as everyone mentioned, it's a tough one to install

Anonymous, Newegg
4 March 2015
  • Pros: I did what everyone recommended and I got it ontop of my 1150 Intel successfully. Make sure, as mentioned by others, install when board is not in the case. Makes it easier to do. Read very very carefully the instructions as well. This is my sixth generation Zalman, and by far the most complicated...
  • Cons: Very difficult to install

Good cooler, bad install method

American E., Newegg
27 January 2015
  • Summary: If you have another installation method other than the bracket and hex head screws ... buy this cooler.
  • Pros: Great cooler, period! I bought a Zalman two bearing cooler in 2006 and it worked flawlessly the whole time I owned it. The only reason I bought this cooler was because I rebuilt my old desktop two months ago and wanted a new CPU cooler to go with the new build. The first Zalman worked great and I...
  • Cons: Installation method on this cooler was direct but a real pain. Luckily for me I still had the steel clip that was used to install the old Zalman cooler so I used that instead of the brackets and hex head screws sent with this cooler. The hex head screws were not deep enough to keep from stripping.

instalation sucks!

Michael d., Newegg
16 January 2015
  • Summary: use a better grade metal, this nice fan isn't worth anything if you can mount it properly.
  • Pros: nice fan but...
  • Cons: The installation hardware is made of butter!! they use Allen screws to mount it to the bracket, due to the size of the fan it isn't easy to get to the screws and the metal is SO soft the hex head strips out quickly. this is made worse by the fact I had a DOA board so I had to do this twice. I don...

Does not fit spects

edward b., Newegg
11 January 2015
  • Summary: This is my last Zalman Cooler.
  • Pros: I have been using these Zalman coolers since this company has been in business. Every one was fantastic.
  • Cons: In the Specifications it states that it will fit an LGA 1150. That is a lie. Its not Newegg's fault. It is Zalmans. I have one on another computer that is for the 1150, the fitting are nothing as they should be. Even the instructions don't say it will fit the 1150, which the Specifications say it...

ZALMAN 120mm - Blue

Dave D., Newegg
29 December 2014
  • Pros: I am running this on an AMD FX-8350. When the processor is maxed out for an extended period of time the max temp I’ve seen is 40c or 104f which is pretty good since the processor is overclocked to 4.35Ghz when maxed vs. the standard 4Ghz. When it is under normal load it runs between 28c – 32c or ...
  • Cons: Blue LED doesn’t work. First time using a Zalman. Installation was a pain but the payoff was worth it. I wound up having to bend down the mount tabs to get to the point were the screws could reach.

26 December 2014
  • Summary: I've got another build later this year and it'll have a Zalman in it!
  • Pros: This is the 4th Zalman cooler I've bought. The oldest one has been running for around 10 years. All of them have run quietly and kept my OC's nice and cool. Love the included thermal paste. It might even be better than the Arctic Silver 5 I usually use. We'll see.
  • Cons: The installation can be a little tricky. Make sure you understand how the brackets fit and then do a test-fit before putting on the thermal paste. The holes lined up perfectly with the 1150 socket. Some manuals describe the airflow one way while illustrating it the other. Make sure you have it po...

  • Summary: I'll never go air cooled again. Water blocks mount soo superbly and keep the processor soo cool.
  • Pros: Looks really nice and temps are ok
  • Cons: Rattles after a year, the sound is really irritating, Installation will make you wanna break something--its sooo frustrating.

Things to Remember

Anna T., Newegg
19 December 2014
  • Summary: You must remember that every fan or cpu cooler will have a drawback other wise there would never be a competing brand and you wouldnt be searching. However i would like to mention that this fan is great because of its shear size and copper material.
  • Pros: see other thoughts
  • Cons: see other thoughts

No problem

Edward K., Newegg
17 December 2014
  • Summary: This was my first install of an aftermarket cooler. I elected not to use the optional adhesive pad to hold the backing plate to the motherboard. Instead, I hung the case half off my desk so that I could hold the backing plate in place with my hand while aligning the screws with my other hand.
  • Pros: Looks neat. Big. Works as advertised. Fits 1150 sockets, even though they are not listed on the package; uses the same holes as the 1155/1156. No memory or case clearance issues on an ASRock Fatal!ty Killer Z97 in an Antec 300 case. Installed over a 4790K processor, not that that matters. Others ...
  • Cons: As other have pointed out, it can be a little tough to install. Specifically, it's a bit tricky to get the screws lined up and started.
