I want to build a htpc using an Amd 4400 65 watt processor. So silence is the key. I a looking for a fanless heatsink solution. Can anyone recommend a good heatsink?
Yeah, you need to let people which HTPC case you are using and also it's dimensions.
If the case is 5" tall then I would probably recommend the Scythe Mini Ninja which is 4.53" or 115mm tall. This is probably the biggest heatsink I would suggest for a 5" tall case 'cause you gotta remember that the motherboard will be sitting on top of spacers.
