2 out of 5 eggsWorks Well, While alive

Pros: Keeps the CPU cool, Little noise.

Cons: Died in 1 year 4months. Was hoping for a little more longevity from this product.

Id recommend having a backup cooler for when the pump dies, nothing worse than in the middle of work pc over heating and going down till you can find a replacement.

5 out of 5 eggsGreat customer support

Pros: This liquid cpu cooler is great.

Most of all Zalman's customer support was great. One day i noticed that my CPU's backplate screws were stripped so i went to Zalman support page and filled out a replacement parts form and about a week later i received all new backplates and screws.

Cons: can't think of one.

Other Thoughts: i am happy that i was able to get my parts replaced

5 out of 5 eggsAbsolutely amazing

Pros: Everything about this cooler is amazing I was able to over clock my processor from 3.8ghz to 4.4ghz and my temperature only went up one degree. It's also very quiet

Cons: None

Other Thoughts: Make sure you have a big enough computer case because its a little big and won't fit in an average computer case.

5 out of 5 eggsQuiet & Deadly

Pros: Quiet, efficient, Cold, Easy to install

Cons: None that I can think of

Other Thoughts: I got this for my new gaming rig for college. Works great and was installed within minutes. swapped out a back fan for it. It comes with thermal gel already on it and is ready out of box. It keeps my CPU at around 20-30 degrees Fahrenheit tops. Great for those who use heavy frame rate programs.

3 out of 5 eggsZalman

Pros: Good cpu cooler..keeps system cool and very quiet.

Cons: I didn't receive the Intel backplate in original package but was ok because was installing on an AMD. Upgraded to Intel I7 and need a backplate...well Zalman has no customer service at all. No phone number just an email address that takes weeks to get a response. I will steer clear of Zalman products in the future..

5 out of 5 eggsReally Like It

Pros: Keeps my CPU really cool. High 90s degree (F) in the summer, and mid to high 80 degrees during the winter. I know most people here prefer using Celsius.

Cons: The directions weren't the best.

4 out of 5 eggsGreat Cooler

Pros: 1. easy to install if you know what your doing
2. relatively quiet
3. good performance

Cons: 1. fan was DOA, had to use a case fan as a replacement
2. didn't come with enough long screws for push/pull config with your own fans
3. can be loud depending on ambient room noise

Other Thoughts: would have been nice to have a working fan come with it, also coming with two fans for push/pull would be nice like the Corsair H80.

4 out of 5 eggsRebate ??

Pros: Works very good. Keeps temps 31c at idle and never over 52c with a load.

Cons: Minus one star for rebate. Don't hold your breath waiting for it. I sent mine in over 3 mo's ago, recieved an email saying it was recieved and to expect a rebate. Said rebate is way over due. Bought 2 of them and will buy more if said rebate ever gets here. If not , will never buy from Zalman again.

4 out of 5 eggsCPU Liquid Cooler

Pros: 1. Cool
2. Quiet
3. Solid construction
4. Set it and forget it

Cons: 1. Bad instructions (more details)

Other Thoughts: I was actually very skeptical of a liquid CPU cooler that you don't go back and maintain. This thing is very quiet paired with a mobo that controls fan speed. The construction feels very reliable. I checked the tubes for how well put together it was and if it would leak and couldn't see any corners cut on how it was built.

The instructions were actually very detailed, but it was very confusing on how to put it together regardless. Luckily, newegg's video on top of the instructions helped put things together after I fiddled with it for over an hour.

FYI - makes sure the plastic tabs that hold the screws in are turned the correct way, or it will not fit the motherboard's premade holes. That was my major hangup. Aside the lack of detail on that small hurdle, everything about the product is great. I trust Zalman as a brand altogether, especially for a good product that is quiet. I expect this would help with overclocking, but I'm choosing to stay stock settings to have it quieter and cooler for lower power consumption in my gaming rig.

Idle: 21c
Load: 32c
