1 out of 5 eggsZalman Reserator

Pros: it worked as advertised for 1 year. very quiet and posts temps lower than stock heatsinks

Cons: Complete failure after 1 year (just enough time for the warrantee to run out) water pumps they use are complete garbage. dont waste your money on zalman products. oh its also humugous and undweildly, which was fine when it worked. not so much now that the zalman tech tells me its been reduced to "still a good reservoir?" bah humbug. id give it 0 stars if i could. even air cooling is more reliable, yuck

Other Thoughts: this thing just stopped working after about 1.5 years. industry MTBF on water pumps is 5-6 years. Not only did zalman not do anything to help me, but they advised i buy a 3rd party pump!!! even their tech people know the parts are are sub industry standard. I will never buy another zalman product, might as well buy a standalone pump and peice the cooling system together yourself. It will look better and work longer.

5 out of 5 eggsWhat should I do?

Pros: I've purchased this reserator and I try to cool 2 8800GTX video cards and my processor FX-60, but the reserator gets very warm,
my cpu temperature shows 54-55 C and motherboard 46 C when I just browsing the internet, I don't know about video cards because I can't measure the temps.(i've tried to use ntune and that program feezes my computer) I really need some advise what I should do to cool down my system.

Cons: none

5 out of 5 eggsWOW, just what I needed

Pros: This thing is absolutely amazing, it dropped my OCed E8400 temps by 10 degreess without a fan. I was using the Zalman 9500 (a very good air cooler) I was getting 58c (even more because I was getting accasional lock ups) using FSX but now I can't get it over 48c. I am well pleased. And this is the first day of use, when the Arctic Silver burns in the temps will go down more

Cons: None yet, it's a Zalman...it's all good

Other Thoughts: Those who say this dosn't cool good must not be getting a good seat on their CPU. I had to dremel down the mounting bracket so the block could clear a capacitor at the top of my EVGA 680i

I am running an E8400 OCed to 4.05ghz and still cant get the CPU over 48c and no more lock ups

4 out of 5 eggsCools very well. Easy to install

Pros: It cools very well. They say that you aren't supposed to put an 8800GTX on it along with the CPU. But, I did. I bought the Zalman 8800GTX (ZM-GWB) cooler to go along with this. It cools very well. My E8400 is idle at 27 degrees and 39 on a load. My 8800GTX is 45 idle and 55 under load. It was 65 idle with the stock cooler. The Reserator also is very easy to install. I had not a single issue with a leak. I do suggest the ZM-RF1 fan kit with it. Blowing a fan on it makes a difference. It's $30 here on Newegg. I got it for $22.59 from another site. I can't post it here. But, I did a Yahoo search it was the 2nd hit.

Cons: The pump went bad after 2 weeks of usage.

Other Thoughts: When my pump went bad, the American division of Zalman took a very long time to get back to me every time I needed their help. However, the Korean division was very helpful and quick. I would sometimes get responses from Korea within an hour. The American division took days and days to respond. What's happening to customer service here in the states?

5 out of 5 eggsAwesome product

Pros: Totally agree with other review. I have been using for 2 years. Not 1 single problem. I even hooked and unhooked it a couple of times. Completely silent. A lot cheaper than other reserators and works like a champ. Using a non conductive fluid called PC Ice by PrimoChill.

Cons: Bulky as all get out.

Other Thoughts: cooling my C2D 3.0 OC'd to 3.7 and my 8800GTX MSI Vid Card.

5 out of 5 eggsBeen working like a champ since 6/7/05

Pros: This product is still doing it's thing, works like a champ for nearly 2 1/2 years. It's totally silent no noise what so ever. Keeps an OC'd E6750 at 22C under load. Aesthetic wise it looks totally sick next to my TT Shark case.

Cons: Not really a con but you know you're not going to be lugging this thing around to lans and what not.

Other Thoughts: I'm running distilled water as per directions and have changed it out only once. Personally I didn't expect it to last this long, very satisfied with my purchase.

4 out of 5 eggsGreat cooler...but...

