Have you been looking to upgrade your cooler for your Intel Socket 775 processor or your AM2 processor? Are you looking for the utmost performance? Or maybe you are just looking for an upgrade from the stock cooling solution the manufacture has supplied? Perhaps you have a smaller case or maybe you do not like the idea of having a large paperweight attached to your expensive investment. Whatever your reason for upgrading your current cooling solution, you may want to check out one of the newer coolers that Evercool has recently come up with, the Evercool Buffalo. This cooler is going to be able to cool a wide variety of processors, from your dual core to your quad core processors on one of the most popular socket types (LGA775) that will also be able to work on some of the green sockets as well. I am curious to see exactly what the Buffalo is going to be able to do for me.


Closer Look:

When you take a look at the packaging that Evercool has decided to use for its new Buffalo cooler, you are going to see a very common cardboard box that has quite a bit of color on it to help make the package stand out from others that are out on the market. The front and the back of the package are exactly the same, they both have the Evercool logo printed in the top left hand corner. There is also a large image of the cooler positioned in the center of the package that is aligned towards the right side. Under the image of the Evercool Buffalo cooler, you are going to see the Buffalo logo with the text "Heat Pipe CPU Cooler" printed under it to help describe the cooler itself as well as the quote, "The Buffalo Will Show You Extreme Performance!!", implying that the cooler is going to be able to out-perform much of the competition. The two sides of the package are where you are going to be able to find more information about the cooler, such as the different applications that the Buffalo is going to be able to work on, such as the Intel P4, Pentium D, and Core2 series; the AMD chips that it is going to be able to cool are the Athlon 64, Opteron, Dual core Opterons and Semprons. There is also an installation guide located at the bottom of this side of the packaging, while the top right hand side is where you are going to be able to see what mounting hardware is included, the AMD or the Intel. The next side is where you are going to find all of the specifications and features of the cooler.









When you open up the package, the only two things that you are going to find are going to be the cooler itself that is held in place by two pieces of molded plastic to make sure that it does not bump up against the sides of the package during the shipping process and obtain any sort of damage. There is also a tube of Evercool thermal compound, which is going to help with the installation if you happen to be all out of your T.I.M. of choice.



Now that we know how the Evercool Buffalo CPU cooler is packaged and what comes with it, it's time to see exactly what this cooler is made of.

Closer Look:

Taking our first look at the Evercool Buffalo, we are able to see exactly how the tower style CPU cooler is set up. Taking a look at the front of the cooler, you are able to see that the black and red fan is able to cover all of the fin array, and extends a little over the top and the bottom, which is going to allow the air that is being pulled into the cooler to pass through all of the gaps in the fin array. This allows the cooler to be as effective as it possibly can be. When you look at the side of the cooler, you are able to see that there are two thick copper heatpipes that travel from the base of the cooler and go all the way up through the fins and extend a little past the top of the cooler. This is going go allow the heat to be evenly dissipated amongst the fins. The Evercool Buffalo already has the Socket LGA775 mounting hardware installed on the cooler, making it ready to be installed right out of the box without having to attach it yourself.



















The fan that comes with the Evercool Buffalo CPU cooler is a 100x100x25mm fan that is made by Evercool themselves. The fan operates at a rated 12v and runs at about 1800 RPM with a 10% varrance and only making aaround 23dBA of sound. The black grill on the fan is not very similar to the others that are out on the market. There is no backing to the fan, allowing the air to pass more easily through the fan.



On the top of the cooler, you are able to see the Buffalo logo, which includes the name of the cooler under two red buffalos that are standing overtop two black buffalo horns. The base of the cooler is made of copper, which is always a good thing, as copper is one of the best materials for heat dissipation. The base also has been polished to ensure its flatness and to make sure there are very few, if any imperfections in the base.



The Evercool Buffalo CPU Cooler is such a small sized cooler compared to others that are currently out on the market, that there is no way that anything inside of the case is going to block it from being positioned in any way you may want it.


Now that we know exactly what the Evercool Buffalo CPU Cooler looks like, it's time to see exactly how it is going to be able to perform against some of the other coolers that are out on the market.

To properly test the Evercool Buffalo CPU cooler, I will be monitoring the highest temperature of the processor at idle (little to no CPU usage), and at full load (100% CPU usage). For coolers that do not have a fan supplied, my idle test will be done by running the computer for 30 minutes and recording the maximum temperature during that time. I will be using OCCT:PK to simulate a full load. I will run a torture test for 30 minutes with the mixed (CPU and RAM) mode turned on, and gather the maximum temperature during this time. The temperature monitoring software that I will be using is Real Temp 2.60, as it reads all four cores, documents the maximum temperature for a period until you reset it, and most importantly, it reads the 45nm processor temperatures correctly. I will be taking the four highest temperatures that were produced during the test, and report the average of the four cores. The stock test will be performed using all the stock settings for the Q9450 @ 2666MHz. During the overclocked tests, I will be using 410MHz FSB with an 8x multiplier to give me 3280MHz overclocked speed, with a vCore of 1.34v. All the temperatures are measured in degrees Celsius.


Testing Setup:


Comparison Heatsinks:

NOTE: Some of the listed heatsinks were originally tested using an E6600; I recently re-tested and gathered new data after the switch from the E6600 to the Q9450. The new temperatures are represented in the graphs below.






The Evercool Buffalo CPU Cooler did not do very well when it  was compared to some of the other coolers that I have recently tested. This may be due to the fact that the Buffalo is so small, or maybe the fact that the cooler only has two heatpipes, compared to some of the other coolers that have anywhere from 4 to 6 of them. It was however, able to do its intended job - it was able to keep the processor cooler during both overclocking and stock speed testings, cooler than the stock 45nm heatsink that comes with the retail processors.


The Evercool Buffalo CPU Cooler has a few things that are always a good thing to have incorporated with a CPU cooler, such as the high power small fan that is installed and shipped with the cooler, that operated at around 1800 RPM at only 23dBA. I really liked how much attention to detail Evercool used when creating this cooler. They were able to pack quite a few features into such a tiny cooler, such as the large fin array along with the usage of two copper heatpipes that travel from the base and go all the way up through the fins and protrude a little at the top. The overall size of the cooler was quite small, which makes it perfect for someone looking to upgrade their stock cooler if they are going to be running their system at stock speeds, or if they are going to be using a smaller case with moderate overclocks; it would be perfect for an HTPC. The base of the cooler along with the heatpipes were made out of copper, which makes the overall heat dissipation properties of the cooler better than some of the others out there. The base of the cooler was polished to ensure a flat base along with making sure any imperfections in the copper were sanded out. The temperatures that the two heatpipes were able to yield were not quite as good as others out on the market. However, it did do what it said it would, and that was to cool the processor and did it better than the stock Intel cooler was able to do. The multi-platform design of the cooler makes it more valuable for people who may switch this cooler between a Socket 775 rig and an AM2 setup. There was however, only the Socket 775 mounting hardware included in the package. I would suggest this cooler to anyone who is looking to improve the temperatures generated with the stock heatsink/fan setup or if they are going to do a little bit of overclocking and are wanting to use a smaller case such as a Mid tower or HTPC case.
