildly popular EFZ-80HA2, SilenX introduces the new and improved EFZ-80HA3! It fits in cases that simply cannot accommodate a large 120mm based heatsink, but doesn't sacrifice the performance you need to run your rig. Performs better than your stock cooler while operating at a lower noise, it's a perfect complement to your new system and ideal for those with moderate processing needs. If you're not running a highly overclocked gaming system, there's no need to spend much on a giant heatsink that will yield no benefits to you. The EFZ-80HA3 utilizes two 6mm heatpipes that directly contact the CPU and are intertwined to provide four effective heatpipes worth of thermal dissipation. A universal mounting bracket supports the widest range of current AMD and Intel sockets, including the latest multicore Phenom and i3/i5 processors.

SilenX has included an Effizio 80mm fan with 3rd generation fluid dynamic bearings for years of reliable performance and no need to purchase any additional fans, though you have the option of adding a second fan for more performance. The installation process is easy with a typical install time of under 10 minutes and does not require the removal of the motherboard.

  • newegg Ultra-quiet, efficient cooling With two 6mm copper intertwined heatpipes that contact CPU directly and anodized aluminum fins, the SilentX EFZ-80HA3 offers superior heat conduction and dissipation. The included 80mm fan with 3rd generation fluid dynamic bearings delivers 12-36 CFM air flow at a noise level of 8-24dBA, perfect for your moderate cooling needs. For higher cooling performance, you can add a second fan.
  • newegg Broad compatibility Thanks to the universal mounting bracket, the SilentX EFZ-80HA3 is compatible with the widest range of current AMD and Intel sockets, including Intel LGA775/LGA1155/LGA1156, and AMD Socket 754 / 939 / 940 / AM2 / AM2+ / AM3.

5 out of 5 eggsSmaller platform

Pros: perfect for a smaller sized surfing rig, it will cool a pretty large chip for it's small size, my 95 watt AMD quad idles at 23c or less and rarely goes above 40c under load in a 2 fan system

Cons: no

Other Thoughts: use aftermarket paste, i used regular Arctic Silver

5 out of 5 eggsblew me away

Pros: This cooler is so cheap I would never guessed what it could do. It keeps an A10 in idle temps of 28c and load temps <=50c. At first it did horrible and I thought that I might of did a great mistake in buying such a cheap cooler, but what a surprise it gave me.

Cons: Installing it isn't the easiest thing I have seen, and the hook thing is super cheap and just weak. But all in all it does make a really tight grip on the CPU which is a good thing....but I thought I almost broke my board because I had to apply so much force to get it on. I really heard a crack but it works so I think it is okay.

Other Thoughts: If you think this cooler doesn't do its job properly then use the line method when applying your thermal paste, it makes a world of difference. And of course never use the cheap paste that comes with your aftermarket coolers, especially this thing if the cooler is so cheap imagine how cheap the paste is. All in all really great cooler love it.

1 out of 5 eggsSilenX CPU cooler

Pros: The fan is quiet and moves air, I definitely recommend it for case fans.

Cons: Where do I start.

I got this cooler while putting together an old Phenom build. It looks like it would be a pretty decent cooler! Boy was I wrong. I couldn't figure out why my cpu was getting so hot "i will give temp figures later"! its fully secured down and very very tight to the point it hurts your fingers to put the dam thing on. So I said well lets throw some money at it to see if it will help.

I purchased 2 high CFM PWM fans with great static pressure and put them in push pull config and i also got some arctic silver thermal paste. well that didn't help it was idling at 38C and after a 15 minute load test temps peaked at 70C ...

So i took the cooler off and put the stock one on and viola it idled at 26C and 48C at load.

the cpu for reference was a Phenom II X4 965

4 out of 5 eggsvery good for cheap

Pros: I've used about 15 of these coolers for different builds, mostly when the chip is notoriously hot on stock cooling. This tends to drop it around 15C on average, making it the perfect choice to do a lot better than stock for a very low price.

The fan is very quiet and supports slower speeds very well. You don't gain a lot of temperature if you set the fan at 50% speed using the motherboard's fan speed management controls.

Cons: The thermal paste included isn't great. You'll get a few more degrees off by using better aftermarket paste.

This cooler just doesn't have the mass aka thermal capacity or total surface area aka thermal conductivity to air that is needs to be used for overclocking. I tried overclocking an unlocked AMD Vishera CPU and it got very hot after a minute or two of running at 100%. I would only use this cooler for much better cooling over stock coolers to increase the life of your motherboard, not for overclocking.

Other Thoughts: Considering how many of these I've used without problems, I suspect some of the negative reviews were due to incorrect installations.

5 out of 5 eggsEffective and cheap

Pros: This is a cheap cooler that works. Keeps the Cpu temp low. Comes with mounting materials for another fan to get a push pull configuration.

Cons: This is not for am3+, but can be made to work with some adjustments and bending.

Other Thoughts: This cant be beat. Bought for my wife's computer, which has a red theme. Perfection.

5 out of 5 eggsFirst time with SilenX

Pros: Silent, you can't hear the fan at all. Can fit in very cramped cases. Temperatures are nice on my Intel i3-2120 machine. You can mount an extra 80mm if you want, the box comes with the extra mounts for it. Heat sink design is well thought. For the price you get copper pipes.

Cons: I don't really like the "Pc CoOler" logo at the top of the heat sink. Makes me suspect that SilenX is just a rebadge from an OEM product.

Other Thoughts: For the price you can't beat it, name brand or not, the cooler worked wonders. If you are not overclocking or running a mainstream to low end processor this will suffice. I decided to buy this cooler after a lot of research. I just wanted to try something new, not the usual well known brands. All I have to say is that this is my first time purchasing a SilenX product and I am very pleased.

2 out of 5 eggsNotVeryGood

Pros: low profile, compact for a stand up cooler, fan is mounted on rubber mounts so its very quiet.

Cons: Quiet but still vibrated, could not cool the CPU unless idle. Idle at 40C but hit 70 on prime 95 after less than 2 minutes. Heat pipes and fins were hot so I know heat was conducting. Only has 3 conductor power tap, no PM.

Other Thoughts: Phenom II dual core with other 2 cores unlocked, it couldn't keep up with the heat. The fan was quiet but it was shaking a bit, could tell it was out of balance by lightly touching the shroud or heatsink - I don't think it would last long if I left it in (which I didn't). If you have a 65W CPU and you need to make it quiet, this might be your heatsink. More than that and you can forget it.

5 out of 5 eggs1 year and still strong, keeps up with CM's 212

Pros: I have this in a push/pull configuration for a gaming HTPC and keeps my AMD fx 6300 cool at 29 while boost enabled at 4100MHz. Awesome cooler and for $10 when i got it couldn't wish for anything better.

Cons: Not copper just aluminum. Would be 1000x better if it were all copper, but 100x as much.

Other Thoughts: Get this is you need a superb low profile cooler. Matches my CM Evo on my other machine but was much cheaper.

1 out of 5 eggsIt looks good BUT

Pros: It conducts the heat off

Cons: it doesn't cool the fan has no shroud to pull heat through plates. My 8 core processor hit 65 in three minutes when I pulled the plug. the copper stack was very hot. the fan was ineffective