Pros: Great cooler, simple setup, totally slient! Keeps my SLI 8800gts cards and overclocked AMD6400+ nice and cool (after a few minor changes, see below)

Cons: Pump doesn't flow very well at all. I fixed this by adding a Swiftech MCP355 to the inside of the computer case. The inlet and outlet for the Reserator are right next to each other but this is eaisly fixed. Can be a hassel to move around.

Other Thoughts: The cooling tower looks great, even though it's pretty big, and the color matched my case perfectly. When I first installed it I noticed that my temps were very high at idle (55C-60C) and the Reserator tower was very hot bottom to top. After verifying there were no air bubbles in the cooling blocks I took a look at the pump and base assembly. From the factory the inlet from the computer (hot side) enters the Reserator right next to the pump outlet (cold side). This allowed the hot coolant to enter the housing and go right back to the computer with no chance to cool off! I fixed this by attaching a length of hose from the hot side (there's already a fitting inside the housing) and ran it up to the top of the Reserator letting the hot coolant out at the top rather then the bottom. This instantly kept my system at 40C max at idle. Still kind of high. I then added another pump inside the case and run both pumps together. This now keeps my temps to 30C at idle and 35C-40C under full load!

5 out of 5 eggssilent!

Pros: This thing is silent! only way to tell it is on is to look at flow indicator or touch the hoses, they make a soft vibration from the water passing through them. It is easy to install, just put it together, add water, and turn it on :] Dropped temps about 10c.. All i hear now is the fan on my ultra :] soon to be water cooled tho ! :]:]

Cons: The Water block provided doesnt come with brackets for am2 processors but theyre easy to make.

Other Thoughts: it is very easy to make a homemade bracket for am2 :] I took an old cpu backplate and used a hacksaw and made 2 small strips and went to mclendons and bought 4 2inch long screws annnnd used the 939 bracked across to my strips of metal. sounds like a lot of work but it only took 5min not counting trip to mclendons :]

5 out of 5 eggsBest computer purchase I've made

Pros: This was the single best computer item purchase I have ever made. This along with a fanless power supply made my computer inaudible. It was almost a lifestyle change because now I can hear what was going on in other rooms in my home. Added this to my Athlon 64 3500+ and idle temps dropped from 51ºC to 28ºC (ambient temp was 25ºC). Later I added the VGA block to my ATI X800XT and the extra resistance and heat brought my idle temp up 5 degrees. After about 2 hours of heavy gaming temps get up to 45ºC, but then fall down quickly when back to idle. I’ve never had a leak. I’ve changed out the distilled water about once every 6 months as a precaution. I’ve never used any kind of additives.

Cons: I first thought the power switch was a con; however I always leave it running. Those that had troubles with the pump might have turned their reserator off w/ the computer. Yes, non stop for over 3 years, so a switch on the system itself would not make a difference. Only real con is the challenge of moving the computer when the reserator is connected.

Other Thoughts: I wish Zalman had a hard drive cooler for the reserator. I’m about to upgrade my entire computer to a X38 board, the only components that will survive the upgrade are my case and reserator.

5 out of 5 eggsReliable Classic

Pros: The Reserator 1 was probably among the first silent, easy-to-install water cooling units available. Zalman has continued to manufacture and sell it with good success and after owning one, I can understand why. I am a third generation plumber, and I know a little about hydraulic engineering. I also build computers for my friends and family and this cooler was as simple as pie to install. All of the parts are heavy, over-designed, and first rate quality. I am running the Reserator 1 on my media pc with a dual-core Prescott that thinks its a hot-plate. With traditional air cooling I would get 50C-65C temps using the rig for gaming and high-def video. With the Reserator 1, I immediately got 39C idle with 47C peaks and my wife had the heat running full-blast in the room. The most beautiful part about this product is absolute dead silence. All I hear now is the DVD drive crunching away.

Cons: Not many, other than it is really big. I had to negotiate with my wife to get her to allow it in our living room.

Other Thoughts: This is a great product for home theater applications without a lot of expense.
