great value until

Keith B., Newegg
14 March 2015
  • Summary: Go big or keep it simple. Do yourself a favor and skip this one
  • Pros: Silent, smaller than most other liquid cooling options.
  • Cons: Just over a year of light use the pump decided it's not going to work anymore. Being that I paid nearly a hundred and twenty dollars for this I figured I would have gotten more use out of it. I have to use my phone to write this review because I'm still waiting on a new cooler to arrive.

Not So Good

Eric P., Newegg
16 September 2014
  • Summary: Only other thoughts would be to get something else that will last longer.
  • Pros: While it worked it kept the CPU cool
  • Cons: Pump died just out of the 2 year warranty.... Noticed the CPU was running at 90C at idle. OUCH!

Works Well, While alive

Vida P., Newegg
28 December 2013
  • 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.

Great customer support

Hayastan M., Newegg
9 September 2013
  • Summary: i am happy that i was able to get my parts replaced
  • 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.

Absolutely amazing

Alec L., Newegg
12 January 2013
  • Summary: Make sure you have a big enough computer case because its a little big and won't fit in an average computer case.
  • 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

Quiet & Deadly

Alex H., Newegg
11 January 2013
  • Summary: 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.
  • Pros: Quiet, efficient, Cold, Easy to install
  • Cons: None that I can think of

  • 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 prod...

Really Like It

Cristobal A., Newegg

  • 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.

Great Cooler

Carol H., Newegg
29 November 2012
  • Summary: 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.
  • 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

Rebate ??

robin a., Newegg
18 November 2012
  • 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.
