ZALMAN CNPS 7500 AlCu LED 2 Ball CPU Cooler

  • 1150-2300 RPM ± 10%
  • Pure Copper & Pure Aluminum
ICON Loading...

The Zalman CNPS 7500B AlCu, features a quiet, downward blowing 110mm ball bearing fan at the heart of a radial array of aluminum and copper convection fins. Blue LEDs give the impression of an alien powersource as they reflect off the metallic fins and demonstrate Zalman's reputation for combining style and function.

While the fan operates at low 32 dBA in its normal 2300 RPM setting, selecting Silent Mode using the included FAN MATE controller drops it nearly 50% to 17 dBA as well as eliminating vibration. With its unrestricted flow, it cools not only the CPU, but the RAM, VGA card, Northbridge and other nearby components.

Heat is drawn away from the CPU by the base of the heatsink and it is transferred up into the twin semi-circular arrays of aluminum and copper fins for dissipation. The 7500 AlCu is only 60% the weight of the pure copper model which lessens the possibility of stress damage to the motherboard.

  • newegg Excellent Cooling Performance The extra-large base and heatsink made of pure copper and aluminum conducts heat fast, plus a large 110mm dual-ball bearing LED fan to deliver superior cooling performance.
  • newegg Adjustable Fan Speed Controller The ZALMAN CNPS7500 AlCu comes with a fan speed controller (Fan Mate 2) so you can fine tune the fan speeds for the optimum balance between cooling performance and noise level.
  • newegg Universal Socket Compatibility As an all-in-one solution for PC systems, the ZALMAN CNPS7500 AlCu features broad compatibility with AMD socket 754, 939, 940 and AM2/AM2+/AM3 platforms, as well as Intel LGA 775/1155/1156 platforms.

5 out of 5 eggsQuiet

Pros: It's nice and quiet, looks halfway decent and does a good job of cooling.

Cons: Design doesn't allow for efficient ducted/directed airflow.

Other Thoughts: Did a good job at keeping an older 45W AMD quad core cool -- under 40C at full load in a 2U chassis.

I was running this for a while with an AMD FX-8150 (out of its rated TDP range, I know, I know...). When I had the hardware in a desktop chassis with moderate negative pressure inside the case, it was doing a passable job at keeping the CPU within operating temperatures, as long as it wasn't under full load for extended periods of time.

Once I moved the hardware into a 2U chassis, however, heat quickly became an issue (I once almost burnt myself on the chassis due to it overheating -- oops), and I was forced to purchase a different cooler. Obviously I didn't count this as a con because it's not rated for processors with 125W TDP.

I must disclaim, however, that even though I had some success with using this to cool a higher TDP CPU, I would not recommend doing it unless you know what you're doing and have proper temperature monitoring in place. I have full confidence that it would do well with processors <=95W TDP.

5 out of 5 eggsWorks for AM3+

Pros: The fan is quiet and the heatsink and LED are stylish.

Cons: I wish it had a four pin connect so my PC could auto-control the fan instead of a manual control

Other Thoughts: I built my PC to produce music and needed a quieter fan, and this baby works great. It makes some noise on its highest setting, but it keeps my PC cool on its lowest setting, so I am pleased with it. Also I was worried it wouldn't fit an AM3+ socket...but it does. Also if your fan header is 4 pin, the 3 pin wire will fit it. Very versatile.

1 out of 5 eggsQuiet???

Pros: Lights up, looks neat, moves air.

Cons: Noisier than the stock AMD cooler it replaced, even with the controller set around mid-way. What's the point???
Perhaps I got a bad fan? I'm unsure how noisy they generally are, but I can hear a distinct motor noise over the sound of the air off the blades, SERIOUSLY obnoxious, unless the fan's knocked all the way down.

Other Thoughts: Honestly I've sorta half-wanted one of these for awhile now, never really had a need until I built a media server that constantly runs in the livingroom. Guesswhat? I'm back to the stocker. With the cost and hassle of sending things back, I seriously doubt I'll bother. Gues I've got yet another spiffy paperweight.

5 out of 5 eggsdoes the job, but loudly

Pros: -Does the job
-doesn't obstruct anything
-pure eye candy if you case has a window

Cons: -This thing sounds like a jet engine.

Other Thoughts: It is VERY loud. I have the NZXT phantom and thought it was the 200mm fan, but after turning off the case fans, i discovered it was this. Its probably also due to the fact that my case has a grate, not acrylic as a window, so the air moving creates the sound. But when I'm engrossed in a game, it just fades out into the background, and i dont notice it unless i think about it, so the 5th egg stays

3 out of 5 eggsHuge, bulky, hard to install, but does great work.

Pros: -Very efficient cooler
-VERY quiet, even at maximum RPM
-Comes with external fan controller
-Blue LED light is pretty cool, if you're into that

Cons: -It's way too big.
-It's got one of those see-saw latches
-Very difficult to install

Other Thoughts: Bought this to mount on an ASRock ATX Z77 Pro3 motherboard. The huge dissipating fins on the cooler extend so far out that they cover the first RAM slot on the motherboard. Very glad I only had two sticks of RAM to put in the computer. Another thing is that it's VERY hard to get the latches to come down on the plastic bracket you mount the cooler on.

However, it's a Zalman product. It's one of the most efficient and quiet coolers I've ever strapped to a processor. Keeps my i5-3750k very cool and the external fan controller is WONDERFUL.

5 out of 5 eggsGood value, quiet, 3pin

Pros: This is a great heatsink/fan if you have an older motherboard with 3pin fan connection and not a 4pin pwm. Moderately quiet at low rpms. Comes with thermal paste.

Cons: needs clearance around the socket because it's a weird design. check dimensions before buying.

4 out of 5 eggs

Pros: Works great and looks beautiful. Replaced the stock cooler for the AMD FX-8150 and the cooling is better than I expected. I ran a torture test with Prime95 and maxed out the internal core temperatures to 51C.

Cons: Maybe a LITTLE loud for me, when accompanied by the other 4 fans inside my rig, but I guess I can't really complain when my rig stays this cool.

Other Thoughts: I Have this cooler inside a Thermaltake v9 black edition (replaced the red flan with a blue fan) and the whole rig looks fantasic!
I did want a different Zalman cpu cooler, but my case was a little too small for the other ones.

5 out of 5 eggsChilly con carne

Pros: Chilly: Much cooler than stock heatsink & fan. Design allows for heat dissipation in all directions, cooling memory, N. bridge and backside of video card. It fits in my HTPC case (Thermaltake LANBOX Lite VF6000BNS) with clearance in all directions. External fan controller is a plus, though I don't use it. Dropped my CPU temps from 36c-54c to 28c-45c. 30c @ 0 RPM :D

Cons: Carne: BIG. Comes very close to (my) ram, so if you have ram heatsinks or fans, they may obstruct the cooler. Odd buzz in medium-speed spin.

Other Thoughts: Be sure, as I did, to measure your case to ensure clearance. Nothing is worse than being stoked for a part and finding that it doesn't fit in your case. It does function without the fan controller, it is just an extension of the power cable from the fan to the motherboard.
