Evercool Buffalo CPU Cooler (HPFI7-10025)


Product: Evercool Buffalo CPU Cooler (HPFI7-10025)
Provided By: Evercool



Today we are taking a look at a new cooler from Evercool, the Evercool Buffalo CPU Cooler. This cooler is aimed at the budget market, and it should be very interesting to see how it performs compared to stock cooler as well as some more expensive coolers that we've recently tested.

The Buffalo cooler actually comes in three different varieties, but today we are looking at the recently updated HPFI7-10025 version which is designed for use with the Intel Core i7 line of processors only.


First Impressions:

Right out of the box you'll notice that the Buffalo CPU cooler is quite a bit smaller than some of the other Intel Core i7 coolers we've looked. The Buffalo isn't really a flashy cooler by any means, but with the red fan and black grill it looks decent enough and looks better than stock cooling by far.

As you can see in the picture above (left), the Buffalo doesn't come with a lot of accessories. In fact it only comes with a tube of thermal paste and that's all. All mounting hardware comes pre-installed on the cooler so pretty much all you have to do is put some thermal paste on your CPU and clip the cooler on and you're done.....talk about simple installation.

Installation & Test Setup:

Well the installation section of this review is going to be pretty simple, basically all you need to do is remove the old cooler, apply the included thermal paste and clip the new Buffalo CPU cooler onto your motherboard and your done. It really can't get any simpler than this and shouldn't take you any more than 10 minutes from start to finish. All the necessary mounting hardware for the Intel Core i7 CPU comes pre-installed so you literally have to do nothing except open the box and clip the cooler onto the motherboard. Motherboard removal is not necessary, however if you already have your motherboard removed from the case then installing the cooler will become even more simple.

I've included some pictures of the Buffalo cooler and a Radeon HD 3870 card just to show how big the cooler is in comparison to a fairly large video card. As you can see in the next couple pictures the Buffalo is pretty small when compared to some of the other coolers we've reviewed and space isn't going to be an issue with the Buffalo and should fit into pretty much any mid-size case.

Now that the Buffalo is installed, let's see how it performs in the next section.


Test Info:

For Intel (LGA1336) testing we will be using the Intel Core i7 920 CPU, which produces 130 Watts of heat. This could be considered a mid-range processor, and while most Dual-Core processors produce ~50-80 Watts of heat, this should give you a pretty accurate estimate of what type of temperatures a cooler will provide you with.

For both AMD and Intel testing, we have taken all temperatures using CoreTemp v.0.99.4. CoreTemp takes a temperature from the CPU core, and allows for much more uniform results across different motherboard and CPU platforms. These temperatures may seem higher than other temperature recordings; because chances are they are taking temperature recordings using the diode underneath the CPU, which isn't able to be as accurate, and can really fluctuate between different brands of motherboards.

For all tests we are using the Highspeed PC Top Deck Tech Station, and we are using no additional cooling in our testing. All temperatures are recorded in a controlled environment that is set to 23 degrees Celsius (73.4 Fahrenheit) to provide fair results between coolers.

For all tests we use Arctic Cooling MX-2 High-Performance Thermal Compound (Paste), we use the same thermal paste in all our testing so that we can keep our results consistent. If a cooler is shipped with thermal paste pre-applied, it will be removed and we will re-apply it with Arctic Cooling MX-2 to provide fair results.

Due to the low retail price of the Buffalo CPU cooler I wasn't really expecting much in terms of performance, so when I started the testing I had to do a double take when I saw the temperatures of the Buffalo cooler. At idle temperatures there is a couple degrees cooling improvement, however at full load the Buffalo was able to shave off 9 degrees over stock cooling, which is very decent (especially for a inexpensive cooler). I was pretty impressed with the results of the testing and the Buffalo cooler is a worthy investment for anyone with an Intel Core i7 CPU that doesn't want to spend much on a cooler.

Evercool Buffalo CPU Cooler Final Thoughts:

As soon as I saw the retail price of the Evercool Buffalo (at time of publishing ~$20.00 USD) my expectations for the Evercool Buffalo sank a little bit and I wasn't expecting much from this cooler. I was however proven very wrong by this small and affordable cooler, and as we saw in our testing it offered a 9 degree improvement over stock cooling and ran only a couple degrees warmer than the much larger (and much more expensive) Evercool Transformer 4 (Full Review Here).

The Buffalo cooler isn't the quietest cooler we've had on the bench, however it wasn't excessively noisy either, but due to the 100mm heatsink fan running at ~1800 RPM it does make a bit more noise than other coolers we've tested. In most cases you probably won't hear this fan over top of other system noise, but obviously for someone who has purchased other silent components this cooler might not be the cooler of choice.

As soon as you open the box for the Buffalo, you'll notice very quickly that it's a pretty simple cooler and right out of the box the cooler comes ready to install (all installation brackets come pre-installed). There is no additional mounting hardware for the Buffalo cooler, all you get is the hardware necessary to install this cooler on the Intel Core i7 line of coolers and a tube of thermal paste and that's all. It was actually a nice change not to have to sort through a pile of brackets to find the ones necessary for installation, and thanks to Evercool using the same mounting hardware as stock cooling the entire process of getting this cooler unpackaged and installed will be under 10 minutes from start to finish.

At the end of the day it's pretty easy to like the Buffalo CPU cooler from Evercool. While this might not be the quietest cooler we've tested, it is most definitely one of the most affordable cooler and offers much better performance than stock cooling can. Thanks to the extremely affordable price tag and the surprisingly good performance the Evercool Buffalo CPU cooler has earned out "Editor's Choice" award. If you're looking for a cooler for your new Intel Core i7 CPU that won't break the bank, you're going to want to check out the Evercool Buffalo CPU Cooler.
