All right, lets get down to the meat of the matter. No noise is all well and good, but the bottom line question still has to be "Does it work?"



The victim today will be the Prolink GeForce4 MX440-8x board. It falls into the category that covers this cooler so we'll be able to see first hand whether or not it can keep up with a fan operated setup. But before we get into the results, lets take a quick look at the rest of the test rig.


Xoxide modified Lian-Li PC60 case


EPoX 8K9A2 Motherboard (KT400 Chipset)


Athlon XP 1800+ Processor @ 1870 MHz (Thoroughbred)


512MB Crucial PC2700 DDR Memory


Seagate Barracuda 40GB HDD @ 7200 RPM


Testing will be simple and straightforward. I'll begin by booting up the system and then letting the machine idle for 15 minutes. This will allow the system to stabilize and give me a reading for idle temperature. After this temperature is taken, I'll run the PC through a few runs of the newly released 3DMark03 benchmarking program. I figure that anything that can slow me down to 4-6FPS is surely enough to stress out the video board. The highest temperature recorded during this will be listed as the load result.


Ambient temperature throughout testing is a constant 23.0 degrees Celsius. All temperatures are being taken by means of a thermal probe that has been secured right next to the GPU. The probe won't be moved between cooling methods so that we can have some consistency in our results.

So far we're looking pretty good. While not a huge difference here, just the fact that we're cooling without fans and winning says a lot. But what happens when we crank up the load a little?

Once again the Zalman Heatpipe has won the day. Given, the GF4MX board being used cannot run all the tests in the newest incarnation of 3DMark, but it was still able to start boosting the temperatures up when trying its best. This just goes to show you that you don't have to have large fans in place to get effective cooling. Now of only we could get those CPU coolers working like this!
