HTPC Case Price Comparison

Zalman have bundled a manual in a sticker with the logo of the producer a tube of the Zalman ZM-STG2 thermal grease, the RC33P adapter and all the anchorages and things essential for set up on a wide range of sockets.

 

The RC33P is a unit which lets us to regulate the turning pace of the fan by decreasing the strength from
12V to 7V. Of program if you have a fan controller you really should use that alternatively for the reason that it offers extra than two settings.

 

ZALMAN CNPS9900A LED IN DETAIL

 

The Zalman CNPS9900A LED is manufactured pretty much absolutely in copper. The one of a kind piece built of aluminum is the upper component of the base.

 

As you can see from the pictures over the fins on the back portion of the heatsink is thicker than the front aspect. The explanation for this is that the copper fins of the back again element are the types responsible for evacuating the heat.

 

It took me some time to discover the two metallic legs that are anchored to the base and which maintain up the fan in the center of the two cylindrical copper fins.

 

In the back again part of the fan I located the label that displays the fan's product selection and its electrical qualities. In this circumstance Zalman has installed a 120 mm fan with PWM capabilities (in between 1000 and 2000 rpm).

 

Set up AND Checks OF ZALMAN CNPS9900A LED

 

The installation of the fan is rather easy and it took me only a few of minutes. When installing the fan on an AMD technique, you must 1st fasten the included paper clip, whereas with Intel techniques you have to also install a back again plate and the fasteners for each socket. I will not go into this even more here suffice to say that the installation is easy.

 

The other components I utilised for this analysis were the following:

 

Test devices
Processor AMD Phenom II X4 920
AMD Phenom II x2 550 BE
Cooling solution Zalman CNPS9900A LED
Motherboard Sapphire Computer-AM2RD790 - CrossFireX PURE
Graphic card Sapphire Radeon Hd 4890
Soundcard Auzen X-Fi Forte 7.one
Memory Kingston HyperX DDR2 1066 two×2GB T1 Series
Difficult disk Samsung SP2504C (SATA II, 7200rmp, 8MB)
Energy supply Zalman ZM660-XT
Case Cooler Grasp 690 PURE
I applied two unique processors for this overview (both equally from AMD). I measured the CPU temperatures the two in overclocked mode and with the factory settings.

 

In buy to measure the temperatures of the CPU I made use of the values from the internal sensors on the CPUs. It's the ideal way to get reputable readings. In buy to load to the CPUs to the highest, I applied the software package OCCT 3.one.

 

The fan speed was automatically regulated by PWM while in the check, reason why the velocity oscillated involving 1000 and 1600 rpm. These are the effects from the test:

 

As you can see from the graph previously mentioned, the Zalman CNPS9900A LED is a pretty powerful CPU cooler even however it's not the most efficient which I have examined. Even when I overclocked the CPUs, the CNPS9900A LED had no troubles what so ever to preserve the processors cool.

 

As I explained before, this cooler is PWM regulated. I monitored the speed while in the checks and the max it achieved was around 1500rpm. Even at that stage the noise degree was low. I turned up the fan manually to 2000rpm (max) and then the noise level was over my convenience degree.
