Are you working on building a new computer? Maybe you are looking to replace your stock Intel socket 775 HSF, but you don't know what to look for because you're working in a very small case or a HTPC. Well, Thermolab had your particular situation in mind when the company was designing the Thermolab Micro Silencer. This cooler is very small, and looks like it would be able to cool better than the stock cooling solution from Intel. I am going to put the Thermolab Micro Silencer up against some other coolers that are out on the market and see where this little guy stands.

Closer Look:  

The packaging for the Thermolab Micro Silencer is a very simple brown box with black print on two sides. The front and back of the packaging are completely blank. The two sides of the box are exactly the same and let you know what is in the box, stating that the cooler is for Socket 775 and that it is a Micro Silencer. The sides also state that the Thermolab Micro Silencer was made in Korea.  







On the top of the box, Thermolab's logo is printed with the slogan "Effective Thermal Management Solution" underneath the logo. When you open up the package, you are able to take a first look at the Thermolab Micro Silencer. You can see the two copper heatpipes that are going through the fins that are all covered by a fan.  



Now we need to take the unit out of its packaging and see exactly how it has been put together.  

Closer Look:  


When you take the Thermolab Micro Silencer out of its packaging, you are able to see that it is fairly short; it is just a little higher than the stock heatsinks that come with the new Intel 45nm processors. There are two copper heatpipes that connect to the base and run through either side of the heatsink's bank of fins. This is how Thermolab is going to ensure that the heat that is pulled off of the processor and is properly displaced and allows for more heat to be drawn off of the processor. Taking a look at the heatsink from the side, you are able to see that there is very little space between the 43 fins that are built into the heatsink.  









When you take a look at the Thermolab Micro Silencer from the top, you can see that the fan that is attached to the heatsink to cool it as it grabs the heat from the processor covers the entire top. This could prove to be a good concept as it will maximize how much area is cooled. On the bottom of the heatsink, the base is aluminum and is very smooth. Thermolab decided to put some thermal interface material on the base of the heatsink just in case you did not have any. This can be wiped off, though I will use it during my testing to see how well it works.

To properly test the Thermolab Micro Silencer, I will need to record temperatures during both idle time (little to no CPU usage), as well as during full load (100% CPU usage). I will be using SpeedFan 4.33 to gather the temperatures of the CPU cores. I will be using OCCT:PK to simulate the full load testing and running it for 30 minutes and I will let the computer sit and cool down for 30 minutes before gathering the idle temperatures. I will be testing the processor at both stock speeds with stock voltage settings, as well as overclocked speeds of 3.6GHz with the voltage increased to 1.46 volts. All the temperatures are measured in degrees Celsius.  

Testing Setup:


Comparison Heatsinks:





As you can see, this cooler was outperformed by the other heatsinks, except for the Nano Silencer, in each test. When you take a look at the size difference between the Micro Silencer and the other heatsinks it was compared to, it should not have been able to beat them or even come close. However, again taking a look at its size, it is able to remove the heat off of the processor better than the stock cooler provided by Intel.



The Thermolab Micro Silencer was developed and designed to be able to cool a Socket 775 processor and to do so with a very compact design. This it was able to do even better than the stock Intel cooling solution. The Thermolab Micro Silencer was beat out by every aftermarket heatsink/fan setup that it was put up against, except for its little brother, the Thermolab Nano Silencer; however, this is to be expected when you take a look at the size difference between the coolers. The fact that the fan on top of the heatsink covers all of the fins makes me feel more comfortable knowing that the fins are receiving all of the attention that the fan can give. I did like the fact that Thermolab decided to go with all copper heatpipes in the design of this cooler. However, I have a feeling that were the base of the heatsink also made out of copper, there would be improved heat transfer from the CPU to the heatsink base, and then to the heatpipes, allowing the heat to be displaced quicker and more effectively. I am a fan of the mounting brackets only being made for the Socket 775, as this makes it easier to decide which brackets you need to install on the heatsink, while at the same time it makes you feel more secure that the heatsink was made specifically for this socket and not just being a one-size-fits-all cooler. I would suggest getting this heatsink if you are not going to be doing any overclocking to your system and if you are going to be building a HTPC or a computer in a very small case.
