Test Setup/Methodology

ASUS A7M266 w/AthlonXP 1700+ 11x133fsb@1469mHz and 11x140fsb@1542mHz
Crucial PC2100 512MB DDR RAM
GeForce 4 MX420
WD 20BG 7200RPM
Enlight 340w PSU
Arctic Alumina Thermal Compound
Coolermaster ATC-710 w/4 generic case fans

The system was run at normal settings. No overclocking. We'll save that for the 200 level course. Let's keep it simple and applicable to our needs. As far as the tests go, I used some standards.
The test programs utilized were my competent favorites, Seti@Home, Folding@Home, Sandra Burn-in and a new one I found recently (thanks, cjh) Toast. I must add a disclaimer here. Unless you know what you are doing, I recommend you do NOT run programs like Toast for extended periods of time. Without adequate cooling, you can fry your CPU. Neither I nor any webhost take responsibility for blah, blah, blah, you get the idea. The methodology for the tests consisted of taking measurements at specific intervals, listed here:

Before power on (baseline)
30 minutes after boot (idle temp)
After 30 minutes of testing w/each program (max temps)
10 minutes after test completion (heat dissipation)

These are not overly long tests since most people don't stress their PC's for extended periods of time. Generally, systems are on for a few hours a day and really stressed only when playing graphic intensive games or running one of the above programs.

Another data point I will gather is the thermal resistance of each unit. This is expressed as C/W, where C is the temperate in Celsius and W is the power in watts. This is used to measure the overall efficiency of the cooler. It basically tells you how many degrees your temperature rises per watt produced. The lower the better. In order to arrive at these figures, we take measurements from the system temps, CPU temps at max load and the power rating of the CPU, or wattage. For this test we use a power rating of 64w for my 1700+. Again, lower is better.

I will monitor the ambient (room) temps and case interior temps with a dual display digital thermometer. The system (motherboard) and CPU temps will be monitored by a program called Motherboard Monitor. This is available on the 'net and is a free download. I suggest you get it. It is invaluable for monitoring your system temps, fan speeds and voltages. Info you might need later on if you decide to pursue this hobby.

Okay, on to the testing. The results will be grouped into table format for easier reading/comparison. All temperatures are recorded in Celsius and both system and CPU temps were assumed to be equal to case temps before powering the unit up.

Conclusion/Summary

Boy, that's a lot of numbers but what do they mean. Let's see the difference change from idle temps to max load temps. For the Antec it rose from 50c idle to 60c max. That is a 17% change, quite large. Anytime you can get the change under 10%, you have a pretty decent cooler. As for the Akasa it realized an increase of 16%, from 48c idle to 57c max. Not so good either, but marginally better than the Antec. OK, so now I've discovered that the Antec is not as good a performer as the Akasa, but how does it stack up against the stock cooler? If you look at the average C/W for the stock hsf you will find it is around .51 C/W. Statistically speaking, it is a dead heat. Of course we all know the problem with statistics, there are lies, damn lies and statistics. The question you want asked is this: Should I exchange the stock cooler for the Antec. In a word, no. You will get no better results from this cooler than you would with the stock hsf. Save your money for some CD-R's so you can burn all of your favorite reviews on them:. However, since I love testing and refuse to throw anything out, I performed one additional test. There are no tables for it since I ran only the Toast stress test, but I replaced the low power fan with the high speed Delta from my Swiftech and charted the results. They were somewhat expected but surprising at the same time. Just how important is it to have a really good fan? Running Toast for 30 minutes with the Delta I achieved a high temp of 51c. A far cry from the 60c with the thin fan. My PC also returned to an idle temp of 46c instead of the 50c noted before. The Delta is a loud fan. You can definitely hear it whine where the Top Power fan supplied with the Antec is nearly silent. But with that silence comes with a price. You will notice higher temps and in turn decrease the lifespan of the CPU. I'm hoping you gained some insight as to your decision on coolers and came away with a better understanding of the importance of proper cooling. Take my results for what they are worth. My suggestions are just those, suggestions. Thus finishes another Blue-Collar Review. However, that's just my opinion, your mileage may vary.
