5 out of 5 eggsCood Cooler & Rebate is Real

Pros: This upped the number of towers in my home with Zalman water/liquid CPU coolers to four. They all work & I have no complaints. I keep reading about a clicking sound & apparently my 68 year old ears that lost their ability to hear mid to high frequencies long ago have solved that problem.

Rebate - I received my cooler Sat Jan 17, did the online part of the rebate process the same day & got two email confirmations the same day, & mailed the paperwork/UPC Mon morning, got an email that my rebate had been processed Fri Feb 13, and an American Express $20 cash card showed up Sat Mar 15th. Certainly not instantaneous & a hassle, but it worked as advertised

Cons: None.

Other Thoughts: I'm never going back to air cooling.

1 out of 5 eggsREBATE SCAM

Pros: easy to install, probably the best cooler in its price range.

Cons: the company denies rebates purposely, i cant imagine how terrible the customer support is, this is a frustrating reason why I cant buy anymore of their stuff.

Other Thoughts: I personally own about 20 pcs and counting, too bad zalman will not get anymore of my business.

Manufacturer Response:

Dear valued customer,

We sincerely apologize for the issue. Please contact our customer service e-mail or via toll free number 1-888-925-6266 for further assistance.

Thank you.

Best regards,

Zalman USA Customer Service

4 out of 5 eggsCan Do The Job

Pros: Easy to install despite cryptic less than complete documents.
Price with rebate is quite good.

Cons: Works poorly for a water cooled unit if you run on the single fan, but once we added the 2nd fan it began to work as advertised.
2nd fan brought idle temp down 4 degrees and under high frame rate gaming it made a 20 degree difference!

Other Thoughts: This is with an AMD 8 core cpu, you may be able to do fine with the single fan if you have a quad core.

4 out of 5 eggsCareful with 1150 Sockets

Pros: -Been quiet, at least so far. Certainly can't hear it above the fan noise, at least.
-Radiator fit on my case without any fuss, looks like there's a good amount of space if I feel like adding in another fan for push-pull

Cons: Backplate does not have a configuration for 1150 sockets. It is possible to fit it on, but it requires some considerable finagling and some might not be comfortable with the amount of force required to shape it to fit the sockets.

Other Thoughts: Still getting my build sorted out with drivers and the like, but before doing any overclocking I'm getting CPU temps of 20-25 celcius. Pump noise has been cited as a common problem but I haven't had any issues with that at least so far, I can't hear it at all above my fans. That said my case is a C70, which is a great chassis but isn't exactly the most quiet option out there. When turning the computer off I can hear the pump quietly running down for a few seconds, other than that I wouldn't notice it at all.

5 out of 5 eggsZALMAN LQ-310 Water/Liquid CPU Cooler 120MM

Pros: Ease of installing, quiet, does what it is designed to do.

Cons: fan could be better for cooling the radiator down faster

Other Thoughts: I bought this cooler to see if I wanted to get away from the fan/metal fin coolers. I installed it on an stock AMD 8350 cpu and the singe fan when playing games, has difficulty keeping up. I added a 2nd high volume/low noise fan and now the radiator doesn't get hot. I would have knocked an egg off for this but for most applications the radiator cooler would have been adequate.

5 out of 5 eggsRadiated and Satiated

Pros: After determining the AMD portion of the directions for my 9590 Processor and Sabretooth motherboard, the install was quick and easy. Make sure not the make the motherboard screws too tight! Started it up, temperatures held steady and so I went to work.
Returned 5 hours later to find everything still stable and cool. Went into bios to turn up the overclocking. Ran 2 browsers with 10 tabs each, ran Steam and Origin to run Awesomenauts, SimCity, Battlefield 3, Splinter Cell Blacklist, Team Fortress 2, Dragon Nest and The Sims 3 at the same time. Temperatures never exceeded 35 degrees Celsius.

Cons: Radiator screws were a little difficult to screw in through the case. Instructions a little confusing given the differences between Intel and AMD.

Other Thoughts: After my own stress test I found myself pleased with both the installation process and the performance of this product.

2 out of 5 eggsPoor quality. Lousy Customer service

Pros: Cheep (if rebate was honored), works well (keeps AMD 955 CPU fairly cool).

Cons: Noisy. Pump is much nosier than comparable Thermaltake used on another unit. Zalman denied rebate. Poor customer service.

5 out of 5 eggs

Pros: cheap
at idle my quad core is 40c under load 65c

Cons: needs a extra set of long fine thread screws other than that no problems

Other Thoughts: With the low price of this close loop cooler and reliability you cant go wrong its perfect for entry level over clocking & mid level gaming ZALMAN and newegg will see more of my business :)

4 out of 5 eggsWorks Fine with Intel LGA 1150

Pros: Advertised specs on this model claimed support for LGA 1150 but instructions only covered 1155, 2011, 1366, and 1156. Evidently the instruction sheet had gone to press before introduction of 1150 so I was a bit concerned with compatibility. Turns out the install process is exactly like 1155 except that the backplate will only fit if it is mounted off-center. Once I got past this, came together just fine. Temps on my OC'ed Intel Pentium G3258 (3.2GHz==>4.2GHz) are below 50C at idle.

Cons: This is my second LQ-310. The first has worked flawlessly for almost 2 years on my main system i7 extreme LGA1366. After installing the second unit, I noticed a distracting low-frequency pulsing sound that was not present on first unit. Eventually took care of problem by moving to closet but knocked off an egg anyway.
