Evercool Buffalo HPFI-10025 CPU Cooler Review

By testtcm | Last Updated: October 25, 2018


Evercool has a vast array of thermal solutions incorporating both air and water methods for numerous different components. Their CPU cooling solutions especially include a variety of different fin and heatpipe architectures compatible with most current sockets.

The Evercool Buffalo, from the LGA775 range, is a newer design that utilises a copper base, a 10cm pre-installed fan and an easy installation method. As a more mainstream cooler compared to the HPK-10025EA, some decent cooling is expected too so let’s see what it can offer…

Base Material Heat Pipe
Bearing Material Ever Lubricate Bearing (Long life bearing)
Speed 1800 ±10% RPM
Noise Level <23 dBA
Rated Voltage 12V
Weight 500g

Contents & Packaging

The black and red themed packaging reveals the product immediately complete with some red lightning forks and the somewhat suspect logo: “The buffalo will show you extreme performance!” – Evidently not the most imaginative.


The sides are much more informative giving the full list of compatible processors along with the installation instructions outlined by a series of images.

The features and specifications are housed on the opposite side with headings aptly enclosed by buffalo horns.


Just a solitary accessory accompanies the Buffalo heatsink; with the instructions printed on the packaging and the push-pin clips pre-attached (for different platforms a different model is required), the only thing that remains is a small tube of thermal paste.

Essentially the Buffalo is simple tower format cooler with dual heatpipes running through the aluminium fin stack. The fins are all uniform and fairly tightly compacted in order to still retain a high surface area without too high a tower.

This also compensates the fact that the heatsink is quite thin making it easier to use the push-pin clips when installing the cooler atop a CPU.


The 100mm fan comes pre-attached to the heatsink which is, in one sense, useful as it reduces installation time but it does mean that the fan can’t be exchanged for a different one if the user is after absolute performance or silent cooling.

Spinning at roughly 1800RPM, the fan has a maximum noise level of 23dBA – these are fairly average statistics and so a 120mm fan would have been a preferred option offering the same airflow but spinning at a slower rate.


The dual heatpipes are 6mm in diameter and arranged in the usual ‘U’ shape so as to dissipate heat to the fin stack as effectively as possible. The tops of pipes have aluminium caps with a large Buffalo logo printed on the top fin.


Protected by a thin plastic film, the base has a pure copper finish; a good choice of material due to its very high heat conduction properties. On the downside, it’s not the smoothest or flattest base ever produced but a good layer of thermal paste should fill in any small grooves.


The Test Setup:

Processor Intel C2Q Q9450 Quad Core @ 2.67 (stock) GHz
Motherboard Gigabyte S-Series GA-73PVM-S2H
Graphics Card XFX 8600GT
Memory Corsair XMS2 PC6400 (2x 1GB)
Hard Drive Seagate Barracuda 7200.10 500GB
Power Supply NOX Apex 700W
Enclosure Antec P183
OS Windows XP Pro 32bit

Installation is incredibly simple with just three steps to follow:1. Apply a thin layer of thermal paste.2. Place the cooler atop and push the clips into the holes around the CPU socket by pressing diagonal clips at the same time3. Plug in the fan header.



At Verdis Reviews, we test socket LGA 775 CPU coolers by booting the PC up into Windows XP and then taking temperatures in both idle and load states.

The temperatures are taking using Core Temp and averaging the four core temperatures. For idle testing, we simply leave the PC for 30 minutes and then come back and take the temperature readings. For load, we run prime95 for 20 minutes before taking temperature readings once more.

Finally, noise is that final factor that is tested; however, at Verdis Reviews, we are not yet at the stage where we can use high tech sound equipment and therefore, noise testing is left to the human ear – not the most scientific but it gives a good impression of how noisy the cooler is.

Ambient temperature was 18 degrees and a number of coolers will be used for comparison purposes.



The results are pretty encouraging with the Buffalo beating all the competition, save for the high end NH-U12P heatsink. This is clearly impressive for a small tower format cooler but clearly it isn’t going to compete with the more expensive, large heatsinks.

Considering its size and only utilising two heatsinks though, the temperature results are definitely impressive.

NoiseThe noise results weren’t horrendous but certainly not as good as the Buffalo’s cooling; in comparison to the Intel reference cooler, the levels are a little higher and the noise is noticeable. Overall, in this department it has to be said that there are definitely quieter coolers to be had.

CostAt just £15, the Evercool Buffalo is incredibly well priced though especially when looking at the cooling performance.


As a simple tower format cooler, the Buffalo does a great job in terms of raw cooling performance only falling short of the high end coolers. Compared to the similarly priced GlacialTech Igloo 5610 cooler, the Buffalo is able to keep the heat down by an extra 3 degrees on average.

Installation wise, the cooler takes seconds to install using the push-pin clip method and due to it’s lightweight nature, it shouldn’t have an adverse effects using this installation method such as bending the PCB.

Despite all of the positives there are a few negatives. Formerly, the noise levels are not what they could be and swapping fans doesn’t look a particularly easy process. Also, the fact that a different model is required for different platforms is annoying and I would much prefer all the mounting brackets to be included together.

All-in-all though, the Evercool Buffalo offers a fantastic price vs. Performance ratio and at just £15, there aren’t many coolers that can rival it at this price.
