1 out of 5 eggsDied within a year of use.

Pros: None

Cons: Pump died within a year of use. All of a sudden my PC gave a overheating warning and shut down, the pump stopped circulating coolant. Had it just about 1 yr when it failed.

3 out of 5 eggsQuiet cooling has never been so loud

Pros: Works great! Keeps my 140w Haswell-E well within safe limits even at minimum pump and fan RPMS. While there are better coolers out there, it is absolutely overkill for any sane user, and even overkill for most sane overclockers.

Cons: The pump cavitates constantly at all RPMS. With no reservoir to catch air bubbles in the cooling loop, the thing is constantly sucking up air bubbles and pushing them through the waterblock, leading to a noise not dissimilar to a drunken man relieving himself in a back alley. When I first tested the unit before installation, it cavitated so loudly I swore it was broken. It was not broken, but the cavitation noise was louder than the pump noise itself.

I mounted the radiator in the top of my case, all according to Zalman's preferred methods After about a week of the pump running at 50% (1000 RPM) I was pleased to discover the cavitation actually stopped, and the unit was blissfully quiet. After about a month, the cavitation returned, quieter than before, but still louder than the pump itself.

While the unit continues to perform just fine, the fact that it's constantly sucking air gives me concerns about how many years it's going to last before performance IS impacted.

On the subject of noise, The cooling fans included are high speed and performance, but of dubious build quality. One of the two fans on my unit already has a failing bearing. Replacing the fans is tricky, they mount to flimsy plastic, and their mounting screws go through the fan and into the heatsink, rather than through the heatsink and into the fan. The unused mounting holes on the other side of your replacement fan will get in the way of you putting the screws back in. You'll have to dremel them off, or use a screw driver that can fit through the mounting holes of the fan.

I have always been a fan of zalman products for how incredibly quiet they are. The Reserator 3 falls flat on it's face though in this respect. While the pump and the fans are both quiet enough at low RPMS, Zalmans inability to more completely purge the loop of air makes the entire unit unpleasantly loud. Liquid cooling loops with a reservoir to catch any air bubbles trapped in the loop simply don't make the kinds of noises the reserator 3 makes.

Other Thoughts: You really cannot go wrong with how well this unit keeps your CPU cool. It is a very capable cooler and is pleasing to the eye as well.

Unfortunately the Reserator 3 really fails to live up to Zalmans reputation for quiet cooling solutions. The cavitation noise is really disappointing, and could possibly be fixed by bleeding the loop more carefully at the factory, or the addition of a small internal reservoir in the radiator to catch stray air bubbles and keep them from being sucked into the pump.

In a quiet room, when all your PC's fans are turned to minimum, you will be treated to a constant irregular trickling that is far more annoying than ordinary fan noise, and significantly louder than any fan in your case.

1 out of 5 eggsFailed in 4 months

Pros: It works OK when it works. If you hear a buzzing noise coming from your computer you should refer to the Cons.

Cons: It has a limited life span and poor support.

Other Thoughts: Zalman will not respond to warrantee support. This tells me the problem is common.

3 out of 5 eggsNoisy

Pros: Very good at cooling the CPU. Nice adjustable bracket to fit motherboards with large heat sinks, memory, etc...

Cons: Very noisy fluid sounds when running. It sounds like bubbles are being flushed through the pump constantly. No other liquid cooler that I have used is this noisy. The bubble sounds usually dissipate after a few seconds of running, but not this one. Would be 5 eggs if it were quiet.

5 out of 5 eggsZalman Reserator 3 Review

Pros: Fantastic Liquid Cooling
Cool and innovative Design
Attractive appearance
Sturdy construction
Closed loop system that is maintenance free

Cons: Price is a little higher compared to other options.

Other Thoughts: Let me start by saying I am a loyal New Egg Customer. My 1st unit was damaged in shipping and New Egg promptly took care of me. So Reason #1 to shop here.

Once the 2nd unit arrived in perfect shape I began the install. Install is pretty straight forward you will just need to make sure you have space. Anyone who can build a PC should not have trouble with this.

NOTE: The radiators and fans are THICK u will need space. Did I mention u need space????

In my AMD Scorpicus Mid tower I had to massage my case with a dremel by opening some new "Air Vents" in the top so I could shift the unit such that it does not touch the Ram. Also had to "trim" the fins on my Ram. (Gotta Love a Dremel) With the unit mounted and in place and everything reconnected and doublechecked, I fired the beast up. I am working with the following.

Asrock Fatal1ty MB,
32gb Gskill Ripjaw Ram
dual 240gb SSD Hard Drives
500gb Seagate barricuda
Soundblaster ZX Sound Card
AMD Radeon R9 295 X2 8gb Video Card

So system boots fine and using the utility that comes with the Fatal1ty MB, I see my temps have dropped way down.
So now to Test...

Prior to this cooler using a Cooler Master Seidon 120 I would get 60 degrees Celsius using Star Citizen.

Stock clock with the Zalman.... 42/44 degrees Celcius.

So now I overclock.
After numerous settings, voltage chages, and reboots
(Won't bore ya with the details)
I now have my FX 8350 running stabily at 4.4ghz and on normal games my temps are 43/45 degrees celcius and Star citizen maxed out runs 54/55 degrees celcius.

