How many of you have saved countless pennies and sold our own blood in hope to one day, shell out all of our hard earned money on a brand new processor that we can be proud of and call our own. *holds hand up high*

How many of us have also tried to skate by with the provided stock heat sink and fan that is included with our new processors? *once again, holds hand up high*

Today we are going to take a look at a product designed to do one thing and one thing only, cool our hot PCs.

I have in my hand a new offering from a wonderful company named Spire Cooling Solutions. While this products name leaves very little to be desired, the SP792B12-U Kestrel King V is a nice looking product and I am anxious to see if the cooling power will cool as well as this thing looks. The first thing I notice is that it strongly resembles a stock heat sink from AMD but with slightly thinner fins. It is made of aluminum with a small copper base in the middle of the base of the heat sink. This cooler will be pitted in a no holds barred cool off with a Zalman 7000Cu as well as the stock heat sink and fan that came with my AMD 3700+ s939 at 2.2GHz.

For the tests, I ran CPU Burn-In for 35 minutes with the side door on my case closed and locked. After the 35 minutes ended, I immediately recorded the temps of the CPU and entered them into my super secret graph making program so I wouldnt forget.

Enough of the small talk, onto the temps!

Much to my surprise, the Spire did quite a bit better than the stock heat sink and fan. The Zalman did better in the end but its not quite a fair match since the Zalman is made entirely out of copper and has a much better thermal conductor. Seeing the similarities between the design of the Spire and the stock heat sink, I am surprised how much better the Spire cools the CPU over its aluminum brother.

I want everyone to know that these temps might seem a bit low, but I keep my house around 72 degrees and I have long said that ambient temps in your house and around you case make more of a difference than I think most people realize. I personally like it cool in my house so obviously it shows in my results. These tests were also used with Arctic Silver 5 thermal paste.

All in all, I must say that I am surprised that this did so well when placed head to head with the stock AMD heat sink. Having said that, if you have the money, I would opt for the more efficient, and more expensive, Zalman cooler. To wrap this up, I would not have any problem recommending this cooler to anyone who isnt satisfied with the performance of their current stock heat sink. I am giving this cooler an 8 out of 10 on our Techgage ometer. This is a quality, well made product from an equally great company. Many thanks go out to Spire Cooling Solutions.
