great at cooling headache to install on an 1150

Henry I., Newegg
6 January 2015
  • Summary: Dear Zalman reps: please provide a better mount in your next design.
  • Pros: It fulfills its primary purpose of cooling my cpu very well.
  • Cons: Will not fit on an 1150 socket with screws provided. Impossible to mount the clip for the cooler onto the bracket with the 3x6mm screws. I went to the hardware store and got a couple 3x10mm screws and I was able to install it.

Nice HSF, but don't be suckered by Rebates

Kevin S., Newegg
30 December 2014
  • Summary: I paid a little more than it usually sells for, because Zalman promised a rebate through 4myrebate.com. Par for course for the dreaded "mail-in-rebate," they claim they didn't get my documentation, and requested I re-send. Of course I don't have a second UPC to mail, so I'm out $25 because of yet another shyster rebate company. Rebates: Not Even Once.
  • Pros: As usual, Zalman makes excellent HSF for overclocking enthusiasts. I had its sister, the CNPS9900MAX, in my last build, and while they're both very large chunks of metal, you cannot argue their effectiveness.
  • Cons: It's a very big HSF, so it won't fit in many cases. Installation can be a little cumbersome, so it might be easier to remove the mobo prior to mounting. Also, rebates suck.

it looks like it's keeping my new Intel CPU about 15 °C ...

Jaron Widman, Amazon
15 December 2014
  • Summary: Just installed this on my system, and when benchmarked, it looks like it's keeping my new Intel CPU about 15 °C cooler than the heatsink/fan that came with it. It's also a lot quieter when it kicks into high gear. However, while screwing this to my motherboard and plugging all of the cables back in, I managed to cut myself in about a dozen different places. I almost bled all over the inside of my computer. =0 So be careful!

Love the look, install is tricky

JEREMY S., Newegg
9 December 2014
  • Summary: I have owned several Zalman heatsinks over the years. I also have a few aftermarket coolers from other brands Given what you're paying for a nice looking aftermarket heatsink, this installation should have been easier. If you are starting a build from scratch or are willing to pull your motherboard out of the case then the install should go more smoothly. Get the processor and heatsink on your motherboard first, then install in your case.
  • Pros: Large copper heatsink looks nice Effective cooling Quiet
  • Cons: Compared to the install of the standard Intel heatsink, this Zalman install was difficult. I had a retail Intel heatsink installed on my G3258 which I decided to upgrade. I removed the existing Intel heatsink and processor in about 2 minutes. I then installed my new processor in about another minute. This Zalman heatsink required an hour to install. I had to remove the motherboard, then screw the retaining clip in. I then reinstalled the processor, applied the thermal...

Good fan, could need some more quality assurance

Tyler B., Newegg
21 November 2014
  • Pros: The little time I had it was awesome, went from a stock cooler where Overclock temps were around 60C to this, which brought the Overclock temp down to around 25C when combined with Arctic Carbon MX-2.
  • Cons: The fan rattled *a lot* so I removed the heat sink. Right after I removed it a screw fell out of the back of the bracket attaching the fan and motor to the heat sink. I looked through the central hole and saw that the screw mount had somehow been stripped out. this is probably a one in a million chance so I wouldn't worry about others having it too often.

excellent heatsink fan

Yilun D., Newegg
2 November 2014
  • Summary: I definitely recommend this product, as it provides excellent cooling temperature and air flow. Just make sure that after installing on your mobo, it will not hinder other hardware placement (e.g. RAM slots). Luckily, this was not the case for me, but it came close to the DIMM slots.
  • Pros: I have i7-4790K CPU and the CNPS9500 AT provides excellent cooling. Running at 4.0 GHz stock speed, idle temperature is generally at 20-23 degrees, and 100% cpu load on 8 threads generates no more than 58 degrees.
  • Cons: The installation is not the easiest compared to couple of other HSF I've used in the past (e.g. Cooler Master Evo). You must have access to the back of the mobo in order to insert 4 of the nuts for the socket mount to be installed on from the front side. The S clip which lies on the CPU will need to be pressed down hard in order to screw onto the socket mount (no need to be worry, it is meant to be bent-resistant). I made the mistake of screwing too hard on the S clip...

Nice affordable cooler

Rebecca S., Newegg
11 July 2014
  • Summary: Have since moved on to a Corsair H100i but this is still a very nice cooler.
  • Pros: Cools very well and was able to reach 4.7Ghz stable on my i5 2500k at 1.38v running around 75c. Not bad but better than expected for a relatively cheap air cooler.
  • Cons: When the fan ramps up, it REALLY ramps up. Fan can get pretty loud at 100% and even around 80%. Knocked an egg off just for the annoyance.

Its very cool!

Matthew H., Newegg
26 May 2014
  • Summary: As with other reviews, its sharp and like the taste of blood. Also you have to remove your motherboard from your case to install its "clip support".
  • Pros: My CPU runs at 71 F and is fairly quiet. Its worth the swearing you will do installing it.
  • Cons: Instructions are unclear. You really have to look at and study the picture and the instructions together to understand what the manufacturer is getting at. If you go by the written instructions only you will be sorry! That is why I subtracted an egg.

Excellent heat sink

P. Hinds "Amazon Consumer", Amazon
26 February 2014
  • Summary: This is a great heat sink and it is made of solid copper. It is one of the few, perhaps only, heat sink that you can find with a finely polished mating surface. There is no back plate in this kit. Instead, there are four pass-through bolts and tension nuts. There are four brass retaining bolts for the spring-loaded hold-down plate. The four brass bolts are short, and strip easy.