So the effects are clear. This cooler can get the job done. I wish it would have been offered at a 99.99 price point vs the 134.99 price I paid, but you do get what you pay for as they say.

4 out of 5 eggsAlmost Perfect

Pros: Keeps an aging 8350 quite cool @ 4.4 gHz 18c Idle up to 48-49c on full load in AOD stability test, for days if it pleases.

Assembly parts included are of excellent quality.

Backplate mounting was quite frankly, genius. Got this in by myself. (use that box it came in to sit it on and keep it cpu level while you work at the side panel of the case)

Cons: Included 120mm PWM fans are complete and total garbage, it's the reason for the docked egg unfortunately. It's so disappointing, in such a high cost AIO cooling solution, especially from Zalman. The cooling of the fans isn't poor, but they also aren't anywhere near what they should be; especially for the noise generated from the materials they are made from. They are made from some kind of very rigid hard plastic, I couldn't find any fan setting, from profile to full bore; that didn't make that slight plastic mechanical tick. The fans were easily replaced and the rest is history. Also! While the fans "can" be replaced, be careful. The plastic I mentioned is also what shrouds the radiator itself. If you go to replace them just take it slow and brace the plastic around the rad with your free hand. It does NOT like torque when replacing the fans. Be warned.

Other Thoughts: Have an i7 4790k on its way. I'm hoping with the lower TDP, it'll serve me even better when that arrives.

Also, it has to be noted, my case is a Thermaltake Core V71. There is a rail offset from the motherboard running on top of the inside of the case. Make sure you have the room and especially the width. As it is, with my LP memory it still barely has an inch between the fans and the top of the memory heatsink and this case is huge, so be aware. VERY IMPORTANT: Read the Instructions carefully and make sure you are using the correct screws for the right step/socket. Very easy to mix some of these up to the untrained eye.

4 out of 5 eggsMy First Pre-Assembled Liquid Cooling System... and I'm old.

Pros: Nice and gigantic... Well engineered and designed as most Zalman products are. My ancient liquid cooling system started leaking, so I had to switch to the CHEAPO stock fan. Jeez, AMD fans are terrible. My FX-8350 was getting absolutely annoying with fan noise under half load and even after re-seating the fan with a better thermodynamic compound, it still sounded like a Dyson Airblade when just watching TV. After some good success installing one of their smaller offerings in a friend's rig, I decided to give this a go to shut this thing up for good. The proc would hit 65C at half to 3/4 load before as if the fan wasn't even built for the proc and I was running stock speeds. With this, I've never seen it crack 40C even while gaming. That's good in my book and the installation (for proper cases) is a breeze.

Cons: From a design standpoint, I would have liked to see the ability to easily reverse the mounting. I knew ahead of time my case wasn't tall enough with clearance between the top of the motherboard and the case, but I have an Antec LANBoy (dumb name) whatever case that is just a skeleton and mesh that I just sawed into the top and the fans have enough flow, but they are pushing down. Obviously not the optimal top exhaust everyone should have, but two 120mm rear and side fans pull well and oddly enough, my GTX980 runs cooler now that it doesn't have to share airspace with a hairdryer above it.

The instructions aren't "hard" for enthusiasts to follow, but they are a bit "Ikea" and tiny. I also had one bad LED on a fan upon arrival, but of course this is after you install this thing and Newegg offered to RMA, but I wanted to hit Zalman to just replace the fan. At the time Zalman's entire website was down which was weird, but hopefully they will just "be cool" and send me a fan.

Other Thoughts: I was happy with the results of this and purchased a second one for my i7-980X that I am transitioning to a home automation and media server.

5 out of 5 eggsAwesome!

Pros: I'm an engineer, and I run a gaming system because it's the only system that can keep up with my number crunching. This system keeps my Core I7 Extreme 8-Core CPU nice and cool running at full throttle!!!

Cons: Fans are a little loud, but you can adjust the speed in bios. Doesn't seem to be made to fit any case, really. I have a "Cooler Master" Case (sick case) and it took me all of 5 minutes to modify it with a drill and shears to make it work.

Other Thoughts: Worth the money. I always recommend Zalman cooling products - I can take a little fan noise over a hot CPU any day!!

5 out of 5 eggsWorth the time and effort

Pros: This cooler keeps my I7-5820k Proccessor overclocked to 4.2ghz between 15-and20c at an idle (the 20c is only on one core #2 which just seems to run hotter than the others.) at a full load burn in test does not go above 50C!

looks wonderful with the blue leds on fans, and on the center block that goes to your cpu.

High quality contruction and parts everything is solid and durable the closed loop system looks like it will not leak to me.

quiet even under a heavy load does not sound bad definantly a better tone than a air cooler too.

Cons: huge, but you should know this already if your looking for cooling of this magnitude for your computer why would you have a small case?

brackets are sometimes hard to keep the snaps and screw holders together but the bracket is wonderful to match to all sorts of cases as it is adjustable so not too much of a con just part of the time to install to make it right.

take your time do it correctly, install your ram and other things first!!! or you will have to take it off serveral times like I did.

Other Thoughts: would definantly purchase again no complaints for me and this is my first liquid cooler managed it worked in system first try no leaks
