CPU Central heeft z'n Voodoo2 cooling article geupdate. Errug handig info voor als je heatsinks op je Voodoo wilt planten.
Hier wat sfeeropbouwende info:
Over time, I've collected a number of CPU heat sinks, most leftover from other projects. I have found that CPU heat sinks are cheap (esp. used heat sinks) and easy to adapt to many applications. When making a heat sink from scratch, there are many things that should be considered. For example the base of the heat sink should be on the thick side if the item being cooled is subject to short quick bursts of work (or heat). This 'thermal density' helps keep the item cool on the short term but can result in a 'damping effect' when trying to dissipate the heat to the air. In my case the only real thing that is of any concern is fin height. The heat sinks should not protrude from the card too far. I always keep the PCI slot next to hot cards empty but I still want lots of 'air' room around the card. I found that an older blue Pentium Pro heat sink was shallow enough for my purposes yet large enough to make four heat sinks of the size required.
When trying to get a minor improvement (as in this case) it is not necessary to make the heat sink much larger than the chip being cooled. In fact I some times make the heat sink smaller if the wattage is low and I have a little chunk of heat sink that will work. If you want to check the performance of your heat sink I would suggest getting an indoor/outdoor thermometer from Radio Shack. Tape the probe to the back of the card, directly behind the chip being cooled. If it isn't clear by the circuit layout it will be by feeling for the hot spots. Take before and after temp readings for comparison. A heat sink will keep the whole card cooler.
