In this review we have tested the Zalman CNPS 5000+ Cooler and measured the temperature results with our test setup. Additionally you can listen to an embedded MP3 fan sound sample of the fan on the respective heatsink.
|Overall size in L/B/H||+ 90/64/72 mm The heat sink protrudes laterally over the base due to the mounting – see Fit for Fan|
|flow rate||+++ 27 CFM (~5600 rpm)|
|noise level||– 40 dB (A) No question, the fan is not a silent pedal, unless you use the supplied adapter cables to reduce the speed (at the cost of cooling power) Listen to the original version online:
Listen with the middle adapter cable:
The quietest version (100 OHM resistor) is no longer audible !!!
|assembly||—- This unique construction requires the removal of the mainboard, because the heat sink has to be fixed from the bottom of the mainboard with 4 screws. So it is not suitable for hobbyists who want to remove their CPU more often.|
|Cooling result||+++ Great cooling result, although I expected more from the complex construction. 40°C at 1,75 Volt CPU voltage and 44°C with 1,9 Volt Vcore at 1066 MHz.|
++ The 430 gramm heavy copper cooler from Zalman is pretty much the only cooler you can leave on the CPU with such a weight when carrying the PC around (e.g. for a LAN party), because it is screwed firmly to the mainboard. But if you want to remove the heatsink from the CPU, e.g. to change the bridges, you won’t have too much fun with it. Of course, there are also some cases where you can get to the bottom of the motherboard with a bit of luck, but that’s probably a matter of luck. In addition, not all motherboards have mounting holes next to the socket (check before!). The cooling result, however, showed good results throughout and can also be seen at the top of the coolers. Included in the delivery are 2 adapter cables with different resistors to reduce the speed, which lowers the volume of the fan on the one hand, but on the other hand also reduces the cooling performance.
Without modification it is unfortunately not suitable for Peltier elements ! Many thanks to Overclockers for the test sample.
And here a picture of the complete delivery:
