Passively cooling graphics cards: A Radeon 7500 trimmed to be silent
Conclusion: Passive cooling
Equipping a graphics card with a passive cooler not only looks classy, but can also significantly reduce the noise level in the housing. Not a bad investment for people with a preference for silent PCs. You can probably use the ZM17-CU on other cards such as GeForce 2/3 or Radeon 8500. A prerequisite, however, is a continuous flow of air in the housing or possibly even the installation of an active additional fan. Because the almost 50 watt power loss of a GF3 Ti500 requires extremely good cooling. We cannot and do not want to give a guarantee in this context. The Radeon 7500 chip does not get particularly hot during operation, which is why the card ran absolutely stable at 290 MHz (retail clock) even with the case closed and without additional fans. However, the temperature rose dramatically when I continued overclocking. If you plan to overclock the card, you should therefore consider buying a fan right away. So you still have a source of noise in the housing. But a relatively large fan should be much quieter with fewer tours than the normal GPU cooler with more than 5000 rpm.
Conclusion: Active cooling
The combination of the ZM17-CU and an additional fan is certainly not a bad idea, but you should do without the CBF32 from GlobalWIN. The two fans owna gigantic delivery rate. But this also has its price. The computer gets so incredibly loud that you might think you're sitting next to a vacuum cleaner. This solution appears to be the most humane when the housing is open. Because if you close the side wall, the fans get too little air due to the unfortunate positioning, which increases the volume considerably. Even if you lined the housing with cork or another silencer, the double fan from Global Win would still be extremely loud. It is better to use an alternative, such as a quiet 80 mm fan. However, the graphics card and the powerful fans can be overclocked extremely well. At a chip clock of 342 MHz, the graphics card with the original fan sometimes showed artifacts. With the GlobalWIN CBF32, these are a thing of the past in connection with the ZM17-CU heat sink.
